What causes bones to fail to grow properly in length. Weak bones and skeletal deformities, bow legs and knock knees

Answers

Answer 1

The failure of bones to grow properly in length can be caused by a variety of factors. These include nutritional deficiencies, genetic disorders, hormonal imbalances, and chronic diseases.

One of the most common causes of weak bones and skeletal deformities is a lack of proper nutrition, particularly a deficiency in vitamin D and calcium. These nutrients are essential for the proper growth and development of bones, and a lack of them can lead to conditions such as rickets, which is characterized by bow legs and knock knees.
Genetic disorders, such as osteogenesis imperfecta, can also cause bones to fail to grow properly. This condition is characterized by brittle bones that are prone to fracture and can result in skeletal deformities.

Hormonal imbalances, such as those caused by thyroid disorders or growth hormone deficiency, can also affect bone growth and lead to skeletal deformities.
Chronic diseases, such as juvenile rheumatoid arthritis, can also affect bone growth and lead to skeletal deformities.

In conclusion, there are several factors that can cause bones to fail to grow properly in length, including nutritional deficiencies, genetic disorders, hormonal imbalances, and chronic diseases.

What happens to the sickle shaped red blood cells during a sickle cell crisis?

Answers

Sickle-shaped red blood cells become stiff and stick together, obstructing blood flow and causing tissue damage during a sickle cell crisis.

Sickle cell crisis occurs when sickle-shaped red blood cells, which are typically flexible and round, become stiff and sticky due to low oxygen levels, dehydration, infection, or other triggers. These sickle cells can obstruct small blood vessels, leading to reduced blood flow to tissues and organs, and causing intense pain, swelling, and organ damage. Additionally, the stickiness of sickle cells can cause them to clump together, further worsening the obstruction and tissue damage. Sickle cell crisis can also lead to other complications such as stroke, acute chest syndrome, and organ failure, making prompt medical attention and management essential for those with sickle cell disease.

Describe transcriptional termination in eukaryotes? Is itthe same as in bacteria?

Answers

Transcriptional termination in eukaryotes is different from that in bacteria.

In eukaryotes, transcriptional termination occurs differently from bacteria. Instead of a specific termination sequence as in bacteria, eukaryotic genes have a more complex termination mechanism involving the cleavage and polyadenylation of the pre-mRNA transcript. Once the RNA polymerase II reaches the end of the gene, a signal is triggered to cleave the pre-mRNA transcript downstream of the polyadenylation signal site. The poly(A) tail is then added to the 3' end of the cleaved RNA, which signals the end of transcription and promotes stability of the mRNA. Additionally, eukaryotic transcriptional termination is influenced by chromatin structure and other regulatory factors, making it a more complex process than in bacteria.

What is the second process in Meiosis that contributes to genetic diversity?


What stage does this process occur in? Describe/draw the process

Answers

Explanation:

called crossing over or recombination. This process occurs during the first stage of meiosis (Prophase I) and involves the exchange of genetic material between homologous chromosomes.

During crossing over, homologous chromosomes pair up and form a structure called a bivalent. Within the bivalent, the chromatids of each homologous chromosome come into contact and exchange segments of genetic material. This exchange results in the formation of chromosomes that are a combination of genetic material from both parents, contributing to genetic diversity.

To better understand the process of crossing over, you can visualize it as follows:

Homologous chromosomes pair up to form a bivalent.

The chromatids of each homologous chromosome come into contact and form structures called chiasmata.

The chiasmata allow for the exchange of segments of genetic material between the chromatids.

The chromatids separate, and each resulting chromosome contains a combination of genetic material from both parents.

Crossing over is a crucial process in meiosis as it allows for the creation of genetically diverse gametes, which are important for sexual reproduction and evolution.

Because snapdragons (Antirrhinum) possess the pigment anthocyanin, they have reddish purple petals. Two pure anthocyaninless lines of Antirrhinum were developed, one in California the other in the Netherlands. They looked identical in having no red pigment at all, manifested as white (albino) flowers. However, when petals from the two lines were ground up together in buffer in the same test tube, the solution, which appeared colourless at first soon turned red. As a control for this experiment the petals from each of the two white flowered plant lines were ground up separately and tested separately in buffer. For these controls, the result was the same in both test tubes – colourless! A positive control using petals from a red flowered plant was also carried out and the solution in the test tube was red as expected. (a) What could account for the production of the red colour in the test tube when petals from the two plants were combined? . (b) What hypothesis about genes would explain this observation? . (c) Suggest genotypes for the two white flowered plants that fit with the observations. . (d) If the two white lines from California and the Netherlands were crossed, what would you predict the phenotype(s) of the F1 and F2 to be?

Answers

a) When petals from the two white flowered plants were ground up and combined in the same test tube, the solution turned red because the petals from the two plants contained alleles of the anthocyanin pigment.


b) This observation suggests that the two white flowered plants contain alleles of the anthocyanin pigment, one allele is dominant and the other is recessive.

c) The genotypes of the two white flowered plants are likely to be AA (homozygous recessive) and Aa (heterozygous) respectively.

d) If the two white lines from California and the Netherlands were crossed, the phenotype of the F1 would be red as the dominant allele would be expressed, and the F2 would have a ratio of three red to one white flower as the recessive allele is also present in the genotype.

a) Anthocyanin is a pigment which is produced by the synthesis of enzymes encoded by specific genes.

When the petals from the two white flowered plants were combined, the enzymes from both plants interacted and produced the pigmented compound anthocyanin, causing the solution to turn red.

b) This observation suggests that both plants possess the genes encoding the enzymes necessary for the synthesis of anthocyanin, but that the expression of those genes is inhibited in both plants.

This suggests that there is a gene or genes involved in the inhibition of anthocyanin production.

c) The genotypes of the two white flowered plants could be homozygous recessive for the gene/s that inhibit anthocyanin production. For example, they could be genotyped as aa.

d) If the two white lines from California and the Netherlands were crossed, the F1 offspring would be heterozygous for the gene/s that inhibit anthocyanin production, with a genotype of Aa.

Please provide an answer to the hundrenths decimal place (example. -21.32), and use of the appropriate sign (+ or -) is paramount. Units will not be counted, however you should know that the units are mV (millivolts).

Answers

The resting membrane potential of a neuron in a mammal can be calculated using the Goldman Equation. In this case, the cell is 10 times more permeable to Na+ than K+, meaning that the Na+ concentration is higher inside the cell than outside.

Using the given concentrations, the Goldman Equation can be used to calculate the resting membrane potential: Vm = 61 ∗ log10(PK[K+]o+PNa[Na+]oPK[K+]i+PNa[Na+]i) = 61 ∗ log10(3+150/145+10) = -21.29 mV.

This answer indicates that the resting membrane potential of the neuron is negative and is more negative than the equilibrium potential for K+ (approximately -90 mV). This is due to the high concentration of Na+ inside the cell, which creates an inward electrochemical gradient across the membrane, leading to a negative membrane potential.

The mean score of all test takers for the Quantitative Reasoning section was 153 with a standard deviation of 8.09. Suppose that the distributions of both section scores are approximately normal. What is the probability that a randomly selected GRE participant would have a Verbal Reasoning score between 135 and 145?

Answers

The probability that a randomly selected GRE participant would have a Verbal Reasoning score between 135 and 145 is approximately 0.2129, or 21.29%.

To find the probability that a randomly selected GRE participant would have a Verbal Reasoning score between 135 and 145, we need to use the z-score formula:

z = (x - μ) / σ

Where x is the score, μ is the mean, and σ is the standard deviation.
First, we will find the z-score for a score of 135:

z = (135 - 151) / 8.66
z = -1.85

Next, we will find the z-score for a score of 145:

z = (145 - 151) / 8.66
z = -0.69

Now, we will use a z-table to find the probability that a randomly selected GRE participant would have a Verbal Reasoning score between these two z-scores. The probability that a randomly selected GRE participant would have a Verbal Reasoning score less than -1.85 is 0.0322, and the probability that a randomly selected GRE participant would have a Verbal Reasoning score less than -0.69 is 0.2451.

Therefore, the probability that a randomly selected GRE participant would have a Verbal Reasoning score between 135 and 145 is:

Create a hypothesis that would mechanistically explain antigenic shift and how antigenic shift could possibly create a "hybrid" H5N1 Influenza virus that would be highly infectious, and highly lethal, for humans.

Answers

Hypothesis: Antigenic drift is the result of small mutations in the virus's genome, which can lead to changes in the amino acid sequence of the proteins on the surface of the virus. These changes cause the virus to become unrecognizable to the immune system, allowing the virus to evade the immune response and infect new individuals.

What is viral antigenic drift?

Influenza virus antigenic drift is the consequence of the virus's natural mutation rate, which results in minor genetic alterations, generally in the HA gene. Antigenic drift occurs when minor genetic modifications lead to minor differences in the antigenic structure of the virus. These minor variations enable the virus to evade immunity elicited by earlier exposures, resulting in repeated yearly outbreaks of influenza. Antigenic drift is a natural evolutionary process that occurs when the virus is subjected to selective pressure from the host's immune system over time.

However, the genome of the influenza virus is segmented, and the individual gene segments can undergo reassortment.The influenza virus's genome is made up of eight segments, and these segments are prone to reassortment, resulting in new combinations of genes. However, this reassortment event can only occur if two different influenza virus strains infect the same host cell at the same time, allowing for a "hybrid" virus to be formed with gene segments from both parent viruses.

1. What is the structure of a
bacterial mRNA transcript? Name each of the structure
elements and describe their function.
2. In eukaryotic cells, is there a 1:1
ratio of genes to gene products?

Answers

1. A bacterial mRNA transcript consists of a 5' untranslated region, coding region, 3' untranslated region, Shine-Dalgarno sequence, and a polyadenylation signal.

2. In eukaryotic cells, there is not always a 1:1 ratio of genes to gene products.

1. The structure of a bacterial mRNA transcript consists of the following elements:
- 5' untranslated region (5' UTR): This region is located at the 5' end of the mRNA transcript and is important for the regulation of translation.
- Coding region: This region contains the codons that specify the amino acid sequence of the protein that will be produced.
- 3' untranslated region (3' UTR): This region is located at the 3' end of the mRNA transcript and is important for the regulation of mRNA stability and translation.
- Shine-Dalgarno sequence: This sequence is located in the 5' UTR and is important for the initiation of translation in bacterial cells.
- Polyadenylation signal: This signal is located in the 3' UTR and is important for the addition of a poly(A) tail to the mRNA transcript, which helps to stabilize the mRNA and promote translation.

2. In eukaryotic cells, there is not always a 1:1 ratio of genes to gene products. This is because eukaryotic genes can undergo alternative splicing, which allows for the production of multiple different mRNA transcripts and protein products from a single gene. Additionally, some eukaryotic genes can produce non-coding RNA products, such as microRNAs, which do not encode proteins.

What are the four levels of eukaryotic gene regulation? Provide a
one sentence definition for each level of gene regulation.

Answers

Eukaryotic gene regulation involves four levels: transcriptional, post-transcriptional, translational, and post-translational. Transcriptional regulation is the process of determining which genes are expressed from the DNA; post-transcriptional regulation is the process of changing mRNA before it is translated; translational regulation is the process of changing the proteins produced from mRNA; and post-translational regulation is the process of modifying proteins after they are made.

Transcriptional regulation refers to the control of gene expression at the level of transcription, which determines when and how much of a particular gene is transcribed.
Post-transcriptional regulation refers to the control of gene expression after transcription has occurred, including the processing of RNA molecules and their transport to the cytoplasm.
Translational regulation refers to the control of gene expression at the level of translation, which determines when and how much of a particular protein is produced from a given mRNA molecule.
Post-translational regulation refers to the control of gene expression after a protein has been produced, including modifications to the protein that affect its activity or stability.

Calculations of average osmotic pressure. Attach a copy of the figure to this assignment. (7 marks)
Explain what factors determine the variability of the plasmolytic state of the Elodea
tissue/cells. (2 marks)

Answers

The Overton's Plasmolytic Method is a technique used to study the permeability of cell membranes.

In this method, a plant cell, such as an Elodea cell, is placed in a sucrose solution of a known concentration and observed over time. The changes in the cell are used to determine the permeability of the cell membrane to sucrose.

In the case of the Elodea cell placed in a 0.8M sucrose solution, it can be observed that the cell undergoes plasmolysis. This is a process in which the cell membrane pulls away from the cell wall as a result of water loss due to osmosis.

The sucrose solution is hypertonic to the cell, meaning that it has a higher concentration of solutes than the cell. As a result, water moves out of the cell and into the solution, causing the cell to shrink and the cell membrane to pull away from the cell wall.

The permeability of the cell membrane to sucrose can be determined by calculating the average osmotic pressure of the solution. This can be done by measuring the change in volume of the cell over time and using the equation for osmotic pressure:

Π = iCRT

Where Π is the osmotic pressure, i is the van't Hoff factor, C is the molar concentration of the solute, R is the gas constant, and T is the temperature in Kelvin.

The variability of the plasmolytic state of the Elodea tissue/cells can be determined by several factors, including the concentration of the sucrose solution, the temperature of the solution, and the presence of other solutes in the solution.

These factors can affect the rate of osmosis and the permeability of the cell membrane, leading to differences in the plasmolytic state of the cells.

Discuss the following class of reaction that happens inside a
cell with the help of an example: Class-I, Class-II, Class-III

Answers

Class-I reactions are those that involve the transfer of electrons from one molecule to another.

An example of this type of reaction is the reduction of oxygen to water during cellular respiration.

Class-II reactions are those that involve the transfer of functional groups from one molecule to another. An example of this type of reaction is the transfer of a phosphate group from ATP to another molecule during energy metabolism.

Class-III reactions are those that involve the breaking or formation of covalent bonds. An example of this type of reaction is the formation of peptide bonds between amino acids during protein synthesis.

In conclusion, class-I reactions involve the transfer of electrons, class-II reactions involve the transfer of functional groups, and class-III reactions involve the breaking or formation of covalent bonds.

Each of these classes of reactions plays an important role in the biochemical processes that occur within cells.

Take one H from each NH3, one O and two rods from the CO2 model.
Combine them to make H2O.

Answers

Yes, you can make H₂O by taking one H from each NH₃, one O and two rods from the CO₂ model.

To do this, take one of the H atoms from one of the NH₃ molecules. Then, take the oxygen atom from the CO₂ molecule, as well as two of the rods. Finally, combine the hydrogen and oxygen atoms together, which will form a water molecule.

To explain this process in more detail, we first need to understand what each of these molecules is composed of. NH₃ is composed of one nitrogen atom, three hydrogen atoms, and a lone electron.

The CO₂ molecule is composed of one carbon atom and two oxygen atoms, connected by two rods. To make H₂O, take one hydrogen atom from each NH₃ molecule and one oxygen atom from the CO₂ molecule, along with two of the rods.

When these atoms are combined, they form a water molecule, which is composed of two hydrogen atoms and one oxygen atom. This process is used in a variety of different industries and is a common part of everyday chemistry.
