What is rcbL, and why is it a particularly useful molecule for studying evolutionary relationships in plants and green algae

Answers

Answer 1

Answer:

RBCL denotes for 'rubisco protein.' It is characterized as 'a plant enzyme which catalyzes both the fixing of carbon dioxide found in atmosphere during photosynthesis and the reverse process of photorespiration.' It plays a very significant role in studying, as well as, in evaluating relations associated with phylogenetics in plants primarily along with green algae as it assists them to produce energy molecules by using carbon dioxide from the atmosphere. It has therefore been the key factor behind a number of organic carbon that is discovered in our surrounding biosphere.

The predominant forms of actin inside a cell are ATP-G-actin and ADP-F actin. What would be the consequence for actin filament assembly/disassembly if a mutation prevented actin's ability to bind ATP

Answers

Answer:

If actin is unable to bind to the ATP molecule, it will not be able to assemble into its two dominant forms.

Explanation:

As shown in the question above, the two predominant forms of actin are ATP-G-actin and ADP-F actin. As we can see, the formation of these two molecules involves the presence of an ATP molecule, in which case, the concentration of actin inside an organism depends totally on the capacity of the actin to be able to bind to an ATP molecule. If there is a mutation that prevents this binding from occurring, actin will not be able to form its two dominant forms, which will harm the presence of actin in the body.

What is the ethical dilemma associated with randomized controlled studies for suspected causes of disease such as cigarette smoking?

a. The prevalence of disease within the study cannot be controlled.
b. The effect of the disease is too detrimental to the health of those involved within the study to allow them to be voluntarily exposed to a suspected cause of disease.
c. Incidence of disease is often determined to be too low to conduct a randomized controlled trial.
d. It is difficult to establish definitive contributory cause even with a high-quality randomized controlled trial.

Answers

Answer:

b. The effect of the disease is too detrimental to the health of those involved within the study to allow them to be voluntarily exposed to a suspected cause of disease.

Explanation:

Randomized controlled studies assess the relationship between cause and effect. There are usually two groups in this study. The first group is the experimental group which is exposed to the treatment or intervention to be assessed while the second group is the control group which is given no treatment or given a placebo.

As it relates to the question, the experimental group is exposed to cigarettes to determine the effect of this exposure. This can have an adverse health effect on the experimental group, hence, this is an ethical dilemma.

Explanation:

A membrane consisting only of phospholipids undergoes a sharp transition from the crystalline form to the fluid form as it is heated. What would be the effect on this transition in a membrane containing 80% phospholipid and 20% cholesterol

Answers

Answer:

Having 20% cholesterol in a membrane would reduce the fluidity.

Explanation:

At high temperatures, cholesterol stabilizes the membrane and increases the melting point.

The plasma membrane is the layer that surrounds the cell and is composed of cholesterol and phospholipid. The presence of cholesterol reduces the fluidity and transition.

What are the components of the plasma membrane?

The plasma membrane separates the exterior and the interior of the cell and through a semi-permeable nature allows the transport of the molecules. It is composed of phospholipids and cholesterol molecules.

The phase transition of the membrane is known by the change in the rigidity as it starts free-flowing at a high temperature called transition temperature.

In the presence of cholesterol, the movement and the fluidity reduce as it interferes with the fatty acid chain and now requires more temperature to convert the rigid structure to become fluid.

Therefore, membrane-containing cholesterol requires more temperature to modify the fluidity as compared to phospholipids alone.

(h) Microfilaments, intermediate filaments, microtubules

(i) Microtubules, microfilaments

(j) Microtubules

Explanation:

Microtubules (MTs) are dimers of the protein tubulin (alpha- and beta-tubulin subunits) and they are major components of the cytoskeleton. MTs play diverse cellular roles including, mechanical support (cytoskeleton), transport, motility, chromosome segregation, etc. Microfilaments (MFs) are protein filaments that also form part of the cytoskeleton in eukaryotic cells. MFs consist of G-actin monomers assembled in linear actin polymers, and their functions include mechanical support, cytokinesis, changes in cell shape, amoeboid movement, endocytosis and exocytosis, etc. MFs associate with the protein myosin to generate muscle contractions. Actin filaments/MTs assembly from monomeric actin/tubulin is caused due to energy expenditure, where ATP/GTP bound to actin/tubulin is hydrolyzed during polymerization. Finally, intermediate filaments (IFs) are a type of cytoskeletal element composed of a heterogeneous group of structural elements, and they are not found in all eukaryotes. The primary function of the IFs is to contribute to the mechanical support for the plasma membrane where these filaments come into contact with other cells and/or with the extracellular matrix. The IFs are not directly involved in cell movement. All 3 types of cytoskeletal elements (microfilaments, intermediate filaments, microtubules) can be visualized by fluorescence microscopy when cells express chimeric MT/IF/MF.–GFP fusion proteins.

Elizabeth was a "granola mom"it was only natural and organic foods and therapies for her
family. She belonged to a food co-op and ordered special foods and home remedies through
the group
Elizabeth was well read and conscientious, and she had a remedy for everything
Little white pills that dissolved under the tongue treated everything from teething to bruising.
When her 8-year-old daughter Samantha had a sore throat, Elizabeth had her gargle with
colloidal silver remedy used before all the new and "dangerous" antibiotics. Samantha did
get over her sore throat, but three weeks later, she broke out in a rash, complained that her
points hurt, and had swollen glands. This worried Elizabeth, and so she consulted a
conventional medical doctor.
Samantha was diagnosed with rheumatic fever, and the doctor prescribed antibiotic treatment.
Elizabeth had read that antibiotics could damage the immune system, and was reluctant to
give them to her daughter
How can you as a nurse, encourage compliance with long-term antibiotie treatment without
abenating Elizabeth? To what extent does a parent have the night to refuse medical advice for
a child? When are alternative therapies helpful?

Answers

Answer and Explanation:

1. As nurses, we can inform you that the use of antibiotics according to medical advice is not dangerous, because the doctor is able to prescribe a correct dose, which must be taken at the correct time intervals, to fight the disease without damaging the immune system . In that case, if the girl takes the medicine exactly as the doctor prescribed, she will have no problems and her body will recover completely.

2. Parents only have the right to refuse medical advice, when such advice is clearly abusive, puts the child at proven risk, or presents experimental treatments without scientific evidence, as it may endanger the child.

3. Alternative therapies are beneficial when they are accompanied by traditional medical treatment, or when they seek to promote relaxation and stress reduction, without trying to fight infections and more serious health problems.

C is different in all organisms, except in monozygotic twins
D. the sequence of codons is not separated by intervals, but is continuous
E. the structure of the genes is constantly mutating

Answers

Answer:

B. an amino acid can be encoded by several codons

Explanation:

The genetic code refers to the set of rules that govern how the four nitrogenous bases (A,U,G,C) is arranged to form amino acids. The genetic code is a collection of all the CODONS formed. There are different characteristics of the genetic code and one of them is its REDUNDANCY.

Since there are 4 nitrogenous bases combined in three's to form a codon i.e. 4³, there are 64 possible codons that could form 20 maximum amino acids. This means that there are more codons in relation to amino acids. Hence, more than one codon can encode an amino acid, and this is referred to as REDUNDANCY of the genetic code.

For example, LEUCINE amino acid is encoded by 6 codons as follows: UUA, UUG, CUU, CUC, CUA, CUG.

If all 15 presynaptic neurons stimulate the post-synaptic neuron at the same time, will an action potential be produced?

Answers

Answer:

Yes

Explanation:

If all 15 presynaptic neurons stimulate the post-synaptic neuron at the same time, the action potential will be produced. In a chemical synapse, an action potential in the presynaptic neuron is responsible for the release of a chemical messenger known as neurotransmitter. After this, the neurotransmitter diffuses across the synapse and binds to the postsynaptic cell so we can say that potential can be produced.

How does penicillin kill bacteria? Penicillin augments the body's natural ability to enzymatically degrade bacterial peptidoglycan, causing the cells to lyse Penicillin targets a cross-linking reaction in cell wall manufacture. By blocking the enzyme responsible, penicillin stops the bacteria from producing new peptidoglycan. Penicillin targets muramic acid in the cell wall. By damaging a key component of the cross-linking reaction, the cell can't build a strong peptidoglycan mesh and quickly breaks apart. Penicillin damages the lipid membrane of bacterial cells by enzymatically removing peptidoglycan from the membrane's outer surface. The weakened cells quickly lyse.

Answers

Answer:

The correct answer is option c. By blocking the enzyme responsible, penicillin stops the bacteria from producing new peptidoglycan.

Explanation:

Penicillins are derived from Penicillium molds. These are a group of antibiotics, used in treating various types of bacterial infections such as urinary tract infections, respiratory tract infections, gastrointestinal infections etc.

These antibiotics also used in treating gonorrhoea, meningitis, pneumonia, syphilis, etc. These antibiotics stop the bacteria from producing new peptidoglycan that blocks the enzyme.

Answer:

10%

Explanation:

The parental crossings = Cd/Cd   x  cD /cD

The distance the genes C and D = 20 map units

Determine the percentage of  cd / cd recombinants that will be formed

the distance shows that there is only 20% recombinant progeny

The recombinants are : CD/CD and cd/cd = 20%

i.e. each recombinant progeny = 20% / 2 = 10%

The compound action potential increases in amplitude with an increase in stimulation voltage is due to recruitment of small diameter axons followed by large diameter axons in the nerve.

what is axons?

The part of a nerve cell (neuron) that transports nerve impulses away from the cell body is known as an axon. A neuron has one axon that connects it to other neurons, muscle cells, and gland cells.

What is compound action potential?

Compound action potential measurement capabilities are built into cochlear implants and are used as objective measures during device setup and programming. Because the stimulus recruits many fibers simultaneously and synchronously, the response is called a compound action potential because it is the sum of the many potentials recruited.

The amplitude of the reaction is increased via summation and synchronous production, making detection possible. A variety of diagnostic methods include recording the electrical activity of peripheral nerve neurons. A second deflection will emerge in the displayed waveform when we gradually increase the stimulus voltage using the control knob on the stimulator.
