Answer:
it results in pleiotropic effect and caused death of an offspring.
In pea plants, flowers are either white or purple: the purple color is produced by pigments called anthocyanins. The production of anthocyanins is a two-step process: the first step is controlled by the C gene and the second by the P gene. Both genes must produce functional proteins for anthocyanin to be produced. This is an example of:
Answer:
This is an example of gene translation.
Explanation:
Gene translation refers to the genetic process where a set of genes is used to create amino acids that will be responsible for creating a protein needed to perform some function or characteristic of the organism. In the question above, we can see that anthocyanin, responsible for the pigment of flowers, is created through the work of proteins that are created from gebes C and P. This is an example of gene translation, as it presents the formation of proteins regulated by genes.
In these imprinted cells, the SNRPN transcript overlaps with another gene, called UBE3A, which is transcribed in the opposite direction. This means that the region that the RNA polymerase transcribes in these two genes actually overlaps; in some cases, overlapping transcription in opposite directions leads to transcriptional interference, meaning that collisions between the polymerases traveling in opposite directions can interfere with transcription. It is believed that this takes place in this case, meaning that the more SNRPN transcription occurs, the more this disrupts transcription of UBE3A. Based on this information as well as information about the effects of imprinting on SNRPN transcription, which of the following statements about UBE3A transcription would be true?
a. The maternal copy of UBE3A is expressed and the paternal copy is silenced.
b. The paternal copy of UBE3A is expressed and the maternal copy is silenced.
c. Both copies of UBE3A are highly expressed.
d. Both copies of UBE3A are silenced.
Answer:
a. The maternal copy of UBE3A is expressed and the paternal copy is silenced.
Explanation:
When UBE3A chromosome is in neurons, paternal allele is silent and maternal allele is expressed in process of genomic imprinting. In some cases UBE3A is expressed from both paternal and maternal chromosomes. The paternal chromosome is blue whereas maternal chromosome is magenta.
In the Science Olympiad, what is the main branch of science to study?
Answer:
Well, so far there are three branches of Science namely;
Earth SciencePhysical ScienceLife ScienceFurther studies of the genes in the region around the MHC locus identified C4 as a likely causative gene. A particular allele of C4 was significantly associated with schizophrenia. In addition, it was found that individuals with high expression of this allele of C4 had elevated risk of developing schizophrenia. Which of the following variants would be most likely to increase risk of schizophrenia from this allele?
a. a variant that decreases binding of an activating transcription factor to the C4 promoter
b. a 5’ UTR variant that destabilizes the C4 mRNA
c. a duplication of the C4 gene
d. a nonsense coding variant
Answer:
c. a duplication of the C4 gene
Explanation:
Schizophrenia is a disease that affects the brain, which is characterized by an imbalance of neurotransmitters and the presence of damaged brain tissues. In humans, the Complement component 4 (C4) protein is found at the neurons (i.e., cell bodies, dendrites and axons), which are the most common brain cells, and neuronal synapses. Moreover, gene duplication can increase gene expression when repressive mechanisms (e.g., DNA methylation at promoter sites) capable of silencing the expression of the duplicated gene are lacking. Recently, it has been discovered that a chromosome rearrangement associated with a tandem duplication of a genomic region that contains a C4 gene may contribute to schizophrenia risk by increasing the expression of this gene. In this example, a, b and d options are associated with a decrease in expression of the C4 gene, either by decreasing its transcription (options a and d) or by posttranscriptional mechanisms (option c).

Try this for yourself. Suppose you want to estimate the number of field mice in a small field. One day you capture 500 mice, mark all of them and release them. The next week you capture 200 mice of which 40 were marked by you yesterday. What is your estimate of the population size?
Answer:
The approximate size of the field mice population is 2500 individuals.
Explanation:
There are different methods to study population density. There are direct methods and indirect methods. Among these last ones, we might find the "Mark-Recapture technique".
The Mark-Recapture technique assumes that the population is closed, during the sampling season there is no mortality nor natality, marks in the individual last the whole sampling season, and these do not affect the marked individual or their behavior. These marked individuals are randomly distributed in the population, and all the individuals have the same probability of being sampled.
The method consists of capturing a sample of individuals belonging to the population under study, in this case, the field mice population. After capturing the individuals, the researcher marks them and release them again. The third step is to sample again, capture a new amount of individuals, and count how many of them are marked. These marked individuals belong to the first sample. We can calculate the population size by using the Lincoln Index or any other index.
The Lincolns Index states that to obtain the population size, the research must follow the following procedure:
1) Take an initial sample with n1 number of individuals
2) Mark all the sampled individuals and release them
3) Take a second sample with n2 number of individuals
4) Count the number of marked individuals m
To estimate the total number of individuals in this population, N, the following equation must be considered:
N = (n1 x n2)/m
In the exposed example, this is:
• n1= 500 individuals in the first sample
• n2= 200 individuals in the second sample
• m= 40 individuals in the second sample that were previously marked
as they were part of the first sample
N = (n1 x n2)/m = (500 x 200) / 40 = 2500 individuals
The approximate size of the field mice population is 2500 individuals.

the control group the independent variable the dependent variable the hypothesisAnswer:
2. the independent variable
Explanation:
During an experiment, data from an experimental group is compared with the data from a control group. Both groups are selected from the same pool or population, so they are identical in all aspects except for the independent variables.
The election of a control group is essential in an experiment. Its principal purpose is to allow the discrimination of the results obtained by the treatment in the study, from the results that might be a consequence of other factors. The control group does not receive any treatments. It is used to identify any other factors influencing the results obtained in the study, apart from the modified variables of the treatment.
The experimental group is the one that receives the experimental procedure or treatment. The researcher voluntarily changes the independent variables in the experimental group to observe how they affect the group under study. These variables are kept constant in the control group, not influencing the results, while the experimental group receives the treatment. There can be several experimental groups.
Independent (manipulated) variable: Refers to all the variables in an experiment that provoke a response in another variable. An independent variable is the one that changes or is controlled and modified in the experiment to analyze how another variable responds to it. It changes to analyze its effects on the dependent variable. Usually, the independent variable is represented by the X letter.
Dependent variable: Refers to the variable that depends and reacts to any change in the independent variable. It represents a quantity of something which value depends on how the independent variable is modified. This change might be proportional or inversely proportional to the change in the manipulated variable. It is usually identified by the letter Y.
The hypothesis is a conjecture. The researcher hypothesizes in order to predict what is going on or what is expected to occur. A hypothesis is a claim of how it works a relation between two or more variables. Usually, it is written in the present time.
----------------------------------------------------------------------------------------------------------
The proximity of the pond to agriculture might be considered as an independent variable.
The researcher chooses ponds according to their distance from the crops. In the exposed example, the researcher chose a pond is surrounded by high-density livestock areas and another one at least ten miles away.
The magnitude of run-off might depend on how far the pond is from the crops.
Discuss the sensory neurons for vision. What are the two
types of sensory neurons for vision? Where are they located?
What are their functions in the eye? What path does visual
input take AFTER reaching the sensory neurons (be specific,
outlining the entire path to the destination point of the brain)?
Answer:
Olfactory sensory neurons (OSN).
Explanation:
Olfactory sensory neurons (OSN) are the sensory neurons that is responsible for vision. Photoreceptors and olfactory sensory neurons (OSN) are the two types of sensory neurons for vision. Both olfactory sensory neurons (OSN) and photoreceptors is responsible for the receiving of photons and enable us to see things. The right half of the visual field will travel in the left optic tract, while on the other hand, the stimuli from the left half of the visual field will pass through the right optic tract.
Answer: The two types of sensory neurones are the CONES and RODS. Their functions are better outlined below
Explanation:
The CONES and RODS are the sensory neurones ( photoreceptors) of the eye which are located in the retina.
The RODS: They are extremely sensitive and can detect light of very low intensity. They also perceive light in black and white. They, therefore, play an important role in dim light.
The CONES: They function in bright light and are responsible for colour vision.
The path visual input take AFTER reaching the sensory neurons is as follows:
--> the rods and cones are stimulated
--> A pattern of electrical impulses is sent to the brain through the optic nerve which interprets it, drawing on past experience.
The brain tells us that the object is upright and gives us it's real size and distance from the eye. We, therefore, see the object as it actually is, and not as the image formed on the retina.

When body temperature increases, thermoreceptors are stimulated and send nerve signals to the CNS. The CNS sends motor signals to sweat glands, which attempt to reduce body temperature. This is an example of a __________ reflex.a. organ.b. stretch.c. withdrawal.d. visceral.
Answer:
d. visceral.
Explanation:
The visceral reflex is one that happens autonomously in the body, aiming to maintain the balance of the body through quick responses to some specific impulses. An example of a visceral reflex is the reduction in body temperature with the release of sweat from the sweat glands.
The visceral reflexes are controlled by the autonomic nervous system, using the sympathetic and parasympathetic nervous system.

Population - An individual life form. and Community - A group of populations.
What is population?A population is the entire set of people in a group, whether that group is a country or a collection of people who share a certain trait.
A population is the group of people from which a statistical sample is taken in statistics. Therefore, a population is any collection of people who have something in common.
A statistically significant portion of a population, rather than the full population, may also be referred to as a sample. For this reason, the standard deviation, or standard error, of a statistical study of a sample from the full population must be disclosed.
Therefore, Population - An individual life form. and Community - A group of populations.

A reproductive cell must differ from other normal body cells. The reproductive cell must ______________ because it will soon fuse with another reproductive cell to form a new individual
I'm not 100% sure what the exact answer is to this, because lots of things could be said about what gametes need to do for reproduction.
I suppose since it says that it's combining with another cell, it's hinting at the fact that reproductive cells are haploid.
If this is multiple choice I would choose the choice that has to do with gametes being haploid.
A reproductive cell must differ from other normal body. The reproductive cell must Haploid because it will soon fuse with another reproductive cell to form a new individual.
How is a reproductive cell specialized?The requires the union of two specialized cells, called gametes, each of which contains one set of chromosomes.

a. Contains an F' his+ trp
b. Has become F-
c. Contains an Hfr translocation
d. No longer mates as a merry diploid
e. Not enough information is given
Answer:
The correct answer is - b. has become F-.
Explanation:
In the case of the cross of two different strains, some genetic material moves to the F- strain from the Hfr strain, but due to genome size, it's not possible that all the genes can pass into a single bacterium.
Instead of complete transfer, each individual F- cell gets a different and random subset of genes from the Hfr. There is no translocation and F' does not contain his+ trp+.

Part D :
How might someone dispute the results of this investigation? How might you counter the argument?
Answer:
It could be argued that there is a separate force acting upon the investigation. Or that the room is invalidating the results for some reason. Or that an error was made in measurement.
There are a thousand and one ways to try to dispute an investigation like this. However, for every argument that can oppose it, a counterargument can easily be made.
For instance, controlling the variables invalidates about 90% of any possible claims to the contrary. The majority of arguments would stem from the fact that it is nearly impossible to completely prove something in fear of external factors. The solution? Control the external factors.
So, in conclusion, a person could dispute the results of the investigation by claiming that something invisible like magnetics could not possibly be proven to exist, because there are all sorts of things that could be influencing the investigation. The way to counter the argument would be to prove yourself that the environment is controlled, and that nothing could be influencing the investigation.

2. Mutations within a____may lead to major changes in______for example, ita Hox gene is attected. Moreover, if a transposable element inserts here, it may lead to a decreased or increased_____. This may impact the organism and if passed on to the offspring, become____. The result of these events may eventually lead to increased fitness and formation of new species.
Answer:
1. Mutations in protein-coding genes and regulatory DNA contribute to evolution if the organism carrying them survives and_c. reproduce. Mutations in a_a. gene lead to different effects. For example, a mutation may change the _h. function of the protein or the protein will no longer be produced.
2. Mutations within a_i. regulatory sequence may lead to major changes in_g. body form, for example, if a Hox gene is affected. Moreover, if a transposable element inserts here, it may lead to a decreased or increased_d. protein production. This may impact the organism and if passed on to the offspring, become_e. inherited. The result of these events may eventually lead to increased fitness and the formation of new species.
Explanation:
Mutations can be defined as genetic changes (nucleotide changes) in the genome sequence of an organism. Mutations can be beneficial, neutral or deleterious (depending on their effects on the adaptive fitness of the individual). Mutations that occur in the somatic (body cells) will not be inherited, whereas mutations in the germinal (gamete) cells can be passed on to the next generations. Moreover, Hox genes are major developmental regulators involved in a wide variety of aspects of animal development. In consequence, changes in the expression level of Hox genes caused, for example, through 1-mutations of their regulatory sequences, such as promoter sequences, or 2-the insertion of transposable elements, may lead to conspicuous phenotypic changes by affecting protein production. Eventually, these mutations may confer an adaptive advantage.
