The proportion of dominating people in the following population is (1+4)%, or 5%.
The Hardy-Weinberg rule states that in the absence of evolutionary driving forces, allele and genotype frequencies in a population remain constant.
It claims that the binomial expansion of the square of the sum of p and q can be used to describe the total genotype frequencies.
The following sum equals one: (p+q) ²= p²+ 2pq + q².
In this instance, "p" represents the frequency of the dominant allele, and "q," that of the recessive allele. The expression "2pq" represents the population's frequency of heterozygotes.
The frequency of the dominant allele is given by p+q=1, while the frequency of the recessive allele is given by q = 0.9 for a certain hereditary trait. Consequently,
p=1-q
P=1-0.9 = 0.1
p²= (0.1) =0.01 or 1% of the population has a homozygous dominant genotype.
The percentage of heterozygous dominant genotypes in the population as a whole is 4% (PQ)² = 2 X 0.1 X 0.2 ".
∴ (1+4)%
=5%.

In some species of plants, mutations can cause a plant to have different patterns on their leaves, such as gold edges or whitestripes. Plants with different patterns grow to the same size and produce offspring with similar patterns. However, these plants canhave high mutation rates.

In eukaryotes, the components of citric acid cycling and the electron transport chain are located in the ____.
In eukaryotes, the citric acid cycle takes place in the mitochondrial matrix. Glycolysis occurs in the cytosol. Electron transport chain includes both the intermembrane space and the inner mitochondrial membrane.
Pyruvate from glycolysis is transported to mitochondrial matrix for the citric acid cycle to take place. The citric acid cycle is where acetyl CoA is modified in the mitochondria to produce energy precursors required for the next step.
The process where electron transport from the energy precursors from the citric acid cycle leads to the phosphorylation of ADP, producing ATP is Oxidative phosphorylation. The Electron transport chain is embedded within the extensive inner membrane of the mitochondrion close to the mitochondrial matrix in which the TCA cycle is localized .

b
Incomplete Dominance
c

Type of inheritance pattern that is best described below is Multiple Alleles.
Multiple alleles are the alternative forms of the same gene so they influence the same trait. The wild-type allele is mostly dominant over the mutant alleles.
Multiple alleles exist in a population when there are many variations of a gene present. In organisms with two copies of every gene, also known as diploid organisms, each organism has the ability to express two alleles at the same time. They can be the same allele, which is called a homozygous genotype. Multiple allelism, occurs when more than two gene forms exist for the same locus.

If I could make a change in West Virginia, the law will be in regards of arms possession by civilians.
Total Ban on arms possession by civilians in West Virginia.West Virginia is known to be a state that gives room for open carry without a permit. If a person is at least 18 years old and has a legal right to possess a handgun under state and federal law, they are permitted to carry a firearm openly without a license. There are some places that are off-limits, such courts and schools.
It is a society that recognizes the right to carry a concealed weapon within the state without first acquiring a concealed handgun license. This law may seems okay for some people, but its negative implications outweigh its advantages.
With the high rise in gun violence, there is therefore the need to amend this law. The Second Amendment does not protect concealed carry of arms, according to opponents of the practice, who also contend that police personnel with the appropriate training should be in charge of ensuring the protection of the public.
Therefore, i believe a total ban should me place on civilians carrying fire arms so as to protect the people from harm.

Alternative processing of an mRNA primary transcript may result in the formation mature mRNA
What is a primary transcript ?When an RNA transcript is first made in a eukaryotic cell, it is considered a pre-mRNA or primary transcript and must be processed into messenger RNA (mRNA).
The primary transcript is modified to form the mature mRNA. Primary RNA transcripts synthesized by RNA polymerase II (mRNA) are modified in the nucleus by three distinct reactions: addition of the 5' cap, addition of a poly-adenylic acid (poly-A) tail, and non-informative introns. Segment excision. During transcription of mRNA in eukaryotes, some sequences are excised from the primary transcript and the remaining sequences are joined. This processing of mRNA is called splicing. Alternative splicing of precursor mRNAs is an essential mechanism for increasing the complexity of gene expression and plays an important role in cell differentiation and organismal development.

The principle of proximity, a Gestalt concept, is used in this differentiation. According to this theory, items that are near together are seen as a group, whereas those that are far apart are seen as individual beings. In the case of a flock of birds, their proximity provides a sense of oneness and causes us to perceive them as a group while they are flying close together. Yet, their proximity is diminished at a great distance, and we see the birds as individual birds flying apart. One of the Gestalt concepts that aid in the organization and comprehension of visual data is the idea of closeness.

Explanation:
geneticists often assume that map distances less than 7 to 8 map units (m.u.) are accurate. map distances that exceed this threshold significantly are assumed to be less accurate and the level of accuracy declines as map distances increase. briefly explain this observation.
The further apart two genes are the more likely it is that multiple crossovers will occur.
Even if there has been crossing over, the offspring may still have parental genotypes that are not considered recombinants if there is a double crossover (or an even number of crossovers) between two genes. Double crossings will cause the real map distance to be underestimated since genetic maps are constructed by counting visible recombinants in the progeny.
The middle allele is transferred from one sister chromatid to the other during a double-crossover event, which is the following crucial step. As a result, the surrounding genes' parental alleles and the non-parental allele of the middle gene are positioned on the same chromosome.

Explanation:
A bacterium that is exposed to a toxin in its environment can make an enzyme to neutralize the toxin. The bacterium controls protein synthesis to produce the enzyme by activating an inducible operon. The activation of the operon causes the transcription of the mRNA that codes for the enzyme. The mRNA is then translated to make the specific enzyme needed to neutralize the toxin.

A
Evolution by natural selection
B
Cell differentiation by prokaryotes
C
Adaptation to external stimuli

The phenomenon that is demonstrated in this example is adaptation to external stimuli. That is option C.
What is adaptation?Adaptation is defined as the ability of an organism to adjust to its every changing environment in order to survive and reproduce.
From the example given in the question, the bacteria was exposed to a toxin in its environment but the bacteria was able to adapt through the production of an enzyme the neutralises the toxin.
