According to sources, the most probable answer to this query is that meiosis is the cell division responsible for replicating gametes. These gametes are haploid rather than diploid cells.

Because they rely on their dense fur for insulation from the chilly ocean water, sea otters are particularly vulnerable to the detrimental effects of an oil spill. If a sea otter swims into an oil spill, its fur becomes soiled and loses its insulating qualities, allowing water to penetrate to its skin, causing hypothermia and ultimately, death.

Answer:
allelic frequency a = 30%
allelic frequency A = 70%
Explanation:
You are studying a population of sparrows in which the phenotype is determined by a single locus. Only two alleles for this locus are known for this population, which are distinguished by the codes 'A' and 'a'. The distribution of phenotypes in the population indicates that 49% of the population is homozygous 'AA', 42% is heterozygous and 9% 'aa' homozygous. How is the allele frequency for 'A' and 'a' determined based on these observations?
According to the case, the allelic frequency for A and a will be searched with the data:
homozygotes AA = 49%
heterozygotes Aa = 42%
homozygous aa = 9%
Frequency of homozygotes 'aa'
(q 2) = 9/100 = 0.09
we can obtain the allelic frequency of a through the following formula:
a (q) = √0.09
The result will be
= 0.3
we change to percentage
= 30%
we have the following formula
p + q = 1
to find the allele frequency A, represented by p
p = 1 - 0.3
we get the following result
p = 0.7
we change to percentage
= 70%
Mitochondria is the organelle which is involved in cellular respiration and that is linked to development. The primary function is to perform cellular respiration.
Mitrochondria which is also known as powerhouse of the cell Because 32 ATP are created from this organelles. It is produced energy in the form of ATP when cell respire.Oxygen and glucose both are the reactants in the process of cellular respiration.
The major product of cellular respiration is ATP which is waste products include carbon dioxide and water.Cellular respiration takes place in mitochondria, which are often called the cell's "powerhouses" because they make maximume no of a cell's ATP. Glycolysis splits glucose into two three-carbon molecules and makes two molecules of ATP.
