Complete question:
Beak Length in Finches
In a certain population of finches, a single gene controls beak length. There are two possible alleles: S, which leads to a short beak, and s, which leads to a long beak. Individuals with the genotype SS will have a short beak, individuals with the genotype ss will have a long beak, and individuals with the genotype Ss will have a medium-length beak. Scientists measure that in this population of 1,128 total birds, 321 birds have short beaks, 562 have medium-length beaks, and 245 have long beaks.
Based on the original data collected from the population of 1,128 birds, what fraction of the population would be expected to have the SS genotype if the population was in Hardy-Weinberg equilibrium?

What is meant by the term "density"? Please provide an example of how
density is determined in air masses.
Answer:
1) density "the degree of compactness of a substance."
2) air masses "More dense, or “heavier” air will slow down objects moving through it more because the object has to, in effect, shove aside more or heavier molecules. Such air resistance is called “drag,” which increases with air density."

When does transformation occur
Answer:
Transformation results in the genetic alteration of the recipient cell. Exogenous DNA is taken up into the recipient cell from its surroundings through the cell membrane (s). Transformation occurs naturally in some species of bacteria, but it can also be affected by artificial means in other cells.

i. law of Independent Assortment
j. meiosis I
1. _____is illustrated by the behavior of two pairs of homologs during_____. The alignment of one homologous pair is_____the alignment of other pairs. 2. _____is illustrated in_____when homologs separate. Alternate alleles of a gene found on homologs segregate from each other and end up_____.
Answer:
1. law of Independent Assortment; metaphase I; independent of.
2. law of Segregation; meiosis I; in separate gametes.
Explanation:
Between 1856 and 1863, Gregor Mendel developed a series of mating experiments using pea plants, which enabled the discovery of some basic principles of inheritance. These principles/laws are stated as:
1) Law of segregation: this principle states that the inheritance pattern of phenotypic traits is characterized by the presence of a gene pair and each gamete carries only one allele for each gene pair so offspring inherit one gene variant (allele) from each parent
2) Law of independent assortment: this principle states that the genes responsible for the inheritance pattern of different traits are independently sorted from one another and thereby different traits are independent one from another.
3) Law of dominance: this principle states that the dominant allele will always be expressed in heterozygous individuals (this law is only applicable in cases of complete dominance).

In 1998 paleoanthropologist Rick Potts of the Smithsonian institution published an article in the yearbook of physical anthropology a peer reviewed Journal the article was titled environmental hypotheses of hominin evolution in his paper pots provided evidence to support his claim that gray variations and environmental conditions over time or responsible for the attacks ability of humans and the success of our species why might this not be the best article to reference?
Answer:
Because the author of the article did not do an experiment to draw his own conclusions and issue his own information, but he did a bibliographic review of the work of other authors to write his own article.
Explanation:
The article presented in the question above was done through a bibliography search and not through an experiment. This means that the author did not test the hypotheses through a scientific experiment, but formulated the conclusions of his article, based on the works of other authors, which makes this article not the best option to be considered as a reference article.
What is interkinesis??
Answer:
Interkinesis or interphase II is a period of rest that cells of some species enter during meiosis between meiosis I and meiosis II. No DNA replication occurs during interkinesis; however, replication does occur during the interphase I stage of meiosis.

Myoglobin transfers oxygen obtained from hemoglobin to mitochondrial proteins involved in the catabolism of metabolic fuels to produce energy for the muscle cell. What can you conclude about the structures of these mitochondrial proteins?
Answer:
Explanation:
Mitochondria is a double membrane bound organelle that is located in most eukaryotic organisms and it has a number of different shapes.
A mitochondrion has a outer and inner membranes made up of phospholipid bilayers and proteins which have different properties. Because of the double membraned organization, mitochondria have five distinct parts:
Outer mitochondrial membrane
Intermembrane space which is the space between the outer and inner membranes
Inner mitochondrial membrane,
the cristae space which is formed by the folding in of the inner membrane and
matrix which is the space within the inner membrane.
Mitochondria has a complex structure that allows for all the activities carried out by it this includes,Energy conversion, Pyruvate and the citric acid cycle, NADH and FADH2 which are the electron transport chain, Heat production and Storage of calcium.

Answer:
It greatly affect population of fish.
Explanation:
If there were no shrimp in the close ecosystem then many fishes die due to lack f food because shrimp is the food of many small and large fishes. They also play a great role in protection of fish's skin by eating parasite, bacteria and fungi present on their skin so it also act as scavengers so if these shrimps are not present many fishes die due to various diseases and the ecosystem would be disturb.

Knowing that some individuals from Island 1 colonized Island 2, biologists sample the Mainland and two Island populations fifty years after the colonization events. They determine that allele frequencies are similar on both islands, but they are significantly different than the frequencies of the mainland population. Which of the evolutionary mechanisms could be used to explain these observed
Answer:
The evolutionary mechanism that could be influencing the allele frequencies between both islands and the mainland population might be Founder Effect.
Explanation:
Genetic drift is the random change that occurs in the allelic frequency of a population through generations. The magnitude of this change is inversely related to the size of the original population. These changes produced by genetic drift accumulate in time and eventually, some alleles get lost, while some others might set. Genetic drift affects a population and reduces its size dramatically due to a disaster -bottleneck effect- or because of a population split -founder effect-. In founder effect, a new population originates when a few individuals who are coming from a bigger population carrying its genes, settle down in a new area and reproduce. This small population might or might not be genetically representative of the original one. Some rare alleles might be exceeded or might be completely lost. Consequently, when the small population increases in size, it will have a genetically different composition from the original one. In these situations, genetic variability is reduced and there exists the possibility of developing a peculiar allelic composition. If the number of individuals that originated the new population is low, the founder effect will be very extreme, because the effects of the genetic drift are inversely proportional to the original number of individuals.
In the exposed situation, the evolutionary mechanism that could be influencing the allele frequencies between both islands and the mainland population might be Founder Effect. The fact that both islands are similar in their frequencies might be due to little genetic variation on island 1, or because dispersion to island 2 is a recent event on time.
In poultry, two genes R and P, control the shape of the comb on the head.

Explanation:
i)Which one of the following substances have sour test.a) acid b)base c) salt d) all of these
Answer:
a) acid
Explanation:
Acid is a chemical substance that is capable of donating protons (H+) when in an aqueous solution. This property makes a substance an acid, although the ability to donate completely or partially distinguishes a strong and weak acid.
One of the characteristics of acids is their SOUR TASTE. This characteristic sour taste is attributed to the hydrogen concentrations present in acidic foods or substances e.g unripe fruits.
