In eastern gray squirrels, Sciurus carolinensis, the allele for black fur (B) is dominant to the allele for gray fur (b) . In a particular population of gray squirrels, 64% have black fur and 36% have gray fur. A researcher calculated the allelic frequencies to be B = 0.6 and b = 0.4. Which of the following could best explain the increase in the frequency of the Ballele in the population after five years?
a. The frequency of the B allele increased because it is the dominant allele.
b. The frequency of the Ballele increased because squirrels with gray fur exhibited greater fitness.
c. The frequency of the B allele increased due to the selective pressures of the environment.
d. The frequency of the Ballele increased because black squirrels randomly mate with other eastern gray squirrels.
Answer:
The answer to the given question is C.
Explanation:
Natural selection:
The population contains both superior as well as inferior organisms where natural resources are limiting so it will cause competition between organisms. As a result of competition, it will select superiors, and inferiors are deleted and they are given reproductive advantages. Due to this reproductive advantage new population emerges. It is more suitable for the environment.
Natural selection divides into three parts that are directional, disruptive, and stabilizing selection.
This is an example of natural selection. Environmental conditions create pressure on the individuals and if they can survive and become fittest, their number increases in the population. This is according to Darwin's theory in the struggle for existence. These organisms survived as the fittest organisms to match climatic conditions.
Stabilizing selection: This operates when features coincide with the optimal environmental conditions and the organisms survive in a population. Stabilizing selection pressures do not promote evolutionary change but tend to maintain stability within the population from generation to generation.
In the beginning, directional selection - the organism develops characters to survive in response to gradual changes in the environmental conditions. It works on a range of phenotypes existing within a population and exerts selection pressure which moves the mean phenotype to one phenotypic extreme. When the mean phenotype overlaps with the new optimum environmental conditions, stabilizing selection will take over.

B. Inversion and dorsiflexion of the foot is achieved by contracting the _________muscle.
C. The _________ muscle has a skeletal attachment on the distal phalanx of the first digit.
D. The___________ of the tibia is a skeletal attachment site of the tibialis anterior muscle.
Answer:
A. The d. extensor retinacula are the broad ligamentous sheets that contain the tendons of the anterior compartment muscles.
B. Inversion and dorsiflexion of the foot is achieved by contracting the a. tibialis anterior muscle.
C. The b. extensor hallucis longus muscle has a skeletal attachment on the distal phalanx of the first digit.
D. The c. lateral condyle of the tibia is a skeletal attachment site of the tibialis anterior muscle.
Explanation:
The two extra options are the f. extensor digitorum longus and the e. medial epicondyle. The first one is a muscle in the anterior part of the legs that originates in the anterior lateral condyle of the tibia and the anterior part of the fibula. Its insertion is in the four phalanges of the 2, 3, 4, and 5 digits. The first digit has the insertion of the extensor hallucis longus. The extensor digitorum longus and the b. extensor hallucis longus has the same function, the extension of the toes, the extensor hallucis longus only extends the first digit, and the extensor digitorum longus extends the other four digits simultaneously.
The second extra option, the medial epicondyle, is in the femur. It is a prominence in the distal part of this bone. The tibial collateral ligament and the Magnus muscle insert in this part of the femur.

Given the following cross TtYyRr x TtyyRr (T = tall; t = short Y = yellow; y = green R = round; r = wrinkled), what proportion of offspring would be expected to be short plants with round, green seeds. Write your answer as a reduced fraction - e.g. 1/2 proportion is
Answer:
3/32 ttyyR-
Explanation:
Cross: Tall, Yellow, Rounded individuals with a tall, green, rounded individual
Parentals) TtYyRr x TtyyRr
Gametes) TYR, TyR, TYr, Tyr, tYR, tyR, tYr, tyr (Parent one)
TyR, TyR, Tyr, Tyr, tyR, tyR, tyr, tyr (Parent two)
We need to know what proportion of offspring is expected to be short plants with round, green seeds. So we need to identify the gametes for these traits. The genotypes are:
Shot → ttRound → RR or RrGreen → yy⇒ Parent one can provide gametes tyR and tyr
⇒ Parent two can provide gametes tyR and tyr
(1/8 tyR x 2/8 tyR) + (1/8 tyR x 2/8 tyr) + (1/8 tyr x 2/8 tyR) =
2/64 ttyyRR + 2/64 ttyyRr + 2/64 ttyyRr =
1/32 ttyyRR + 2/32 ttyyRr =
3/32 ttyyR-
The branch of science which deals with the gene and inheritance is called biology.
The correct answer is 3/32.
When a parent has 3 characters and crosses with other parents which have a 3 character is called a trihybrid cross.
In this question, the genotype of the parent is given as follows:-
Mother - TtYyRrFather - TtyyRrThe gametes formed by the parents is as follows:-
TYR, TYr, TyR, Tyr, tYR, tYr, tyR, tyr is gamete of motherTYR, TYr, TyR, Tyr, tYR, tYr, tyR, tyr is gamete of father.According to the law of inheritance it stated that the each gamete can fused with any gamete to increase the chances of variation.
Hence, after the crossing the number of offspring will form is 32.
Therefore the offspring which has a short plant with a round green seed is 3/32.
Hence, the correct answer is 3/32.

What assumption regarding the population is necessary for making an interval estimate for the population mean?
Answer:
The assumption regarding the population which is necessary for making an interval estimate for the population mean is that:
a. We assume that the population has a normal distribution.
b. We assume that the central limit theorem applies.
Explanation:
The assumption regarding the population which is necessary for making an interval estimate for the population mean is that:
a. We assume that the population has a normal distribution.
b. We assume that the central limit theorem applies.
A normal distribution describes how the values of a variable are distributed. It is a probability distribution that is symmetrical about the central value or the mean, i.e. 50% of data are found to the left and right of the mean respectively. Most of the data are clustered around the mean, i.e. they occur or are found near the mean than far away from the mean. The graph form of a normal distribution will appear as a bell curve. In a normal distribution, mean = mode = median.
The Central Limit Theorem states that irrespective of the underlying distribution of a sample, when a variable does not follow a normal distribution, repeated random samples from the population will give sample means they are normally distributed. This means that the sampling distribution of the sample means approaches a normal distribution as the sample size gets larger.
In Wakanda, in a population in Hardy-Weinberg equilibrium, the frequency of the single recessive allele controlling vibranium assimilation, which affects superhuman abilities, is 0.2. What is the percentage of the population that is heterozygous for this allele
Answer:
32%
Explanation:
Hardy–Weinberg equilibrium is also known as Hardy–Weinberg law. The idea of Hardy–Weinberg equilibrium is about the frequency of alleles in a population. The frequency of an allele in the population will always remain the same in a population if that population is not influenced by any evolutionary consequences.
Hardy–Weinberg equilibrium binomial expression formula is p2+2pq+q2=1. Suppose the frequency of recessive allele = q.
and another normal allele is = p
Here Q = 0.2 so P will be 1- Q or 0.8
By Hardy–Weinberg equation p2+2pq+q2=1, Here 2pq denotes the frequency of recessive allele, so 2pq = 2 × 0.2 × 0.8 = 0.32, if converted into percentage it will be 32%.

An organism has the following characteristics: cell wall, heterotrophic, unicellular, and prokaryote. What kingdom does
it belong in?
• Animalia
• Protista
• Plantae
•Eubacteria
Answer:
The correct answer is - Eubacteria.
Explanation:
Eubacteria is a kingdom that comes under prokaryotic organisms. These organisms have many characteristic features that are as follows:
Body Structure: Eubacteria are single-celled organisms with a cell wall outside of the cell to protect them.
Food: Eubacteria are both auto- and heterotrophic which means they can be either autotrophic, they use both chemical synthesis and photosynthesis.
Animals lack the cell wall, planate are autotrophic and protists are eukaryotic organisms so the correct answer is eubacteria.
