According to the research, the correct option is A, population genetics is the study of how allele frequencies in a population change over time.
What is population genetics?It studies the origin, amount and distribution of genetic variability present in populations.
It explains the variation between individuals, as well as the dynamics of alleles and genotypes within and between populations.
Therefore, we can conclude that according to the research, the correct option is A, population genetics is the study of how allele frequencies in a population change over time.

explain in steps how a tree trunk gets wider
Answer:
The first thing that determines the thickness of a tree trunk is the species. Some kinds of trees just naturally have a different trunk thickness than others.
The second thing might be the environment. A tree that is experiencing all factors - sun, water, soil, minerals - at an optimum level is going to grow faster, taller, stronger, and thicker than the same species in a less-optimum environment.
A third factor is time. As time passes, the tree trunk increases in diameter - thus a tree that is 50 years old will have a much thicker trunk than one that is 5 year old.
And, in case you’re wondering why or how tree trunks increase in thickness at all, there is a thin layer of cells all around the trunk of a tree, like a sheet that lives under the bark. This layer is called the cambium layer which makes new living tissue for the tree (called phloem and xylem) every year. As the year’s growth comes to an end, the living tissue dies and is pushed outward to appear as bark by the new year’s sheet of cambium cells, which is bigger than the previous year’s - hence, the increase in diameter of the tree every year.
A sample of the element boron will have some atoms with six neutrons and some atoms with five neutrons; collectively, these atoms are called
OA. cations.
OB. anions.
OC. isotopes
OD. ions
Answer: OC. Isotopes
Explanation: Isotopes of element are those who have same numbr of protons but different number of neutrons. Here number of neutrons are different so these atoms are isotopes.

Codons are triplets of nucleotides found on mRNA which code for particular amino acids .
What are codons?Codons are triplets of nucleotides found on mRNA which code for particular amino acids.
In an mRNA, strands, the first three codons, AUG code for the amino acid methionine.
Similarly, the codons GCA codes for alanine, CCA codes for proline.
In conclusion, given an mRNA strand, the amino acids coded by the codons can be deduced.

A water-soluble hormone approaches its target cell. What can we conclude about this hormone?
The hormone originated in the ovaries or testes
The hormone will be a non-steroid
The hormone is hydrophobic and will need to combine with protein molecules to enter the cell
The hormone released will signal the beginning of puberty
If a water-soluble hormone approaches its target cell, it can be concluded that the hormone will be a non-steroid (option B).
What is an hormone?An hormone is any substance produced by one tissue and conveyed by the bloodstream to another to effect physiological activity.
Hormones are usually proteinous in nature and can either be water-soluble or fat-soluble depending on whether it can dissolve in water or fat respectively.
According to this question, a water-soluble hormone approaches its target cell. This suggests that that hormone must be a non-steroid i.e. does not contain fat.

Based on the Punnett square above, what is the probability that an offspring from this cross will have a completely heterozygous genotype for both traits ?
A. 50%
B. 25%
C. 12.5%
D. 6.25%
Answer:
A) 50%
Explanation:
Boxes 2 and 3 are heterozygous because solving the punnet square results in those boxes being Tt
In horses, gray horses (GG) are codominant to white
horses (WW). The heterozygous horses (GW) is an
Appaloosa horse (a white horse with gray spots on
the rump and loins). Cross a white horse with an
appaloosa horse. For the following, construct a
Punnett square and give the genotypic and
phenotypic ratios of the offspring. {Hint: The first
parent genotype needs to go down the left side of
the Punnet square, and the second parent
genotype needs to go across the top of the Punnett
square.
Genotypic ratio = 50% WW, 50% GW
Phenotypic ratios = 50% white, 50% appaloosa
Monohybrid crossWhite horse genotype = WW
Appaloosa genotype = GW
WW x GW
GW WW GW WW
Genotype ratio = 50% WW, 50% GW
Phenotype ratio = 50% white, 50% appaloosa
