The type of macromolecule that determines the traits a plant will inherit from its parent plants is DNA (deoxyribonucleic acid).

DNA is a large biological macromolecule composed of nucleotides that carry genetic information in the form of a code.

The DNA molecule contains the instructions necessary for a plant to develop and function. These instructions are passed down from parent plants to their offspring through the transmission of DNA during sexual reproduction. The specific sequence of nucleotides in the DNA molecule determines the expression of genes that code for various traits in the plant, such as height, flower color, and leaf shape.

Therefore, DNA is the biological macromolecule that ultimately determines the traits a plant will inherit from its parent plants.

Turgor pressure is the force that allows a plant to become more rigid and stand upright. Turgor pressure is the pressure exerted by water inside the plant's cells against the cell walls. The water enters the plant's cells through a process called osmosis, where water moves from an area of high concentration to an area of low concentration.

When the plant's cells are filled with water, they become swollen and exert pressure against the cell walls, which gives the plant its rigid structure. This turgor pressure is especially important for plants that grow upright, such as trees and flowers, as it helps them maintain their shape and resist external forces such as wind and rain.

Turgor pressure is also essential for plant growth and development. Without adequate turgor pressure, plants may wilt, and their growth may be stunted. Therefore, maintaining proper water balance and turgor pressure is critical for the health and survival of plants.

In gametes, there are either one (if the person is homozygous) or two keratin genes (if the individual is heterozygous).

The number of alleles for keratin in gametes depends on the genetic makeup of the individual. Keratin is a protein that is expressed in skin cells but not in white blood cells. It is encoded by a gene that is present in the genome of an individual, and each person inherits two copies of this gene (one from each parent).

These two copies, or alleles, may be identical or different, and they determine the individual's genetic information for keratin. If both alleles are the same, the individual is homozygous for that gene. If the alleles are different, the individual is heterozygous.

During meiosis, the process by which gametes are formed, the two alleles for each gene segregate, meaning that each gamete receives only one of the two alleles.

Therefore, the number of alleles for keratin in gametes is either one (if the individual is homozygous) or two (if the individual is heterozygous).

The process where the best adapted individuals in a population survive and reproduce to pass on their traits to their offspring is known as Natural Selection.

Natural selection is a mechanism of evolution in which organisms that are better adapted to their environment tend to survive and produce more offspring. The term "survival of the fittest" is often used to describe natural selection, but it can be misleading because it suggests that survival is a matter of strength or power.

However, natural selection actually favors organisms that are better suited to their environment, which may involve a variety of traits such as speed, camouflage, or the ability to survive on limited resources. The traits that are favored by natural selection are passed on to the next generation, while less advantageous traits are not.

Natural selection operates on the genetic variation that exists in a population, and the outcome of natural selection is the adaptation of organisms to their environment.

According to the data, the statement that is best supported by the data is that the population is evolving and there seems to be selection against the genotypic CyCy.

The Hardy-Weinberg equilibrium is a genetic principle that suggests that if no other forces were involved, genotype and allele frequencies would stay constant from one generation to the next, and evolution would not occur. The principle is used to evaluate whether a population is experiencing evolutionary changes. The Hardy-Weinberg equilibrium is a mathematical relationship between the frequencies of alleles and genotypes in a population that is not evolving. It describes a theoretical population that is at equilibrium with respect to one or more gene loci and provides a baseline for estimating evolutionary forces acting on populations.

In a given population, the Hardy-Weinberg equilibrium is a good model for describing the transmission of alleles to the next generation in the absence of mutation, migration, genetic drift, or natural selection. When genetic data from a population deviate from Hardy-Weinberg equilibrium expectations, this might suggest that one or more of these evolutionary forces are acting on the population.

There are three main types of bipedalism: facultative, obligate, and facultative-obligate.

Facultative bipedalism is the most common, and it occurs when primates walk bipedally but also move around on all fours. Examples of primates with facultative bipedalism include baboons, chimpanzees, and gorillas. These primates use bipedalism as a way to transport objects, to feed, and to reach things that are otherwise out of reach.

Obligate bipedalism occurs when primates move around on two legs only and do not move around on all fours. Humans are a classic example of obligate bipedalism, as we are almost exclusively bipedal when we move around. Other primates who exhibit obligate bipedalism include macaques, vervets, and lorises. They use bipedalism to navigate through dense forests, which is helpful for accessing fruits and other resources in the treetops.

Finally, facultative-obligate bipedalism occurs when primates occasionally move around on all fours and at other times move around on two legs only.

Meiosis II and Mitosis both involve the separation of sister chromatids. In mitosis, this occurs during the anaphase stage, where spindle fibers pull apart the sister chromatids towards opposite poles of the cell. In meiosis II, sister chromatids are separated during the second round of division after the cells have already undergone meiosis I.

Mitosis results in diploid cells, this is because, during mitosis, the parent cell replicates its DNA, separates the sister chromatids, and divides the cytoplasm to produce two genetically identical daughter cells with the same number of chromosomes as the parent cell.

Meiosis I is the process that separates homologous chromosomes. During this process, the two homologous chromosomes (one from each parent) pair up and exchange genetic material in a process called crossing over.
