Answer:
Question 8. The correct answer is D: "A butterfly population includes both green and yellow butterflies, and a predator sees yellow more easily than it does green".
Question 9. The correct answer is graph C.
Question 10. The correct answer is C: "The fact that the bone structures are similar supports the theory that the animals shared a common ancestor".
Explanation:
Natural selection is the result of the phenotype-environment interaction which determines gene destiny in space and time, selecting beneficial alleles and increasing their frequency in the population. Natural selection can lead to speciation, driving to evolution. There are different types of natural selection: sexual selection, stabilizing selection, directional selection, frequency-dependent selection, and disruptive selection.
The exposed example: "A butterfly population includes both green and yellow butterflies, and a predator sees yellow more easily than it does green", is an example of directional selection.
Directional selection increases the proportion of individuals with an extreme phenotypic trait. In the example, natural selection will favor the green trait in butterflies over yellow, because as predators see better the yellow ones, these butterflies have more chances to be eaten. So the population must evolve to green traits to avoid predation.
Disruptive selection occurs when selective pressure favor homozygous. In equilibrium, the two alleles might be present or one of them might be lost. If an environment has extremes, then in these environments, both alleles are presented in homozygous.
The disruptive selection causes an increase in the two types of extreme phenotypes over the intermediate forms.Limits between one extreme and the other are frequently very sharped. Individuals belonging to one phenotype can not live in the same area as individuals belonging to the other phenotype, due to the traits differences between them, competition, predation, etcetera.
Both extreme phenotypes have been favored over intermediated forms. In this way, populations show two extreme phenotypes and a few individuals in the middle. Individuals who survive best are the ones who have traits on the extremes forms. Individuals in the middle are not successful at survival or reproduction.
Disruptive selection can lead to speciation, driving to evolution. This is why it is also called "diversifying selection".
The graph representing this selection must show two pics, spacially separated from each other, reflecting the two extreme phenotypes in the population.
Classification of the biologic diversity intends to reflect the evolutive process that made a place to different organisms. This is estimating phylogeny, and it refers to the reconstruction of the evolutive ways that resulted in different groups. Estimating phylogeny can be based on characters, and these last ones might be morphological, physiological, cytological, among others.
Apomorphies and plesiomorphies are homologous characters shared by an ancestor and its derivated groups.Two characters are homologous if they share the same fundamental structure, if they share the same embryologic development, or if they share relation with adjacent structures. This is the case of the bone structures.
A bat wing, an alligator leg, a horse leg, a dolphin flipper, and a human arm are homologous structures. This is an ancestral homology, a character inherited from a common ancestor.
A common ancestor that is exposed to different pressures in different environments suffers changes in time as a result adaptation to the new environmental conditions. These changes lead to diversification and speciation.
The fact that the bone structures are similar supports the theory that the animals shared a common ancestor.

Answer:
(1)Substrate, (2)Product and (3) active enzymes.
Explanation:
Enzymes are bio catalysts that increases the rate of a biochemical reactions. The enzymes has the ability to work at specific temperature and pH conditions only.
The enzyme binds with the substrate in a biochemical reaction and decreases the activation energy of the reaction. After that the substrate is converted into the product and active enzyme leaves the reaction.
Thus, the correct answer is (1)Substrate, (2)Product and (3) active enzymes.
The F1 progeny will all have the genotype Zz and will all have normal feathers. When the F1 progeny are interbred, the F2 progeny will have the following genotypes and phenotypes:25% ZZ (bald)25% Zz (normal)50% zz (normal)The expected proportions for the F1 and F2 progeny are as follows:F1: 100% Zz (normal)F2: 25% ZZ (bald), 25% Zz (normal), 50% zz (normal)
In chickens, congenital baldness is due to a z-linked recessive gene. T
his means that the gene for baldness is located on the Z chromosome and an individual must have two copies of the recessive allele to exhibit the bald phenotype.
The bald rooster has the genotype ZZ, meaning he has two copies of the recessive allele. The normal hen has the genotype Zz, meaning she has one copy of the recessive allele and one copy of the dominant allele.
When these two individuals are mated, all of the F1 progeny will have the genotype Zz and will have normal feathers. When the F1 progeny are interbred, the F2 progeny will have the following genotypes and phenotypes:25% ZZ (bald)25% Zz (normal)50% zz (normal)
The expected proportions for the F1 and F2 progeny are as follows:F1: 100% Zz (normal)F2: 25% ZZ (bald), 25% Zz (normal), 50% zz (normal)

Explanation:
Answer:
Species C.
Explanation:
The bands of the unknown species most closely align with those in the Species C column.
To identify the closest relative to an unknown species, scientists utilize phylogenetic trees and genetic analyses, which suggest that species positioned nearer to each other, like species D and E, are more genetically similar due to their recent common ancestry.
To determine the most closely related species to an unknown species, scientists often use phylogenetic trees and genetic analyses. A phylogenetic tree showcases the evolutionary relationships among various species, suggesting how recently species have diverged from a common ancestor. If performing a genetic analysis on species, it is expected that species that are positioned close to each other on the tree — such as species D and E — will share more genetic similarities, due to a more recent common ancestor. On the contrary, species that are positioned further apart, such as species A and B relative to species D and E, would share fewer genetic similarities as they would have diverged earlier in the evolutionary timeline.
An accurate phylogenetic tree based on certain characteristics like the circulatory system can elucidate the phylogeny within vertebrates. Additionally, dissecting and analyzing the digestive system of a new species can provide insights into its relatedness to known species, depending on which animals have a similar digestive configuration. Finally, cataloging and understanding biodiversity, including prokaryotic species, is essential as species extinctions accelerate, highlighting the significance of studying evolutionary relationships to comprehend the full tapestry of life on Earth.
