(C) Based on the data, identify the population that is likely to have the highest frequency of heterozygous. Assuming random mating, calculate the frequency of animals in population 1 that carry both alleles 1 and 3
Answers
Answer:
The frequency of animals in population one to carry both alleles in 1&3 is .85%.
Explanation:
Just did the FRQ, hope that this helps. Please mark me brainliest! Peace and Love
According to the Hardy Weinberg equilibrium, the frequency of animals in population one to carry both alleles in 1&3 is 0.85
What is Hardy Weinberg equilibrium?
Hardy–Weinberg Equilibrium (HWE) is a null model of the relationship between allele and genotype frequencies, both within and between generations, under assumptions of no mutation, no migration, no selection, random mating, and infinite population size.
by using this equation p²+q²=1
Hence, Hardy Weinberg equilibrium, the frequency of animals in population one to carry both alleles in 1&3 is 0.85

The cladogram shown below describes the evolutionary relationship among several species, labeled A to F. The five dots represent derived characters.
A cladogram includes a line with 5 dots. From bottom to top, the dots are labeled Trait 1 to Trait 5. Branches from the line lead to tips labeled A to F. Labels C and D are at the ends of very short branches off a longer branch.
The cladogram supports which of these predictions about the genomes of the six species?
A. The genome of species E is equally similar to the genomes of species D and F.
B. The genome of species E is more similar to the genome of species F than to any of the other species.
C. The genomes of species C and D are nearly identical because neither species has a derived character.
D. The genomes of the six species share few, if any, DNA sequences.
Answers
(You will find the cladogram in the attaches files)
Answer:
C. The genomes of species C and D are nearly identical because neither species has a derived character.
Explanation:
A Cladogram is a tree-type graph based on cladistic analysis. It represents the common ancestral relationships among the involved groups.
The tree-type graph is a ramified diagram that represents the relationship between the involved taxa. The cladistic analysis follows the maximum parsimony criterium. Explains the character state from the point of view of the fewest changes through history. Explains evolution with the minimal amount of evolutive changes. It recognizes the monophyletic groups as natural groups. These groups are the clades, and their classification -sequencing- represents their phylogeny. The sequencing term refers to lists of groups according to their relation. One group is the brother-group of the following one.So the cladogram represents the relationship between groups according to a derived character.
The derivated character is any trait that a group passes to the descendants. Through evolution, the characters change, and new changes are added. When referring to a derivate character, we mean that all the subsequent species in the cladogram carry the trait.
A cladogram provides an image of how new species keep characters that were inherited from older species.
So, in the exposed example, the five dots represent derived characters, representing traits 1 to 5. Branches A to F, represent groups. (See the cladogram in the attached files). Group A inherited trait 1, group B probably still carries trait 1, but also trait 2. Groups C and D equally inherited trait 3. Group E inherited character 4, and finally, group F inherited character 5.
Groups C and D inherited trait 3 and probably also still have traits 1 and 2. So they are very similar to each other. At a certain point, they diverged, probably due to a new mutation that was not passed to the rest of the group.
C. The genomes of species C and D are nearly identical because neither species has a derived character. Correct.

How is the formation of RNA similar to DNA replication?
Answers
Answer:
Both DNA replication and Transcription involve the generation of a new copy of the DNA in a cell. DNA transcription is involved in replicating the DNA into RNA, while the DNA replication makes another copy of DNA. Both the process is involved in the production of new nucleic acids- DNA or RNA.
Explanation:
The formation of RNA is similar to DNA replication because both processes require an analogous enzyme (Polymerase).
What is DNA replication?DNA replication refers to the process of duplication of the genetic material before cell division (either mitosis or meiosis).
DNA replication requires different enzymes such as DNA polymerase, ligase, RNA primase and topoisomerase. Moreover, RNA replication or transcription also requires a nucleotide polymerase (RNA pol), which uses DNA as a template to generate complementary RNA.In conclusion, the formation of RNA is similar to DNA replication because both processes require an analogous enzyme (Polymerase).

What factors caused the correlation between the reduction in skin pigmentation in humans and migration of human populations away from the equator?(1 point)
A) The exposure of human populations to predators only common to the polar regions caused them to adapt by camouflaging better with the environment.
B) The exposure of human populations to less UV light required a reduction in melanin to produce more vitamin D for healthier bones.
C) The exposure of human populations to new sources of food common to the polar regions caused changes in physiology that resulted in the production of less melanin.
D) The exposure of human populations to new diseases common to the polar regions interferred with melanin production causing lighter skin.
Answers
The exposure of human populations to new sources of food common to the polar regions caused changes in physiology that resulted in the production of less melanin.
What is relation of skin colur with geography?Skin color is lighter at high latitudes as compared to equator region beacuse of lower sunlight at higher altitudes and at polar regions. So due to less sunlight, less melanin is produced in our skin.
So we can conclude that option C is the right answer.

Why is it difficult to avoid a tsunami?
Answers
Answer:
It is difficult to avoid a tsunami due to it being such a large volume of water that is capable of destroying a large amount of land.
Explanation:
However, even though it is difficult to avoid a tsunami, as they are extremely difficult to predict, there are ways where one can begin to prepare before it hits. One of the ways you can do this is getting to a higher ground far away from inland, avoiding downed power lines, and steering clear of buildings or bridges where large, heavy objects could fall during an aftershock.
Tsunamis are incredibly dangerous, since there is a great chance that if you get caught in one, you can drown. Since tsunamis have little to no warning when they arrive, it is always essential to be prepared when one strikes.

Which is an effect of a compromised immune system?
decreased antibody production
improved ability to fight disease
increased lymphocyte production
reduction in pathogens entering the body
Answers
Answer:
A: Decreased antibody production
Explanation:
It's the only one that makes sense when you think about it.
Decreased antibody production is an effect of a compromised immune system. So, the correct option is A.
What is an Immune system?The immune system is a complex system of cells, tissues, and organs that cooperate to defend the body against foreign pathogens, including bacteria, viruses, and fungi, as well as other dangerous chemicals. It plays an important role in maintaining the health of the body, by discriminating between foreign invaders and the body's own healthy cells and tissues.
White blood cells of all stripes, including lymphocytes, phagocytes, and natural killer cells, as well as other specialized cells and substances, including antibodies, complement proteins, and cytokines, make up the immune system. Together, these proteins and cells help the body recognize and destroy invading invaders.
Therefore, the correct option is A.
