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.

(b) Many amphibian species throughout the world are endangered
Suggest three reasons why many amphibian species are endangered
Answers
Answer:
The correct answer is - habitat loss, pollution and disease, and climate change.
Explanation:
Many amphibians are endangered due to several reasons including, habitat loss, climate change, pollution and disease, non-native species invasion, and many others. Amphibians are mostly live in damp habitats or moist soil and low-level water and these habitats are destroys due to pollution, deforestation or excess fishing.
Pollution and disease also affect these species most specifically chytridiomycosis, caused by the chytrid fungus was an epidemic for many amphibians. Climate change also affects the temperature and soil quality precipitation of the habitat that not suitable for these species.

Which factor could have allowed the population of black peppered moths to increase in the late 1800s? (1 point)
less rain
less vegetation
Less food
less predation
Answers
Natural selection favored the population of black peppered moth. This led to less predation and increased population of black peppered moth.
What is natural selection?The natural selection is the process to adapt and change according to the changing environment by organisms.
Initially there were both white and black peppered moths were present. It was recognized that the camouflage of white moth was not worked in dark forest.
This caused mutation in them and changed their wing color to darker shades.
This led to less predations as they were no more recognizable in dark forest due to their dark wings.
Thus, the correct answer is d.

Yes, the rate of exposure (the amount of contacts) will affect an individual’s chance of becoming infected

Yes, the rate of exposure (the amount of contacts) will affect an individual’s chance of becoming infected

The founder effect is a type of genetic drift in which a small population is isolated. Due to this isolation, the population may have different gene frequencies than the rest of the larger population.
