1-The correct answers is C- evolutionary classification.
Evolutionary classification/taxonomy is a branch of biological classification. The objective is to classify organisms and group them based on their shared descent, progenitor-descendant relationship and degree of evolutionary change. Now this classification can be done by comparing DNA sequences of the organisms and seeing how many they have in common

2- The correct answer is A-cladistic analysis.
A cladistic analysis is focused on categorizing the organisms based on their derived characters. And what is that? that means they are getting categorized
according to their evolutionary relationships( from ancestral characters).
So, species are going to be classified according to how recent their common ancestor is. If two species have a more recent ancestor they will end up in the same group
If the common ancestor between them is far, the distance between the respective taxa will be bigger.

3- The correct answers is C.
A derived character is a characteristic that appeared throughout evolution, still remains in a lot of different taxonomic groups and allows us to identify those groups.
From the options given, C is the only correct one because the presence of hair (a derived character)  only exists in mammals( the group). Other animals don't share that trait.


4-The answer is A.
In each node, a taxon was only one but then was divided into two taxa. Therefore, each node will represent a common ancestor of the taxon.
The correct option is A because the last node or terminal node is the hypothetical last common ancestor of the taxon on the cladogram.

5-  The correct answer is A.-DNA can solve evolutionary puzzles.
Dna has been helping understand how an organism is similar to more than one species, and that way, we can classify the organism the best way possible.
This can be achieved by comparing the nucleotides of the organism we want to classify, with other species. There are databases that have all the DNA sequenced so, what's left to do is count the common nucleotides and their positions.

Which is a result of a seasonal change (meaning a change that happens over
weqwewe [10]

Answer:

A. Chipmunks sleeping underground through the winter

Explanation:

A seasonal change in the behavior of a living organism is a change that occurs every year at a particular time. The reasons for the occurrence of such changes are so that the organism has advantage in survival in the environment. In this case we have the chipmunk that sleeps underground through the winter. We have an animal which exhibit a seasonal change every year, during the winter period. The reason for this is that the chipmunks have very quick metabolism, so if they are active during the winter they will starve because of lack of food. Instead, the chipmunks have evolved to hibernate during the winter, thus slowing down the work of their hurt during the winter and sleep, until the spring comes.
