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.

Answer:
The distance between them is changing at the speed of 10.16 m/hr
Explanation:
Consider the sketch attached below.
The question is simply asking to calculate the resultant of the two velocities.
To get the angle between them, we simply use the coordinates of the two vectors to determine the angle between them.
90 + 45 = 135°
from the cosine rule we have
= 
+ 
- 2abcosθ
= 
+
- 2 ×6×5×cos 135
= 103.426
c = 
c = 10.17 m/hr
The correct answer is: the mother cell is diploid, but the products of the first division are haploid.
Meiosis is cell division with the purpose to produce the gametes: sperm and eggs. Meiosis is a two-step division process:
• meiosis I- Homologues pairs (chromosome pairs an organism receives from parents, one from mother, one from father) separate during this phase
• meiosis II – Separation of sister chromatids.
