b.conditions in an organisms environment ensure the organisms survival
c.birds and reptiles share a number of inherited characteristics
d. tigers are so different from cheetahs
Answer:
The correct answer would be c. birds and reptiles share a number of inherited characteristics.
In evolutionary biology, the principle of common ancestors or descent explains how different groups of organisms share a common ancestor.
In other words, different groups of organisms are believed to evolve from a common ancestor.
The groups which share recent common ancestor share a number of common inherited characters.
The groups which share distant common ancestor share less common characters.
Thus, birds and reptiles share a number of characters as they have evolved from common descent or ancestor.

Now, since velocity is defined as the displacement experienced by an object in a specified direction, it is therefore correct to call velocity a vector
I believe that the answer is C, adenine.
First of all, there are 46 individual chromosomes (23 pairs) in a human cell.
What happens in mitosis is that the original cell copies its DNA (so there are 2 sets of 23 pairs. In the end, after cytokinesis takes place, each daughter cell will have 23 pairs (46 chromosomes).
