Hello. Giraffes with longer necks survive compared to those with shorter necks because of natural selection. Over time, natural selection favors the traits that would make a species thrive better in the environment. Giraffes with short necks won't have access to that much food compared to those with long necks thus they eventually died out.
ANSWER: natural selection.
Answer:
thymine(t)
cytosine(c)
56
44
35
Explanation:
A always pairs with T, so 56 A's will pair with <u>56</u> T's
G always pairs with C, so 44 G's will pair with <u>44</u> C's
100 base pairs means there are 200 bases present altogether
out of 200, we have 65 T's so ultimately we will have 65 A's
we are now left with 70, of which have will be C and half G, which gives 35 C's and G's
