Answer:
little pouches
Explanation:
the aleveoli are like small balloons, but not large ones. they exchange oxygen and carbon dioxide molecules (so they contain small amounts of air like a SMALL balloon, or in this situation a small pouch).
Its important because they produce offspring. Without any offspring the species would slowly die off and become extinct.
Answer:
C) A + T = G + C
Explanation:Erwin Chargaff suggested the rule of the base pairing of DNA structure which is that purine binds pyrimidine or adenine binds thymine and guanine binds cytosine.
The composition of adenine and thymine and guanine and cytosine equals 100 percent.
In the given question, since option C shows that A binds T and G binds C and their composition equals 100%, therefore, Option-C is the correct answer.
Thus, Option-C is the correct answer.
