Answer:

Exocytosis is the reverse of endocytosis. <em><u>Quatities of material are expelled from the cell without ever passing through the membrane as individual molecules.</u></em> By using the processes of endocytosis and exocytosis, some specialized types of cells move large amounts of bulk material into and out of themselves.
Answer:
A
Explanation:
If it's a permeable membrane then it will allow certain molecules in. If it's impermeable then it won't allow molecules in. Therefore it is the deciding feature of whether something can go into the membrane.
It will take in too much, swell up, and eventually burst.
If it contians 1/16th the amount, it must have gone through 4 half lives: 1> 1/2> 1/4> 1/8> 1/16>.since the half-life of c-14 is about 5730 years, the age of the fossil is 4 X 5730 years or about 22,920 years old.
