Answer:
Endocytosis= movement of large molecules into a cell, then digestion occurs in the cell.
Exocytosis= movement of wastes from the cell.
Explanation:
Here are some examples of Endocytosis and Exocytosis:
Endocytosis= Example 1: food of Euglena, paramecium
Example 2: WBCs engulfing bacteria
Exocytosis= Example 1: wastes removal from cell
The answer would be D.
In binary fission the singular DNA strand is broken down and replicated, whereas in mitosis multiple different types of chromosomes are replicated.
If water had no density - if its mass per unit volume were zero - it would be massless, and would travel at the speed of light.
The oceans would all go in all directions (leaving sea-dwelling flora and fauna behind - and all the salt).
You wouldn't see rain coming (at least, not directly at you), because the image of the rain would travel no faster than the rain itself.

global warming is bringing us a lot of hurricanes for example since hurricanes need warm ocean water and winds but humans are causing global warming and are helping these damage more and more of our world from buring fossil fuels, using motor vehilces instead of biking or walking. etc we are causing the water to heat up and circulate more which means more hurricanes
