Sorry I am late on answering the question, if u don’t know what it is still, the answer I believe is D!
Answer:
Polysaccharides are an important class of biological polymers. Their function in living organisms is usually performed one of two functions: energy storage or structural support. Starch and glycogen are highly compact polymers that are used for energy storage.
Explanation:
Answer:
The correct answer would be - oxygen will passively diffuse into the cells.
Explanation:
As the oxygen molecules are very small and has no polarity or no charge they show the passive diffusion through the plasma membrane from the higher concentration to lower concentration inside the cell.
In the lungs the oxygen diffuses out the air sacs into the blood as the air sacs of lungs have higher concentration of oxygen than the blood stream and as the various cells perform the aerobic cellular respiration the concentration of the oxygen inside of the cell become low to the blood so oxygen diffuses into cells.
Thus, the correct answer is - oxygen will passively diffuse into the cells.
Answer:
D) 60 i think
Explanation: in 2016 the rural population was 20 and the urban population was 60 so if you start counting from 20 in 2016 up to 80 in 2016 its 60
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.
