Answer:
C
Explanation:
The cell wall in only present in plant cells, not animal cells. Hence, the fact that plant cells are rectangular while animal cells are more circular.
Answer:
B is most likely used for reproduction.
Answer:
"Proton decreases" would be the right approach.
Explanation:
- The Kreb cycle or system plays a key role throughout a matrix of mitochondria. 3 NADH, 2 FADH2 as well as 1 ATP are synthesized.
- Whenever the Kreb process has been halted, the acetyl CoA throughout the Kreb cycle has not been used. Pyruvate doesn't at all, disintegrate via acetyl CoA. Therefore in cells, pyruvate accumulates.
- Unless the Kreb loop is halted, therefore the concentration of NADH and FADH2 declines.
Thus, they aren't used for the transportation chain of electrons. This is also why protons have not been discovered to be injected towards intermembrane space.
Hi there!
As resources in a population become less available, the population:
C. Reaches carrying capacity
When resources in a population become less available, the population will not be able to continue growing even more because there would be enough resources, and so, it has reached its carrying capacity.
When the exponential phase of a logistic growth curve of a population ceases:
C. Population growth begins to slow down.
The population will continue to grow but will do so at a slower and steadier rate.
I hope that helps! :)
Cell is limited in size for many reasons. Cells wouldn't be respire effectively if it were too large, because the surface area to the volume ratio would be too small.
The other thing is that if the cell were too large, it would be difficult for it to move nutrients and waste products in and out of the cell. So, cells are limited in size.
