Answer:
D. Active transport.
Explanation:
Active transport is the method that uses the ATP's energy to move ions and molecules from one side to the other of the membrane. The elements move from a place of lower concentration to one of a higher concentration. They move against their concentration gradient, which is why they need the energy to do it. There are two types of active transport, primary and secondary.
The primary active transport is ion pumps that hydrolyze ATP using one of the phosphates of the ATP to change the pump's shape and move the elements against their concentration gradient. It uses the ATP's energy directly.
The secondary active transport does not use ATP directly. It uses the electrochemical gradient that the primary transport had created when hydrolyzing ATP to transport the ions and molecules.
I do not know how the phylogeny chart you have is, but it probably contains a series of apes, gorillas and Homo sapiens.
We know that gorilas don't walk upright, but Homo sapiens do. What you will probably have to do is situate the new species of ape somewhere in between gorilas and humans, in a way that the new species shares a common evolutive path with both.

Answer: 805m east
Explanation:
From the data above v=23m/s, t=35s
Average velocity= Displacement/Time.
Displacement= Average velocity X Time.
Displacement= 23 X 35= 805m
So, the correct answer is 805m east.
Answer:
In the anaphase, this is where the magical part of the process occurs. The chromosomes coil, and separate along with the centrosomes. Spindle fibers shorten and/or form, and the sister chromatids align in the equator of the cell.
