I think it’s b but idk i’m learning that in science as well
Mitosis and cytokinesis. In eukaryotes the processes of DNA replication and cell division occur<span> at different times of the </span>cell division<span> cycle. During </span>cell division<span>, DNA condenses to form short, tightly coiled, rodlike chromosomes. Each chromosome then splits longitudinally, forming two identical chromatids.

Answer:
1) B - protein channel
2) D - to assist in the movement of substances across the membrane by facilitated diffusion or active transport
Explanation:
1) B is the answer because the proteins would travel through the protein channel to enter or leave the cell.
2) D is the answer because the channel allows protein molecules to pass through a selectively permeable cell membrane through active transport and facilitated diffusion.
Hope this helps!
The geosphere has four subsystems called the lithosphere, hydrosphere, cryosphere, and atmosphere. Because these subsystems interact with each other and the biosphere, they work together to influence the climate, trigger geological processes, and affect life all over the Earth.
<u>Answer:</u>
<em>A constant is something whose value cannot be changed and is used for comparison purpose. </em>
<u>Explanation:</u>
The controlled variable is a type of variable whose value is kept constant during the experiment to get the desired or expected result. The difference between constant and a control variable is that the constant can never be changed.
However, the value of control variable can be changed but is kept constant with a purpose in an experiment to get the data. The controlled variable in a battery can be the multi meter that should be used for all the batteries.
