How does the movement of materials across the cell membrane relate to an organism’s survival?

Biology
1 answer:
ioda3 years ago
8 0

I believe it relates because as we know the cell membrane is permeable meaning that allows oxygen, carbohydrates, food to enter the cell but it doesn't allow the entrance of large molecules that harm the cells.

After all the movement around it, matters because for example without food the mitochondria won't be able to create the energy and then with that energy, the nucleus to use it to complete the main the activities of the cell.

Hopefully this what you meant when you asked the question. Have a nice day/evening

The length of linker DNA segments varies somewhat among organisms. The length of the linker DNA in sea urchin is 110 base pairs.
nasty-shy [4]

Answer:

362 nucleosomes

Explanation:

A nucleosome repeat is made up of the DNA (146 bp) wrapped around the core nucleosome particle and the linker DNA (110 bp as in this situation). We can conclude that, every repeat stands for 256 (146 + 110) base pairs of DNA.

We are given the length of the entire region to be 92,672 bp long,

To determine the number of nucleosomes to organize the region into the 10nm fiber structure

Let,

Number of nucleosomes =

the length of the entire region

------------------- -----

base pairs of DNA.

= 92,672

-------

256

= 362 nucleosomes

Therefore, 362 nucleosomes is needed to structure the region into the 10nm fiber structure.

Part 1: Why is Fresh Water in Short Supply?
shepuryov [24]

Part 1;

Because there is only limited amounts of fresh water on the Earth the rest is salt water; which humans can not survive on as the salt dehydrates our bodies instead of hydrates.

1) The more we try to get the the fresh water the more we will likely make more pollution.

2) The more we use the less there is.

3) Everything needs water.

Part 2; no idea I believe it is the ice caps, as it is fresh water in the ice caps and not a lot of humans up there to pollute the runoff.
