Answer: false, for example, if a frog eats flies, and the flies are land animals, if they go extinct the frogs could die off, meaning any fish or water dwellers that eat the frogs can starve and cause a large chain reaction.

Hope this helps ^^

Cells can make proteins that need to be transported out of the cell and moved to another part of the body. Cells also make carbo

alex41 [277]

Answer:

The proteins will be transported through exocytosis; the carbon dioxide will diffuse through the membrane.

Explanation:

Diffusion is the passive transport of substances down their concentration gradient. The process moves the substances from the region of higher concentration to that of lower concentration. CO2 is a small molecule and does not have any charge. Small, uncharged molecules can diffuse through the lipid bilayer of the cell membrane. Therefore, CO2 can exit a cell by simple diffusion.

On the other hand, proteins are too large to be transported by diffusion across the cell membrane. The proteins are transported by exocytosis. During exocytosis of proteins, membrane-bound vesicles are formed inside the cell. These vesicles carry proteins in them and are called secretory vesicles. The membrane of the vesicles fuse with the cell membrane of cells and transport the proteins outside the cell.

Cats have a gene that codes for the color of their fur.

madam [21]

Punnet square
Let's call black 'B' and white 'b'
Being intermediate, gray cats will have the alleles 'Bb'
Being recessive, white cats will have the alleles 'bb'
 Gray 
| | B | b |
White |b| Bb | bb|
|b| Bb | bb|

^Apologies for the awful drawing XD

Bb = Gray
bb = White
So the cats can have gray or white fur (A)
