How is phospholipid bilayer arranged? and why does it arrange that way?

Biology
1 answer:
Ainat [17]3 years ago
4 0

The majority of the similar genes in the mice and humans is the indication that they have evolved from a common ancestor not very long ago. However, only 60% similarity between fruit flies and humans indicates that it had been some time since they both have had a common ancestor.

Hope it helps

Explanation:

The oncotic pressure inside the cell will be greater than the pressure outside. Thus causing the cell membrane to rupture.

What special adaptation do strawberry plant stems have
cupoosta [38]
I am thinking of of strawberry runners, also called stolons:

these an a sort of extrernal connections between the particular plants, which can be used to grow new plants, as when the end of one such stem finds an appropriate place in the ground and sprouts roots there.

Do you think you might have needed a different kind of adaptation?
