Answer:
The orchids derive nutrients from the association at very young stages of its life cycle while the fungi obtain water and organic matter
Explanation:
As stated in this question, fungi species belonging to the phylum Basidiomycota form mycorrhizal associations with a flowering plant called orchids. This relationship is a mutualistic one because both participants benefit from the relationship.
In this association, the young orchid plant relies on the mycorrhizal fungi's metabolism to get nutrients needed for its development in form of carbohydrates while the fungi in return gets water (from the roots of the plant) and organic matter.
B, because if you think about it, you're climbing a mountain and the mountain is at a very high elevation right? it is very cold and the pressure of the air is high. now when you go down, it gets warmer and the pressure isn't as bad.
Selective permeability, made possible in cells by the phospholipid bilayer that makes up the plasma membrane, is basically monitoring and regulating what can and can't enter the cell. It is carried out by a series of membrane proteins that act as channels to polar molecules, opening to allow them in and closing to prevent their entry. This is possible because the hydrophobic tails of the phospholipid molecules repel polar molecules and so prevent their entry unless through a channel.
Answer:
Explanation:A few types of differentiated cells never divide again, but most cells are able to resume ... life to replace cells that have a high rate of turnover in adult animals. Cell proliferation is thus carefully balanced with cell death to maintain a constant ... Cells of this type include skin fibroblasts, smooth muscle cells, the endothelial cells ...
