If a population of deer exceeds its carrying capacity, it is likely that the
marusya05 [52]
The amount of deer moving about in urban areas would increase. Instead of being in their natural habitat, deer would be walking around, grazing in the yards of humans to try and find food. This may also lead to an increase in wildlife related collisions, as more deer would be trying to cross busy roads to find more to eat.

Multiple Select Question
Diano4ka-milaya [45]

The TRUE statements are 'proteins often have more than one transmembrane domain'; 'they are regions of a transmembrane protein that actually pass through the lipid bilayer' and 'they are usually shaped like alpha-helices'.

A transmembrane domain is a membrane-spanning region within a protein. The transmembrane domains are hydrophobic regions that can be inserted into the cell membrane.

The transmembrane domains are usually shaped like alpha-helices.

This secondary structure (alpha-helices) causes the amino acid R-groups to project radially, thereby these side chains can interact with each other.

Proteins need only a single transmembrane domain to be anchored to the membrane, but they often have more than one.

For example, Acyl-coenzyme A cholesterol acyltransferases 1 and 2 (ACAT1 and ACAT2)  have multiple transmembrane domains.

The transmembrane domains are regions of a transmembrane protein that actually pass through the lipid bilayer.

These domains contain amino acids with hydrophobic R-groups that pass through the membrane and interact with the hydrophobic tails of the fatty acid chains present in the lipid bilayer.

The transmembrane domains anchor transmembrane proteins to the lipid bilayer.

The interactions between amino acids of the transmembrane domains and fatty acids in the lipid bilayer help to anchor transmembrane proteins and stabilize the cell membrane.
