What do the rib muscles and diaphragm have in common?

Biology
1 answer:
Hatshy [7]2 years ago
3 0

Answer:

Both are breathing muscles

Explanation:

When rib muscles and the diaphragm contract they increase the volume of the chest cavity, increasing the air pressure outside the body, causing air to rush into the lungs to fill the vacuum created by the increase in volume.

Multiple Select Question

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.

strojnjashka [21]

Answer:

C, a decrease in metabolic activity

Explanation:

In times of drought, there would be a reduction in the metabolic activity of an organism.

  • Most organisms found in very dry climates have adaptation to accommodate a period of drought.
  • Water is essential for the metabolic processes in an organism.
  • A deficiency of water will reduce these life activities.
  • The organism can become inactive as a result of this.
