Answer:
At the time of inspiration, contraction of diaphragm takes place that enhances the chest cavity.
Explanation:
One of the prime muscle that takes part in the process of respiration is the diaphragm, which is situated below the lungs. It is a dome-shaped and large muscle, which spontaneously goes through a contraction, and largely the process takes place involuntarily.
The contraction of diaphragm takes place at the time of inhalation, which flattens and increases the chest cavity. Due to the contraction, a vacuum is generated that makes the air to get in within the lungs. In contrast, the diaphragm relaxes at the time of exhalation and moves back to its original shape, thus, making the air move out of the lungs.
<u>The function of a protein determined by:</u>
The shape determines the working of a protein. A protein's design is determined by its primary structure i.e the amino acid sequence. The amino acid sequence within a protein is decided by the encoding arrangement of nucleotide in the gene (DNA).
The role of a protein is utterly dependent on its three-dimensional architecture (other than when it caters as food). This framework may be disturbed by a number of agents thereby denaturing the protein:
- Variations in the pH (between charged amino acids the electrostatic interactions is changed).
- difference in concentration of salt (does the same).
- temperature change (higher temperatures decrease the strength of hydrogen bonds).
- reduction agent presence (disruption of S-S bonds among cysteines).
Answer:
There are over 60, 000 species if trees; however, there are 101 different tree types.
Explanation:
Globally its over 60,065 species of trees but the question asked how many different types of trees are there and the answer is 101 according to www.homestratosphere.com
