C. m P
Explanation:
Due to the extreme low temperatures were generated by the air blowing from Siberia to particular direction. But almost in parallel direction.
Initially by meiosis and then by mitosis.
This question is confusing. What I can tell you though, is that mitosis is the process in which cells divide and cause the animal fetus to grow, but it is meiosis that ensures the animal can develop as a fetus initially. (The 4 resulting haploid cells form a sperm gamete and an egg gamete, and they come together to form a zygote, which eventually develops into a fetus)
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.
A should be ur answer due to more technological advances
