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.
Answer:
B. 100 percent yellow seeds
Explanation:
When a gene has two alleles and one allele is dominant over the other, the dominant allele is expressed in the heterozygous state and the expression of the recessive allele is masked. According to the given information, the allele for yellow seed color is dominant over the allele for the green seed color.
Let's assume that the allele "Y" gives yellow color to the seeds while the allele "y" is responsible for green seed color. A cross between two pure breeding yellow seeded (YY) and green seeded (yy) plants would produce all the yellow seeded progeny with genotype "Yy".
YY (Yellow) x yy (green) = Yy (yellow)
