Answer:
D. Carbon dioxide and water vapor
The answers include the following:
- The respiratory system gave the cells more oxygen via breathing to perform various activities.
- The endocrine system released hormones such as adrenaline to activate chemical changes and stay alert.
- The nervous system carried electrical impulses necessary for the contraction and relaxation of muscles.
- The bones and muscles worked together to ensure adequate movement.
<h3>What is Musculoskeletal system?</h3>
This is the system which comprises of bones, ligaments etc and ensure that the body system has a rigid structure.
It also ensures organisms are able to move from one place to another in search of food and for their survival.

Answer:
2 n = 61 Chromosomes
Explanation:
If the plants that are produced are fertile then they must have a chromosome number hybrid of previous two species and that is 122. This is an example of tetraploidy. It is crucial that the chromosome number of the species should be even otherwise the pairing will result in a mismatch and the produced offspring will be a sterile hybrid.
Answer:
The frequency of the Y allele is 0.7
The frequency of the y allele is 0.3
The frequency of the YY homozygote is 0.49
The frequency of the Yy heterozygote is 0.42
Explanation:
According to Hardy-Weinberg Equilibrium,
p + q = 1
p² + 2pq + q² = 1
where,
p = frequency of dominant allele
q = frequency of recessive allele
p² = frequency of dominant homozygous genotype
2pq = frequency of heterozygous genotype
q² = frequency of recessive homozygous genotype
Here,
yy = q² = 0.09
frequency of y allele = q = √0.09 = 0.3
frequency of Y allele = p = 1-q = 1-0.3 = 0.7
p² = YY = (0.7)² = 0.49
2pq = Yy = 2 * 0.7 * 0.3 = 0.42
