Answer:
There is no diagram but the question can be answered using the description. The options to this question are:
Which is the genotype of the sweet pea?
A.heterozygous dominant
B.heterozygous recessive
C.homozygous dominant
D.homozygous recessive
The answer is C (homozygous dominant)
Explanation:
According to the question, a flower colour gene in a pea plant possesses two different alleles, P and p. Lettercase is used to illustrate that allele P (upper case) is dominant over allele p (lowercase) i.e P will be expressed over p in the flower colour gene.
According to the question, the pea plant exhibits a purple flower colour and is labelled as PP. This genotype is said to be homozygous because the same alleles (P) make up the plant's genotype. Since the allele P coding for purple coloration is dominant, the purple sweet pea is said to be HOMOZYGOUS dominant i.e. possess the same dominant alleles for that gene.
Answer:
All systems work together to stabilize the body.
Explanation:
Certain systems work with each other in order to maintain homeostasis, which is essential for the body. For example, when blood circulates through the digestive system, it picks up nutrients absorbed by the body during its last meal. Additionally, blood carries oxygen taken in by the lungs. The circulatory system works with the respiratory system here to distribute oxygen to other parts of the body.
Answer:
carbon is recycled in the biosphere. cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.
Explanation:
Answer:
Their winter habitat has no bearing on their degree of reproductive isolation.
Explanation:
The two species of sparrows breed only during spring and summer and it has been given that during this time the species live separate from each other. Hence they do not breed with each other.
It is in winter that they live together but this season is not the breeding season. They only feed and prepare for the upcoming breeding season during this time hence the winter habitat has no effect or bearing on their degree of reproductive isolation.
Reproductive isolation only comes into play during summer and spring where they show prezygotic isolating mechanism. They live far from each other thus show habitat isolation due to which they do not mate with each other.
40. I remember this by knowing that haploid is like half and diploid is like double
