The human reproductive system is regulated by the endocrine system.
Answer: Option C) Root hairs have an elongated shape that increases the surface area-to-volume ratio.
Explanation:
The larger surface area-to-volume ratio of root hairs enables them to rapidly absorped water molecules and nutrients along their elongated shape while aiding their upward transport from the root up the shoot (through the xylem vessels).
Answer:
<em>The genotype of the plant will be PpSs and the phenotype will be purple colour and smooth shaped. </em>
Explanation:
Considering the description in the question, we know that purple colour is dominant over the yellow colour and smooth shape is dominant over the wrinkled shape.
A homozygous trait can be described as a trait which arises due to the same alleles of a gene. A heterozygous trait arises when both the alleles of a gene are different. In such a case, one allele will be dominant over the other one and the phenotype of the dominant allele will be seen in the plant. As purple colour and smooth shape are dominant traits, hence they will be seen in the heterozygous plant.
