Answer:
The pelagic zone refers to open and free waters in the body of the ocean that stretch between the ocean surface and the ocean bottom and are not too close to some boundary, like a shore or the seafloor or the surface.
Explanation:
The ducts empty the saliva from the submandibular salivary glands into the two sublingual carnicles.
The saliva produces in the salivary glands contains an enzyme named amylase, which is responsible for the chemical breakdown of starch. The saliva also helps to add moisture to the food and make it easier for it to pass through the ailementary canal. Further break down of starch then occurs when amylase is secreted into the small intestines.
Answer:
100% Wavy hair
Explanation:
The gene involved here codes for hair texture in humans. The alleles of the gene (straight, S and curly, s) exhibits incomplete dominance. Incomplete dominance is a genetic scenario whereby one allele does not completely mask the expression of the other allele, instead an intermediate phenotype that is heterozygous is formed.
In this case, a man with curly hair (ss) marries a woman with straight hair (SS). The children from this cross will all possess a heterozygous genotype (Ss) and be phenotypically wavy-haired, since Incomplete dominance is exhibited by the gene. Therefore, 100% of the offsprings/children will have wavy hair phenotype.
Answer:
A Punnett square for the following monohybrid cross can be shown as follows:
s s
S Ss Ss
S Ss Ss
a) The genotype of the potential offspring will be Ss, they will be heterozygous dominant.
b) There is a zero% probability that the offspring will have no freckles. As one of the parents was homozygous dominant for the freckles, hence all of the offsprings will have freckles.
