The answer is H. He is mechanically digesting his food.
Most of the cells in the human body are diploid.
Diploid is a cell or organism that has paired chromosomes, one from each parent. In humans majority of the cells are diploid and have 23 pairs of chromosomes. The exception are the human sex cells (egg and sperm cells). These contain a single set of chromosomes and are known as haploid.

Answer:
\rB. nutrients that are essential cannot be made by the body, so they must be obtained from food.
Explanation:
If we look at the definition of essential fatty acids, it clearly states that these are fats which human body cannot prepare but are essential for proper functioning of body. Since body cannot synthesize them on their own, therefore we must obtain them through a diet rich in them. Two main essential fatty acids are:
- Alpha-linolenic acid (omega-3)
- linoleic acid (omega-6)
They play essential functions in body sucg as :
Production of hormones
Better adrenal and thyroid activity
Regulation of inflammatory and immune responses, function and development of brain.
Supporting the development of healthy skin and hair.
Option B is the best option.
Hope it helps!
Thank you
Which mode of inheritance produces heterozygotes with phenotypes that differ from either homozygote but typically more closely resembles one homozygous phenotype than the other?"
A) complete dominance
B) incomplete dominance
C) codominance
D) epistasis
E) incomplete penetrance
Answer:
B) incomplete dominance
Explanation:
Incomplete dominance occurs when the dominant allele of a gene is not able to mask the expression of the recessive allele completely. This results in the expression of a phenotype in the heterozygous genotypes that differ from both homozygous genotypes. However, the phenotype of the heterozygote is closer to one of the homozygous genotypes.
For example, the petal color in four o'clock plant is controlled by a gene with two alleles R and r. Here, the "R" allele can not produce enough pigment in heterozygous conditions to completely mask the expression of the "r" allele and the phenotype of the "Rr" plant is "pink". On the other hand, the phenotype of "RR" plant is red while that of the "rr" plant is "white".
