Answer:
As somatic cells are diploid (2n) 2n=56
gametes receive only haploid set so, n=28
Answer:
regulation of the diameter of blood vessels and control of blood pressure
Explanation:
Skeletal muscles are the multinucleated muscles with striations and are attached to the bones (skeleton). The main function of skeletal muscles is to generate the voluntary movement of the body or body parts. The skeletal muscles of face, rectum, and urinary bladder generate their voluntary movement as per the will of the organism. On the other hand, blood vessels are lined with smooth muscles with spindle-shaped cells.
For example, the muscles present in the subcutaneous layer of the skin of the face are responsible for various facial expressions. Contraction of these facial muscles brings about the movement of skin of the face to generate a wide variety of emotions. Smooth muscles of blood vessels are involuntary in nature.
Vasodilation and vasoconstriction as brought about by smooth muscles of blood vessels are regulated by the autonomic nervous system. Under the conditions of lower blood pressure, contraction of smooth muscles of blood vessels restore the reduced blood pressure. On the other hand, when the blood pressure rises above the normal range, the smooth muscles of blood vessels relax to dilate them and to lower down the blood pressure.
Answer:
iron, zinc, iodine, fluoride, selenium and copper.
The answer is phenotypes.
Phenotype is the physical characteristics of an organism which are the result of interaction between genotype and environment. <span>Genotype is the entire set of genes in the organism. </span>Genes have alternative forms called alleles which can be the same or different at one locus. No matter if they are different, they have the same function but give different physical characteristics. Knowing the genotype can help predicting the phenotype. For example, if we know which genes determine the eye color and know someone's genotype, it is easy to predict if someone will have blue or brown eyes.
Answer:
The correct answer is option c). "Defective enzymes result in the accumulation of potentially toxic substances".
Explanation:
Lysosomal storage diseases (LSDs) are a group of rare metabolic disorders that have a genetic influence and are, most of time, autosomal recessively inherited. The molecular basis of the diseases are an accumulation of potentially toxic substances due to the presence of defective enzymes. In fact, LSDs are often triggered by a single defective enzyme that is required for lipids metabolism.
