Answer:
Complete dominance Result from successive mutations of the same GENE.
Explanation:
The epimysium
each muscle is surrounded by a connective tissue sheath called the epimysium fascia, connective tissue outside the epimysium, surrounds and separates the muscles.
Answer:
The correct answer is option d, that is, it prevents the enzyme, which degrades cyclic GMP.
Explanation:
Oral therapy for erectile dysfunction is Viagra, which is the citrate salt of sildenafil, it works by preventing a specific phosphodiesterase type 5 or PDE5, which is the inhibitor of cGMP. During sexual stimulation, nitrous oxide is released in the corpus cavernosum causing the erection of the penis in males. The nitrous oxide then stimulates the enzyme guanylate cyclase that further makes the concentration of cGMP to elevate, this generates smooth muscle relaxation in the corpus cavernosum and permitting blood the inward flow of blood.
Viagra works by increasing the influence of nitric acid by preventing PDE5, which is accountable for the deprivation of cGMP in the corpus cavernosum. At the time of sexual stimulation, the discharging of nitrous oxide takes place, the viagra inhibits PDE5 causing the levels of cGMP to elevate in the corpus cavernosum leading to smooth muscle relaxation and continuous flow of blood to the corpus cavernosum.
Answer: Duplication of chromosome can cause multiple genes to work in an uncontrolled manner.
Explanation:
There are numerous genes that are encoded by the chromosome. The duplication in the chromosome can cause multiple genes to go out of control that can cause patterning of the body and head which can influence the wing patterning or pigmentation. For example in Down's syndrome the three copies of chromosome number 21 are formed which is the trisomy of chromosome number 21 which can cause developmental issues in humans symptoms are flattened face, short neck, small ears, and others.
