Answer:
Relaxation of the dartos muscle.
Explanation:
Testes are present in scrotum outside the pelvic cavity to maintain the temperature about 2-3 degrees Celsius below the body temperature as required for sperm production. Dartos muscle is the layer of smooth muscle located in the superficial fascia. The contraction of dartos muscle serves to make the skin of the scrotum wrinkled and tight.
During hot weather, the dartos muscle relaxes and makes the surface of scrotum less wrinkled to increase the loss of the heat from its surface. The increased heat loss from the surface of scrotum due to relaxed dartos muscles keeps the testes protected from heat.
The right answer is B. folding
The translation of the genetic information is done in two stages: one translates the sequence of the bases of the gene into amino acid sequence of the protein is the primary structure; the second translates this sequence into a complex, precisely defined three-dimensional structure, the only one able to confer on the protein its biological activity.
The second stage, or "protein folding", is at present one of the central problems of biological research.
Answer:
Avermectins
Explanation:
Avermectin is a class of drug that are used as a pesticide to kill the helminths. Averctin may exist in the form of monosaccharide as well as disachharide.
The averctin drug blocks the transmission of electrical impulse in the brain. This drug inhibits the neuromal transmission in helminths and thus proves to be a effective drug to kill the helminths.
Thus, the correct answer is option (2).
Stamen is composed of anther and filament. The pistil is composed of stigma, style, and ovary. ... The key difference between stamen and pistil is that stamen is the male reproductive organ which produces pollens of angiosperms while pistil is the female reproductive organ which produces ovules of angiosperms.
I hop this helps!
Photosynthesis occurs in the Chloroplasts.
The respiration takes place in the Mitochondria.
Hope this helps!! :)
