Answer:
The correct answer is B respiratory system
Explanation:
Respiratory system of our body play a significant role in the inhalation of oxygen into and exhalation of the waste product known as carbon dioxide from our body.
Respiratory system basically composed of diaphragm and respiratory muscles.The volume of diaphragm increases during inhalation and decreases during exhalation. This is called the elastic nature of lungs which helps in efficient gas exchange.
Answer:
Pyruvate is turned to lactate via a process called fermentation
Explanation:
Pyruvate is the product of the initial stage of cellular respiration called GLYCOLYSIS. Pyruvate is produced in the cytoplasm where glycolysis occurs. The fate of pyruvate i.e. what will eventually happen to pyruvate, is determined by the presence or absence of oxygen.
In the absence of oxygen i.e. anaerobic condition, pyruvate is converted into lactate in a process called FERMENTATION. The NADH produced during glycolysis is reoxidized to form NAD+ in the process.
I believe the developing Sertoli cells are responsible for influencing the development of male reproductive structures through the production of anti-mullerian hormone. During embryonic development there is a sexually indifferent stage in which the embryo has the potential to develop either male or female structures. The sertoli cells produce Mullerian inhibiting substance, a peptide hormone that causes the mullerian ducts to regress.
