Answer:
It's MITOSIS.
Explanation: We are also learning about this in class.
During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. Mitosis itself consists of five active steps, or phases: prophase, prometaphase, metaphase, anaphase, and telophase.

Answer:
The correct answer is ''it leads to respiratory alkalosis.''
Explanation:
Respiratory alkalosis is defined by pH values> 7.45, and is characterized by an increase in pH and a decrease in pCO2. The most frequent cause is alveolar hyperventilation. Alveolar hyperventilation causes respiratory alkalosis, presenting a decrease in ionic calcium and in some cases tetany. To compensate for this increase in pH, renal HCO3 excretion is increased, but this process requires 24-48 hours. Respiratory alkalosis - primary or compensatory - is defined by hypocapnia, a finding that involves alveolar hypoventilation. The symptoms of acute respiratory alkalosis, the "hyperventilation syndrome," vary only in intensity from those of any alkalosis - most notably disturbances in neuromuscular function (eg, paresthesias, tetany, tremor). A constellation of symptoms have been described with respiratory alkalosis, including increased intracranial pressure, decreased consciousness, tachycardia, hypertension, carpopedal spasm, anxiety, dizziness, and a feeling of vertigo.
Answer:
The left and right atrium
Explanation:
The heart has four chambers: two atria and two ventricles.
The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle.
The right ventricle pumps the oxygen-poor blood to the lungs.
The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle.
The left ventricle pumps the oxygen-rich blood to the body.
Answer:
The most important hormone involved in controlling sperm production is a steroid called testosterone. This is produced in the testis itself, by the Leydig cells (see Figure 12a). The testosterone is released from the Leydig cells between the tubules, and taken up by the neighbouring Sertoli cells.
