Inhibin B is produced in the testis, principally by the Sertoli cells. There are temporal changes in inhibin expression and secretion with the changing role of the Sertoli cell in immature and adult testes. Variations in inhibin B production between species reflect the different patterns of maturation.

electromagnetic spectrum, the entire distribution of electromagnetic radiation according to frequency or wavelength. Although all electromagnetic waves travel at the speed of light in a vacuum, they do so at a wide range of frequencies, wavelengths, and photon energies. The electromagnetic spectrum comprises the span of all electromagnetic radiation and consists of many subranges, commonly.

Explain how sound is produced by your school bell ? class-9 sound 1 Answer 0 votes answered Oct 18, 2019 by Divinan (66.1k points) selected Oct 18, 2019 by Bhuvan01 When the school bell is struck with a hammer, it starts vibrating (or moving back and forth rapidly through a very small distance). The vibrating school bell products sound.

The principal action of ADH is to regulate the amount of water excreted by the kidneys. As ADH (which is also known as vasopressin) causes direct water reabsorption from the kidney tubules, salts and wastes are concentrated in what will eventually be excreted as urine.

Alcohol has anti-anxiety and anti-stress properties. However, alcohol acts as a central nervous system depressant, so too much drinking darkens your mood. "It does hijack (our) neurocircuitry and.

Hydrochloric acid when added to a reactive metal like sodium, potassium etc. Hydrogen gas is evolved. When iron metal reacts with dilute H 2 SO 4 , iron sulphate is formed with the evolution of hydrogen gas.

Ambulances etc have a revolving light. It is also called a "flashing light" The sound is a siren. When you hear a siren or see flashing lights from an ambulance or fire engine, if they are following you, you must slow down and pull over. I'm not sure what you mean by "verb that expresses it" I suppose an ambulance driver might "turn on" the siren.

When oxygen is available, the pyruvate molecules will then be converted to acetyl CoA which enters the mitochondria and enters the citric acid cycle. Both glycolysis and the citric acid cycle produce a small amount of ATP (2 ATP per pathway), but the majority of the ATP produced by aerobic metabolism is achieved when the products of glyolysis.

Key Points The steam engine was one of the most important technologies of the Industrial Revolution, inspiring other innovations and initiating further technological advancements. In 1775, James Watt formed an engine-building and engineering partnership with manufacturer Matthew Boulton.
