Answer:
The correct answer is A. Effectively, aldosterone is synthesized from cholesterol.
Explanation:
Aldosterone is a steroid hormone from the mineralocorticoid family, synthesized in the glomerular area of the adrenal cortex of the adrenal gland. It acts in the conservation of sodium, in the secretion of potassium and in the increase of blood pressure. Its secretion is decreased in Addison's disease and increased in Conn's syndrome. Aldosterone, as well as all steroid hormones, is synthesized from cholesterol.
Answer:
The correct answer would be A. crust.
The crust is the outermost layer of the earth which is composed of different types of rocks such as sedimentary, metamorphic, and igneous rocks.
It is completely solid and can be broadly classified into two types: continental crust and oceanic crust.
The thickness of the oceanic crust is about 5 km to 10 km. It is primarily composed of basalt, gabbro, and diabase.
The thickness of the continental crust is around 30 km to 50 km.
The crust forms lithosphere along with hard and upper mantle.
The physical processes on Earth create constant change. These processes—including movement in the tectonic plates in the crust, wind and water erosion, and deposition—shape features on Earth's surface.
