Aldosterone stimulates the reabsorption of Na+ and secretion of K+ in the the kidneys. Aldosterone is classified as a steroid hormone that is being produced and secreted in the adrenal cortex. It stimulates the reabsorption of these ions by increasing the activity of the sodium and potassium pumps and the leakage channels of the sodium and the potassium ions. This hormone would activate the electrogenic channels of these ions located in the apical membrane increasing the synthesis of the channels. The secretion of this hormone is being stimulated by the low plasma sodium ion concentration, high plasma concentration of the potassium ions and the angiotensin 2.
Answer:
Ovary
Explanation:
Anthophyta or the angiosperm are the plants which bear reproductive structure in a colorful modified shoot called flower.
The flower contains both male and female reproductive structures. It is the female reproductive structure that develops into the fruits when the female egg cell is fertilized with the sperm.
The female reproductive structure is made of the style, stigma and the ovary. The ovary encloses the egg cell which after fertilization becomes an embryo and the ovule turns into the seed and the ovary turns into the fruits. That is why the fruits bear the seeds.
Thus, the ovary is correct.
Answer:
O sinkholes, caves, and hot springs chemical and physical actions of groundwater.
Explanation:
Sinkholes, caves, and hot springs are formed from the actions of groundwater. The rock is made up of lime below the surface of sinkholes. These lime react with underground water and dissolve it which soften the rock and causes sinkholes. Caves are also formed when the water dissolve the limestone present in the rocks of the cave and slowly the degradation of rock will occur and caves are formed. Hot springs are formed when the groundwater is heated by the magma of the earth crust.
