Cell membrane is a thin line.it controls the movement of materials into and out of the cell. it is partially permeable,that is,it allows only certain materials to pass through.
Answer:
The correct answer will be- ADH alters the reabsorption of water and RAAS leads to the reabsorption of sodium ions.
Explanation:
To maintain the osmolarity of the blood in the human body, the body activates the RAAS pathway and the production of ADH.
RAAS pathway gets activated when the receptors sense low blood pressure in the body. This activates the production of renin from the juxtaglomerular cells of the body which converts the angiotensin to angiotensin I and later angiotensin II.
This allows the reabsorption of sodium ions in the blood through proximal and distal tubules in the nephron. This activates the synthesis of aldosterone which increase the permeability to sodium ions.
The Antidiuretic hormone helps regulate the low blood pressure by adding aquaporins to the distal tubule membrane which help absorb the water.
Thus, ADH alters the reabsorption of water and RAAS leads to the reabsorption of sodium ions is the correct
Flowering plants are the most successful land plants because theri seeds are protected in fruits
Answer:
1. As temperature and pressure increases, density increases
Explanation:
The earth is composed of three main layers: Crust, Mantle and Core. The density or mass per unit volume of the earth's layers increases as one moves from the surface towards the interior of the earth known as the core. Also, there is an increase in pressure and temperature as depth increases. There are three main sources of heat in the earth's core: (1) conserved heat from when the planet formed and coalesced, (2) heat due to friction caused by denser core material sinking to the center of the planet, and (3) heat from the decay of radioactive elements.
The earth's core is composed almost entirely of the metals, iron and nickel. The core has an inner solid layer and a molten outer core. Iron and nickel are both very dense metals, so the core of the earth is very dense and the density increases with depth with the inner core being the most dense layer of the earth.
