What effect would an increase in venous tone have on mean arterial pressure?

Biology

An expansion in venous tone will increment heart yield and increment mean blood vessel weight. All blood vessel and venous vessels under basal conditions display some level of smooth muscle compression that decides the breadth, and thus tone, of the vessel.

Which part of the cell is affected by the movement of molecules through diffusion, osmosis and active transport?
kolezko [41]

Ans.

Diffusion, osmosis, and active transport are mechanism of cellular transport that involves movement of molecules through plasma membrane. Diffusion shows movement of small, hydrophobic particles without the help of protein molecules through cell membrane along the concentration gradient.

Osmosis involves movement of water molecules against concentration gradient (from an area of high solvent concentration to an area of low solvent concentration) through cell membrane.

Active transport shows movement of particles, against the concentration gradient, means from a region of higher to lower concentration of molecules through cell membrane. It involves transport through membrane proteins.

Thus, the part of cell, which is affected by the movement of molecules through osmosis, diffusion, and active transport is cell membrane or plasma membrane.

In the fluid-mosaic model of the plasma membrane, the phospholipid molecules are oriented so that the _____________ heads are fa
saveliy_v [14]

Answer:

Hydrophilic heads facing exterior

Hydrophobic tails facing interior

Explanation:

In 1972, the fluid mosaic model was proposed to describe the structure of the plasma membrane. This model describes the plasma membrane to possess components including phospholipids, cholesterol and proteins. The phospholipid component is composed of glycerol, two fatty acids and a phosphate-containing head, which are arranged in two adjacent layers forming the phospholipid bilayer in the membrane of biological organisms.

Phospholipids have both the hydrophilic and hydrophobic region. Hence they are said to be AMPHIPATHIC.

The head of the phospholipid is negatively charged due to its phosphate content, making it polar and hydrophilic i.e. water-loving. This hydrophilic head faces the exterior of the cell in order to interact with fluids.

The tails of the phospholipid are long fatty acids that keep away from water i.e. hydrophobic. Due to their water-fearing nature, they avoid water and face the interior of the cell, where each tail face each other.
