Skin remains red after a bad sun burn because:
inflammation causes increased blood flow.
Explanation:
When our skin is exposed to sun rays , the epidermal layer starts getting damaged. The damage to the cell caused by sun rays triggers the melanin secretion. Increased secretion of melanin results in darkening of the exposed region .
However, the damage and inflammation to the skin increases blood flow to the skin, this causes reddening of the skin.

Answer:
D) elastic cartilage
Explanation:
Cartilage is a connective tissue which is fibrous in composition which provides its physical properties like the softness, elasticity and strength.
There are three types of cartilages- the elastic, hyaline and the fibrocartilage. Among these three the cartilage which forms the external ear is the elastic cartilage. The elastic cartilage is composed of the elastin protein, type II collagen and the elastic fibres. The presence of the elastin proteins and fibres allows the ear to be an elastic organ.
Thus, Option-D is the correct answer.
Answer:Fossils are all throughout different rock layers. The oldest fossils are on top and the newest are at the bottom.
Explanation: there is a rich fossil record that shows the evolutionary transitions from horse ancestors to modern horses that document intermediate forms and a gradual adaptation o changing ecosystems.
1. Osmosis is a process which occurs when there is a difference in solute concentration between two solutions separated by a semipermeable membrane.
2. Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane. It is also defined as the measure of the tendency of a solution to take in pure solvent by osmosis.
3. The semipermeable membrane limits the diffusion of solutes in the water.
4. In an isotonic solution, the flow of water in and out of the cell is happening at the same rate. ... Water moves into and out of cells by osmosis.
5. Osmosis is basically diffusion with water. ... The most common example of facilitated diffusion is the movement of water across a cell membrane through transmembrane proteins, which requires no energy. They are simply powered by the concentration differences of the molecules between the two sides of the cell membrane.
(Hope this helped. Have a nice day.)
