Why does your skin remain red after a bad sunburn? a) Blisters form, lifting the epidermal layer. b) Inflammation causes increased blood flow. c) Loss of sweat glands in the dermal layer d) Damaged epidermis cells are sloughed off.'

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.

then that particular organisms become extinct.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
