Answer:
Option B, Tinea capitis
Explanation:
Superficial fungal infection of skin of head or scalp is known as Tinea capitis.
These fungal infection attack the hair shafts and follicles and is a superficial form of mycosis or dermatophytosis.
Tinea cruris is the superficial infection of genitals, buttocks and inner thighs regions. Hence, option A is incorrect.
Tinea pedis is the superficial infection of foot and regions between the phalanges. Hence, option C is incorrect.
Tinea corporis is the superficial infection of arms, legs or skin. Hence, option D is incorrect.
Thus, option B is correct.
Answer:
Due to the cost and resource input (specially the land) required for producing ethanol
Explanation:
In current time most of the ethanol is produced by fermenting corn, sugarcane or other plants at high temperature. In this process of fermentation, liquid bio fuel is produced.
These plants and crops require large area for cultivation and production along with huge inputs of fertilizers and water. As per an estimate , 3 gallons of ethanol require bushel of corn that intakes 800 gallons of water which is a huge cost to any nation or individual
Hence, scientist are finding new ways to create ethanol
They lose water by evaporation on their skin and respiratory surfaces
The answer is tropical areas. The tropical areas obtain more
radiant energy from the Sun than they lose to space through terrestrial
radiation, and vice versa for polar areas. Earth has an energy remaining in the
tropics and an energy scarcity for the polar areas.
The responses observed in type IV hypersensitivities result from the action of T cells and phagocytes.
Hypersensitivity IV type, also called delayed-type hypersensitivity (DTH), involves T cell-antigen interactions that cause activation and secretion of cytokines. This type of hypersensitivity requires sensitized lymphocytes that respond 24–48 hours after exposure to soluble antigens. A type IV hypersensitivity reaction is a cell-mediated reaction that can occur in response to contact with certain allergens, resulting in what is called contact dermatitis, or in response to certain diagnostic procedures such as the tuberculin skin test. Certain allergens need to be avoided to treat this condition. Type IV hypersensitivity response is observed results from the action of T cells and macrophages while other types are mediated by antibodies. This reaction occurs at least 1–3 days after the initial exposure. Type IV hypersensitivity is the mechanism of many autoimmune disorders.
