Number one is B also number 2 is also B because I did it before
Answer:
A prostaglandins
Explanation:
Fever is the abnormal body temperature that is caused by pyrogens.Pyrogens are the chemicals produced by pathogen. Fever is protective mechanism of body to fight against pathogens. It is actually the immune response that spread to whole body with elevated temperataure. The elevated temperature helps to deal with pathogen more efficiently.
The interleukins released be immune cells in response pyrogen ultimately lead to release of prostaglandin E2. Prostaglandin E2 reset the hypothalamus thermoregulation. The hypothalamus feels the body temperature is cool although how high is the body temperature.
Explanation:
The uneven warming of the earth surface causes land and sea breeze over the land and water.
Water has a very high specific capacity and it takes more heat to cause a fractional increase in its temperature. During day, the air around water is cold and dense and under high pressure.
The land adjacent to the water, is a better conduct with a low specific heat capacity. When warming of the earth starts by the sun, the air on land heated by heat radiated from the surface. Air on land is warm, less dense and light.
This forces the air on land to move seaward and the cold air from the sea to move land ward and a sea breeze is set up.
At night the reverse is the case. The land loses heat very fast and the air around it is cold and dense. The water body does not lose heat so fast and the air around is warm and lighter. Air from the land replaces that on the surface of water and a land breeze is set up

Answer: The correct option is A.
Biosphere and ecosystems
Explanation:
This is because Biosphere and ecosystems include non living things and biosphere is the layer of the ecosystem that consist of both living and non living things.
Ecosystem consist of a area which consist of living things like plants, animals e t.c interacting with the non living part of the environment I e physical part which include temperature, soil e.t.c.
