The inter-tidal zone refers to an area that is under water during a high tide and exposed to the air at low tides. Organisms living in the inter-tidal zone must be adapted to living in an extreme environment. They must be able to survive for sometime without water and in water that can be high or low in salinity. The nearshore zone is always under water and is the area where waves can break in their approach to the shore. Organisms here are adapted to living completely submerged in water.
Answer:
-The ATP provides the energy, and the NADPH supplies the electrons for the Calvin cycle, which converts carbon dioxide to sugar. The ADP and NADP+ that result from the Calvin cycle shuttle back to the light reactions, which regenerate ATP and NADPH.
Explanation:
<span>Human skin is one of the more important cooling systems. Unlike many other mammals, humans have sweat glands. These cool the surface of the skin by evaporating water. Body heat is carried to the surface of the skin by the circulatory system. Humans also have finer hair than other animals. We are actually as hairy as chimpanzees, but our hair is so fine it makes us appear to have none. This lack of dense hair allows the skin to evaporate sweat more efficiently. Another human cooling mechanism is our posture. Walking upright means only a small portion of the body is exposed to direct sun during the hottest part of the day. Our ancestors were thought to scavenge during this period because preditors had to escape the sun. Walking on 4 legs meant the entire surface of the back was exposed to the sun.A uniquely human adaptation to heat is the scalp. Blood vessels run directly from the surface of the brain through pores in the skull and out across the head and face. This serves to cool the brain. Humans have enromous brains which generate quite a lot of heat. This system of veins serves like a kind of radiator, keeping the brain from overheating. It also explains why head injuries tend to bleed so profusel</span>

Answer:
False
Explanation:
Humans:
Nitrogen is represented by the symbol N. It is abundant in the environment but humans can't use it directly from air or soil but depends upon green plants and microbes to convert it in to the usable form for using it
Plants:
Plants do not get their nitrogen directly from the air. Although nitrogen is the most abundant element in the air, every nitrogen atom in the air is triple-bonded to another nitrogen atom to form molecular nitrogen, N2
