Why is there not much life on the deep ocean bottom?

2 answers:

5 0

Because the lack of oxygen and the pressure is too much for most fish/other things. Professional deep diver usually don't go under 400 feet. The deepest any man has gone is James Cameron, he went 35,756 feet (10,898 meters) below the sea level. The deepest point in any ocean is the Challenger Deep in the Marianas Trench it is 36,070 feet (10,994 meters) deep

Because there is a lack of oxygen that deep. The vast majority of deep-sea life has no air pockets.

The lock-and-key mechanism refers to

Zinaida [17]

The Lock-and-key mechanism was first proposed by Emil Fischer which described as the enzymatic reactions whereby an enzyme with a single substrate binds temporarily to form a substrate complex.
The lock-and-key mechanism is usually associated with the complementary shapes of an enzyme with a single substrate, wherein the lock that is being referred to is the enzyme and the substrate is the key. One right sized substrate (key) fits into the active site (key hole) of the enzyme (lock).
The active site which is mentioned above is structurally complementary to the substrate. This is the temporary binding site on the enzymes. Just like a lock and key, the enzyme as the lock and the substrate as the key is said to fit together.

More solar energy reaches the equatorial regions than the polar regions because the equatorial regions

crimeas [40]

The answer is that the equatorial regions receive sun rays closest to the vertical (direct rays) because of their position relative to the equator where the tilting of the earth only mildly affects the climate. The climate along the equator changes very little through out the year and has summer like conditions for most of the year.

However the other regions may receive direct sun rays but for far more limited periods. In the months of July and August (summer months), the northern hemisphere is tilted towards the sun and receives the most direct rays. The opposite occurs in December and January when it is tilted away from the sun and thus winter sets in, whereas the southern hemisphere is at this time tilted toward the sun and receives the most direct sun rays.
