Answer:

Abyssal plain

Explanation:

Between 4000 to 6000 meters below the ocean, the abyssal zone exists which is salty (saltiness between 34.6 to 35 parts per thousand) and cold (temperature between 0 to 4 degree celcius)

Abyssal plain consists of uneven surface of oceanic crust covered by fine grain sediments such as clay and silt. They have major reserve of deep ocean biodiversity.

An abyssal plain is an underwater plain on the deep ocean floor, usually found at the depths between 3000 and 6000 m. Lying generally between the foot of a continental rise and a mid-ocean ridge, abyssal plains cover more than 50% of the Earth's surface. They are among the flattest, smoothest, and least explored regions on Earth.

When two hormones must be present to achieve full expression of an effect, that interaction is called ______________.
Vinvika [58]

Answer:

Synergism

Explanation:

Synergism means cooperation, and is a term of Greek origin (synergy). Synergy is a work or effort to accomplish a certain very complex task, and to be able to succeed in the end. Synergy is the moment when the whole is greater than the sum of its parts.

In physiology, synergism occurs when the effect of two or more combined chemical agents is greater than the sum of individual effects. Concerning hormones, synergism happens when two hormones must be present for the full expression of an effect. That is, two hormones act for a certain purpose.

Example: FSH (follicle stimulating hormone) and estrogen cause oocyte maturation, but this only occurs if neither acts in isolation.

Examples of ovoviviparous animal
stiv31 [10]

Answer:

sharks, rays, snakes, fishes, and insects

Explanation:

These ovoviviparous animals produce eggs, but instead of laying eggs, eggs develop inside the mother's body. The eggs are laid in the mother. After rocking, they stay in the mother for a while and feed there. Then the young are born live.

Ovoviparity is, therefore, a mixture of oviparous (animals that lay eggs) and viviparous (animals that develop in the mother’s body).

blsea [12.9K]

The person who is most likely to be interested in the research involving the transfer of energy by the organisms living in the ocean's hydrothermal vents is Everett Shock.

He along with his students tests and develops the thermodynamic data for the bio-molecules, minerals, and the aqueous solutes. The reactivity of the organic compounds is explored by them in the hydrothermal conditions. So, he is the most likely person to be interested in the said discovery.

Hence, the answer is 'Everett Shock'.
