Answer:
Ocean surface winds play a vital role in the water cycle as the tropical Pacific Ocean and overlying atmosphere react with, and influence each other. Easterly surface winds along the equator control the quantity and temperature of the water that upwells (moves or flows upward) to the surface.
They are unicellular prokaryotes, that are lacking membrane bound organelles.
Answer:
30 calories of energy
Explanation:
In an aquatic ecosystem, zooplanktons are primary consumer i.e. they feed on primary producers e.g phytoplanktons. They are fed on by smaller fishes e.g tilapia, which in turn is fed on by sharks. Based on this, we have a food chain as follows:
phytoplankton → zooplankton → tilapia fish → shark
From this food chain, it appears that ZOOPLANKTON is a primary consumer while SHARK is a tertiary consumer. Since only about 10% of energy is transferred to each trophic level when organisms feed on one another, if there are 3000 calories of energy available at the zooplankton, the following will be available for sharks:
For secondary consumer = 10/100 × 3000 = 300 calories for tilapia fish
For tertiary consumer = 10/100 × 300 = 30 calories for shark.
Answer:
The correct answer will be option-D
Explanation:
Learned helplessness is defined as the psychological condition in which the person starts believing that the person is incapable of doing and accomplishing small tasks and has no control or lost control over the surrounding environment.
This condition happens when the person fails to escape the shocks caused by the aversive events and starts believing that the outcomes are independent of their response.
This condition is biological and is caused by the inhibition of the ventromedial prefrontal complex pathway associated with the learning ability. The ventromedial and also dorsal raphe nucleus is involved in the learned helplessness.
Thus, option-D is the correct answer.
