(A) Protozoa and some low-level multicellular animals There are no organs responsible for excreting liquid waste. Such waste can penetrate the cell surface directly into the water outside of it. If paramecium does not contain vacuoles will cause it to lose the balance of body fluids The contractile vacuole compression rate depends on the osmotic pressure of the water in which the animal lives, i.e. the compression rate decreases. if the osmotic pressure of the water in which it resides increases But it will speed up if the osmotic pressure of water decreases.
(B) The water mixed with salt has a higher concentration than fresh water. So the water diffuses into the paramecium. Therefore, the contractile vacuole is less compressed to remove water from the cell than when in fresh water.
The answer to the question stated above is letter D. more;higher.
Clouds act in much the same way as high humidity in Earth's atmosphere. The presence of clouds means moist, humid, atmospheric conditions. This promotes<span> greater (more) heat retention, and higher nighttime temperatures, than on a clear, dry night.

Answer:
Water along with Carbon dioxide are essential for the process of Photosynthesis. Transpiration, the loss of water through stomata creates what is known as the Transpiration pull. This force enables a continued supply of water for photosynthesis, and distribution of nutrients to the plant for growth and maintenance.
The answer is (1.) entering the torpor
The hummingbirds are the tiniest bird in the world but is
also the biggest eater. They burn food so fast they often eat up to 3 times
their weight. They feed on nectars and insect. When they can’t eat especially
on cold temperatures, these birds go in a sleeping state called torpor. A
fascinating way to conserve energy.
