Answer is hypertonic.
The ability of an extracellular solution to make water move into or out of a cell by osmosis is known as its tonicity. Tonicity is concern for all living things, especially in in organisms lacking cell wall, <em>Paramecium</em> is one such protozoan. It has specialized structures called contractile vacuoles. A contractile vacuole collects excess water from the cell and release it out, keeping the cell from lysing as it takes on water from extracellular environment which hypotonic (a lower osmolarity than the cell’s cytoplasm) as compared to hypertonic environment inside <em>Paramecium</em>.
Answer:
Structures that are still present but currently serve little to no purpose
Explanation:
<em>Vestigial structures/organs are general defined as structures/organs that are present but poorly developed without any functional use in the present living organisms but thought to have been fully developed and functional in their ancestors.</em>
Fully developed and functional organs gradually become less developed and non-functional across generations as the environment keeps changing and organisms found lesser use for the organs. An example includes the <u>caudal vertebrae</u> found in man which is kind of useless but thought to have been fully developed and functional in the ancestors of man - the monkeys.
<u>Vestigial organs are often used as one of the morphological evidence of the evolution of living organisms.</u>
Answer:
Hi there, the answer is energy
Explanation:
Carbon dioxide, oxygen, and water are all products of cellular respiration in fact carbon dioxide and oxygen are extremely important for ATP. If you are talking about aerobic respiration oxygen is the main product for it because it reacts to glucose. The only thing that isnt part of the product of cellular respiration is energy. After ATP is created for the plants it makes its own energy afterward.
Hope this helped :)
