(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.
<span>Professor Kwang Jeon observed that some amoebas in his invaded amoeba colonies survived thanks to changes made by the invading bacterias. This comfirmed the endosymbiotic theory that organells are formerly invading free living prokaryotes forms that were integrated and swallowed by others to form a new living unit.</span>
Humans controlled the flow of water, which reduced the water, and organisms lost habitats and food sources. Option A
<h3>What is a wetland?</h3>
The term wetland refers to a marsh area. It is an area that appears to be waterlogged al the time. It is home to various thriving species of living things that only survive in such a habitat.
The manner in which human activities have been affecting the Everglades is a wetland ecosystem in southern Florida is that humans controlled the flow of water, which reduced the water, and organisms lost habitats and food sources.

Answer:
Polarity and Non-polarity of molecules depend upon the electronegativity. The theory of electronegativity lies in entire inorganic chemistry. The more electronegative an atom, the more it seeks electrons. If one atom is more electronegative than others, it can form an ionic bond or a polar covalent bond.
