Answer: population of bacteria can survive and flourish by using light independence reactions
Explanation: So like the bacteria perform chemical reactions which produce energy for them
Some of these can easily be eliminated by knowing that both nitrogen 14 and nitrogen 15 are isotopes ( same element, with the same amount of protons, but with different numbers of neutrons) of nitrogen. So if the only difference between nitrogen 14, 15 , and regular nitrogen is the amount of neutrons...how many protons and electrons should both nitrogen 14 and 15 have? After thinking, you should be able to eliminate A, B,and C.
"Gas bladders" and lungs are similar organs, although they serve different functions.
Both of them develop from a location in the upper throat i.e. the pharynx and are used to manipulate gases. They both contain a good blood supply.
However, the lung is used for breathing and is often found in land vertebrates, while on the other hand, the gas or swim bladder is used in the regulation of buoyancy and the latter is found in all other bony fishes e.g. perch.
Perch use the swim bladder to control their buoyancy by filling it with oxygen from their gills using a gland, which is known as a gas gland. This expands the bladder, thereby pushing the fish toward the surface of the water.

The short segments of newly assembled DNA from which thelagging strand is built are calledOkazaki fragments. As replication proceeds and nucleotides are added to the sugar end of the Okazakifragments, they come to meet each other. The whole thing is then stitched together by another enzyme called DNA ligase.
*Genetic determinism of sexes
*Two types are known.
