When the comb jelly, mnemiopsis leidyi, was introduced into the black sea, its population exploded to 500 comb jellies per cubic yard in 1988. the jellies devoured all the zooplankton and fish larvae, drastically reducing the numbers of the native fish populations. this situation demonstrates .the difference between biotic and abiotic factors in an ecosystem. b.effects of local evolution or migration on an ecosystem. c.the impact of removing or adding organisms to an ecosystem. d.the types of interactions between organisms in an ecosystem. select the best answer from the choices provided

Seen in some gram-positive bacilli, occurs when only the inner portion of a cell wall is deposited across the dividing cell. this new cross wall puts tension on the outer layer of the old cell wall. eventually, the outer wall breaks at its weakest point with a snapping movement that tears it most of the way around. the daughter cells can then remain hanging together almost side by side being held by a small remnant of the original outer wall. choose from the following statements the ones that correctly discuss reproduction using binary fission in a bacterial cell. select all that apply. view available hint(s) select all that apply. due to the stretching of the cytoplasmic membrane, both cells will contain a complete genome. each daughter cell will contain an equal number of organelles. the daughter cell will be a permanently smaller copy of the mother cell but will contain a complete genome. each daughter cell is an exact copy of the other, both genetically and morphologically
