When a single cell of e. coli reproduces, it first duplicates its dna. next, the cell elongates as each copy of dna is pulled toward opposite ends of the cell. the membrane then pinches inward, dividing the cytoplasm into two halves and producing two daughter cells. what is true about these daughter cells? a. they are genetically different from the parent because they are produced by asexual reproduction. b. they are genetically different from the parent because they are produced by sexual reproduction. c. they are genetically identical to the parent because they are produced by asexual reproduction. d. they are genetically identical to the parent because they are produced by sexual reproduction.

C. They are genetically identical to the parent because they are produced by asexual reproduction

Explanation:

E. coli is a popular species of bacteria, which reproduction by binary fission, a type of division similar to mitosis. The cell undergoes all normal procedures like DNA replication, actual division (binary fission) and cytokinesis to produce two daughter cells.

This process described is a form of asexual reproduction because it does not require a second partner for it to occur. It is a one organism process. Due to the fact that this process is quite similar to Mitosis, the two daughter cells are exact replica of the parents cell i.e. the daughter cells are genetically identical to the parent cell that divided as there is no room for genetic variation via asexual reproduction.

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.

the sun's light combined with the visible wavelenghts form what is called ultraviolet radiation, which are the long waves at the end of a visible light sprectrum.
