When the stomach, small intestine, and large intestine work together to process food, they form a functional unit known as an organ system. Thus, the correct option is A.
An organ system may be defined as a cluster of organs that work together to perform a specific bodily function.
Here, the stomach, small intestine, and large intestine constitute an organ system known as the digestive system.
Therefore, the correct option is A.

Genetic variety slowly causes hundreds of species of beetles to form from a single species.
B)
A single antibiotic is able to quickly and easily kill millions of genetically identical bacteria.
C)
Millions of bacteria are quickly produced by cell division, in one afternoon in a jug of milk that has been left on the counter.

D)
Male anglerfish must live on larger females as parasitic mates, since they encounter other anglerfish so infrequently in the deep ocean.
Answer:
The correct answer would be B) A single antibiotic is able to quickly and easily kill millions of genetically identical bacteria.
Asexual reproduction results in the production of offspring which are identical to each other as well to the parent cell or organism. They are termed as clones.
Lack of genetic diversity makes them prone to the extinction.
As they all have identical genetic material, they become prone to same threats. For example, if one cell or organism is vulnerable to temperature change then the entire population can be extinct due to a similar change in the temperature.
Similarly, if a single antibiotic can kill one bacteria then it can kill the entire population due to their identical genome.
