Answer:
These organelles are contractile vacuoles
Explanation:
Contractile vacuoles are intercellular pumps that are slowly filled with fresh water and eventually expel their contents outside the cell. Freshwater protists maintain the hydric equilibrium by contractile vacuoles that pump out the water of the cell and thus prevent the cell swelling induced by osmotic stress.
Adults of species in the order <u>Coleoptera</u> have 2 wings and the greatest variety of mouthparts.
<h3>Order Coleoptera</h3>
The coleopterans, (order Coleoptera), consist of the beetles and weevils. It is the largest order of insects.
They have two pairs of wings:
- One of the pair is the hard-shelled outer wings known as the “elytra”. These are not used for flying, but to protect the beetle's flying set of wings and its body as it crawls through narrow passages and tunnels in a tree.
- The second set of wings is membranous and is folded under the elytra when not in use.

The statement which best describes artificial selection as compared to natural selection is: C. In artificial selection, the passing on of traits is determined by human choice.
<h3>What is artificial selection?</h3>
An artificial selection can be defined as a process that typically involves human beings breeding living organisms such as <u>animals</u> and <u>plants</u> to favor a desirable characteristic or trait.
This ultimately implies that, the passing on of traits or characteristics is generally determined by human choice in artificial selection rather than in natural selection.
