Which statement correctly explains how marine garbage impacts biodiversity in a marine ecosystem?

a.) animals use it as nesting material and it is toxic to their young.
b.) as the plastic biodegrades, it produces chemicals that can increase reproduction rates.
c.) it is often mistaken as floating food and is harmful after being ingested.
d.) many organisms fear the floating plastic, so they migrate to other areas.

C.) It is often mistaken as floating food and is harmful after being ingested.

Explanation:

The floating plastic in the marine garbage can impact the biodiversity in a marine ecosystem. As, the plastics may be eaten along with the food by the marine animals. Plastic being a non-biodegradable material will remain undegraded in the marine water body as well as in the digestive system of the marine animals. Hence, will result in mortality of the marine animals. This will lead to decline in biodiversity of the marine ecosystem.    

i have to report this, it doesn't relate to biology

a researcher conducts an experiment on the secretion of a particular hormone in mice. scientists inject mice with a substance that stimulates the production of the hormone. the scientists then test the levels of hormones produced by the mice. the tool used to measure the hormones consistently detects the levels at 10 points lower than the actual hormone levels in the mice. this tool makes measurements, but the measurements aren't .
