Answer:
D. Ticks live on and drink blood from a cow.
This is an example of parasitism, where the ticks (parasite) are living off of the blood of the cow, the host animal.
Explanation:
Parasitism is a relationship between organisms. In this relationship, one organism (parasite) lives on or in another organism (host) and gains benefits from the host, causing it some harm.
Parasites are classified as ectoparasites, which live on the body surface of the host (ticks, fleas, leeches, and lice) and endoparasites, which live in the body of the host. Endoparasites are either intercellular, which live inside the host’s body (round worms, tapeworms) or intracellular, which live inside the cells in the host’s body (bacteria or viruses).
Parasites help to control dominant species and has a role in evolution by transferring genetic material between species.
The correct answer is - A. coal.
The coal is classified as organic sedimentary rock because the basis for its formation is the organic matter. It is a rock that is formed on the basis of dead organic matter from the Carboniferous, mostly of trees that existed in this period. Over a long period of time, tens and hundreds millions of years, the coal, under all the temperature and pressure that had influenced it started to take the shape in which we now know it. It can be mixed with other material, but in general comes in the non-mixed organic based form.
