Intrusive igneous rocks include gabbro, granite, and diorite. Each rock differs in that it was created by a separate silica-containing magma.
Despite having different silica concentrations, granite, diorite, and gabbro are all products of magmas. Gabbro is a typical rock that contains 45% to 55% silica. With a silica content ranging from 55% to 65%, diorite is a middle-ground rock. With a silica concentration of more than 65%, granite is an acidic rock.
The most common elements in the Earth's crust, silicon and oxygen, are combined to form silica, also known as silicon dioxide (SiO 2). Silica, which makes up the majority of more than 95 percent of all known rocks, makes up 59 percent of the Earth's crust. Quartz, which is by far the most prevalent crystalline variety of silica, tridymite, and cristobalite are the other two.

Full question:
A scientist at a chemical company designs and conducts an experiment to determine if a chemical made by the company is harmful to crops. To do this, he sprays the chemical on three plants he has in the laboratory. None of the plants survive. The scientist reports that the chemical is not harmful to crops and publishes a paper stating that the chemical should be sprayed on all fields. The scientist is being
a observant
b unethical
c skeptical
d open-minded
Answer:
B. Unethical
Explanation:
In scientific experiment, Unethical action refers to actions that violate a set for moral standards/principles that is commonly held by other people in society. Usually, they do such unethical actions to obtain a personal gain by sacrificing other people.
In the example above, the scientist was fully aware that the chemical substance is dangerous (because the plants died after he sprayed the chemicals).
Despite that, that scientist chose to harmful to crops and publishes a paper stating that the chemical should be sprayed on all fields (most likely because he obtain some sort of reward from the chemical company if he show a positive research result) . This might caused a destruction to the environment and endangered the lives of a lot of people.
