Scientists rely on concepts when researching crop production and medicine.

Scientists rely on biology concepts when researching crop production and medicine.

Explanation:

To understand this answer we need to evaluate all the options.

a) biology is related to the growth, development, and life of organisms. Crops are organisms, in other words living beings. Therefore biology is the case to go, however for medicine is a different case. Because the majority of medicines come from nature, that is why it is also biological sources. Some medicines ar synthetic however they are also based on organic and natural elements.

b) physics. This discipline can be really good to find data on certain topics, like the effects of ions, molecules, and gravitational events related to living beings. However, scientists haven't found physics fact that can explain crops and medicines better than medicine. Therefore is wrong.

c) geology. Geology can be meaningful for crops and medicine. Because we can understand many crops and medicine based on the context of the environment. However, it doesn't explain life, growth, or any other life topic. So, it is incorrect.

d) astronomy could explain many topics, in the same way, Geology about the context of the development of the crop or the plant that produces the element that is used to create medicine. However, it doesn't explain the impact of their existence, their effect on organisms, or their production.

answer; the above statement is (true);
