GEOLOGY

Detailed explanation-1: -A biologist is a scientist who studies living organisms. Studying life can mean many different things and be very complex.

Detailed explanation-2: -A biologist is a scientist who focuses on living organisms, including plants and animals. Wildlife biologists might specialize in studying African elephants.

Detailed explanation-3: -Biologists study humans, plants, animals, and the environments in which they live. They may conduct their studies–human medical research, plant research, animal research, environmental system research–at the cellular level or the ecosystem level or anywhere in between.

Detailed explanation-4: -For this reason, living things are called organisms. The activities of the cells are controlled by the cell’s genetic material-its DNA. In some types of organisms, called eukaryotes, the DNA is contained within a membrane-bound structure called the nucleus.

Detailed explanation-5: -Biology and life science are two distinct academic fields. Biology is the scientific study of life and living organisms, whereas life science is a broader term that encompasses any scientific study of life.
