Answer & explanation:
The cell was discovered in 1669 by the English scientist Robert Hooke when looking at a piece of tissue in a two-lens microscope. Hooke was able to visualize small cavities in the experiment piece, then naming such cell cavities.
Only a century and a half after the discovery of the cell, that the Cell Theory was launched, replacing the theory of spontaneous generation (or abiogenesis).
Before that, many scientists were already busy understanding the structure and functioning of the cell, generating knowledge that became fundamental to the development of biology, specifically cytology, a branch of science that studies the structure, functions and development of cells.
Anatomy
Anatomy is the branch of biology that deals with the study of the structure of organisms and their parts.
Biochemistry
Biochemistry is the branch of biology concerned with the chemical and physiochemical processes that occur within living organisms.
Biophysics
Biophysics is the science of the application of the laws of physics to biological phenomena.
Biotechnology
Biotechnology is the exploitation of biological processes such as genetic manipulation of micro-organisms for the production of antibiotics, hormones, etc.
Botany
Botany is the scientific study of plants, including their physiology, structure, genetics, and ecology.
Cell Biology
Cell biology is the study of cell structure and function, and it revolves around the concept that the cell is the fundamental unit of life.
Evolution
Evolution is the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth (Darwinism)
Genetics
Genetics is the study of genes, genetic variation, and heredity in living organisms.
Immunology
Immunology is the branch of medicine and biology concerned with immunity.

The right option is; d. Immune system
The immune system is responsible for defending the body against harmful substances.
The immune system is the body’s defense system that protects the body against infectious pathogens and other invaders. The immune system is composed of many biological structures (special cells, proteins, tissues, and organs) and processes that functions together to protect the body. White blood cells are one of the important cells of the immune system that destroy harmful substances or disease-causing organisms that invade body systems.

It is <u>true </u>that i<span>n operant conditioning, many complex behaviors are learned through shaping.
This means that you learn many new things through consequences that you experience. So, for example, when you're a kid, you are constantly being told not to touch a hot stove. But given that you are small and inquisitive, you still touch it and burn your hand. After that, you learn that touching something hot is going to hurt you, so you learn not to do it through a consequence.</span>
