Mitosis = Division of the cell’s genetic material
Cell cycle = All the life processes of the cell, including cell division
Cancer = Disorder in which the cell cycle is disrupted, causing uncontrolled cell growth
Binary fission = Process that prokaryotic cells use to divide
Synthesis = Phase when DNA replication occurs
Checkpoint = Point in the cell cycle where the cell verifies that it is ready to go to the next phase
Answer:
The correct answer is- Immune system
Explanation:
There are physical, chemical and immunological barriers present in our body which helps us to protect from the foreign antigen. They all assist each other and helps in pathogen removal from our body.
The physical barrier includes skin, gastrointestinal tract, respiratory tract, etc which do not allow the microbe to enter the body. Chemical barriers include tear, saliva, acid in the stomach which kills microbes on the body surface.
Immune cells like macrophages, B cells kills microbes when it gets in the body. Lymphatic system also contain immune cells and helps in microbe removal.
So the immune system is assisted by physical barrier, chemical barrier, and lymphatic system.
Enzymes are substances necessary for the synthesis of most materials in an organism
