The answer to this question is DNA ONLY!
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.
The answer to this question would be false.
The solute is a substance that was dissolved by the solvent. The amount of solute that can be dissolved is called solubility. The amount of solute mostly small and if it solubility too high it will be precipitated.
There are no rules state that solute should always be the greatest amount.
<span>Membrane structure and function: The plasma membrane, also known as the cell surface membrane or plasma-lemma, is the boundary of the cell. It regulates the movement of materials into and out of the cell and facilitates electrical signaling.</span>
abiotic means things that aren't alive so rain could be one
biotic means living things - rabbits, leafy plants, foxes
There would most likely be a decrease in the population of leafy plants in the meadow.
The fox population would increase if there was a high population of rabbits since there is more food
