Cells

Cells are base building blocks of life. Every living thing is made up of cells- plants, animals, and humans.

mezya [45]

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.

It is a fine balance. if you went up to two eagles on same land they would run out of food quickly and then would either starve or have to move on and using up all the food doesnt help them so it needs to be in a fine balance.

Lera25 [3.4K]

Answer: Exhaled air containing Carbon dioxide bubbles react with water to form carbonic acid . The solution turn acidic and turn from green to yellow.

Explanation:

Exhaled carbondioxide bubbles reacts with water to form carbonic acid, the solution will turn acidic. Carbonic acid is a weak acid that decrease pH. An indicator of it shows that the solution turns from green to yellow.

Co2+ H2O= H2Co3.

The solution then dissociate to give H ion and hydrogen carbonates ion.
