Answer:

Thymine

Explanation:

Adenine is a Purines together with Guanine .

Purines always pair with Pyrimidines ; which are cyosine and Thymine.

This is a complementary base pairing that hold the two strands of DNA bases together by weak hydrogen bonds for flexibility and easily unwind during replication

Purines are larger in size beaxuae they have 2 ring structures while Pyrimidines aee smaller because of one ring structure.

Therefore two purines (Adenine and Guanine can not pair together;

It must be a Purines -Pyrimidines pairs.

Therefore Adenine must pair with Thymine and cyosine with Guanine

In RNA, Thymine are replaced with URACIL as Pyrimidines.

Describe how lymph nodes and organs help the immune system fight pathogens.
I am Lyosha [343]

The defense system of the human body is made up of entire organs and vessel systems like the lymph vessels, but also of individual cells and proteins. The inner and outer surfaces of the body are the first barriers against pathogens (germs). These surfaces include the skin and all mucous membranes, which form a kind of mechanical protective wall.

Several things support this protective wall:

<span><span>- The body’s own antibacterial substances can disable different pathogens from the environment at an early stage. A certain enzyme found in saliva, the airways and tear fluid destroys the cell walls of bacteria.
</span><span>
- Many pathogens that are breathed in get stuck to mucus in the bronchi and are then moved out of the airways by hair-like structures called cilia.
</span><span>
- Most pathogens that enter the body together with food are usually stopped by stomach acid.
</span><span>
- Normal flora, harmless bacteria that reside on the skin and many mucous membranes in the body, also help to protect the body.</span></span>

The cough and sneeze reflex can also help to remove pathogens.


Hope this helps (:
