If a Tigers DNA has 20% Adenine then what percent Guanine does it have? (answer with the number only, no percent sign)

The answer to your question is 30

Explanation:

DNA is composed of 4 nitrogenous bases: Adenine, Cytosine, Guanine and, Thymine.

These base form pairs, Adenine attach to Thymine and Cytosine attach to Guanine.

If a tiger has 20% Adenine that means it also has 20% of Thymine. Total 40% and the other 60 % are Guanine and Cytosine.

Which means  30% Guanine and 30% Cytosine

parasites can detrimentally affect their host, but also must not allow their host to die before they can complete their life cycle. some parasites have complex life cycles with many different hosts, and have had to find ways of persisting in many different environments during the change from one host to another. ectoparasites live outside the body of the host, and can more easily  disperse, but are  more exposed to predators, parasites, parasitoids. endoparasites live inside the body of the host, and are therefore protected from the outside environment. but they can be  attacked by the host's immune system. they have therefore developed  mechanisms for dispersal such as  complex life cycles.
