In your body<span>, the excretory system helps to keep salts and urea from building up to dangerous levels and becoming toxic.

Salutations!
Organisms that derive their energy from the sun and carbon from carbon dioxide area photoautotrophs. These organisms carry out photosynthesis. Examples of photoautotrophic organisms are: algae, green plants etc.
Hope I helped (:
Have a great day!
Your hypothesis is incorrect considering every day has the same length to it.
Answer: 22% Cytosine
If Thymine is at 28% and Thymine always pairs with Adenine (another compound that is one of four constituents of nucleic acids, often paired with Thymine in double-stranded DNA), then Adenine is also 28%. The remaining 44% will then be divided between Cytosine and Guanine (another compound) since they also form pairs.
Natural selection is what the process is called.I hope this helps.
