Both DNA and RNA are types of nucleic acids. DNA stands for deoxyribonucleic acid , while RNA stands for ribonucleic acid.Both DNA and RNA carry genetic information. However, DNA is chiefly responsible for storing and transferring genetic information whereas RNA acts as a messenger between DNA and ribosomes during the process of protein synthesis and directly codes for amino acids.DNA is double stranded while RNA is single stranded.DNA has thymine in its structure but RNA does not. Instead in place of thymine it has uracil.<span>

It is a behavioral adaptation.
There are three types of adaptations:
Structural - body parts that help it survive (e.g. color, size, shape)
Physiological - systems present in an organism that allow it a special feature (e.g. venom, skin color changes)
Behavioral - an action that allows the organism to better survive
The excretory system is intended to remove any solid/fluid waste from your body, such as urine.
All you have to do is keep track of what letter matches which letter in each column. For example
(DNA strand B) A= (DNA strand A) T
You have the matching letters for each. Do you understand? If not I can help clarify. :3
