If the dna of a bird has 8% adenine, what percent of cytosine would there be ?​

42%

Explanation:

as all of the bases will be out if 100% so if adenine is 8 % thymine will also be 8% so 8+8=16

100-16=84 this is the amount of cytosine and guanine so 84÷2= 42% for cytosine.

hope this make sense

when it's short and dry.

i think it would be b. tissue because an organ system is a group of organs that work together to perform one or more functions. each does a particular job in the body, and is made up of certain tissues.
