Accoring to the Chargaff's first rule of base pairing, each of the four nucleotide bases has its own complimentary match, that it always bids with.
So, Adenine always bonds with Thymine and Cytosine always binds with Guanine.
If you know the concentration of one base, in our case Cytosine, then you can easily calculate the percentage of other bases.
Since Cytosine and Thymine are always paired, there is an equal amount of both of them -16%.
So, 16% C + 16G = 32% of the whole DNA.
This means that the other two base pairs A and T make up to 68% of the DNA.
Half of the 68% is Adenine = 34% and half of it is Thymine- 34%.
So, the percentages of base pairs in the DNA sequence are :
16% C
16% G
34 % A
34 % T
They get their energy from the sun so your answer will be D.

The incorrect statement is: C) It transports mainly sugars and amino acids.
Xylem together with floem is a plant tissue involved in the transport of substances through the plant.
Xylem’s role is to transport water (sometimes and nutrients) from roots to stems and leaves and to provide support to the plant. Xylem consists of a specialized, water-conducting cells - tracheary elements (tracheids and vessel) which are long, narrow and hollow.
Answer:B
Explanation:
Selective breeding is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits by choosing which typically animal or plant males
