Answer:
Sample A: 21.3%A, 28.7% G and 28.7% C
Sample B: 27.7% A, 22.3% G and 22.3% C
Explanation:
According to Chargaff's rules of base pairing, the amount of adenine in a DNA molecule equals the amount of thymine, and the amount of G=C.
<u>Sample A</u>
Contains 21.3% T, so it also contains 21.3% A. Therefore A+T= 42.6%
100% - (A+T) = (G+C)
100% - 42.6% = 57.4%
G+C add up to 57.4% of the DNA in sample A. And because G=C, there's 28.7% G and 28.7% C.
<u>Sample B</u>
Contains 27.7% T, so it also contains 27.7% A. Therefore A+T= 55.4%
100% - 55.4% = 44.6%
G+C add up to 44.6% of the DNA in sample B.
And G=C, so there's 22.3% G and 22.3% C.
<u>Answer:</u>
Most plants, most algae and cyanobacteria kinds of organisms (Autotrophs) can perform photosynthesis while heterotrophs are organisms incapable of photosynthesis.
<u>Explanation:</u>
Photosynthesis is a mechanism used among plants as well as other species to transform energy from the sun into chemical energy which may be released later to power the functions of the species.
In autotrophs (organisms who self prepare there food ) with the support of a subsequent series of light-independent reactions like Calvin cycle, creates long-term energy collection in the form of sugars, while some bacteria use different mechanisms like the reverse Krebs cycle to accomplish the same purpose.
Heterotrophs are entities unable to photosynthesize and, by eating certain species, must therefore obtain energy and carbon from the food. In the term heterotroph: hetero means "other" while troph means "feeder", thus their food depends on other species.

is a Disaccharide molecule it is to monosccarides connected by a phosphodister bond. one example would be Maltose
hope this helps!!!!
