Now that you have come up with an equation that describes the relationship between amounts of different nucleotide bases in DNA,
Colt1911 [192]

Answer:

G=21 %

T= 29 %

A= 29 %

Explanation:

Since C only binds to G, you have the same amount of C and G, so G is 21 %.

100 % minus 42 % ( 21 % C plus 21 % G=) equals 58 %.

So the other 58 % is made of T and A. Since T only binds to A , the half of the extra 58 % is T and the other half is A. Therefore 29 % is T and 29 % is A

The disease diabetes mellitus is due to either destruction of the cells that produce insulin or a decrease in sensitivity of tar
jenyasd209 [6]

Explanation:

Diabetes mellitus results from a deficiency in the amount of insulin released from the pancreas in response to glucose (type I) or from a decrease in the ability of muscle and fat cells to respond to insulin (type II). In both types, the regulation of blood glucose is impaired, leading to persistent hyperglycemia and numerous other possible complications in untreated patients such as tissue damage, raises the risk of heart-attack, kidney disease and vision deterioration. Type I diabetes is caused by an autoimmune process that destroys the insulin-producing B cells in the pancreas. Also called insulin-dependent diabetes, this form of the disease is generally responsive to insulin therapy. Most Americans with diabetes mellitus have type II, but the underlying cause of this form of the disease is not well understood.

In photosynthesis what form of energy is sunlight converted two major reactions that take place
Arte-miy333 [17]
<span>Sunlight emits light energy which is absorbed by the thylacoids in the chloroplasts of a plant. Chloroplasts are organelles in a plant cell whose funtion is photosynthesis (the use of light to make energy). Thylacoids are a part of the chloroplast which absorbs light. The thylaciods convert the light into energy molecules NADPH and ATD. The Calvin cycle then takes place in the stroma (gellatinous matrix of the chloroplast). The Calvin cycle is the use of ATP and NADPH plus carbondioxide to produce starch. Starch is the polysaccharide sugar formed from glucose synthesized in a linear chain. The starch is the storage of the glucose which is used as an energy source for the plant cells. </span>
