Answer:
This is the basis for Chargaff's rule; because of their complementarity, there is as much adenine as thymine in a DNA molecule and as much guanine as cytosine. Adenine and thymine are connected by two hydrogen bonds, and cytosine and guanine are connected by three hydrogen bonds
Answer:
Chloroplasts are organelles that are filled with a green substance known as Chlorophyll. Chloroplasts are what convert water and sunlight into sugar/food, in a process known as photosynthesis. Plants can't hunt or gather food, so they make their own through chloroplast's. The Mitochondria are the powerhouses of cells.

The answer is earthworms.
Earthworms live in the soil where they feed on plant material. By eating and digesting plant material, they mix it with soil mineral components. Now, the organic matter is improved. It is then excreted into the soil becoming high-quality humus. This humus contains many mineral elements, such as nitrogen, phosphorus, calcium, magnesium, etc. Therefore, earthworms <span>help fertilize the soil by shedding digestive material.</span>
The difference between the speed of 100m race and 5000m race is larger because the difference between speed is more.
Explanation:
In the question given above we can see that in the first case the difference between both the distances that is 100m and 5000m is 4900m that is, (5000-100) . On the other hand the difference between the distance in the second case is (10000-5000) that is 5000m.
By comparing both the cases we can see that there is a difference of 100. Thus, we can say as the runner covers a distance of 100m it takes 10.44 m/sec and 5000m at 6.60m/sec , the speed difference is more.
