Answer:
A. Yes, because the %A approximately equals the %T and the %G approximately equals the %C in both species.
Explanation:
According to Chargaff's rule, in all cellular DNAs, the number of adenosine residues (A) is equal to the number of thymidine residues (T). And the number of guanosine residues (G) is equal to the number of cytidine residues (C). Therefore, the sum of the purine residues equals the sum of the pyrimidine residues (A+ G= C+ T). It is based on the fact that a purine base always pairs with a pyrimidine base in a double helix DNA.
Chargaff’s rule is followed in all the double-helical DNA molecules irrespective of the species. In DNAs of sea urchin and salmon, the percentage of adenine is equal to that of the thymine and the percentage of guanine is equal to that of the cytosine. Therefore, Chargaff's rule is followed.
Answer:
Laboratory is the place for experiment.
Explanation:
Laboratory is the place for experiment and the purpose for that is doing research and experimentation to confirm or discover new knowledge by using scientific method. Kinetic energy is very important because it has the ability to do work. It enables the body to move from one place to another. The molecules of water in the hot water has kinetic energy which able them to escape in the air against pressure of atmosphere.
Answer:
B. The carbon cycle
Explanation:
In the carbon cycle, carbon in the atmosphere is absorbed into plants, where the plants use photosynthesis to convert that carbon into oxygen and energy for themselves. Neither of the other cycles involves a plant taking in a gas directly from the atmosphere.
Hopefully this was helpful! :)
Answer: Plants use their photosynthesis to make glucose and their chloroplast to break the glucose down to obtain ATP.
