Detrimen WHY the following statement can occur in DNA ? a. the sequence -A-C-C-T-C-G- may be present in the DNA molecule

c. the ratio A: T and C: G is the same in the DNA molecule

e. the sequence -C-G-U-A-A-G-may be present in the mRNA molecule

f. the sequence -T-G-C-A-C-U- can not occur in the RNA molecule

How can I answer this question ?
Thanks aot​

Which plant has a visible leaf modification that will it conserve water in extremely dry environments?

During the day, plants produce by splitting water molecules in the light-dependent reactions of photosynthesis. at the same time, plants use cellular respiration to produce some of the needed by the light-independent reactions to make sugars. during the night, plants produce because takes place.

Define the apical impulse and describe its normal location, size, and duration. which abnormal conditions may affect the location of the apical impulse? explain the mechanism producing normal first and second heart sounds. describe the effect of respiration on the heart sounds. describe the characteristics of the first heart sound and its intensity at the apex of the heart and at the base. describe the characteristics of the second heart sound and its intensity at the apex of the heart and at the base.
