Answer:
The correct answer is they both contain carbon but only nucleic acid contain phosphorous.
Explanation:
Carbohydrates are Polyhydroxy aldehydes or Polyhydroxyketones.Carbohydrates are composed of carbon,hydrogen and oxygen.The general formula of carbohydrate is CnH2nOn.
Nucleic acid on the other hand composed of nucleotides that contain nitrogen base ,ribose sugar and phosphate group.
The phosphate group is absent in carbohydrates.
Answer:
a. The corn borer must have or generate (by mutation) heritable variation in resistance to the toxic protein.
b. The resistant corn borers must survive better or reproduce more than nonresistant corn borers.
Explanation:
When there is a change in the surroundings of organisms, some genetic variations become beneficial to the organisms. Natural selection favors the organisms having these genetic variations.
The development of resistance in the corn borer population requires the presence of the gene for the resistance in the population. If there is no gene already present in the population, there should be a mutation to give rise to such gene/s. The corn borers having this gene should be able to survive better in the presence of the toxic protein and should leave more progeny in order to increase the frequency of the gene in the population over the generations.
Answer:
Object A but not object B
