Answer:
The correct answer is "option a. it is likely it will pass to the offspring; option b. it is not very likely that it will pass to the offspring".
Explanation:
In order that a mutation could be passed to the offspring it is necessary that the affected DNA can be transmitted to the following generation. A single bacteria that contains a positive mutation in its DNA is likely to pass its mutation to the offspring since it multiples by binary fission. On the other hand, a skin cell most likely will not pass its mutation to the offspring since a skin cell is not involved in the organism reproduction, such as a sexual cell.
All carbohydrates are made up of carbon, oxygen, and hydrogen.
The chemical formula for Glucose is
.
The chemical formula for Fructose is the same as that of Glucose. The difference between the two is how they are structured.
The chemical formula for Sucrose is
.
As you can see in the chemical formulas of Glucose, Fructose, and Sucrose, they are all made up of the elements carbon, hydrogen, and oxygen.
