Answer:
Between 225 and 325 grams of carbohydrates a day.
Explanation:
The Dietary Guidelines for Americans recommends that carbohydrates make up 45 to 65 percent of your total daily calories. So, if you get 2,000 calories a day, between 900 and 1,300 calories should be from carbohydrates. That translates to between 225 and 325 grams of carbohydrates a day.

A. RbOH is a base because its pH is greater than 7.
This statement is correct and points at the compound being a base because an Alkali always has a pH between 7 and 14. Starting from 7 which is a neutral compound neither acidic nor alkaline, the higher the pH value, the stronger the compound is an alkali or a base. The strongest pH compounds are those that have the pH value of 14 and the weakest alkalis are those the pH value of which is closer to 7.
None of the other options fit this criteria.
Skeletal muscles
Structure; they are long cylindrical fiber, striated, many peripherally located nuclei.
Functions; Voluntary movement, produces heat, protects organs.
Examples; the biceps, slow twitch fibers, fast glycolytic fibers.
Cardiac muscles
Structure; they are short, branched, striated, single central nucleus
Functions; Contracts to pump blood, they are found in the heart
Examples; Heart muscles
Smooth muscles
Structure; They are short, spindle shaped, no evident of striation, single nucleus in each fiber
Function; Involuntary movement, moves food, involuntary control of respiration, moves secretions, regulates the flow of blood in arteries by contraction.
Example; Muscles found in the walls of hollow organs like the intestines, stomach and the blood vessels.
they are prokaryotic and they are tolerant to extreme environments.
