Answer:
Explanation:
A root has an outside layer, the epidermis, and a central cylinder of a vascular tissue. Between these two tissues lies a large area of ground tissue.
All vertebrates are, by nature, in two classes : the male class and the female class. Only some invertebrates like the earthworm, water snail etc are in single class with both male and female organs in the same body.
That’s the general structure of an amino acid.
Answer:
The correct answer is - D
. Na transport out of the cell requires ATP hydrolysis
Explanation:
Sodium-ion moves or transported from the inside of the cell to the outside the cell by the process called active transport. Active transport takes place takes place when the movement is against the concentration gradient to a higher concentration area through the cell membrane.
Active transport requires energy in order to transport the molecules or ions from low concentration to high concentration. In sodium-potassium pump get the energy from the hydrolysis of the ATP.
