Answer:
Scanning electron microscope.
Explanation:
It is scanning electron microscope because it is an electron microscope that produces image with three dimensional structure of the specimen by scanning the surface of the specimen using beam of electrons that is been focused causing an interaction between the electrons and atoms of the specimen which send signals that indicates information about the specimen.
Answer:
High melting and boiling points...
Explanation:
Ionic compounds typically have high melting and boiling points, and almost always electrically insulting, but when melting or dissolved they become highly conductive, because the ions are mobilize.....
Answer:
(a) negative feedback.
Explanation:
A negative feedback mechanism operates in the direction of maintaining the homeostasis. Any change from the defined range of internal conditions of the body is sensed as a stimulus. It triggers a response that restores the original range of the internal condition. This is called a negative feedback mechanism. For example, when the body temperature rises, the blood vessels present near the skin surface dilate to lose more heat to the environment. This is one of the negative feedback produced against raised body temperature.

Answer:
Both sodium and potassium ions are transported against their concentration gradients
Explanation:
In the cell, the sodium potassium pump is a type of transport, of the active type.
It requires an energy expenditure and always goes against gradient.
For every 3 Na + that leave, 2 K + enter and the action hydrolyzes an ATP (ADP + P)
