The correct answer is a - Lipid
Lipids are not considered as macromolecules because unlike proteins, carbohydrates and nucleic acids which polymers, lipids are composed of a single unit made up a glycerol backbone to which two or three fatty acids are linked.
Lipids are not polymers made up of individual subunits called monomers. They contain only one molecule and are not macromolecuels.
Examples of lipids include waxes, steroids, phospholipids and detergents. Lipids are generally hydrophobic and insoluble in water.
<span>Since you left off the choices, I have to just present the facts of what occurs first in the nerve impusle. The first thing that will is happen is the sodium ios will move to the inside of the nueron. The second step is the potassium ions will move to the inside of the neuron. After those move into the nueron, calcium will then move into the nueron. Both the sodium and potassium have 1 postive charge. While the calcium ion has 2 positive charges. </span>

Servicing the interrupt
An interrupt is the signal to the processor from the hardware which say something about the problem that needs attention. This alerts the processor to respond and command an appropriate action to the problem. This can be done by suspending activities, saving current state and executing the interrupt handler. The interruption is just temporary after finishing the problem the processor will start again the normal activities.
