Answer:

Glucose

Explanation:

Because of the following factors, glucose serves as the brain's primary energy source. Glucose may be easily catabolized to provide energy to the brain since it cannot tolerate interruptions in energy flow. Since the brain cannot store calories, a quick supply of chemicals that can provide energy is essential for the brain's smooth operation. In this situation, blood can easily transfer glucose. Although fatty acids provide a source of energy for the rest of the body, they are unable to cross the blood-brain barrier because they are bound to blood albumin in blood plasma. These justifications explain why glucose serves as the brain's main source of energy. Ketone bodies could be the secondary source.

For larger distances such as the distance between objects in the far reaches of our galaxy astronomers ensure in units of?

Scorpion4ik [409]

Answer:

Lightyears

Explanation:

When dealing with very large interstellar distances, astronomers do not use the regular miles, kilometers, or meters we are used to. This is because they are just too small to be used as a metric when measuring such large distances. As a matter of fact, the earthly number system will quickly be exhausted when trying to measure some of these interstellar distances.

Instead, astronomers make use of Lightyears. Lightyears are defined by the distance traveled by an object moving at the speed of light if it was moving constantly at that speed for one year.

This can properly be used to estimate interstellar distances. since its value is very large. 1 lightyear = 9,461,000,000,000 Km

If we say that our closest star is 9 lightyears away, we are saying that it will take an object moving at the speed of light 9 years to travel from that star to our planet.

While swabbing objects to sample bacteria, you want to create a negative control to ensure that you are practicing proper asepti

irina1246 [14]

The result which would be seen from a properly prepared negative control is nothing.

<h3>What is a Negative control?</h3>

This type of control is used to test and ensure that in the absence of the antigen we do not still get a positive reaction.

Since proper aseptic technique was practised and there was no swabbing of the surface then there would be nothing seen in the properly prepared negative control.
