Answer:. True
Explanation:
The risk of becoming infected from contact with an HIV-positive healthcare provider is indeed remote. The Centers for Disease Control and Prevention (CDC) have recommended the use of universal precautions by healthcare providers to minimize the risk of transmitting many infectious diseases, including hepatitis and HIV.

Answer:
gas < liquid < solid
Explanation:
As we know that density is defined as ratio of mass and volume of the object.
So here if all the molecules of the given matter is packed very close to each other then it can be said that density is high.
So here we know that solids are packed tightly to each other such that force of attraction between them is good then this is said to be high density while in gases the molecules have weak force between them so the packing of the molecules are not too good.
So here we can say that the correct order of density from least to highest is given as
gas < liquid < solid
False, the term seeing is not used to describe the measure of faint an object can be detected.
<u>Explanation:</u>
Astronomers use the term "seeing" to suggest the effect of turbulence created by atmosphere. As per telescopes, the larger the area of telescope, the more accurately it can detect fainter objects. This is because the area of telescope is directly proportional to the light collected in it.
Thus, the term seeing and ability to observe fainter object is completely independent of each other. So, it is a false statement that the term seeing is used to describe how faint an object can be detected by a telescope.
