THE ANSWER IS C ( genetic mutation) ON USATestPrep because...

Explanation:

Many bacteria have acquired the ability to produce an enzyme called penicillinase, which destroys penicillin. All enzymes are proteins. The ability to produce the new protein penicillinase came from a change in the bacterial DNA: a genetic mutation.

Water, H2O, and methane, CH4, are both covalent substances. Why is water a liquid at room temperature while methane is a gas? A
tino4ka555 [31]

The right answer is D.

Intermolecular forces lead to the assembly of microscopic systems. They are responsible for the cohesion of matter in most macroscopic phases. These are weak forces compared to covalent bond strengths. They do not modify the nature of the molecular species and only influence their mode of assembly. The most well-known intermolecular bonds are the Van der Waals bond and the hydrogen bond.

The greater the intermolecular forces, the more the aspect of the element will tend to be more condensed (gas <liquid <solid).

What layer of the atmosphere contains almost 80% of the atmospheres total mass
irina [24]

Solution:

The troposphere is the atmospheric layer closest to the planet and contains the largest percentage (around 80%) of the mass of the total atmosphere.

The troposphere is the lowest major atmospheric layer, extending from the Earth's surface up to the bottom of the stratosphere. The troposphere is where all of Earth's weather occurs. It contains approximately 80% of the total mass of the atmosphere.  

The troposphere is characterized by decreasing temperature with height (at an average rate of 3.5 degrees F per thousand feet, or 6.5 degrees C per kilometer). In contrast, the stratosphere has either constant or slowly increasing temperature with height.  

Thus the right answer is troposphere.
