Consider the cooling curve above. The substance is changing state from a gas to a liquid to a solid. As the temperature changes

Anni [7]

Answer: B) there is a decrease in kinetic energy and the molecules get closer together.

Explanation: Kinetic energy is directly proportional to temperature, thus as temperature decreases, kinetic energy also decreases.

Gas is the state of matter in which particles are very loosely bound and hence can easily move past one another very easily and have highest kinetic energy.

Liquid is the state of matter in which particles are loosely bound and hence can move past one another easily and have high kinetic energy.

Solid is the state of matter in which particles are tightly bound and hence can not move easily and have low kinetic energy.

Thus on moving from gaseous to solid state, the kinetic energy decreases and the molecules get closer together.

Which of the following statements accurately describes specific bacterial cell walls? View Available Hint(s) Which of the follow

svetoff [14.1K]

Answer:

In gram-negative bacteria, the thin layer of peptidoglycan is surrounded by an outer membrane made of phospholipids, lipopolysaccharides, and proteins. This statement accurately describes specific bacterial cell walls.

Explanation:

The Gram- negative bacteria constitute of an outer membrane which is richly made up of lipopolysaccharides, phopholipids and proteins. The lipopolysaccharides function mainly as a virulence factor and are involved in causing variety of diseases in animals.

Gram- negative bacteria can be seperated from gram- positive bacteria mainly because of the thickness of peptidoglycan and by the presence of the outer membrane of Gram- negative bacteria. The outer membrane is absent in Gram- positive bacteria.
