Which of these would best describe the outcome of increasing the kinetic energy of the molecules in the above picture
masya89 [10]

The question is incomplete, the complete question is:

Which of these would best describe the outcome of increasing the kinetic energy of the molecules in the above picture? A) The temperature will increase. B) The temperature will decrease. C) The temperature will remain unchanged. D) The temperature would fluctuate up and down.

Answer:

The temperature will increase

Explanation:

Temperature is defined as the average kinetic energy of the molecules of a body. Increasing the kinetic energy of the molecules will also increase the temperature of the molecules.

Similarly, kinetic energy is proportional to temperature. Hence an increase in the kinetic energy of molecules also leads to increase in the temperature of the system.

Function of cell structure Description
Anton [14]

Answer:

<em>The correct option is C.</em>

Explanation:

The structure mentioned in the question is cell membrane. The cell membrane can be described as a semi-permeable membrane which regulates the export and import of particles across the cell membrane. Some molecules move inside the cell along the concentration gradient by passive transport while other molecules move inside through active transport i.e against the concentration gradient.

The cell membrane is made up of phosphate head and fatty acid tails.

Mrrafil [7]

Answer:

The two enantiomers of dopa have very different shapes, even if they have the same number of atoms of each element involved and have the same ones connected to one another. The great difference in activity shows that the key thing in determining biological activity is shape, not merely the number or arrangement of atoms.

Explanation:

  • The two enantiomers of dopa have very different shapes, even if they have the same number of atoms of each element involved and have the same ones connected to one another.
  • The great difference in activity shows that the key thing in determining biological activity is shape, not merely the number or arrangement of atoms.

The diffusion of water through a selectively permeable membrane is called osmosis.
Sergeeva-Olga [200]

B

The answer is B because,If the the water concentration of sugar particles is greater than that of the medium(the medium is a hypertonic solution) the number of sugar molecules diffusing out will be more than than that entering and the cell will shrink and shrived due to osmosis
