Which of the following best explains how hydrogen bonding aftects the heat of vaporization for water?

Biology

dlinn [17]3 years ago
5 0

Answer: A. The hydrogen bonds cause water to resist a change in temperature.

Explanation:

Heat of vaporization is defined as the amount of heat required to convert 1 mole of liquid to gaseous state.

Water has high heat of vaporization due to the presence of strong hydrogen bonds between  hydrogen and a electronegative element oxygen. As the water molecules are strongly bonded to each other, large amount of heat is required to raise the temperature of water.

The molecules will not be able to gain enough kinetic energy and thus temperature changes slowly.

The diagram shows the thermohaline circulation, also know as the ocean's conveyor belt.
DanielleElmas [232]

Answer:

The statement that is true about red currents in the thermohaline circulation is that  water in the red currents contain less salt (option A).

Explanation:

Thermohaline circulation is a concept used in oceanography, referring to the oceanic circulation that depends on factors such as surface heat and salinity, as well as the density gradient that they determine.

On a map, the different currents that are part of the thermohaline circulation are usually represented with blue and red lines, where:

  • <em>The blue lines represent deep, cold, dense and higher salinity currents.</em>
  • <em>The red lines represent surface currents, warm, with less salt content, so they are less dense.</em>

The red currents (see image) represented on the map have less salt content, compared to the currents represented in blue.

Scilla [17]

It is most likely due to the fact that the attenuation is the evolutionary relic, which by accident has remained does not support the actual reason of the dual control to regulate the operon.

Answer: Option E

<u>Explanation:</u>

In bacteria transcription and translation carries out at the same time so or the termination of transcription in premature phase in bacteria uses a special mechanism which is called as attenuation T.

he attenuation in bacteria is a regulatory mechanism. Trp operon is the group of codes of the components. These operons are the actual functioning group of the DNA.
