B) carcinogens to stick to pulmonary cells
<u>Passive transport</u> is used by free fatty acids and monoglycerides and the glycerol is transported by <u>carrier-mediated</u> transport during the mucosal phase of digestion.
<h3>What is cellular transport?</h3>
It is the movement of molecules between the cell interior and the exterior through the cytoplasmic membrane.
<h3>Characteristics of cellular transport</h3>
- Passive transport is one where energy is not required for the substance to cross the plasma membrane, it transports part of the monoglycerides and fatty acids.
- Active transport is one where carrier proteins must move molecules against a concentration gradient, such as glycerol.
Therefore, we can conclude that active and passive cellular transport is the transfer of molecules from one side of the cell membrane to the other.

Water has a very high Specific Heat Capacity(i.e. a lot of energy needs to be absorbed by water to increase its temperature). ... Hence, the temperature of the car decreases much more than the temperature of the water increases. This is why water is a very effective cooling agent.
Answer:
The correct answer is RNA polymerase does not require a primer to add new nucleotides.
Explanation:
RNA polymerase is an important enzyme of transcription process that deals with the formation of mRNA from DNA. unlike DNA replication, transcription process does not require any RNA primer to carry out the synthesis of mRNA in 5'→3" direction.
RNA polymerase use coding strand of DNA molecule as a template to synthesize new mRNA molecule from that parental DNA molecule.
