Answer: Based on the previous courses a nucleic acid polymer grows in the form of DNA or RNA.
Explanation:
The polymer of nucleic acid is DNA or RNA which is known as the genetic material of the organism.
The main function of DNA is the transferring the genetic information from one generation to another generation.
RNA is the genetic material found in some of the viruses.Example is TMV( tobacco mosaic virus)
These two polymers are made of nucleic acid, sugar and phosphate.
Answer:
The correct answer is minority influence.
Explanation:
According to the concept of minority influence, the smaller groups will affect the individuals on the basis of their opinions and perspectives on the topics, which are not witnessed by many. They develop a perception, which is not common and majorly are from their observations of the things, which are required to get better in the humanity and community.
Ice forms from the top of the water column down, creating a protective barrier over the liquid water.
The higher-density liquid water shelters organisms from cold air better than the less-dense ice.
The higher-density liquid water traps nutrients for primary producers better than the less-dense ice.
Answer:
The higher-density liquid water shelters organisms from cold air better than the less-dense ice.
Explanation:
Because of this difference in density, the waters of lakes and seas do not freeze completely because a less dense ice layer forms on the surface and creates a natural thermal insulator that makes the water below it remain in the liquid phase. This saves the animal and plant life of lakes and seas.
Ice works as a thermal insulator because its specific heat (2.03 J/g. ºC) is lower than that of water (4.18 J/g. ºC).
After the cold is over and the hot season comes, the surface ice melts easily. But that would not happen if the ice dropped to the bottom of lakes and seas. With this, the animal and plant life would be compromised.
Another important point is that, as already mentioned, liquid water reaches its maximum density at approximately 4ºC, which is 1,000 g/cm3. Therefore, during times such as spring and fall, the water reaches temperatures near this and becomes denser than the rest, going to the bottom. This causes a vertical movement called the convection current, which is responsible for mixing the nutrients dissolved in water.
The higher-density liquid water shelters organisms from cold air better than the less-dense ice.
