The differences in heat give rise to three different zones, Torrid, Temperature, and Frigid Zone.
<h3>
<u>
Explanation:</u></h3>
There are major five types of vegetative patterns in the world these are forest, grassland, Tundra desert and Ice sheet. In these regions, different types of vegetation are grown.
The growth of vegetation depends on the amount of heat received. The difference in heat gives rise to major 3 zones. These zones are:
1. Torrid zone- this zone lies between 0 degrees to 23 half a degree north and south to the equator. The sun shines exactly overhead at the places near the equator and in the tropics. Therefore the equatorial and tropical regions receive maximum insolation.
2. Temperate zone- this zone lies between 23 half a degree to 66 half degrees north and south of the equator. This zone experiences the slanting rays of the sun. Due to the spherical shape of the earth, the amount of insolation received by this region is less.
3. Frigid zone- this zone is located between 66 half degree and 90 degrees north and south to the equator. This zone experiences extremely slanting rays of the sun over a large distance. Hence the amount of insolation received is very less.

Answer:
The excess of CO2 emitted from anthropogenic sources is being absorbed by the oceans from the atmosphere. This results in more hydrogen ions in the ocean, which increases acidification.
A helicase enzyme unwinds the DNA molecule, then corresponding nucleotides are added to the separated original strands forming two semi-conservative molecules - best describes that genetic information is conserved during replication process.
Explanation:
The process of DNA replication is semi-conservative, where each of the strand of the double helix DNA replicates itself to form two daughter helices, each with one parental helical strand or content.
The parent strands acts as the template for daughter helices formation and their genetic information are conserved and stored in the daughter helices.
DNA helicase is an essential enzyme which takes part in DNA replication. Its major role is to begin the conservation replication by unwinding each of the strands of the coiled DNA double helix strand. This unwinding will open the double helix into a Y-shape.
Later other enzymes RNA primase, DNA polymerase, and DNA ligase further works in the replication process which proceeds with addition of corresponding nucleotides to the strands and linking of the leading and lagging strands.
