how are two identical DNA molecules formed

Answers

Answer 1

Answer:

Explanation:

DNA is a double stranded molecule. When DNA is copied the two strand of DNA (old strands) separate and new nucleotides match up with the two separated strands. This process creates two identical double stranded DNA molecules are formed. Each DNA molecule contains one strand of the original DNA molecule and one newly synthesized (made) strand.

hope it helps :)

Answer 2

Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin. Several enzymes and proteins then work together to prepare, or prime, the strands for duplication. Finally, a special enzyme called DNA polymerase organizes the assembly of the new DNA strands. The following description of this three-stage process applies generally to all cells, but specific variations within the process may occur depending on organism and cell type.

Answers

Answer:

Substitution of other materials for wood products

Recycling of paper products.

Expansion of farming

Explanation:

To decrease the rate of deforestation, we have to make a substitute of other materials for the wood products in order to lower the demands of wood. Recycling of paper and other wood products which can be used again that reduces the demands of wood and lowers the cutting of trees. If we expand the farming of trees for the wood purpose, so we can fulfill our needs of wood and there is no need for the cutting of trees for fulfilling the demand of the wood.

Based on this data, what can be concluded about the impact
seasonal changes have on these organisms around the Barents Sea?

A. The availability of solar energy limits photosynthetic productivity in winter months

B. Seasonal Changes have no impact on these organisms

C. During winter months the Diatom and zooplankton population completely die off due
to the lack of sunlight.

D. Due to the availability of solar energy, Diatom mass peaks in July.

Answers

Answer:

D. Due to the availability of solar energy, Diatom mass peaks in July.

Explanation:

Diatom are the photosynthetic algae which prepare food for themselves from the solar radiation just like plants. These diatoms produce more biomass or vegetation in the summer season mainly in July because availability of more sunlight in the Barents sea region while on the other hand, less biomass in the winter season due to low temperature and solar radiation which also effects the population of zooplankton organisms. So we can conclude that seasonal changes have a great impact on the organisms living around the Barents Sea.
