Which statement below best summarizes the
monitta

Answer:

D. Clear-cutting would increase the amount of carbon dioxide found in the atmosphere

Explanation:

Plants including trees are organisms that help maintain the balance of carbon in the carbon cycle. They do this via the process of PHOTOSYNTHESIS, which is the way they obtain their energy and carbon source. During photosynthesis, trees (plants) absorb carbon in form of atmospheric carbon dioxide (CO2) from the air through the STOMATA on their leaves.

CO2 is an input substance in order for photosynthesis to occur. In a case where all the trees (plants) of a forest has been clear cut or removed, there will be no organisms to directly absorb the carbon dioxide (CO2) released into the atmosphere via respiration. Hence, the amount of carbon dioxide found in the atmosphere would increase.

DNAase is an enzyme that catalyzes the hydrolysis of the covalent bonds that join nucleotides together. What would first happen
Free_Kalibri [48]

DNAase is an enzyme that catalyzes the hydrolysis of the covalent bonds that join nucleotides together. What would first happen to DNA molecules treated with DNAase?

A) The purines would be separated from the deoxyribose sugars.

B) The pyrimidines would be separated from the deoxyribose sugars.

C) All bases would be separated from the deoxyribose sugars.

D) The two strands of the double helix would separate.

E) The phosphodiester bonds between deoxyribose sugars would be broken.

Answer:

E) The phosphodiester bonds between deoxyribose sugars would be broken.

Explanation:

The purines and pyrimidines of two DNA strands of a DNA duplex are held together by hydrogen bonds. Hydrogen bonds are not covalent bonds. The enzyme DNAase targets the phosphodiester bonds. These are the covalent bonds that join two deoxyribonucleotides of a DNA strand together. therefore, when a DNA is subjected to digestion with DNAase enzyme, the phosphodiester bonds will be broken that hold the pentose sugars of two nucleotides by a phosphate group.

Mr. Jones, the science teacher, tells his students that energy cannot be created; it must be captured from the environment. He i
natta225 [31]
<span>A: food chain

</span><span>In many functions of a living organism, it cannot make its own energy. It uses energy from its environment, retrieves and converts into a usable and edible matter. Organisms that can do this process is the autotrophs, they can facilitate photosynthesis which they gather energy from the sun, water and carbon dioxide in order to create energy by then, the transfer of this energy to other organism is played by the food chain –food web. </span>
