Which of the following explains the role of plants in the carbon cycle?*
Dovator [93]

Answer:

Plants transfer carbon dioxide in the atmosphere to carbohydrates in the biosphere.

Explanation:

Plants are unique organisms being that they have the unique ability to manufacture their own food via the process of PHOTOSYNTHESIS. Hence, they are called AUTOTROPHIC. Photosynthesis is the metabolic process by which plant cells make sugar (glucose) in the presence of sunlight.

However, in the photosynthetic process, plants require inorganic source of carbon called CARBON DIOXIDE (CO2) and water to perform the process. The chemical overall reaction of photosynthesis is as follows:

6CO2 + 6H2O → C6H12O6 + 6O2

This explains the role of plants in the carbon cycle as they help transfer carbon dioxide (CO2) in the atmosphere to carbohydrates in the biosphere (living organisms).

Griffith called the process he observed transformation because
Eva8 [605]

Answer:

The correct answer would be the harmless bacteria had been transformed.

Griffith used two different strains of the bacteria <em>Streptococcus pneumoniae - </em>type-III-S or smooth strain and type II-R or rough strain.

Smooth strain had protective covering around itself (protect itself from hosts's immune system) and was able to kill the mice.

Rough strain did not have any protective covering around itself  and thus could be easily removed by the immune system Hence, it was not able to kill the mice.

In addition, heat killed smooth strain was also not able to kill the mice. However, when remains of it was added with rough strain then the blend was able to kill the mice.

Lastly, he was able to isolate living bacteria of both the strains.

He concluded that non-lethal type II-R strain was transformed into lethal type II-S strain by "transforming principle" (which we know today as DNA) that was supposed to be the part of dead III-S strain bacteria.
