<span>It was the culmination of research in the 1930s and early 1940s at the Rockefeller Institute for Medical Research to purify and characterize the "transforming principle" responsible for the transformation phenomenon first described in Griffith's experiment of 1928: killed Streptococcus pneumoniae of the virulent strain type III-S, when injected along with living but non-virulent type II-R pneumococci, resulted in a deadly infection of type III-S pneumococci.</span>

Photosynthesis occurs in photosynthetic ____ localized in large organelles known as ____. a. membranes; chloroplasts b. proteins
Aleks [24]

Answer:

The correct answer is option a. Membranes; chloroplast.

Explanation:

Photosynthesis is the process is specific to green plants and other photosynthetic organism converting light energy into storage energy by forming glucose from carbon dioxide and water and oxygen released as a byproduct.

This process involves the green pigment present in the plants called chlorophyll located in the chloroplast. The chloroplast is a double membrane organelle present in green plants. The membranes of the chloroplast are the site of photosynthesis.

Thus, the correct answer is option a. Membranes and chloroplast

How are land, air, water and living things impacted by too much carbon dioxide?
choli [55]

Answer:

- In terrestrial environments: increasing CO2 levels cause an increased photosynthetic rate

- In aquatic environments: increasing CO2 levels cause an increase in water acidity  

- In both terrestrial and aquatic environments: increasing CO2 levels lead to an overall increase in the average temperature (global warming)

Explanation:

In terrestrial ecosystems, rising carbon dioxide (CO2) levels increase the rate of photosynthesis (since CO2 is one of the reactants in photosynthesis), thereby also increasing plant growth. Moreover, in aquatic ecosystems, rising CO2 concentrations increase the levels of this gas dissolved on the surface of the oceans. This increases the acidity of the oceans, thereby modifying habitats and food web structures. The increasing acidity of the oceans also reduces the amounts of carbonate, which difficult for aquatic species (e.g., corals) to form their shells/skeletons. Finally, CO2 is a greenhouse gas that contributes to the increase in the average temperature by absorbing solar radiation that would otherwise have been reflected by the Earth's surface, and this increase in the temperature negatively affects life in both terrestrial and aquatic environments.
