<h2>Cyanobacteria </h2>
Explanation:
Simple cyanobacteria (single-celled organisms that can produce oxygen through photosynthesis) played a key role in providing Earth’s atmosphere and oceans with oxygen
Cyanobacteria or the blue green algae are the only bacteria that contain chlorophyll A, a chemical required for oxygenic photosynthesis, the process which uses carbon dioxide, water and sunlight to produce oxygen and glucose (sugars) for energy
In this process chlorophyll A helps in capturing the energy from sunlight
In addition to chlorophyll A, blue-green algae also contain the pigments phycoerythrin and phycocyanin, which give the bacteria their bluish tint
All the above characteristics of cyanobacteria can be used as a source of renewable energy by converting sunlight into electricity
Answer:
A- phosphate group
B- 5-carbon sugar
C- nitrogenous base (adenine is a purine, just in case)
D- nitrogenous base (uracil is only found in RNA)
E- 5-Carbon sugar
F- phosphate group
Explanation:
<span>The exfoliative toxin is responsible for a skin disease called staphylococcal scalded skin syndrome. This exotoxin, exfoliatin is produced by Staphylococcus aureus and it induces the formation of fluid-filled blisters with easily ruptured, thin walls, usually in infants. Exfoliatin has the protease activity which causes peeling of the skin by destroying adhesion between keratinocytes (skin cells).</span>
