Which organelle is the site of the Calvin cycle? MCQ with Answer and Explanation

Explanation:
Hemoglobin has a much higher affinity for oxygen than for carbon dioxide; it binds O2 readily in the lungs. Inside RBCs, the enzyme carbonic anhydrase rapidly catalyzes the conversion of CO2 and water into carbonic acid. Approximately 70% of CO2 is transported in the blood as bicarbonate ions in the plasma. Thus, statements 2 and 3 are correct.

Explanation:
Primary productivity is the rate at which autotrophs (producers) convert solar energy into chemical energy (biomass) through photosynthesis. Secondary productivity is the rate at which heterotrophs (consumers) assimilate food to create new organic matter (biomass). Decomposition is a biological process carried out by microbes, and its rate is highly dependent on environmental factors like temperature, moisture, and oxygen availability; warmer temperatures generally increase decomposition. Thus, statements 1 and 2 are correct.

Explanation:
The nomenclature for restriction enzymes is based on the genus, species, strain, and order of discovery of the source bacterium. In EcoRI: 'E' stands for the genus Escherichia, 'co' stands for the species coli, 'R' stands for the strain RY13, and 'I' indicates that it was the first restriction enzyme isolated from this particular strain. This systematic naming convention helps scientists identify the exact source of the enzyme.
