Question

microorganisms are involved in each of the following processes except
decomposition of organic material
o2 production
infection
smog production
food production
question 2 (bonus) (1 point)
which cellular structure is the site of protein synthesis?
golgi apparatus
lysosomes
ribosomes
nucleolus

Explanation:

1. Microorganisms play roles in decomposition of organic material (e.g., bacteria breaking down dead matter), O2 production (e.g., cyanobacteria in photosynthesis), infection (pathogenic microorganisms), and food production (e.g., yeast in baking). Smog is mainly formed by chemical reactions of pollutants like nitrogen - oxides and volatile organic compounds in the atmosphere, not directly by microorganisms.
2. Ribosomes are the sites of protein synthesis in the cell. The Golgi apparatus modifies, sorts, and packages proteins and lipids. Lysosomes contain digestive enzymes for breaking down waste. The nucleolus is involved in ribosome synthesis.

Answer:

1. D. smog production
2. C. Ribosomes
