What does a culture medium provide to a living cell? a. visible light b. a petri dish c. water d. oxygen-rich air

Option C. Water

Explanation:

The growth medium is used to promote the growth of microorganisms. The medium can be liquid, solid or semi-solid. There are various types of growth media like culture media, transport media, selective media, differential media and minimal media. The culture media do not contain selective element in the media for growth of cell.

The undefined media contains salts, water, nutrients and carbon source. The defined media contains known elements and no plant, yeast or animal tissue. The culture media provides water to the growing cell. Thus, Option C (water) is correct.

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
