Options:

A. This option is wrong because the number of bubbles at this temperatures is low, maybe the enzyme is already denatured.

B. This answer is wrong, at 30°C the enzyme shows a low activity.

C. This answer is correct because at this temperature the enzyme produces the higher amount of bubbles.

D. The activity of the enzyme at 0°C was not tested.

• Green algae grow on objects that do not move such as substrate, rock.

• Brown algae - wide distribution from tropical to polar zones.

DIFFERENCES BETWEEN REPRODUCTION.

• Cyanobacteria - asexually by binary or multiple fission, fragmentation, spore formation.

• Diatom - asexually by cell division through mitosis.

• Coccolithophores - asexually by binary fission.

• Silicoflagellates - asexually

• Dinoflagellates - asexually
