Compare and contrast protozoan cysts fungal spores and bacterial endospores
docker41 [41]

Bacterial spores or endospores are not for reproduction. They do not improve the total number of bacterial cells. Whereas for fungal spores, they are formed from aerial hyphae. They can either be asexual spores which when germinated will be a new but genetically identical to the parent. Sexual spores result from the combination or mixture of nuclei from two opposite mating strains of the same species.

During gym class, Raul walks briskly for a half hour. Jenna decides to sprint and run the bleachers for the same amount of time.
lbvjy [14]

Answer:

The correct answer would be Jenna’s cells are producing more lactic acid than Raul’s cells.

Workouts like sprints, bleachers, weight training et cetera come under the anaerobic zone of training.

They cause lack of oxygen in the muscles due to which muscles undergo lactic acid fermentation to produce energy (ATP).

Lactic acid fermentation converts one molecule of glucose into 2 molecules of lactic acid with a net gain of 2 ATP (as compared to 36-38 ATP produced in aerobic respiration).

Decreased efficiency in energy production leads to the utilization of more and more glucose or glycogen reserves of the muscles and lead to the accumulation of more and more lactic acid.
