Propionibacterium a. produces propionic acid. b. produces lactic acid. c. is responsible for the holes in swiss cheese. d. requires aerobic environments. e. produces propionic acid and is responsible for the holes in swiss cheese.

E. produces propionic acid AND is responsible for the holes in Swiss cheese.

Explanation:

Propionibacterium is an anaerobic bacteria that perform fermentation for energy production. Propionibacterium converts the lactic acid into pyruvic acid.

The pyruvic acid enters the Kreb's cycle resulting in the formation of propionic acid and CO2. The carbon dioxide gas formed during the process imparts holes to the Swiss Cheese during its ripening process.

correct answer: biotic and abiotic limitations

carrying capacity is defined as the total number of an organism who can be supported in a given area within the natural resources limit and without harming or degrading the natural, economic or the cultural environment present for the future generations.

carrying capacity is determined by the limiting factors, which are known to affect the natural resources available. it may include water, nutrients, minerals, space, light etc.

explanation:

hope this ! have a wonderful day!

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
