Which product is made using bacteria a. the cheese on pizza b. the cork in a bulletin board c. the seaweed in sushi d. the latex in gloves

Option (A) is the correct answer.

Explanation:

Starter bacteria helps in conversion of milk sugars into lactic acid. This also helps in development of flavor in aged cheese that is used in many food items.

Most of the starter bacteria is made by using bacteria such as lactococcus and lactobacillus. Whereas initial cheese ripening is done by streptococci.

Thus, we can conclude that out of the given options cheese on pizza is the product which is made using bacteria.

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
