Cathy placed a sample of yeast, a single-celled eukaryote, in a closed test tube containing a solution of glucose. How will the composition of the air in the test tube change as the yeast interacts with the glucose? A) The oxygen level will increase.
B) The carbon dioxide level will decease.
C) The carbon dioxide level will increase.
D) The level of carbon dioxide and oxygen will remain the same.

The level of carbon dioxide will increase.

•In the given case, yeast will go through the process of aerobic respiration and convert the glucose present into the usable energy form.

•The majority of the prokaryotes and eukaryotes utilize aerobic respiration to get the energy from glucose.

•In the process of aerobic respiration, the catabolism of glucose will occur, which will convert it into water, carbon dioxide, and energy.

•In the process, molecular oxygen is the ultimate electron acceptor.

•Therefore, in the given case, with the interaction of yeast with the glucose, the level of carbon dioxide in the test tube increases.

Thus, the correct answer is option C.

The answer is C

Explanation:

In the presence of oxygen, yeast undergo aerobic respiration and convert carbohydrates (sugar source) into carbon dioxide and water.

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.
