Question 1

Identify all answer choices that best complete the question. Which of the following are necessary for energy production within the mitochondria of a cell?

Accepted Answer

Lysosomes are cellular organelles involved in digestion and recycling of cellular waste. While important for overall cellular function, they are not necessary for energy production within mitochondria. Glucose and oxygen, on the other hand, are both essential components for the process of cellular respiration that occurs within mitochondria, ultimately leading to the production of ATP (adenosine triphosphate) energy molecules. Proteins are also important for various cellular processes, but are not specifically necessary for energy production within mitochondria.

Question 2

Identify all answer choices that best complete the question. The ability of an organism to cause infection is determined by:

Accepted Answer

All of the choices contribute to an organism's ability to cause infection. Virulence describes the severity of the disease caused by an organism. The portal of entry determines where the organism enters the body and can affect the severity of infection. The host's immune system can prevent or limit infection, while the number of organisms can impact the initial infection and potential for spread.

Question 3

Phagocytes are both mobile and found in fixed locations throughout the body.

Accepted Answer

Phagocytes are a type of immune cell that can be found in both mobile and fixed locations throughout the body. Examples of phagocytes include macrophages and neutrophils, which can move around in the bloodstream and tissues, as well as dendritic cells, which are found in specific organs like the skin and intestines.

Question 4

Identify all answer choices that best complete the question. Which of the following statements are true regarding cell-mediated immune response?

Accepted Answer

T-cells play a key role in cell-mediated immune response, which protects against viruses and fungi.

Question 5

Identify all answer choices that best complete the question. The adaptive immune response includes:

Accepted Answer

The adaptive immune response includes the cell-mediated immune response and the humoral immune response. The innate immune response is not a part of the adaptive immune response, and while the antigen immune response is important for the adaptive immune response, it is not a separate component of it.

Question 6

Identify all answer choices that best complete the question. Which of the following are "kingdoms" used for classification of living organisms?

Accepted Answer

The three kingdoms used for classification of living organisms are Animalia (animals), Plantae (plants), and Protista (protists). Microbes can be found in multiple kingdoms, including bacteria, archaea, and some protists. Therefore, option A is not a correct answer.
