The pleura is a connective tissue sheath that covers which of the following organs?

A. Lung

B. Heart

C. Spleen

D. Liver

Answer Explanation:

The pleura is a thin membrane that surrounds the lungs and lines the chest cavity. It protects the lungs from friction and infection, and helps them expand and contract during breathing. The other organs listed are not covered by the pleura, but by other types of connective tissue sheaths, such as the pericardium for the heart, the peritoneum for the spleen and liver, and the mesentery for the intestines.

Therefore, the Correct Answer is A.

  • Q #1:   The measurement indicated by the line across the center of the cell is best referred to as which of the following?

    A. Diameter

    B. Volume

    C. Area

    D. Radius

    Answer Explanation

    One way to assess the size of a cell is to measure its diameter, which is the length of a straight line that passes through the center of the cell and touches both sides. The measurement indicated by the line across the center of the cell in the diagram is best referred to as the diameter of the cell.

  • Q #2: Which of the following organic molecules contain both an amine and carboxyl group?

    A. Lipids

    B. Proteins

    C. Chitin

    D. Cellulose

    Answer Explanation

    An amine group is a nitrogen atom bonded to three hydrogen atoms, and a carboxyl group is a carbon atom double-bonded to an oxygen atom and single-bonded to a hydroxyl group. These groups are important for the formation of amino acids, which are the building blocks of proteins.

  • Q #3: Which of the following is the function of a totipotent cell?

    A. Aids in the maturation of sex cells

    B. Carries electrical impulses

    C. Develops into any kind of cell

    D. Fights infectious diseases

    Answer Explanation

    A totipotent cell is a type of stem cell that has the ability to develop into any kind of cell in the body, including the cells that make up the placenta and the umbilical cord. This means that a totipotent cell can generate a complete organism from a single cell. The only natural example of totipotent cells are the fertilized egg and the cells produced by the first few divisions of the egg. Totipotent cells are different from other types of stem cells, such as pluripotent cells, which can develop into any cell type except for the placenta and the umbilical cord, and multipotent cells, which can only develop into a limited range of cell types.
