Which of the following organelles is the site of intracellular digestion?

A. Mitochondria

B. Lysosomes

C. Centrosomes

D. Ribosomes

Answer Explanation:

Lysosomes are membrane-bound organelles that contain lysozymes that are responsible for breaking down waste materials and cellular debris through intracellular digestion. This process helps maintain cellular health and homeostasis by recycling and degrading cellular components.

Therefore, the Correct Answer is B.

Q #1: Which of the following describes one difference between skeletal muscles and cardiac muscles?

A. Skeletal muscles are found in the viscera whereas cardiac muscles are found in the cranium

B. Cardiac muscles contain intercalated discs, whereas skeletal muscles do not

C. Cardiac muscles are voluntary, whereas skeletal muscles are involuntary

D. Skeletal muscles are autorhythmic, whereas cardiac muscles are not

Answer Explanation

Cardiac muscles have intercalated discs that enable them to contract in a coordinated manner. Skeletal muscles do not have intercalated discs, as their contraction is under voluntary control and does not require the same level of synchronization seen in the involuntary contraction of cardiac muscle.
Q #2: In order to determine the effects of energy drinks on women's running speed, researchers gave 300 women an energy drink and then recorded the time it took each of them to run 2 miles. After collecting the results, researchers concluded that energy drinks increase the speed of running in Which of the following further tests would best help to support this conclusion?

A. Repeat the same experiment, using 300 men

B. Repeat the experiment giving half of the women water and the other half the energy drink

C. Repeat the experiment giving the women two different energy drinks

D. Repeat the experiment, having half of the women run 2 miles and the other half run 5 miles

Answer Explanation

Conducting the experiment with half the women taking water and the other half taking an energy drink creates a study and experimental group, which can allow for comparison and conclusion. The researchers can compare the effects of the energy drink directly with a baseline, and this helps to establish a cause-and-effect relationship and provides stronger evidence to support their conclusion.
Q #3: The hip is an example of which of the following type of joints?

A. Ball-and-socket

B. Pivot

C. Gliding

D. Hinge

Answer Explanation

The hip joint is an example of a ball-and-socket joint. The hip joint is formed by the articulation of the head of the femur with the acetabulum of the pelvis. The rounded head of the femur (ball) fits into the cup-shaped acetabulum (socket), allowing for a wide range of motion in multiple planes.
