Which of the following is a group that can be measured against the experimental group?

A. Manipulated

B. Responding

C. Variable

D. Control

Answer Explanation:

The experimental group is the group that receives the treatment or intervention in a scientific study. To evaluate the effect of the treatment, the experimental group is compared to another group that does not receive the treatment. This group is called the control group. The control group serves as a baseline or reference point for the experimental group. The control group should be as similar as possible to the experimental group in all other aspects, except for the treatment

Therefore, the Correct Answer is D.

Q #1: Which of the following can lead to a tsunami?

A. Lightning strikes

B. Flooding

C. Earthquakes

D. Sunspot activity

Answer Explanation

A tsunami is a series of large waves that are caused by the displacement of a large volume of water in the ocean or a large lake. The most common cause of tsunamis is earthquakes, which can generate seismic waves that travel through the water and create sudden changes in water level.
Q #2: Which of the following substances is responsible for donating H+ ions to act as a buffer when blood pH rises?

A. Carbon dioxide

B. Carbonic acid

C. Oxygen

D. Carbon monoxide

Answer Explanation

A buffer is a solution that can resist changes in pH when small amounts of acid or base are added. In the human body, blood is an important buffer that helps maintain a stable pH of about 7.4. One of the main components of the blood buffer system is the bicarbonate buffer, which involves the equilibrium between carbon dioxide (CO2), carbonic acid (H2CO3), and bicarbonate ions (HCO3-). When blood pH rises, meaning it becomes more basic, the bicarbonate buffer can donate H+ ions to lower the pH and restore the balance. The substance that donates H+ ions in this case is carbonic acid, which dissociates into H+ and HCO3-. Therefore,
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.
