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

Q #1: Which of the following is the atomic number of an atom that has 12 protons and 12 neutrons?

A. 24

B. 1

C. 12

D. 144

Answer Explanation

The atomic number of an atom is defined as the number of protons in its nucleus. Protons are positively charged particles that make up part of the atomic mass, along with neutrons, which have no charge. The number of neutrons can vary for atoms of the same element, resulting in different isotopes. However, the number of protons is always constant for a given element. Therefore, to find the atomic number of an atom that has 12 protons and 12 neutrons, we only need to look at the number of protons.
Q #2: 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 #3: Which of the following microorganisms lack their own metabolic pathways and can only reproduce inside of a host cell?

A. Viruses

B. Bacteria

C. Helminths

D. Protozoa

Answer Explanation

Among the four types of microorganisms listed, only viruses lack their own metabolic pathways and can only reproduce inside of a host cell. Viruses are considered to be obligate intracellular parasites, meaning that they depend on another living cell for their survival and replication. Bacteria, helminths, and protozoa, on the other hand, are able to metabolize nutrients and energy from their surroundings and can reproduce independently of a host cell.
