Biology

1. A population refers to a group of organisms of the same:

Correct answer: A

Rationale: In ecology, a population is a specific group of organisms of the same species living in a particular geographic area at a given time. They share a common gene pool and interact with each other and their environment.

2. The lymphatic system is primarily responsible for:

Correct answer: B

Rationale: The correct answer is B: 'Removing excess fluids and waste products from tissues.' The lymphatic system plays a crucial role in maintaining fluid balance in the body by collecting excess interstitial fluid and returning it to the bloodstream. This system also helps in removing waste products, pathogens, and toxins from tissues, contributing to the body's immune response. Options A, C, and D are incorrect because transporting nutrients, producing red blood cells, and regulating body temperature are primarily the functions of other systems in the body such as the circulatory system, bone marrow, and the thermoregulatory system, respectively.

3. The WBC (white blood cell) type responsible for the initial attack on pathogens is:

Correct answer: C

Rationale: The correct answer is C: Phagocytes. Phagocytes are a type of white blood cell that plays a crucial role in the immune response by engulfing and destroying pathogens. They are the first line of defense against invading microorganisms, initiating the initial attack on pathogens. Red blood cells (option A) are responsible for carrying oxygen, not for immune responses. Platelets (option B) are involved in blood clotting. Lymphocytes (option D) are another type of white blood cell but are mainly responsible for specific immune responses rather than the initial attack on pathogens.

4. What is the purpose of genetic counseling?

Correct answer: C

Rationale: To provide information and support to individuals and families with genetic risks. Genetic counselors explain the implications of genetic testing, discuss risks and options, and offer emotional and psychological support.

5. Which term refers to the measure of the mass of a substance per unit volume and is commonly expressed in kilograms per cubic meter?

Correct answer: c

Rationale: Density is the measure of the mass of a substance per unit volume and is commonly expressed in kilograms per cubic meter (kg/m³).

6. How does the mass of an object affect its inertia?

Correct answer: B

Rationale: Inertia is the resistance of an object to changes in its state of motion. The greater the mass of an object, the greater its inertia because it requires more force to change its state of motion. This is in line with Newton's first law of motion, which states that an object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an external force.
