TEAS 7 science practice questions

1. Which part of the male reproductive system is responsible for producing seminal fluid?

Correct answer: C

Rationale: The correct answer is the prostate gland (Choice C). The prostate gland, located near the bladder, is responsible for producing seminal fluid. This fluid, along with sperm from the testes, makes up semen. The bladder stores urine, the urethra is a tube that carries urine from the bladder out of the body, and the kidney filters waste from the blood to produce urine. The prostate gland's specific function is to secrete a milky, alkaline fluid that mixes with sperm during ejaculation to form semen. This fluid helps nourish and protect the sperm, aiding in their motility and viability. Therefore, the prostate gland plays a crucial role in male reproductive function by contributing to the composition and quality of semen, essential for fertility.

2. The shimmering image of water seen on a hot road is a well-known example of:

Correct answer: B

Rationale: The shimmering image of water seen on a hot road is a result of refraction, not reflection. Refraction is the bending of light as it passes from one medium to another of different optical density. In this case, the hot air just above the road has a different density than the cooler air above it, causing light to bend and create the illusion of water on the road. Refraction is the most suitable explanation for this phenomenon, as it involves the bending of light rays due to the change in the medium's optical density, producing the visual effect observed on the hot road. Reflection, interference, and polarization do not involve the bending of light due to changes in optical density and are not applicable to the scenario described on the hot road.

3. Chyle, a milky white fluid, is transported by lymphatic vessels from the:

Correct answer: B

Rationale: Chyle, a milky white fluid, is formed in the small intestine during digestion. It is composed of lymph and emulsified fats. Lymphatic vessels in the intestines, specifically lacteals, transport chyle from the intestines to the bloodstream for the distribution of nutrients throughout the body. The transport of chyle from the lungs, kidneys, or skin is not correct as these organs are not primarily involved in the production or transportation of chyle.

4. Following the scientific method, which steps would be done before gathering qualitative data?

Correct answer: B

Rationale: In the scientific method, defining the problem is typically the initial step. Before gathering qualitative data, it is essential to clearly outline and understand the issue or question being addressed. This step helps in guiding the research process and ensures that the data collected are relevant to the problem at hand. Communicating with a scientific journal (Choice A) is not a standard step in the scientific method; it comes after the research is conducted. Developing a hypothesis (Choice C) usually follows defining the problem and precedes data collection. Categorizing data for statistical analysis (Choice D) occurs after data collection, not before gathering qualitative data.

5. Which property of matter refers to the amount of space occupied by an object and is measured in cubic units?

Correct answer: D

Rationale: Volume is the property of matter that refers to the amount of space occupied by an object. It is measured in cubic units, such as cubic meters or cubic centimeters. Mass, on the other hand, is the amount of matter in an object, weight is the force of gravity acting on an object, and density is the mass per unit volume of a substance. In this question, the key concept is the space occupied by an object, which directly relates to volume, making it the correct answer. Choices A, B, and C are incorrect as they do not specifically pertain to the amount of space occupied by an object.
