TEAS Test 7 science quizlet

1. What is the muscular sac in the female body that nourishes and protects a developing fetus during pregnancy?

Correct answer: C

Rationale: The correct answer is the uterus. The uterus is a muscular organ in the female body where a developing fetus is nourished and protected during pregnancy. It is the site where a fertilized egg implants and grows into a fetus. The ovaries produce eggs, the fallopian tubes transport the egg to the uterus for potential fertilization, and the vagina serves as the birth canal and the passage for menstrual blood to exit the body. Therefore, the uterus plays a crucial role in pregnancy by providing a nurturing environment for the developing fetus.

2. Which type of energy is possessed by an object due to its position or configuration?

Correct answer: C

Rationale: Potential energy is the energy that an object possesses due to its position or configuration. It is considered stored energy that can be converted into other forms of energy to do work. When an object is lifted against gravity or compressed, it gains potential energy. Kinetic energy, the incorrect choice A, is the energy of motion possessed by an object. Thermal energy, the incorrect choice B, is related to the temperature of an object due to the motion of its particles. Electrical energy, the incorrect choice D, is related to the flow of electric charge in a circuit or system. Therefore, the correct answer is potential energy as it is associated with an object's position or configuration.

3. Which of the following contains a single immature egg cell that is released during ovulation?

Correct answer: B

Rationale: Follicles are the structures in the ovaries that contain the oocytes (immature egg cells). During ovulation, a single mature egg cell is released from a mature follicle in the ovary. The other options (A. oocytes, C. ovaries, D. fallopian tubes) do not specifically refer to the structure that contains the immature egg cell that is released during ovulation.

4. The resolution of an optical instrument, like a microscope, refers to its ability to distinguish between:

Correct answer: D

Rationale: The resolution of an optical instrument, such as a microscope, refers to its ability to distinguish between very close, nearly identical objects. This is crucial in microscopy to clearly visualize and differentiate fine details and structures. Resolving power plays a significant role in determining the quality and effectiveness of an optical instrument. Choices A, B, and C are incorrect because the resolution of an optical instrument does not primarily deal with different colors of light, presence or absence of light, or variations in intensity. Instead, it specifically focuses on the instrument's ability to differentiate between objects that are very close and nearly identical in nature.

5. Which hormone is responsible for milk production in the breasts after childbirth?

Correct answer: B

Rationale: Prolactin is the hormone responsible for milk production in the breasts after childbirth. It is produced by the pituitary gland and stimulates the mammary glands to produce milk. Estrogen aids in the development of breast tissue during pregnancy but is not directly involved in milk production. Oxytocin is responsible for milk ejection during breastfeeding, while Relaxin helps relax uterine muscles during pregnancy but is not directly linked to milk production.
