ATI TEAS Science Test Questions

Question 1 of 5

What is the control, if any, in this experiment?

Correct Answer: B

Rationale: The correct answer is B: 'The control is the water.' In a scientific experiment, the control group is used as a baseline comparison to evaluate the effects of the variables being tested. Here, the water serves as the control group against which the effects of other substances like diet soda or different amounts of sunlight can be compared. Choice A is incorrect as every experiment should have a control group for comparison. Choice C and D are incorrect as they are not the standard control in this scenario.

Question 2 of 5

What is correct about the hormones that stimulate male and female organs to produce male and female sex hormones?

Correct Answer: C

Rationale: The correct answer is C. The same hormones stimulate both male and female organs to produce sex hormones. Hormones such as luteinizing hormone (LH) and follicle-stimulating hormone (FSH) are produced by the pituitary gland and act on the ovaries in females and the testes in males to stimulate the production of sex hormones (estrogen and progesterone in females, testosterone in males). Therefore, the same hormones stimulate both male and female organs to produce sex hormones. Choices A, B, and D are incorrect because they do not accurately describe the relationship between hormones and the stimulation of male and female organs to produce sex hormones.

Question 3 of 5

What are groups of cells that perform the same function called?

Correct Answer: A

Rationale: Groups of cells that perform the same function are called tissues. Tissues are composed of a group of similar cells working together to carry out specific functions within an organism. Each type of tissue has a specialized structure that enables it to perform its specific role effectively. Plastids are cell organelles found in plants responsible for functions like photosynthesis and storage, not groups of cells. Organs are composed of different types of tissues working together. Molecules are made up of atoms and are not groups of cells.

Question 4 of 5

The adrenal glands are part of the

Correct Answer: B

Rationale: The correct answer is B: endocrine system. The adrenal glands are part of the endocrine system. These small, triangular-shaped glands are located on top of each kidney and are responsible for producing hormones such as adrenaline, cortisol, and aldosterone. These hormones play a vital role in regulating various body functions, including metabolism, immune response, and stress response. Choices A, C, and D are incorrect because the adrenal glands are not part of the immune system, lymphatic system, or respiratory system. While the immune system is involved in protecting the body from infections and diseases, the lymphatic system helps in maintaining fluid balance and immune function, and the respiratory system is responsible for breathing and gas exchange in the body.

Question 5 of 5

How many tissue layers make up the uterus?

Correct Answer: C

Rationale: The correct answer is C, 'Three.' The uterus is composed of three tissue layers: the endometrium, myometrium, and perimetrium. The endometrium is the innermost layer that thickens during the menstrual cycle and sheds during menstruation or supports a developing embryo during pregnancy. The myometrium is the middle layer, consisting of muscle tissue that contracts during labor. The perimetrium is the outer layer that covers the uterus. These three layers work together to support the functions of the uterus, such as menstruation, pregnancy, and labor. Choices A, B, and D are incorrect because the uterus is not made up of just one or two layers but rather three distinct tissue layers.
