ATI TEAS Science Questions
Question 1 of 5
What is the responsibility of the somatic nervous system?
Correct Answer: C
Rationale: The somatic nervous system is responsible for controlling voluntary movements of skeletal muscles. This system communicates sensory information and controls voluntary movements, such as walking or reaching for objects. Breathing is primarily regulated by the autonomic nervous system, which functions involuntarily. Thought processes involve complex interactions between various regions of the brain and are not directly controlled by the somatic nervous system. Fear is an emotional response that involves the limbic system of the brain and the autonomic nervous system, not the somatic nervous system.
Question 2 of 5
Which of the following structures acts like a funnel by delivering urine from the millions of collecting tubules to the ureters?
Correct Answer: A
Rationale: The correct answer is A: The renal pelvis. The renal pelvis serves as a reservoir for urine collected from the kidney's numerous collecting tubules, funneling it into the ureters for transport to the bladder. The renal cortex is the outer region of the kidney involved in filtration, while the renal medulla is the inner region responsible for concentrating urine. Bowman's capsule is part of the nephron and is involved in the initial filtration of blood in the kidney, not in funneling urine to the ureters.
Question 3 of 5
Which of the following is the body cavity that contains the urinary bladder, urethra, and ureters?
Correct Answer: B
Rationale: The correct answer is B, the pelvic cavity. The pelvic cavity houses organs related to the urinary and reproductive systems. The urinary bladder, urethra, and ureters are located in the pelvic cavity, making it the correct choice. The thoracic cavity contains the heart and lungs, while the abdominal cavity houses organs like the stomach and intestines. The spinal cavity, on the other hand, protects the spinal cord.
Therefore, options A, C, and D are incorrect as they do not house the specific organs mentioned in the question.
Question 4 of 5
Blood type is a trait determined by multiple alleles, with IA and IB being co-dominant: IA codes for A blood and IB codes for B blood, while i codes for O blood and is recessive to both. If an A heterozygote individual and an O individual have a child, what is the probability that the child will have A blood?
Correct Answer: B
Rationale: If an A heterozygote (IAi) and an O individual (ii) have a child, there is a 50% chance the child will inherit the IA allele and have A blood. The A heterozygote can pass on either the IA or i allele, while the O individual can only pass on the i allele.
Therefore, the possible genotypes for the child are IAi (A blood) or ii (O blood), resulting in a 50% chance of the child having A blood.
Choice A (25%) is incorrect as it does not take into account the possibility of inheriting the IA allele.
Choice C (75%) and
Choice D (100%) are incorrect as they overestimate the probability of the child having A blood.
Question 5 of 5
What is one feature that both prokaryotes and eukaryotes have in common?
Correct Answer: A
Rationale: The correct answer is A: A plasma membrane. Both prokaryotes and eukaryotes share the characteristic of having a plasma membrane that surrounds the cell. While eukaryotes also possess a nucleus enclosed by a membrane and various organelles, prokaryotes lack a nucleus and membrane-bound organelles. The plasma membrane, however, is a universal feature found in all cells, regardless of their classification as prokaryotic or eukaryotic.
Choice B is incorrect because only eukaryotes have a nucleus enclosed by a membrane.
Choice C is incorrect because prokaryotes have limited organelles compared to eukaryotes.
Choice D is incorrect as a nucleoid is a region in prokaryotic cells where the genetic material is located, not a common feature shared with eukaryotes.
