ATI TEAS Science Questions
Question 1 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 2 of 5
In a closed system with a gas at constant volume, what will happen to the temperature if the pressure is increased?
Correct Answer: C
Rationale: In a closed system with a gas at constant volume, according to Gay-Lussac's law, the temperature of a gas is directly proportional to its pressure. When the pressure is increased, the temperature of the gas will also increase. This relationship is a direct consequence of the ideal gas law, where pressure and temperature are directly proportional when volume is held constant.
Therefore, as pressure increases in a closed system with constant volume, the temperature of the gas will increase.
Choices A, B, and D are incorrect. The temperature will not stay the same (
Choice
A) or decrease (
Choice
B) when the pressure is increased in this scenario. The relationship between pressure and temperature in a closed system with constant volume allows for a definitive conclusion about the increase in temperature when pressure is increased, making
Choice D, which suggests inability to determine, incorrect.
Question 3 of 5
Which of the following is a cluster of capillaries that functions as the main filter of the blood entering the kidney?
Correct Answer: C
Rationale: The correct answer is C, the glomerulus. The glomerulus is a cluster of capillaries in the kidney responsible for filtering blood as it enters the nephron. It plays a crucial role in the initial stages of urine formation by filtering waste products and excess substances from the blood.
Choice A, the Bowman's capsule, is incorrect as it surrounds the glomerulus and captures the filtrate.
Choice B, the Loop of Henle, is incorrect as it is part of the nephron responsible for water reabsorption.
Choice D, the nephron, is incorrect as it comprises the functional unit of the kidney and includes the glomerulus, Bowman's capsule, and other structures.
Question 4 of 5
What is an alteration in the normal gene sequence called?
Correct Answer: A
Rationale: A DNA mutation is the correct term used to describe an alteration in the normal gene sequence. It refers to changes in the DNA sequence that can result in different traits or characteristics. Gene migration involves the movement of genes between populations, polygenic inheritance refers to the inheritance of traits controlled by multiple genes, and incomplete dominance is a pattern of inheritance where neither allele is dominant.
Question 5 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.
