Quizlet Vocabulary HESI A2

1. What does 'Cease' mean?

Correct answer: B

Rationale: The correct answer is B: 'Come to an end.' Cease means to stop or come to an end. Choice A, 'Start,' is the opposite of what Cease means. Choice C, 'Pause,' implies a temporary stop, which is not the same as coming to an end. Choice D, 'Skip,' means to omit or bypass, which is different from the meaning of Cease.

2. Which of these types of intermolecular force is weakest?

Correct answer: B

Rationale: The correct answer is B, London dispersion force. London dispersion forces are the weakest type of intermolecular force among the options provided. These forces arise from temporary fluctuations in electron distribution within molecules, leading to temporary dipoles. London dispersion forces are present in all molecules and are generally weaker than dipole-dipole interactions, hydrogen bonding, and ionic bonding. Dipole-dipole interactions are stronger than London dispersion forces as they involve permanent dipoles in molecules. Hydrogen bonding is stronger than both London dispersion and dipole-dipole interactions as it is a special type of dipole-dipole interaction that occurs when hydrogen is bonded to highly electronegative atoms like oxygen or nitrogen. Ionic bonding is the strongest type of intermolecular force among the options, but it is not the correct answer for the weakest type of force.

3. What provides the cell with the ability to move and propel?

Correct answer: B

Rationale: Microtubules are the cellular structures responsible for cell movement and propulsion. Microtubules are part of the cytoskeleton and play a crucial role in various cellular processes, including cell motility and intracellular transport. While microfilaments also contribute to cell movement by enabling muscle contraction and cell shape changes, they are not primarily responsible for propelling the cell. Flagella and cilia are cellular appendages involved in cell movement, but they are composed of microtubules, making them the structures that move due to the actions of microtubules.

4. Which is true of the term Phenotype?

Correct answer: D

Rationale: The term "phenotype" refers to the observable characteristics or traits of an organism, which are determined by a combination of genotype (genetic makeup), epigenetic factors (modifications to gene expression), and environmental factors (external influences and experiences). Genotype, epigenetic factors, and environmental factors all play a role in determining an individual's phenotype, making option D the correct statement. Options A, B, and C are incorrect because the phenotype is not the genetic code, the phenotype does not determine the genotype, and it is the genotype that influences the phenotype, not the other way around.

5. Choose the meaning of the word 'contusions' in the following sentence: 'Contusions or scratches may be treated on-site.'

Correct answer: C

Rationale: The correct answer is C: 'Bruises.' In the context of the sentence provided, 'contusions' refers to injuries that cause discoloration or bruising of the skin without breaking the skin. The word 'contusions' is synonymous with bruises, not breaks (choice A), disorientation (choice B), or abrasions (choice D). Therefore, in the sentence, contusions or scratches are mentioned as potential injuries that may require treatment on-site.
