TEAS 7 science quizlet

1. Differentiate between genotype and phenotype in the context of gene expression.

Correct answer: B

Rationale: - Genotype refers to the genetic makeup of an organism, including all the genes and alleles it possesses. - Phenotype, on the other hand, refers to the observable physical characteristics or traits of an organism, which result from the interaction between its genotype and the environment. - While genotype represents the genetic potential or range of traits that an organism can express, phenotype reflects the actual expression of specific traits. - Therefore, option B correctly captures the distinction between genotype and phenotype in the context of gene expression.

2. Based on the preceding words, what is the correct meaning of the suffix -fy in glorify, fortify, gentrify, acidify?

Correct answer: C

Rationale: The suffix '-fy' means to make or cause to have. Each word listed—glorify, fortify, gentrify, acidify—indicates a process of transforming or altering something, making the common meaning related to causing or making. Choice A ('Marked by, given to') is incorrect as it does not reflect the action of making or causing. Choice B ('Doer, believer') is unrelated to the suffix -fy and does not capture its meaning. Choice D ('Process, state, rank') is also incorrect as it does not align with the consistent theme of causing or making evident in the words provided.

3. How many lobes does the right lung have?

Correct answer: C

Rationale: The correct answer is C: 3. The right lung consists of three lobes: the upper, middle, and lower lobes. This distinction is vital as the left lung only has two lobes, the upper and lower lobes. Understanding the anatomical variances between the lobes of the right and left lungs is crucial for comprehending respiratory physiology and its clinical implications in medical practice. Choices A, B, and D are incorrect because the right lung does not have 1, 2, or 4 lobes. It is essential to differentiate between the lobes of the right and left lungs to have a comprehensive understanding of pulmonary anatomy.

4. What is 0.75 as a fraction?

Correct answer: A

Rationale: To convert a decimal to a fraction, you can write the decimal as a fraction with the decimal part as the numerator and a power of 10 as the denominator. In this case, 0.75 can be written as 75/100. Simplifying this fraction by dividing both the numerator and denominator by 25 gives you 3/4. Therefore, the correct answer is A. Choice B (7/10), Choice C (15/20), and Choice D (1/2) are incorrect because they do not represent the correct conversion of 0.75 into a fraction.

5. What type of bond forms between elements when they share electrons?

Correct answer: A

Rationale: The correct answer is A: Covalent bond. In a covalent bond, atoms share electrons, leading to the creation of a strong attraction that holds them together. This type of bond is characterized by the sharing of electron pairs between atoms, resulting in the formation of molecules. Choice B, Ionic bond, involves the transfer of electrons from one atom to another, creating charged ions that attract each other. Choice C, Metallic bond, refers to the sharing of electrons among a sea of delocalized electrons in a metal structure. Choice D, Hydrogen bond, is a weak electrostatic attraction between a hydrogen atom and an electronegative atom like oxygen or nitrogen, not involving the sharing of electrons.
