TEAS 7 science quizlet

1. What is the process of converting DNA into a protein called?

Correct answer: B

Rationale: Translation is the correct answer. It is the process of converting the information in mRNA into a sequence of amino acids to form a protein. Transcription (Choice A) is the process of copying a segment of DNA into RNA. Replication (Choice C) is the process of making an identical copy of DNA. Mutation (Choice D) refers to a change in the DNA sequence that can lead to variations in proteins, but it is not the process of converting DNA into a protein.

2. Which of the following is the antiparticle of a neutron?

Correct answer: C

Rationale: The antiparticle of a neutron is an antineutron, which is composed of an antiproton and an antineutrino. The antineutrino (choice A) is not the antiparticle of a neutron. A positron (choice B) is the antiparticle of an electron, not a neutron. An electron (choice D) is a fundamental particle, not an antiparticle. Therefore, the correct answer is an antiproton (choice C), as it forms an antineutron when combined with an antineutrino.

3. Which of Mendel's Laws states that alleles for a gene segregate during gamete formation?

Correct answer: B

Rationale: The Law of Segregation, proposed by Gregor Mendel, states that alleles for a gene segregate during gamete formation. This means that each parent passes on only one allele for each gene to their offspring. This law explains how genetic diversity is maintained and how different combinations of alleles are generated in offspring. The Law of Independent Assortment (option A) is not the correct answer as it states that alleles of different genes assort independently of each other during gamete formation, not specifically alleles of a single gene. The Law of Dominance (option C) is incorrect as it pertains to the expression of alleles rather than their segregation during gamete formation. The Law of Probability (option D) is also incorrect as it is a general concept describing the likelihood of events, not specifically related to alleles segregating during gamete formation.

4. Which of the following organs is NOT directly involved in the mechanical breakdown of food?

Correct answer: D

Rationale: The correct answer is the esophagus (D). The esophagus is not directly involved in the mechanical breakdown of food. Its primary function is to transport food from the mouth to the stomach through peristalsis, a series of muscular contractions. The mouth is involved in the initial mechanical breakdown by chewing and mixing food with saliva. The stomach mechanically breaks down food through churning movements, and the small intestine further breaks down food through peristalsis and segmentation. Choices A, B, and C are directly involved in mechanical breakdown processes. The mouth helps in chewing and mixing food with saliva, the stomach mechanically breaks down food through churning movements, and the small intestine continues the breakdown process with peristalsis and segmentation.

5. What is the term for the inflammation of the airways in the lungs, often causing wheezing and difficulty breathing?

Correct answer: C

Rationale: Asthma is a chronic respiratory condition characterized by inflammation of the airways in the lungs, leading to symptoms such as wheezing, shortness of breath, chest tightness, and coughing. Pneumonia is an infection in the lungs caused by bacteria, viruses, or fungi, leading to symptoms like fever, cough, and difficulty breathing. Emphysema is a type of chronic obstructive pulmonary disease (COPD) characterized by damage to the air sacs in the lungs, resulting in shortness of breath and a chronic cough. Pleurisy, on the other hand, is inflammation of the lining around the lungs, causing chest pain that worsens with breathing or coughing. Therefore, the correct term for the inflammation of the airways in the lungs with symptoms of wheezing and difficulty breathing is Asthma.
