Question 1 of 5

What is the relationship between mass and weight on Earth's surface?

Correct Answer: C

Rationale: The correct answer is C: Weight is greater than mass. Mass is a measure of the amount of matter in an object, while weight is the force of gravity acting on that object. On Earth's surface, weight is greater than mass because gravity pulls objects towards the center of the Earth, resulting in a force that we perceive as weight. Choice A is incorrect because mass and weight are not equal; weight is a force, while mass is a measure of the amount of matter. Choice B is incorrect because mass is not greater than weight; weight is the force exerted due to gravity. Choice D is incorrect as mass and weight are related; weight is dependent on mass and the gravitational force acting on the object.

Question 2 of 5

Which of the following is a functional group commonly found in alcohols?

Correct Answer: B

Rationale: The hydroxyl functional group (OH) is commonly found in alcohols, giving them their characteristic properties. Alcohols are organic compounds that contain a hydroxyl group bonded to a carbon atom. The other choices, carbonyl, amine, and ester, are associated with different functional groups commonly found in other types of organic compounds. Carbonyl groups consist of a carbon atom double-bonded to an oxygen atom. Amines contain a nitrogen atom bonded to hydrogen atoms. Esters consist of a carbonyl group bonded to an alkoxyl group. Therefore, the correct answer is 'Hydroxyl (B),' as it specifically relates to the functional group present in alcohols, distinguishing it from the other options.

Question 3 of 5

What functional group is present in esters?

Correct Answer: C

Rationale: The functional group present in esters is -COO-, which represents a carbonyl group bonded to an oxygen atom. This group is responsible for the characteristic fruity aroma of esters. Choice A, 'Hydroxyl,' refers to -OH, which is a characteristic group of alcohols, not esters. Choice B, 'Carbonyl,' is a broad term that includes various compounds with a C=O group, but specifically in esters, it is a carbonyl group bonded to an oxygen atom. Choice D, 'Amine,' refers to compounds containing a nitrogen atom bonded to hydrogen atoms or alkyl groups, which is not present in esters. Therefore, the correct answer is 'C: Ester.'

Question 4 of 5

Which of the following is an example of a zoonotic disease?

Correct Answer: B

Rationale: A zoonotic disease is a disease that can be transmitted from animals to humans. Influenza is an example of a zoonotic disease as it can be transmitted from animals such as birds and pigs to humans. The common cold (option A) is caused by human rhinoviruses and is not considered a zoonotic disease. Malaria (option C) is transmitted through the bite of infected mosquitoes and is not considered a zoonotic disease. HIV/AIDS (option D) is caused by the human immunodeficiency virus and is not considered a zoonotic disease.

Question 5 of 5

Which muscle type is characterized by a combination of voluntary and involuntary control, is striated, and is responsible for pumping blood throughout the circulatory system?

Correct Answer: C

Rationale: The correct answer is C, Cardiac muscle. Cardiac muscle is characterized by a combination of voluntary and involuntary control, is striated, and is responsible for pumping blood throughout the circulatory system. Skeletal muscle is primarily under voluntary control, smooth muscle is primarily under involuntary control, and connective tissue is not a muscle type, but rather provides support and structure to the body.
