Mometrix TEAS 7 science practice test Questions
Question 1 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 2 of 5
Which type of symbiosis benefits both organisms from the interaction?
Correct Answer: A
Rationale: The correct answer is 'Mutualism.' Mutualism is a type of symbiosis where both organisms involved benefit from the interaction. This relationship is characterized by cooperation and mutual support, leading to advantages for both parties. In mutualistic relationships, each organism provides something that the other needs, resulting in a mutually beneficial outcome. In contrast, 'Commensalism' (choice B) involves one organism benefiting while the other is unaffected, 'Parasitism' (choice C) benefits one organism at the expense of the other, and 'Predation' (choice D) benefits the predator while harming the prey. Examples of mutualism include the relationship between bees and flowers (pollination) and the partnership between nitrogen-fixing bacteria and leguminous plants.
Question 3 of 5
What is the main difference between a telescope and a microscope?
Correct Answer: A
Rationale: The main difference between a telescope and a microscope lies in their primary functions. Telescopes are specifically designed to magnify and observe distant objects like stars, planets, and galaxies, making them essential tools for astronomy. In contrast, microscopes are utilized to magnify and study small objects such as cells, bacteria, and other microscopic organisms in fields like biology and medicine. Therefore, the key distinction is that telescopes focus on magnifying distant objects, while microscopes are tailored for magnifying small objects. Choice B is incorrect because while some microscopes may use mirrors in certain designs, the primary component is typically lenses. Choice C is incorrect as telescopes collect and focus light for observation, while microscopes use light to illuminate and magnify objects. Choice D is incorrect because while both instruments magnify objects, their main purposes and the types of objects they focus on are distinctly different.
Question 4 of 5
Which structure contains the genetic material (DNA) of the cell?
Correct Answer: B
Rationale: The nucleus is the organelle that contains the genetic material (DNA) of the cell. It acts as the control center of the cell, regulating gene expression and coordinating cellular activities. The cytoplasm is the fluid-filled space within the cell where organelles are suspended, but it does not contain the genetic material. The cell wall is a rigid structure found in plant cells that provides support and protection, but it does not house the DNA. The Golgi apparatus is involved in processing and packaging proteins for secretion, but it does not contain the genetic material of the cell.
Question 5 of 5
What is the functional group present in aldehydes?
Correct Answer: B
Rationale: The correct answer is B: Carbonyl. Aldehydes contain the functional group -CHO, which is a carbonyl group where a carbon atom is double-bonded to an oxygen atom and single-bonded to a hydrogen atom. This distinguishes aldehydes from other functional groups. Choice A, Hydroxyl (-OH), is not characteristic of aldehydes as it is found in alcohols. Choice C, Ester (-COOR), and choice D, Amine (-NH2), represent different functional groups not typically found in aldehydes. Therefore, the correct functional group present in aldehydes is the carbonyl group.
