TEAS Test 7 science quizlet Questions

Question 1 of 5

What is the main factor limiting population growth in K-strategists?

Correct Answer: B

Rationale: K-strategists are species with a low reproductive rate that invest more resources in raising fewer offspring. These species typically live in stable environments with limited resources. The main factor limiting population growth in K-strategists is the availability of resources such as food, shelter, and space. When resources are scarce, K-strategists may struggle to find enough to support their population size, leading to reduced reproductive success and population growth. While predation, competition, and disease can also impact population growth, the primary limiting factor for K-strategists is the availability of resources.

Question 2 of 5

Which of the following is NOT true about fossils?

Correct Answer: D

Rationale: A) This statement is true. Fossils can provide evidence for the order of appearance of different species through the study of the fossil record. B) This statement is true. Fossils can be used to estimate the age of rocks and layers through relative dating methods such as stratigraphy and absolute dating methods like radiometric dating. C) This statement is true. Fossils can provide information about the behavior of extinct organisms through the study of their preserved remains and traces. D) This statement is NOT true. Fossils are not always perfectly preserved. In many cases, fossils are incomplete, fragmented, or altered over time due to geological processes. The level of preservation can vary depending on factors such as the type of organism, the environment in which it lived, and the processes involved in fossilization.

Question 3 of 5

How can the periodic table be used to predict the charge of an ion formed by an element?

Correct Answer: B

Rationale: The group number of an element on the periodic table corresponds to the number of valence electrons it has. Elements in the same group tend to form ions with the same charge. For example, elements in Group 1 typically form ions with a +1 charge, while elements in Group 17 typically form ions with a -1 charge. Therefore, by identifying the group number of an element, one can predict the typical ionic charge it will form. Choices A, C, and D are incorrect because predicting the charge of an ion is mainly based on the element's position in the periodic table, particularly the group number, which indicates the number of valence electrons and the typical ionic charge it may form.

Question 4 of 5

What is the scientific term for a broken bone?

Correct Answer: B

Rationale: The scientific term for a broken bone is a fracture. Osteoporosis is a condition characterized by weak and brittle bones, not a broken bone. A sprain involves an injury to a ligament, not a bone. Dislocation occurs when the ends of bones are forced out of their normal positions at a joint, which is different from a fracture.

Question 5 of 5

Which term in physics describes the resistance of an object to changes in its motion?

Correct Answer: A

Rationale: Inertia is the term that describes the resistance of an object to changes in its motion. This property is explained by Newton's First Law of Motion, which states that objects tend to maintain their state of motion unless acted upon by an external force. Inertia is closely related to mass, where objects with more mass exhibit more resistance to changes in motion. Momentum (B) is the product of an object's mass and velocity, gravity (C) is the force of attraction between objects, and kinetic energy (D) is the energy associated with an object's motion. Therefore, the correct answer is A because inertia specifically addresses the resistance of an object to changes in its motion.
