Homeostasis: $\text{Internal Environment} = \text{Relatively Constant}$

Question 1

Which of the following best describes inductive reasoning in scientific investigation?

Accepted Answer

It accumulates facts through observation to form general principles.

Question 2

A scientist observes that all known living things are composed of cells. She then proposes that any newly discovered organism will also be made of cells. Which type of reasoning is she using?

Accepted Answer

Inductive reasoning

Question 3

Which of the following is NOT a characteristic of living things according to the study materials?

Accepted Answer

They do not maintain homeostasis.

Question 4

A patient’s body temperature rises above normal and triggers mechanisms that bring it back down. This process is an example of:

Accepted Answer

Homeostasis

Question 5

Which of the following statements about deductive reasoning is correct?

Accepted Answer

It starts with a general statement and leads logically to one or more conclusions.

Question 6

Red blood cells and white blood cells differ in shape. Which of the following best describes their shapes?

Accepted Answer

Red blood cells are disks; white blood cells are spheres.

Question 7

Which of the following equations best represents the concept of homeostasis in a living organism?

Accepted Answer

Homeostasis: $	ext{Internal Environment} = 	ext{Relatively Constant}$

Question 8

Which of the following is a direct result of populations evolving over time?

Accepted Answer

Organisms adapt to their environment.

Question 9

In the classification system described, which is the correct hierarchy from broadest to most specific?

Accepted Answer

Domains > Kingdoms

Question 10

A biologist groups organisms based on evolutionary relationships. Which principle is she applying?

Accepted Answer

Classification

Question 11

Which of the following scenarios best illustrates the use of deductive reasoning in anatomy and physiology?

Accepted Answer

Starting with the principle that all cells require energy and deducing that red blood cells must have mechanisms to obtain energy.

Question 12

Which of the following is a plausible consequence if an organism fails to maintain homeostasis?

Accepted Answer

It may experience dysfunction or disease.

Question 13

Which of the following best describes the relationship between metabolism and energy in living organisms?

Accepted Answer

Metabolism is the process by which organisms use energy and raw materials.

Question 14

A scientist uses the following logic: 'All living things are composed of cells. This organism is living. Therefore, it is composed of cells.' Which reasoning method is used?

Accepted Answer

Deductive reasoning

Question 15

Which of the following is a multi-step process that integrates both metabolism and homeostasis?

Accepted Answer

Cells use energy to carry out metabolism, producing heat, which is regulated to maintain a constant internal temperature.

Question 16

Which of the following best explains why organisms with the greatest similarity are grouped together in classification systems?

Accepted Answer

They share evolutionary relationships.

Question 17

Which of the following is a correct application of inductive reasoning in anatomy and physiology?

Accepted Answer

Observing that all known cells have membranes and concluding that cell membranes are a universal feature.

Question 18

Which of the following is a plausible distractor for the equation representing homeostasis?

Accepted Answer

Homeostasis: $	ext{Internal Environment} = 	ext{Always Changing}$

Question 19

Which of the following is NOT a domain in the classification system described?

Accepted Answer

Animalia

Question 20

A medical case involves a patient whose white blood cells are abnormally shaped. Which of the following best describes the normal shape of white blood cells?

Accepted Answer

Spheres
