This quiz has been designed to help my students study for US 18969 Demonstrate knowledge of the characteristics of living things, organs and organ systems
- 1.
In biology a cell is ...
- A.
A square.
- B.
The basic unit of all living things.
- C.
The centre of an atom.
Correct Answer
B. The basic unit of all living things.Explanation
The correct answer is "the basic unit of all living things." This answer is correct because in biology, a cell is indeed considered to be the fundamental unit of life. Cells are the building blocks of all living organisms and are responsible for carrying out the essential functions necessary for life. They contain genetic material, perform metabolic processes, and are capable of self-replication. Therefore, understanding the structure and function of cells is crucial in understanding the complexity of living organisms.Rate this question:

An organ is made up of ...
- A.
tissues , e.g. a heart has smooth muscle tissue and cardiac muscle tissue.
- B.
Cells. The cells are just floating around in a disorganised way.
- C.
Muscle tissue.
Correct Answer
A. tissues , e.g. a heart has smooth muscle tissue and cardiac muscle tissue.Explanation
Organs are composed of different types of tissues that work together to perform specific functions. For example, the heart is made up of smooth muscle tissue and cardiac muscle tissue. These tissues have specialized cells that are organized in a specific way to allow the heart to contract and pump blood effectively. Therefore, the correct answer is that organs are made up of tissues.Rate this question:

Blood cells, nerve cells and brain cells are all examples of...
- A.
Cells and organs
- B.
Cells
- C.
Organ systems
Correct Answer
B. CellsExplanation
Blood cells, nerve cells, and brain cells are all examples of cells. Cells are the basic structural and functional units of living organisms. They are responsible for carrying out all the necessary processes for the organism's survival. Blood cells are involved in transporting oxygen and nutrients, nerve cells transmit electrical signals throughout the body, and brain cells are responsible for processing information and controlling bodily functions. Therefore, all these examples fall under the category of cells.Rate this question:

The brain is an example of an ___________ [choose from cell, organ, organ system]
Correct Answer
organExplanation
The brain is an example of an organ because it is a complex structure made up of different types of tissues that work together to perform specific functions. It is a vital part of the central nervous system and is responsible for controlling and coordinating various bodily activities, such as sensory perception, motor control, and cognitive processes. As an organ, the brain plays a crucial role in maintaining homeostasis and overall body functioning.Rate this question:

- B.
The circular system
- C.
The musculoskeletal system
- D.
The circulatory system
Correct Answer

A group of organs that have blood running through them
- C.
A group of organs that work together to perform a specific function
- D.
All the organs that make up one living organism
Correct Answer
C. A group of organs that work together to perform a specific functionExplanation
An organ system is a group of organs that work together to perform a specific function. This means that the organs within the system have a coordinated effort to carry out a particular task or purpose in the body. It is not simply a group of organs that look similar to each other or have blood running through them. Additionally, an organ system does not necessarily include all the organs that make up one living organism, as there can be multiple organ systems within a single organism.Rate this question:
