A group of tissues that are joined together to perform a specific function.

• cell

• tissue

• organ

• organ system

Answer explanation

An organ is a group of tissues that work together to perform a specific function, such as the heart or liver. In contrast, a cell is the basic unit of life, and a tissue is a group of similar cells, while an organ system is a group of organs.

Which of these is NOT an organ?

• nervous system

• heart

• liver

• brain

Answer explanation

The nervous system is a complex network of nerves and cells that transmit signals, but it is not classified as a single organ. In contrast, the heart, liver, and brain are all distinct organs with specific functions.

What is an organ system?

• The smallest unit of life

• A group of similar cells working together

• A group of tissues working together

• A group of organs working together in a self-contained system that is part of a larger system

Answer explanation

An organ system is defined as a group of organs working together in a self-contained system that is part of a larger system, such as the circulatory or digestive systems, which perform specific functions for the body.

Tissues that work together form -

• cells

• organs

• organisms

• organ systems

Answer explanation

Tissues are groups of similar cells that perform a specific function. When these tissues work together, they form organs, which carry out complex functions in the body. Therefore, the correct answer is 'organs'.

Which of these is the correct order of the levels of organization?

• cell, tissue, organ, organ system, organism

• organism, organ, organ system, tissue, cell

organs that work together form a ....

• organism

• organ system

Answer explanation

Organs that work together form an organ system, which is a group of organs that collaborate to perform specific functions in the body. An organism is a complete living entity, while an organ system is a component of that organism.

Something that has the necessary characteristics to allow specific functions to be performed

• system

• specialized

• organism
