Take in energy assimilation of materials respond to stimuli
Definite shape movement

Reproduction, growth, take in energy, assimilation of materials, respond to stimuli, movement.

The following are characteristics of living things:

Reproduction
Take in energy
Growth
Assimilation of materials
Respond to stimuli
Movement

To determine which of the listed characteristics are true for living things, we can break them down one by one:

1. Reproduction: This is a characteristic of living things, as they are capable of producing new organisms of the same kind.

2. Gas exchange: Living things require the exchange of gases, such as taking in oxygen and expelling carbon dioxide. This is true for many organisms, including humans, plants, and animals.

3. Growth: Living things have the ability to grow, both in size and in complexity. This can be seen in organisms as they develop from a single cell to a mature individual.

4. Take in energy: All living things require a source of energy to carry out their various life processes. This can be in the form of food or light, depending on the organism.

5. Assimilation of materials: Living things are capable of assimilating and utilizing the materials they take in for growth, repair, and other metabolic processes. They can break down complex substances into simpler ones to obtain the necessary nutrients.

6. Respond to stimuli: Living things can detect and respond to changes in their environment. This allows them to adapt and survive in different conditions.

7. Definite shape: While living things can have a distinctive shape, it is not necessarily a defining characteristic. Some organisms, such as certain types of microorganisms, can change shape depending on their environment.

8. Movement: Living things are capable of movement, either within their environment or through the ability to control their own internal structures.

Based on the explanations provided, the characteristics of living things are: Reproduction, Gas exchange, Growth, Take in energy, Assimilation of materials, Respond to stimuli, and Movement.
