Bio Exam Practice Topic 14 Coordination and Response

Front

What is coordination in biological systems?

Back

Coordination refers to the process by which different parts of an organism work together to respond to internal and external stimuli.

Front

Define response in the context of biology.

Back

Response is the action or change in behavior of an organism as a result of a stimulus.

Front

What are the main components of the nervous system?

Back

The main components of the nervous system are the brain, spinal cord, and peripheral nerves.

Front

Explain the role of neurons in coordination and response.

Back

Neurons are specialized cells that transmit nerve impulses, allowing for communication between different parts of the body and facilitating coordination and response.

Front

What is a reflex action?

Back

A reflex action is an involuntary and immediate response to a stimulus, often mediated by the spinal cord.

Front

Describe the difference between voluntary and involuntary responses.

Back

Voluntary responses are conscious actions controlled by the brain, while involuntary responses occur automatically without conscious thought.

Front

What is the function of the endocrine system in coordination?

Back

The endocrine system regulates bodily functions through hormones, which are chemical messengers that coordinate activities across different organs.

Front

Define homeostasis.

Back

Homeostasis is the maintenance of a stable internal environment in an organism despite changes in external conditions.

Front

What is the role of the hypothalamus in coordination?

Back

The hypothalamus is a brain region that regulates many bodily functions, including temperature, hunger, and thirst, playing a key role in maintaining homeostasis.

Front

Explain the term 'stimulus' in biology.

Back

A stimulus is any change in the environment that can provoke a response from an organism.
