Please help I wasn't paying attention. I'll MARK THE BRAINLIEST. Choose THREE: What is the THREE roles/functions of the nervous system?
A.) Receiving information
B.) Responding to information
C.) Maintaining homeostasis
D.) Transforming food into energy for the body

2.) TRUE/FALSE: You can move without your nervous system.

B.) False

3.) TRUE/FALSE: All nervous system responses are voluntary or under your control.
A.) True
B.) False

4.) A change or signal in the environment that makes the nervous system react is called a:

5.) If you touched a hot object, what would the stimulus be?

6.) If you touched a hot object, what would the response be?

7.) Give an example of a stimulus and describe your body's response.

1. a,b and c

2. false

3. false

3. Stimulus

4. Receptor in the skin detects a stimulus (the change in temperature). Sensory neuron sends impulses to relay neuron. Motor neuron sends impulses to effector.

5. skin receptors quickly send nerve impulses (electrical) to the spinal cord (central nervous system) via sensory neurons

6.  tropism, in plants is phototropism (or light response). Plants grow towards light sources, and if the direction of light is changed, the plant will also change its direction of growth to accommodate for survival.

A,B,C

FALSE

The ringing of a telephone prompts to answer a call.

Explanation:

The sensory neurons found in the receptor organ ( which is the ear ) will detect the ringing of the telephone, and will therefore transmit a nervous message to the central nervous system .The brain interprets the nervous message , and then sends a message through the motor neurons to the effector organ , which in turn will respond by answering the call .

economic impact of malaria is estimated to cost africa $12 billion every year. this figure factors in costs of health care, absenteeism, days lost in education, decreased productivity due to brain damage from cerebral malaria, and loss of investment and tourism.
