When we did the 'Can You Feel The Difference' activity, the one-point touches acted as a ​ (a)   or the data we collected that was used to compare with our experimental data.

• control
• experimental
• variable
• constant
• dependent variable

Answer explanation

When we do an experiment, we always want to control some data so that we can compare it to the experimental results.

The part of an experiment that can change is known as a(n)

• variable

• constant

• experiment

• placebo

Answer explanation

For example, one variable in the 'Can You Feel This' activity was the number of points we used on the sensor.

A portion of a reflex is represented in the diagram. The function of structure A is to

• create neurotransmitters

• detect changes in the environment

• carry messages away from the central nervous system

• act as a motor neuron

Two types of human cells are shown in the diagram. Cell A causes the cells at B to contract. This activity would be most useful for

• lifting a book from a bookshelf

• control the functions of a cell

• digesting food in the small intestine

A blind student runs his fingers along a page of braille. Another student reads a page printed in a textbook. Both students are able to obtain and process the information most directly as a result of the activities of the

• sensory neurons and cerebrum

• involuntary muscles and cerebellum

• interneurons and spinal cord

• smooth muscles and medulla

In the human central nervous system, the brain stem directly controls

• involuntary activity

• memory

• voluntary activity

• balance
