Question 1
Using the table, which kind of message pulls your hand off a hot pan?
Two ways the body sends messages Feature Nerve signals Hormones Travel through nerves the blood Speed a fraction of a second seconds to hours Effect lasts a short time minutes to years - nerve signals
- hormones
- both, at exactly the same speed
nerve signals
Hint: You need to move in a fraction of a second. Check the Speed row.
Question 2
Which part of the eye focuses light?
- the lens
- the cornea only
- the pupil
- the eyelid
the lens
Hint: The lens bends light onto the retina.
Question 3
The jelly-like fluid inside a cell is the…
- wall
- cytoplasm
- nucleus
- membrane
cytoplasm
Hint: Organelles float in it.
Question 4
Temperature measures the average…
- size of particles
- weight of a substance
- motion energy of particles
- color of a substance
motion energy of particles
Hint: Faster particles, higher temperature.
Question 5
Why should a test be repeated several times?
- To waste time
- Because one is never enough fun
- To change the answer
- To make sure results are reliable
To make sure results are reliable
Hint: Repeat for confidence.
Question 6
An LED bulb is more efficient than an incandescent bulb because it…
- is made of glass
- uses no electricity
- produces more heat
- turns more of the electrical energy into light
turns more of the electrical energy into light
Hint: An incandescent bulb gives off most of its energy as heat.
Question 7
Which organ stores urine until you go to the washroom?
- the bladder
- the kidney
- the ureter
- the stomach
the bladder
Hint: This stretchy organ fills up like a balloon and then empties.
Question 8
Which of these is one of the basic tastes?
- cold
- spicy
- bitter
- crunchy
bitter
Hint: Spicy and crunchy are felt, not tasted.
Question 9
Which part releases energy from food?
- Vacuole
- Nucleus
- Mitochondria
- Cell wall
Mitochondria
Hint: The cell's power stations.
Question 10
A metal spoon feels colder than a wooden spoon at the same temperature because metal…
- makes cold
- is actually colder
- is wet
- conducts heat away from your hand faster
conducts heat away from your hand faster
Hint: Feeling cold is heat leaving.
