  • Question 1

An organism's scientific name has two Latin words (genus and species). This is called the ____________ system.

CORRECT ANSWER
binomial
EDDIE SAYS
An organism's scientific name has two Latin words (genus and species). This is called the binomial system.
  • Question 2

A symptom of a specific genetic disorder is difficulty in breathing as the lungs are clogged with thick mucus. This also leads to infections. What genetic disorder is this?

CORRECT ANSWER
cystic fibrosis
EDDIE SAYS
People with cystic fibrosis have difficulty in breathing as their lungs are clogged with thick mucus. This also leads to infections.
  • Question 3

In a precipitation reaction a soluble product forms a precipitate.

CORRECT ANSWER
false
EDDIE SAYS
The statement is false; in a precipitation reaction an insoluble product forms a precipitate.
  • Question 4

What does it mean being carbon neutral?

CORRECT ANSWER
It means not adding carbon dioxide to the atmosphere.
EDDIE SAYS
Being carbon neutral means not adding carbon dioxide to the atmosphere.
  • Question 5

Ancient astronomers could see patches of fuzzy light that they called __________.

CORRECT ANSWER
nebulae
EDDIE SAYS
Ancient astronomers could see patches of fuzzy light that they called nebulae.
  • Question 6

Calculate the power of an appliance if the current is 2A and the voltage 9V.

CORRECT ANSWER
18W
EDDIE SAYS
power = current x voltage = 2 x 9 = 18 W
  • Question 7

Calculate the payback time of an energy saving item if the cost is £60.00 and the saving per year £15.00.

CORRECT ANSWER
4 years
EDDIE SAYS
payback time = cost/savings per year = 60/15 = 4 years
  • Question 8

force = change in momentum/time = 20/5 = 4 N
  • Question 14

How much work does a person do when she lifts a 100 N box from the floor to a shelf at 2 m height?

CORRECT ANSWER
200 J
EDDIE SAYS
work done = force x distance moved = 100 x 2 = 200 N
