  • Question 1

Describe the main characteristics of the Animalia Kingdom. It includes organisms like humans, birds and snakes.

CORRECT ANSWER
EDDIE SAYS
You will get 1 mark for each of the following statements:
- multicellular organisms
- heterotrophic feeders so no chlorophyll
- no cell wall
- complex cell structure with nucleus
  • Question 2

Name the other four Kingdoms of organisms.

CORRECT ANSWER
EDDIE SAYS
You will get 1 mark for each of the following Kingdoms:
- Plantae (plants)
- Fungi
- Protoctista
- Prokaryotae
  • Question 3

The picture shows HIV particles attacking a cell.

Why is there no kingdom for viruses?

 

CORRECT ANSWER
EDDIE SAYS
You will get 1 mark for the following:
Scientists do not think of viruses as being alive, because they have to use living cells to make copies of themselves (reproduce) and do not show other life processes, such as growth or nutrition.
  • Question 4

Describe the scientific criteria used to decide whether a transplant will go ahead.

CORRECT ANSWER
EDDIE SAYS
You will get 1 mark for each of the following points:
The patient and donor:
- have similar tissues;
- are of similar ages;
- are geographically close;
- and how ill the patient is also plays a part (a healthier patient is more likely to survive the transplant operation than a very ill one).
  • Question 5

What other type of criteria are used to determine whether a transplant will go ahead?

CORRECT ANSWER
EDDIE SAYS
Ethical criteria also play a role when decisions for a transplant are made. Ethical means whether the decision to go ahead with the transplant is morally right.
  • Question 6

What happens in a mutualistic relationship?

CORRECT ANSWER
EDDIE SAYS
In a mutualistic relationship both organisms benefit. However, parasites harm their hosts.
  • Question 7

Describe how tapeworms are adapted to living inside their hosts.

CORRECT ANSWER
EDDIE SAYS
You will get 1 mark for each of the following points:
- Large surface area for food absorption.
- Substances on the surface of its body stop. Digestive enzymes working, so that the worm is not digested.
- Male and female reproductive organs on each body section to self fertilise if other tapeworms are not nearby.
- Hooks and suckers used to attach to the intestine wall.
  • Question 8

Are all alkalis bases? What is the difference between alkalis and bases?

CORRECT ANSWER
EDDIE SAYS
You will get 1 mark for the following points:
All alkalis are bases; they are soluble in water (1 mark), but not all bases can be dissolved in water (1 mark).
  • Question 9

Name a use of antacids after stating what they are.

CORRECT ANSWER
EDDIE SAYS
You will get 1 mark for each of the following points:
- Antacids are medicines.
- They can neutralise excess acid stomach.
  • Question 10

Write the general equation between an acid and a base.

CORRECT ANSWER
EDDIE SAYS
acid + base ---> salt + water
(1 mark)              (1 mark)
  • Question 11

Name three uses of chlorine.

CORRECT ANSWER
EDDIE SAYS
You will get 1 mark for each of the following points:
- kills microorganisms in water supply
- making bleach and other cleaning products
- manufacturing plastics
  • Question 12

What are the potential problems regarding the manufacture and use of chlorine?

CORRECT ANSWER
EDDIE SAYS
You will get 1 mark for each of the following points:
- Chlorine gas may leak from a factory or even a tanker accident.
- Chlorine is toxic and would kill many people if it leaked near a populated area.
  • Question 13

Explain why oxygen and hydrogen are important gases.

CORRECT ANSWER
EDDIE SAYS
You will get 1 mark for each of the following:
Uses of hydrogen:
- rocket fuel
- weather balloons to take measuring instruments into the atmosphere

Uses of oxygen:
- extra oxygen for patients with breathing problems in hospitals
- oxygen for use in nuclear submarines and spacecrafts
  • Question 14

Describe the bromine test and explain its use.

CORRECT ANSWER
EDDIE SAYS
You will get 1 mark for each of the following:
- The bromine test is used to detect double bonds.
- Bromine water is usually orange (although its colour can range from pale yellow to red-brown).
- In the presence of an alkane (saturated hydrocarbon, single carbon atom bond), there is no colour change.
- However, in the presence of an alkene (unsaturated hydrocarbon, double carbon atom bond) a reaction takes place and the colour fades away (decolorises, it becomes a colourless liquid).
  • Question 15

Name the shortest alkane?

CORRECT ANSWER
EDDIE SAYS
The shortest alkane is methane CH4
  • Question 16

Describe the movement of particles in a transverse wave.

CORRECT ANSWER
EDDIE SAYS
You will get 1 mark for the following:
In transverse waves the particles move at right angles (1 mark) to the direction the wave is moving (1 mark).
  • Question 17

In a ____________ wave the particles move back and forth.

 

Complete the sentence using the correct type of wave.

CORRECT ANSWER
EDDIE SAYS
In a longitudinal wave the particles move back and forth, as they are pushed together and spread out.
  • Question 18

Calculate the speed of a wave, if its wavelength is 500 m and 100 Hz. Show your calculation.

CORRECT ANSWER
EDDIE SAYS
You will get 1 mark for the following:
The speed of the wave is calculated using the following formula, where v is the speed, f the frequency and λ the wavelength (1 mark).

v = f x λ = 100 x 500 (1 mark)
= 5 000 m/s (1 mark)
  • Question 19

If the wave in the previous question has a speed of 5 000 m/s, calculate how long it takes it to travel a distance of 100 000 m.

 

CORRECT ANSWER
EDDIE SAYS
          distance  
 wave speed =    ------------------    (1 mark) 
            time  

          distance  
 time =    ------------------    (1 mark) 
       wave speed  

          100 000  
 time =    ------------------    (1 mark) 
            5 000  

time = 20 s (1 mark)
  • Question 20

Describe different ways of reducing energy bills. You can get some ideas from the house diagram.

 

 

CORRECT ANSWER
EDDIE SAYS
Use correct spelling and grammar to gain full marks. Each of the following energy saving ideas can get you 1 mark, but you must put them into a paragraph:
- solar panel for hot water
- loft insulation
- double glazing
- cavity wall insulation
- insulation on hot water tank
- draught proofing
  • Question 21

Describe the energy changes of a bouncing ball from the moment just before it is dropped till it stops moving.

CORRECT ANSWER
EDDIE SAYS
You will get 1 mark for each of the following points:
- Just before it is dropped a bouncing ball has gravitational potential energy.
- While it is falling it has kinetic energy.
- It bounces to a lower height than it is dropped from, because kinetic energy is transferred to thermal energy (1 mark) and lost to the environment (1 mark).
