Answers
1
What is the difference between velocity and speed?
Velocity shows a direction
Velocity considers forces
Speed is distance / time
Velocity applies to cars only
2
What is the word formula for respiration?
Oxygen → Carbon dioxide + water
Water + Glucose → Carbon dioxide + water
Carbon dioxide + water → Glucose + oxygen
Oxygen + glucose → Carbon dioxide + water
3
The movement of water seen in this picture is called
Diffusion
Osmosis
Active transport
4
Bob has finally got the box moving at a
constant, steady speed
. What is the value of friction?
Exactly 50N
<50N
> 50N
There isn't enough information to tell
5
Physics can explain the shape of the fireworks because...
Chemistry uses different elements to make colourful shapes
Forces act in 1 direction
Every force has an equal and opposite force
Physics allows us to make rockets
6
Diffusion is important in leaves because...
It prevents insects from eating the leaf
It allows carbon dioxide to enter through the stomata
It allows carbon dioxide to leave the stomata
It allows oxygen to leave the stomata
7
This pen appears to levitate. It is showing an example of...
Action-at-a-distance
Unequal forces
Contact forces
Magnetic attraction
8
What charge does a chlorine ion have?
-1
-7
+7
+1
9
What is the balanced symbol equation for photosynthesis?
6C6H12O6 + 6O2 → 6H2O + 6CO2
6CO2 + 6H2O → C6H12O6 + 6O2
6CO2 + 6H2O → 6C6H12O6 + 6O2
C6H12O6 + O2 → H2O + CO2
10
What ions are present in table salt?
Na+ and Cl-
Na- and Cl+
Cl- and K+
Cl- and K+
11
How does the lock and key model explain the action of enzymes?
Substrates join to enzymes and unlock them
Enzymes are specific chemicals that lock all molecules up
Enzymes have a specific shape that fits a specific substrate
Enzymes have a specific shape to fit all substrates
12
How is active transport different to diffusion and osmosis?
It can move molecules from a low to a high concentration
It does not require energy
It requires energy
It can move molecules from a high to a low concentration
13

Bromine
Sodium
Iodine
Chlorine
14
What force do the jagged lines represent?
Gravity
Upthrust
Weight
Friction
15
Flame spectroscopy was carried out on 2 mystery powders. What can you deduce about the powders?
They contain different elements
Nothing
They contain the same elements
16
Bob has managed to exert a greater force now! What is the
resultant force
?
← 65N
→ 80N
→15N
← 145N
17
What is the balanced equation for this reaction?
2Na + Cl2 → 2NaCl
Na2 + Cl2 → NaCl2
Na + Cl2 → 2NaCl
Na + Cl → NaCl
18
Describe this journey
The object went at many different speeds
The object was stationary (still) at 1 second
The object travelled a total of 10m
The object moved for 2 seconds at a constant speed
19
This rocket is accelerating. What can you conclude about the forces acting on the rocket?
The upwards and downwards forces are equal
There are no longer any forces acting on the rocket
The forces acting up are greater than the downwards force
The forces acting down are greater than the upwards force

Choose 1
Mushroom
Yeast
Lungless-frog
Apple tree
27
The random movement of particles from a high concentration to a low concentration is called...
Active transport
Osmosis
Diffusion
28
What are enzymes?
Scissors found in the cell
A biological organism that eats food
Synthetic chemicals that make chemical reactions happen
A protein that speeds up chemical reactions in cells
29
What molecule(s) can be moved into a cell by active transport?
Nitrates
Sugar
Water
Oxygen
30
Why is NaCl found in cube shaped crystals?
People prefer salt to be served as cubes
Cubes have a large surface area so are good for cooking
The ions are arranged in a regular lattice structure
This bonds between different sodium ions make this shape
