Dr Dabour Hub Science Diagram and Course Material
All three flasks were respiring, but at different speeds
The glass beads prove that beans need light to respire
The boiled beans respired faster because they were hotter
Only the germinating beans were respiring; the boiled beans were dead

Yeast gives off the most gas when it has no food
12.
Lina's parents measured her height on her birthday each year. Which reading is most likely to be a measuring mistake, and why?

Age 6, because it is the smallest value in the table
Age 9, because growth is permanent so height should not fall
Age 7, because the rise from age 6 is exactly 6 cm
13.
Four students each described an observation and named the characteristic of living organisms it shows. Which student is correct?
Joe, as urine carries waste made in cells
Sam, as panting is the same as respiration
Nia, as eating food is the same as growth
Ivy, as faeces are waste made by the body cells
14.
The table shows four substances that leave living organisms. Which of them are examples of excretion?
All four of the substances
Faeces only, as it is solid waste
Carbon dioxide, urea and oxygen
Carbon dioxide and faeces only
15.
Priya says a cloud is alive because it moves across the sky and gets bigger. Which is the best evaluation of her idea?
She is wrong: the wind carries it, and it has no cells and cannot reproduce
She is right, because it shows movement and growth
She is right, because water in it came from living things
She is wrong only because a cloud does not eat food
16.
A cactus grows in dry desert sand and is never fed by anyone. How does it carry out nutrition?
It does not need nutrition while it is in sand
It makes its own food by photosynthesis
It takes in ready-made food through its spines
It gets all its food by respiration in its roots
17.
Why do biologists NOT use "breathing" or "having a heartbeat" as the test for whether something is alive?
Breathing and heartbeats are too hard to measure
Only humans breathe and have a heartbeat
Breathing is the same as respiration, so it is counted twice
Plants are alive but have no heart and do not breathe
18.
An eagle high in the sky spots a mouse on the ground and dives down to catch it. Which characteristics does the eagle show, in the order they happen?
Movement, then excretion
Growth, then sensitivity
Sensitivity, then movement

A balloon getting bigger as air is blown into it
A dried raisin swelling up when soaked in water
20.
Why is reproduction essential for a kind of organism, such as the Arabian oryx, to keep existing?
Without young, the kind would die out when the adults die
Reproduction gives each adult the energy it needs
Reproduction removes waste made inside the body
Without young, adults would stop growing bigger
21.
Farida wants to show that garden snails are sensitive to touch. Which plan is best?
Weigh one snail every day for a week and record its mass
