The Asian shore crab invaded parts of the eastern coast of the United States about 15 years ago. The Asian shore crab preys on blue mussels. In the time since the Asian shore crab arrived, the average shell thickness of the blue mussel population has increased.
Which of the following is the most likely reason that this increase in shell thickness has occurred?
Blue mussels with thick shells attract more crabs that mussels without thick shells.
Blue mussels with thick shells grow in larger colonies than mussels without thick shells.
Blue mussels with thick shells catch more food per day than mussels without thick shells.
Blue mussels with thick shells survive and reproduce more successfully than mussels without thick shells.

C
D
The diagram shows interactions between food chains in an ecosystem in the African savannah. Which arrows indicate the flow of chemical energy?
I and II only
I and III only

I, II and III
The Australian pitcher plant (Cephalotus follicularis) is a green plant that traps and feeds on flies and other live insects. What is this plant’s mode of nutrition?
Producer and saprotroph
Autotroph and detritivore
Autotroph and heterotroph
Consumer and saprotroph
Which characteristic of water in a gas phase (water vapour) classifies it as a greenhouse gas?
It absorbs and then re-emits some of the long wave radiation emitted by the Earth’s surface.
It prevents short wave radiation from reaching the Earth’s surface.
It absorbs UV radiation but does not re-emit it.
It absorbs infra-red radiation but does not re-emit it.
A water strider can skate along the top of a pond because:
covalent bonds result in water cohesion
hydrogen bonds result in water cohesion
water striders have adapted their behaviour to survive in this environment.
low surface tension of water
Ice floats on water because
adhesion
cohesion
water expands when it freezes
water contracts when it freezes

Earth revolves around the Sun, and the Moon revolves around Earth. The Moon’s orbital path is sometimes above and sometimes below the plane of Earth’s orbit, as shown in the diagram below.
What would happen if Earth’s orbit and the Moon’s orbit were in the same plane?
Eclipses would occur every month.
The Moon would not have phases.
All sides of the Moon would be visible from Earth.
The same side of the Moon would always face the Sun.
Why does the moon look red in this image.
It is a total lunar eclipse. Only long wavelengths of sunlight pass through the Earth's atmosphere to reach the moon.
It is a total lunar eclipse. Only short wavelengths of sunlight pass through the Earth's atmosphere to reach the moon.
It is a total lunar eclipse. The reduced light levels from the Earth blocking the sunlight allows us to see it contains iron oxide (rust).
It is a total lunar eclipse. The moon gets cooler without the direct sunlight and doesn't emit as much light towards Earth.
