Chlorophyll reflects that light
Chlorophyll soaks up red and blue light for energy and bounces the green back to your eyes.

The nucleus
Robert Hooke named cells in 1665 because the tiny boxes in cork reminded him of monks' rooms in a monastery.

A cell wall and chloroplasts
The wall is made largely of cellulose and the chloroplasts hold the chlorophyll for photosynthesis.
Q 14Earth's inner core is a solid ball made mostly of iron and which other metal?
Nickel
The outer core around it is liquid, and its churning creates Earth's magnetic field.
Q 15Which scientist proposed the idea of continental drift in 1912?

The Ring of Fire
Earth's lithosphere is broken into seven or eight major plates plus many smaller ones.
Q 17In the water cycle, what is the name for water vapour turning back into liquid droplets to form clouds?
Condensation
About 97% of Earth's water sits in the oceans, and the Sun's energy drives the whole cycle.

Igneous
Granite cools slowly underground while basalt forms from lava at the surface; sedimentary rocks are the ones that hold fossils.

Limestone
Slate is made the same way from shale; the endless changing of one rock type into another is called the rock cycle.

Carbon dioxide
Combined with water and sunlight it makes sugar, and oxygen is released as the leftover.
Q 24In a food chain, what are the plants and algae at the very bottom called?
Producers
Only about ten percent of the energy at one level passes to the next, which is why food chains rarely go beyond five levels.

Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
The four inner planets are rocky, the four outer ones are giants, and the asteroid belt lies between Mars and Jupiter.

About 99.9%
Jupiter and Saturn together make up more than 90% of what is left over.
Q 27Using the order of operations, what is 1 - 2 x 3^4?
-161
Exponents come first (3^4 = 81), then multiplication (2 x 81 = 162), then subtraction; PEMDAS is the usual memory aid.
Q 28In the mnemonic PEMDAS, what does the P stand for?
Parentheses
Multiplication and division share the same rank and are worked left to right, as are addition and subtraction.
Q 29Which of these numbers is prime?
29
A prime has no factors except 1 and itself; 1 is not counted as prime, and Euclid proved there are infinitely many primes.
