only in your backyard.

2. Why do we need biodiversity?
a) it provides us with the food we need to eat
b)it provides us with virtually all the things we need to stay alive
c)so we have plenty of trees to use for fuels and materials

3.which of the following places has the highest biodiversity?

5. in these ‘hotspots’ how much of the worlds species are found there?
a)10%
b)25%
c)50%


6. what does ‘endemic’ mean?

b) when something is only found in one place
c) when a disease spreads throughout the world

7. why is biodiversity under threat?
a) habitat destruction

b. the both involve ATP
c. the they both involve chemiosmosis
d. all of the above

How do the nutrients necessary for plant growth get into the soil?
O The soil absorbs sunlight.
Water filters through the soil.
Organic matter is decayed in the soil.
The soil is exposed to air.

This diagram represents the cell cycle. When cells leave the cell cycle, they exit during G1 phase and then enter G0 phase, a resting period. Most normal cells can leave G0 phase and reenter the cell cycle at G1 phase before entering S phase. Cancer cells are different because they cannot enter G0 phase and are likely to do which of the following?
A Fail to complete S phase
B Continuous unregulated cell division
C Mutate during G phase
D Die after completing mitosis
