11 A photograph of a polar bear in its environment is shown below.

One possible reason why polar bears might not be able to survive if the environment they live in changes
is because
(1) the species will experience decreased competition for mates
(2) the new environment will cause greater variation in the species
(3) there will be a larger variety of food sources available
(4) they are adapted to the specific environment in which they now live

(2) Community D modifies the environment, making it suitable for community C.
(3) Community E will develop into community A, if the environment remains stable.
(4) Community A organisms will develop directly into community D organisms.

       by the mitochondria
   (2) decrease in the amount of DNA present in
       the nuclei of cells

15 In the human body, carbon monoxide reduces
   the amount of oxygen that can be transported to
   cells. Breathing in too much carbon monoxide
   will most likely result in the production of

   (2) less glucose            (4) more protein
