Question 5

1) Explain Genetic Variation.

Answer 5

The characteristics of individuals within a population vary, due to differences in genes.

Question 6

2) Explain Environmental Change.

Answer 6

Conditions in an area change

eg: Lack of food leads to more competition

Question 7

3) Explain Natural Selection.

Answer 7

By chance, the variations in individuals allow them to cope better, making them more likely to survive (SURVIVAL OF THE FITTEST).

Question 8

4) Explain Inheriatnce.

Answer 8

Survivors breed and pass on variation to their offspring. This makes the next generation with ‘better-adapted’ variations.

Question 9

5) Explain Evolution

Answer 9

If environment remains the same, natural selection will keep occurring over and over again.
A new species evolves with all individuals having the ‘better-adapted’ variations.

Question 10

Explain how stopping taking an anti-biotic early can lead to resistance amongst bacteria.

Answer 10

• Some bacteria rea more resistant than others and take longer to be killed
• When a person stops taking the anti-biotechs, these resistent bacterium stay alive
• These bacterium reproduce and spread, making the resistance more prominent amongst newer bacteria
• Now all of the bacteria are resistant, the anti-biotic will no longer work and won’t treat infections.
