A
  • prokaryotes
  • single celled
  • microscopic
  • live in extreme environments
23
Q

25
What are Animilia?
- multicelled - eukaryotic - eat their own food
26
What are Fungi?
- eukaryotes - multi celled - dissolve nutrients for food
27
What is evolution?
The theory that all life evolved from a single ancestor, however over time adapted certain characteristics which made them more suitable for survival
28
What is natural selection?
The theory that species that were best created for survival reproduce and give their children the same characteristics, over time certain traits are passed down
