1
Heterotroph
organisms that depend on other organisms for food
2
Mutation
An abrupt and marked change in the DNA of an organism compared to that of its parents
3
Theory
A hypothesis that has been thoroughly tested and has data to back it up
4
Photosynthesis
the process by which green plants and some other organisms use the energy of sunlight and simple chemicals to produce their own food
5
Homeostasis
The maintenance of stable internal conditions.
6
Inference
Logical interpretation based on prior knowledge experience or evidence
7
Anabolism
The sum total of all processes in an organism that use energy and simple chemicals and structures necessary for life
8
Organisms that make their own energy are called:
Heterotrophs
9
Explain why it can be said that most of life on Earth gets its energy from the sun.
Autotrophs energy directly from the sun. Whereas heterotrophs do not get their energy directly from the sun they either eat autotroph‘s or other heterotrophs that eat autotrophs

11
What is a hypothesis?

13
A tiger develops lockjaw and can no longer open its mouth. Which of the criteria for life will it not be able to perform?
Since the tiger cannot open its mouth he cannot eat therefore metabolism and energy will Be affected and if you cannot eat he cannot gain energy and if he cannot get energy he cannot live.
14
Why did the law of spontaneous generation survive for so many years?
It survived because experiments which were later found to be flawed seemed to confirm it.
