What goes into photosynthesis?

Carbon dixodie + Water = Oxygen + Glucose

What goes into Cellular Respiration?

Oxygen + Glucose = Carbon Dixoide + Water + ATP

Whats the coefficient infront of each component?

What can be turned into eachother?

What is an adaptation?

A characteristic or behavior that helps an organism survive and reproduce in an environment

Example of adaptation:

Kangaroos: pouches to carry offsprinf

Example of adaptation:

Spider: makes webs to catch prey

Example of adaptation:

Example of adaptation:

Cheetahs, speed

Hypothesis 1:

Aristotle believed that all plants and animals were the same before on earth and the same now

Hypothesis 2:

Life changed overtime, Lamarck, Darwin

What is Lamarcks theory?

Law of use and disuse, use it = more efficient

Dont use it = becomes less and less efficient

What is it called when something is passed onto offspring?

Inheritance of acquired characteristics:

More developed or undeveloped traits are passed onto offspring

What experiment disproved lamarcks theory and who?

August Weismann cut off tails of 20 generations of rats and nothing happened

What is Darwins theory?

That evolution happens due to natural selection

What is natural selection?

Its a phenomenon occurring in the natural world where organisms have traits that are suited to the environment and have a higher chance to live
