Evolution
a change or the process of change by which an organism or species becomes better suited to its environment.
What is an adaptation?
Water sticks to water
What is cohesion?
Macromolecule made of amino acids
What is a protein?
this biogeochemical cycle elements is not found in a gaseous state
What is phosphorus?
High temperatures and pH changes can cause this to denature
What is an enzyme?
This is a change of the sequence of DNA sequence that can be positive, negative or have no change for survival
What is a (genetic) mutation?
What sticks to a substance other than water
What is adhesion?
DNA and RNA are composed of subunits called:
What are nucleotides ?
This organism transfers carbon from the atmosphere and creates carbohyrates (glucose) in the biosphere
What are plants?
This macromolecule gives quick bursts of energy
What is a carbohydrate ?
The formation of a new and distinct species in the course of evolution
What is speciation?
This property of water allows the top of a lake to be frozen first
What is "ice floats" or "water is less dense in solid form" ?
These two macromolecules are both a source of energy
What are carbohydrates and lipids?
Two ways water can change from liquid to gas, and enter into the atmosphere
What is evaporation and transpiration?
Body parts that share a common function but not a common structure
(ex: Bat/ butterfly/bird wings)
What is an analogous structure?
This adaptation can be a benefit that reduces the risk of being eaten by a predator because you BLEND with your surroundings
What is camouflage?
True or false: Water has a high heat capacity?
What is "true" ?
Elements that are found in all 4 macromolecules
What are C,H, O (carbon, hydrogen and oxygen) ?
The amount of energy that is transferred from one trophic level to the next
What is 10% ?
This macromolecule is best for learning in school, because it does not cause spike blood sugar or cause heart disease
What is a protein?
Sharing similar bone structures in forelimbs with other different species shows evidence of descent from a ...
What is a common ancestor?
This bond is formed between the positive hydrogen atom in one molecule and a small negative atom of the same or a different polar substance.
Responsible for water's unique solvent capabilities.
What is a hydrogen bond?
Proteins are made of these elements
What are carbon, hydrogen, oxygen and nitrogen (CHON) ?
This type of bacteria changes atmospheric nitrogen into ammonium in the nitrogen cycle
What is nitrogen fixing bacteria?
the process where organisms better adapted to their environment tend to survive and produce more offspring.
What is natural selection?
