100
The variable that scientists intentionally change in an experiment
Independent Variable
100
True or false: in order for something to be living they need to display all 8 characteristics of life
True
100
The property of water where water "sticks" to water
cohesion
100
What is the monomer of proteins
amino acids
100
Enzymes are what type of macromolecule
Proteins
200
The variable that scientists collect data from
The dependent variable
200
What characteristic of life is displayed by a human eating an apple
obtain and use energy
200
Water is called this because it can dissolve many substances, like salt or sugar.
Universal solvent
200
These macromolecules, responsible for the genetic code, are composed of nucleotide monomers.
Nucleic acids
200
What do enzymes do
act as biological catalysts (speed up chemical reactions)
300
Something that is heavily researched and describes HOW something occurs
theory
300
What characteristic of life is displayed by a plant growing towards sunlight
Respond to stimulus
300
This property of water allows it to stick to other surfaces, helping it move up plant roots.
Adhesion (capillary action is better)
300
What is the monomer and polymer of carbohydrates
monomer- monosaccharide
polymer- polysaccharide
300
substrate
400
What is the purpose of a control group
To get no change in IV to serve as a standard of comparison
400
What characteristic describes that Humans regulate their body temperature through sweating or shivering, maintaining a stable internal environment despite external temperature changes.
Maintains Homeostasis
400
Because of this property, ice floats on water, allowing fish to survive in cold lakes.
Ice is less dense as a solid than a liquid
400
This polymer of lipids makes up the cell membrane
phospholipids
400
Name at least two factors that influence enzyme activity
pH and temperature
500
In an experiment that is trying to measure the effects of stimulants (ex. caffeine) on rat brain development, the control group would be what?
The rats that don't get treated with any caffeine
500
What characteristic is displayed by Bacteria undergo binary fission, a process where one cell divides into two genetically identical daughter cells.
Reproduction
500
This property of water helps regulate body temperature, as water heats up and cools down more slowly than air.
High specific heat
500
These polymers of lipids, made of glycerol and three fatty acids, are used by the body for long-term energy storage.
Triglycerides
500
This term describes when a protein (enzyme) loses it shape and can no longer function due to extreme heat or pH changes
Denaturation (Denatured)
