|
|
|
What is the difference between Exo? and Endo?

|
|
What is the Monomer, Structure, Function of a Carbohydrate, Lipid, Protein, and Nucleic acid? How do we get it?
|
Carb-Monosacharides, Ring structure, energy source, Breads and Pastas

|
|
What is meant by activation energy?
|
Energy needed to activate a chemical reaction.
|
|
|
How does an Enzyme work?
|
enzymes are catalysts for chemical reactions in living things. Enzymes, like other catalysts,lower the activation energy and increase the rate of chemical reactions.
|
|
|
Substances that change during a chemical reactions are known as...
|
Reactants
|
|
|
What decreases the amount of activation needed by a chemical reaction?
|
Enzymes/ Catalysts
|
|
|
What are three things thag affect thebfinction of the Enzyme?
|
Temperature,Structure, PH
|
|
|
what is the basic unit of life
|
Cell
|
|
|
what is the basic unit of matter?
|
Atoms
|
|
|
when does a trait become known as an adaptation?
|
It is passed through generations and is helful
|
|
|
How is evolution important to life on earth?
|
If you dont evolve you would die.
|
|
|
What is a substrate?
|
the substance attached to the enzyme
|
|
|
where does the energy for most Earth's organisms begin?
|
The Sun
|
|
|
what is a polar molecule?
|
Molecules that consist of Atoms, Protons, and Electrons
|
|
|
what property of water allowed it to travel up the filter paper in the lab?
|
Adhesian
|
|
|
when do cells of livig organisms have to work together?
|
All the time
|
|
|
individuals can only produce when they are?
|
living
|
|
|
describe in details what is a sollution? how do they realte to eachother.
|
Solutes is being what is dissovled and solvents is being what contains the solute. Solute is always the substance that is dissolved, and the solvent is the liquid in which solute dissolves.
|
|
|
Tell how water and what property of water allows it to move up in a plant organism?
|
Adhesian it allows the water to curve upward allowing plants to transport water from their roots to their leaves
|
|
what is the animal able to do what is being shown here?
|
The hydrogen bonds which creat surface tension.
|
|
|
How does a compund differ from an Element?
|
Elements cannot be broken down. Compunds are two or more elements combined.
|
|
|
During a chemical reaction what substances are being changed?
|
The Reactants
|
|
|
How do different substances form during a chemical reaction?
|
attach cells to enzymes
|
|
|
what reduces the activation energy needed to start a chemical reaction?
|
Catalyst
|
|
|
why is it important to know Biology?
|
Biology can tell us the physical make up of our bodies which allows up to invent cures and treatments for many diseases.
|
|
|
which cannot be broken by normal chemical means, a compund or element?
|
Element
|
|
|
how does adhesian differ from cohesian?
|
adhesian- the attraction among molecules of a different substance, cohesian- the attraction among milecules of a substance.
|
|
|
when given a chemical equation what side is reactants and what side is products?
|
reactants-left
Products- right |
