This variable in an experiment is often called the "manipulated" variable because it is the variable being tested.
What is the independent variable.
100
In scientific terms the Greek prefix bio means what?
What is life.
100
These three subatomic particles (with charges) are the foundation for every atom on the periodic table.
What is the proton (+), the neutron (+-), and the electron (-).
100
This property of water is what allows water to stick to molecules of different substances.
What is adhesion.
100
This macromolecule is made from an arrangment of Carbon, Hydrogen, Oxygen, and Nitrogen.
What is a protein.
200
The ability to do what with a phenomenon is what separates a theory from a law.
What is explain.
200
This is known as the smallest building block of all things (matter), but is not living.
What is the atom.
200
This subatomic particle is responsible for facilitating ionic and covalent bonds among atoms?
What is the electron.
200
If something is said to be hydrophobic, what does this mean?
It is "water fearing" or isn't attracted to water.
200
Sugars are the monomers for which polymer (macromolecule)?
What is a carbohydrate.
300
A study is conducted on how room temperature affects test scores. Identify the independent and dependent variable in the experiment.
Independent variable- Room Temperature
Dependent variable- Test Scores
300
Sink a putt from 5 feet for these points.
300
This type of bond can be found when Na and Cl join to form a compound?
What is an ionic bond.
300
Because water is polar, non polar molecules will not dissolve in it. This causes a mixture that is not uniform in composition. What type of mixture is this?
What is a heterogeneous mixture or suspension.
300
Identify the type of sugar in the image.
What is a polysaccharide.
400
In a quality experiment the subjects that receive the independent variable is known as this group.
What is the experimental group.
400
These four macromolecules in combination with one another make up all living organisms?
What are carbohydrates, lipids (fats), proteins, and nucleic acids.
400
When a compound is considered to have dipole moment this means the electrons are....
What is not shared evenly.
400
Water molecules can stick to one another because of a property called cohesion. How many other water molecules can one water molecule bond with and explain how.
What is four because each molecule contains 2 partial positive charges (the hydrogens) and 2 partial negative charges (the oxygen), and thus allowing them to become attracted to one another through opposite charges.
400
This structure is the monomer for a nucleic acid?
What is a nucleotide.
500
List all steps of the scientific method in order for these points.
What is (1) Observe, (2) Question, (3) Form a hypothesis, (4) Experiment, (5) Analyze, (6) Iterate, (7) Share.
500
List the hierarchy of life from smallest to largest.
What is the cell, tissues, organs, organ systems, organisms.
500
Identify the two main types of chemical bonding and explain the difference between the two.
What is ionic and covalent. Ionic is between a metal and a nonmetal and the electrons are transferred. Covalent is between 2 nonmetals and the electrons are shared.
500
Draw the dipole moment in a water molecule and explain what property water has because of this electron sharing pattern.
What is a polarity and solubility (dissolves other polar molecules).
500
There are 20 of these that make up all the proteins needed to carry out the many functions of proteins. What are they, and what are two functions of proteins?
What are amino acids and proteins serve as structural support (build muscle tissue), biochemical catalysts, hormones, enzymes, immune support, and much more.
