This is something that all living organisms do. It can be either sexual or asexual.

What is reproduction?

100

An experiment in which only one variable is changed or altered,

What is a controlled experiment?

100

This is the amount of energy needed to raise a substance's temperature by making its molecules move faster.

What is heat capacity?

100

This is the bond that formed through the unequal distribution of electrons between two or more water molecules. A bond is formed between the partial negative side of one atom and the partial positive side of another atom.

What is a hydrogen bond?

100

This is the amount of energy needed to get a reaction started.

What is activation energy?

200

This is the molecular coding that is the basis for all living organisms.

What is a universal genetic code (DNA)?

200

This is the variable that is observed and changes in response to the independent variable. It is the variable that is measured.

What is the dependent variable?

200

This would be the word that you would use to describe water's placement on the pH scale.

What is neutrality?

200

This bond refers to the complete transfer of electrons from one atom to another atom. This bond typically produces positive and negative ions.

What are ionic bonds?

200

The elements or compounds that engage in a chemical reaction.

What are reactants?

300

This the characteristic in which organisms respond to either external or internal stimuli in order to live and survive.

What is responding to the environment?

300

A tentative explanation that can be tested further through experimentation or observation

What is a hypothesis?

300

This is the property of water that allows it to dissolve both ionic compounds and polar molecules, making it a good solvent in many solutions.

What is polarity?

300

This type of bonding refers to the sharing of electrons between 2 atoms.

What are covalent bonds?

300

The elements or compounds produced by a chemical reaction.

What are products?
400

All living organisms are composed of one or more of these units which are the basic units of structure and function in living organisms.

What is composed of cells?

400

This is the variable that is deliberately changed in a controlled experiment

What is the independent variable?

400

These are the types of bonds that occur in a glass of water.

What are covalent and hydrogen bonds?

400

This is a substance formed by the chemical combination of two or more elements in definite proportions.

What is a chemical compound?

400

These are biological catalysts and proteins that lower the activation energy of a reaction. They can either put two reactants together or break them apart.

What are enzymes?

500

This is the stable internal balance that all living organisms maintain.

What is homeostasis?

500

A logical interpretation based on what scientists already know

What is an inference?

500

These are the two properties of water that are involved in transporting water from the roots of a plant to its stem and leaves.

What is cohesion and adhesion?

500

These are bonds that form between all atoms/molecules based on electron shifting. These are very weak and fluid bonds.

What are Van der Waals forces?

500

This is the term used to describe the temperature at which enzymes function best. If the enzymes are in temperature conditions higher than this, then they will be denatured.

What is optimal temperature?
