Branch of science is concerned with the chemical processes that occur in living things

• biochemistry
• homeostasis
• scientific model

Stable internal conditions of a living thing

• biochemistry
• homeostasis
• scientific model

Chemical bonds result from the sharing of electrons in the outer atomic orbital

• adhesions
• covalent bonds
• ionic bonds

Weight of a substance for a specific volume or the number of organisms in an area?

• activation energy
• biochemistry
• density

Occurs when molecules have an uneven distribution of charges

• acid
• polarity
• specific heat

The measure of the heat energy required to increase the temperature  of a unit quantity of a substance by a certain temperature interval

• activation energy
• density
• specific heat

The scale that measures acidity or alkalinity (basicity) of a solution scaling from 1 to 14, with the neutral midpoint being 7

• biochemistry
• denature
• pH

A polymer with a high molecular mass. Within organisms there are  four main groups: carbohydrates, lipids, proteins, and nucleic acids

• macromolecule

• proton

• catalyst

Speeds up a chemical reaction

• atom
• catalyst
• nucleic acid

Reaction that absorbs energy (heat)

• covalent bonding
• endergonic (endothermic) reactions
• exergonic (exothermic) reactions
