What is regulation (homeostasis)?
This property of life allows organisms to maintain stable internal conditions despite changes in the external environment.
What is an atom?
The smallest unit of matter that still retains the properties of an element.
What are the 4 types of macromolecules?
Carbohydrates, lipids, proteins, and nucleic acids
This type of biological molecule contains carbon, hydrogen, and oxygen in about a 1:2:1 ratio and is commonly used for short-term energy storage. What is this?
Is amino an acid or base?
What is reductionism?
The process by which organisms better suited to their environment survive and reproduce more successfully than others.
What are valence electrons?
Electrons found in the outermost electron shell that largely determine an atom's chemical behavior.
What macromolecule class doesn’t not a polymer?
Lipids
What are hydrophilic and hydrophobic molecules?
Although both are composed primarily of carbon and hydrogen, one class of molecules dissolves readily in water while the other does not because of differences in polarity.
What does hydroxyl do to a molecule in water?
It make it dissolve in water.
What is gene expression?
The process through which information stored in DNA is used to produce a functional cellular product, such as a protein.
What is a covalent bond?
A bond formed when two atoms share one or more pairs of electrons.
What is hydrolysis?
Hydrolysis splits a polymer by adding water back to the polymer.
What are isotopes?
Two atoms of the same element that differ in the number of neutrons they contain.

What is a hypothesis?
A scientific explanation based on observations that leads to predictions that can be tested through experiments or further observations.
What is electronegativity?
An atom's attraction for electrons in a chemical bond.
What is dehydration synthesis?
It is when is joins monomers and releases water.
What is a hydrogen bond?
The attraction between a partially positive hydrogen atom and another electronegative atom, often oxygen or nitrogen.
What are 7 functional groups?
Hydroxyl, carbonyl, carboxyl, amino, sulfhydryl, phosphate, and methyl
What are emergent properties?
New characteristics that arise from the arrangement and interaction of parts within a complex system and are not found in the individual parts alone.
What is chemical equilibrium?
The condition in which the forward and reverse reactions of a chemical process occur at the same rate.
Draw C4H10 the two different ways you can
Structural isomers and Carbon skeleton
What is gene expression?
The process through which information stored in DNA is used to produce a functional cellular product, such as a protein.
