Termed as an organized way of gathering and analyzing evidence about the natural world
science
smallest units considered to be alive
cells
Termed as the basic unit of matter
atom
Monomers join together to form
polymers
Made up of three subatomic particles
atom
Termed as a logical interpretation based on what scientists already know, previous experience
inference
Living things maintain a relatively stable internal environment, a process known as
homeostasis
A negatively charged subatomic particle in atoms
electron(s)
An attraction between molecules of the same substance
cohesion
An attraction between molecules of differnet substances
adhesion
In a controlled experiment, how many variables are changed at a time?
one
Living things are based on a universal genetic code written in a molecule called
DNA
Atoms of the same element that differ in the number of neutrons are called
isotopes
A mixture in which all the components are evenly spread out
solution
Starches and sugars are examples of this group of organic compounds
carbohydrates
Termed as a well-tested and highly reliable explanation that unifies a broad range of observations and hypotheses
theory
Name five characteristics of living things.
Made up of units called cells, ability to reproduce, based on a universal genetic code, ability to grow and develop, ability to obtain and use materials and energy, ability to respond to the environment, ability maintain a stable internal environment, and tendency as a group to change over time
This type of bond is formed when one or more electrons are TRANSFERRED from one atom to another
ionic bond
Proteins are polymers of
amino acids
This type of bond is formed when electrons are SHARED rather than transferred
covalent bond
What does SI currently stand for in terms of standard units?
International System of Units
The combination of chemical reactions through which an organism builds up or breaks down materials is called
metabolism
Strong forced bind protons (positively charged) and neutrons (no charge) together in the
nucleus
A mixture of water and undissolved materials
suspension
Any compound that forms hydrogen ions in solution
acid
