Goals of science
Nature can be understood through
Systematic study
Observation- using your
5 senses
Carbohydrates are sugars or starches used to store
Energy
Lipids are fats or
oil
Changes in nucleotides are called
polynucleotides
Scientific ideas are open to
Revision
Qustion- must be
testable
They are built of smaller pieces called
Monosaccharides
Functions: storing
energy for later use and other roles
DNA
( deoxyribonucleic acid ) double helix, genetic materials
Sound scientific ideas withstand the test of
Time
Hypothesis- a possible
answer that can be tested
Fructose: found in
fruit
Lipids are made of chains of
fatty acids
RNA
( ribonucleic acid ) single side, helps make proteins
Science
Cannot provide answers to all questions
Expermint- a
systematic investigation
glucose: broken down from larger
molecules
found in
plants
Nucleic acids contain
Sugar, phosphate, nitrogen base
Analysis- examining the
Data
Polysaccharides are chains of
multiple sugars
Phospholipids: the major components of the cell
membranes
