Intro to Biology
What is life?
reproduction, growth and development, energy processing, response to stimuli
Covalent: form between that share electrons
Hydrogen: a weak type of bond that forms between a hydrogen covalently bond to a electronegative molecule
Define: monosaccharide, disaccharides, polysaccharide
Monosaccharide: one sugar unit
Disaccharide: two sugar units
Polysaccharide: multiple sugar units
What is Biological Evolution?
Common set of characteristics, shared evolutionary history
monomers: amino acids
polymers: peptides
archaea, and bacteria (prokaryotic cells)
List the taxonomy order
Domain, kingdom, phylum, class, order, family, genus, species
What is the difference between cations and anions
cations: ions that are positively charged
anions: ions that are negatively charged
monomers and polymers for nucleic acids
Monomers: nucleotides
Polymers: DNA, RNA
The atomic mass means...
what is taxonomy?
the grouping of species based on common ancestry
Why is water essential to Life?
Water has many properties:
Cohesion, adhesion, a high boiling point, capillary action, and more.
monomer and polymer for lipids
Monomer: glycerol and fatty acids
Polymer: triglycerides, phospholipids, membrane lipids
define covalent bonds the two types of covalent bonds
A bond between atoms that can share electrons.
Polar: different electronegativity
Nonpolar: same electronegativity
protista, plantae, fungi, and animalia
Acids and bases ionizes which ions?
Bases: ionizes hydroxide ions (OH-)
How are polymers broken down to monomers? And how are monomers built into polymers?
Breakdown: hydrolysis
Linked together: dehydration reaction
What are buffers?
a substance that maintains pH balance
