○ What are characteristics of the three Domains?
Give this one a try later!
Archaea: Singular, archaeon. Group of prokary-otes that are more closely
related to eukaryotes than to bacteria.
Bacteria: Singular, bacterium. The largest, most diverse and well-known
group of prokaryotes
Eukarya: Organisms whose cells characteristically have a nucleus (protists,
fungi, plants, and animals).
○ What is the fluid mosaic model of cell membrane? How do phospholipids
contribute to this model?
Give this one a try later!
, -A cell membrane can be considered a two-dimensional fluid of mixed
composition.
○ What makes H2O a polar molecule?
Give this one a try later!
unequal charge distribution over the atoms of hydrogen and oxygen
involved in the molecule of water.
○ What makes an atom an isotope?
Give this one a try later!
atoms of same element that differ in number of neutrons
i. What bonds are found between the amino acids within a polypeptide?
Give this one a try later!
The covalent bond that links amino acids in a chain
■ What is osmosis? What determines the movement of the water across the cell
membrane?
Give this one a try later!
, osmosis: Diffusion of water through a selectively permeable membrane.
i. What are some monosaccharide and polysaccharide examples?
Give this one a try later!
•The simplest carbohydrates are sugars.
−Monosaccharides or disaccharides
•Complex carbohydrates are combinations of simple sugars -
polysaccharides
○ What type of bonding occurs from oppositely charged atoms (ions)? What type of
bonding occurs when the atoms share electrons? Why would an atom give, receive or
share electrons?
Give this one a try later!
ionic bonds
taxonomy
Give this one a try later!
practice of naming and classifying species; developed by Linnaeus
-Species: organisms which share the same characteristics and are capable
of exchanging genes/producing offspring
-Genus: a group of species that share a set of unique traits
•Every species is given a unique two-part scientific name consisting of its
genus and species. (Example: Humans are Homo sapiens.)
