Tendon
connects muscle to bone
Ligament
Connects bone to bone
Joint
Where two bones meet
The nervous system is divided into
Central and peripheral nervous system
The part of the neuron that receives impulses is
Dendrite
The part of the neuron that transmits impulses away from the body
Axon
The specialised junction from which nerve impulses pass from one neuron to the next
Synapse
Hierarchal organizational system for nomenclature
Kingdom

Class
Order
Family
Genus
Species
Properties of water
2 hydrogen bonds covalently bonded to oxygen
Properties of hydrogen bonding
high specific heat
strong cohesive and adhesive properties
water freezes forms a lattice crystal resulting in ice floating in water
polarity of water allows it to act as a universal solvent
Carbohydrates
polymers of sugar; backbone of DNA & RNA
Lipids
fats (saturated & unsaturated), phospholipids, steroids, and waxes
Saturated fat
clogs arteries; no double bonds in their hydrocarbon tail; solid at room temp
Unsaturated fats
double bond in their hydrocarbon tail; liquid at room temp
Phospholipids
lipids w/ a phosphate group
steroids
lipids; precursor to hormones and drugs
Proteins
composed of amino acids, enzymes are proteins that act as catalysts
Fundamental unit of biology
cell
Prokaryotic cells
cell wall & cytoplasm; no defined nucleus (nucleoid)
Eukaryotic cells
nucleus & membrane-bound organelles
Nucleus
container DNA called chromosomes
Ribosomes
organelles that read RNA & translate genetic instructions to produce proteins
Rough ER
protein synthesis and membrane production
Smooth ER
detox and metabolism of molecules
Golgi apparatus
packaging, processing, and shipping
Lysosomes
intracellular digestion
Vacuoles
uptake food through the cell membrane by phagocytosis
eukaryotes have multiple small vacuoles and prokaryotes have one large vacuole
Mitochondria
site of cellular respiration
Chloroplasts
site of photosynthesis
Steps of Aerobic Cellular Respiration
glycolysis, kreb’s cycle, electron chain transport
Steps of Anaerobic Cellular Respiration
Glycolysis and fermentation
Mitosis
asexual reproduction
Meiosis
sexual reproduction
Homozygous
AA
Heterozygous
Aa
Homozygous recessive
aa
Epistasis
interaction between two alleles which have different effects in combination than individually
Cytokinesis
end of mitosis (after telophase) and is marked by a single cell splitting into two daughter cells
