Andy's bio 1

stigma, style, pistil, ovules

• Growth hormone: (somatotropin)
• Promotes bone and muscle growth
• Over production of GH in adults causes acromegaly....overgrowth of bone

growth occurs as organelles double

DNA replicated

occurs betweeen telophase 1 and prophase 2

• 3 o s -binds to 5'end of mRNA
• 5 o s- (2-3 sites to receive tRNA)

• A pairs with G etc.
• C pairs with T

• p=3q and p+q=1
• so 4q=1
• then q=.025 and p=.75
• 2(.025)(.75)=.375 or 37.5%

A vesicle at sperm's top that helps it penetrate egg

• night vision
• use rhodopsin as pigment (absorbs single wavelength)

the auricle (external ear) and the auditory canal

• simple ns ---nerve net
• limited centralization
• some jellyfish have clusters of cells that coordinate swimming

• one centrally located nucleus
• no striations

• UAA:
• UAG:
• UGA:

stimulus eliciting the behavior

• when stimulus no longer applied the response recovers overtime.
• Also can be the recovery of a conditioned response after extinction

a "neutral" stimuli is able to elicit the response even before conditioning, and hence is not really a neutral stimulus

gradual elimination of conditioned responses in absence of reinforcement "unlearning"

ability of a conditioned organism to respond to stimuli which are similar

following conditioning--stimuli more dissimilar to original conditioned stimulus elicits responses with dec. magnitude

transmits pulses away

cell body of neuron contains nucleus

structures that appear to be useless but had some ancestral function (ex. appendix, coccyx--useless bones at base of spine)

phage DNA reproduces itself using bacterum's genetic machinery and manufactures numerous progeny which then kill the cell (many lysed cells together can form a plaque)

2 subunits that bind only during protein synthesis

bind both the aa and its corresponding tRNA to form an amino acyl -tRNA complex
