- 31x10^1
5. 6x10^-3
Be able to convert between metric units
3.65 grams to milligrams
3650 microliters to liters
3650 mg
3.65 L
Know the monomers that construct proteins carbohydrates and nucleic acids
Proteins: amino acids
Carbohydrates : monosaccharides: glucose, galactose and fructose
Nucleic acid: nucleotides
Know what beers law states
When a light enters a solution the light is composed into single wavelengths. The white light is a mix picture of different wave lengths
Know the definitions:
Brownian movement Diffusion Net Diffusion Osmosis Net osmosis Osmotic pressure
- Accounts for process of diffusion
- Movement of molecules from a higher to lower concentration
- Distribution of solute molecules
- Diffusion of water
- Moves water molecules from higher to lower concentration
- Concentration of dissolved particles
Understand “tonicity” and the terms hypotonic, hypertonic and isotonic
Tonicity: Measure of osmotic pressure gradient
Hypertonic: cells contain a higher centration of NaCl
Hypotonic: lower concentration of NaCl
Isotonic: equal concentration
What are the four rules that govern the rate of diffusion
- temperature
- concentration
- distance
- material
Know the definition of: photoreceptors, mechanorecptors, thermoreceotors, osmoreceptors, chemoreceptors and nociceptors
Photoreceptors: responsible for light
Mechanoreceptors: sensitive to mechanical energy
Thermorecptors: sensitive to hot and cold
Osmoreceptors: detects change in concentration or body fluids
Chemoreceptors: sensitive to certain chemicals
Nocicptors: pain receptors
Know the term Emmetropin:
normal eye, perfect vision
Know the term: Myopia
eye too long, nearsighted
Know the term: Hyperopia
eye too short, farsighted
Know the term Astigmatism:
Blurred vision, misshapen cornea or lens
Know the term Nystagmus:
Involuntary eye movements, eye flickers neck and forth
Know the term Presbyopia:
Lense losses elasticity
Babinski
Foot was touched, toes curl up that means there’s damage, toes curl, there’s no damage to the neuropathways
Pupillary
Kept eyes closed, turn on the light then opened eyes, eyes constricted then doubled in size
Consensual
One eye opened, the other eye closed, one eye has a light shined on it but both constrict
Ciliospinal
Pinch on the neck and eyes dilated because the bodies sympathetic response
