Human Anatomy: Vision 2

We’re going to return to Dr Ratfink for a few lectures. He constantly updates his uploads and I think there are 10 new ones. Today’s lecture is 41 minutes.

40% of solar radiation is in the vis range. IR does not excite electrons. UV disrupts organic molecules.

400-320 UVA
320-280 UVB
100-280 UVC

EM spectrum:cosmic, gamma, x rays, UV, vis, IR, microwave, UHF, VHG, FM, AM, AC.

Chlorophyll absorbes light and emits green. Has Mg in the center. Tetradentate molecule. Electrons in the Mg atom are excited. CLF absorbs mostly blue violet light and red. Grow lights are blue violet. If a molecule doesn’t absorb a color, it reflects it. Black absorbs all colors, white reflects all colors.

Prisms and raindrops break white light into it’s constituents. Carotene reflects orange red light.

Cones detect color and come in red, green and blue. The black spot is the pupil. The iris controls the opening. The cornea is the clear hard membrane. The retina has photoreceptors or sensory neurons that can recieve light. The optic nerve sends signals to the brain, cause APs to the brain.

Rods are for black and white.

Rhodopsin is retinol + opsin. Works like Chlorophyll. Vitamine A is retinol. Carotene forms two retinols. Lack of retinol causes “night blindness.”

Iodoxins are found in the cones. Color blindness is a sex based trait on the X chromosome. The color blind are allowed to drive because if a light is lit.

Infants are aware of smell and touch.

CRAVED – conceal, remove, available, valuable, enjoyable, disposable
CARVER – critical, accessible, recoverable, vunerable, effective, recognizable

C6H12O6 + 6O2 = 6CO2 + 6H2O + 36ATP
2C8H20 + 25O2 = 16CO2 + 18H2O

Air = 79% N2, 21% O2, Ar, Ne.
AFR air fuel ratio

Air: Fuel 14.7:1
14.7 lean
The lower the excess air, the richer the flame.
The higher the excess air, the leaner the flame.

Helicopter flight control inputs: cyclic-direction, collective altitude, pedals-nose direction, throttle.

14.7:1 Air/Fuel Mixture
“Money to get power, power to protect money”
Protein Denaturation: pH, heat, redox, detergents
Long Range: gravity, drag, wind
C6H12O6 → 2 C2H5OH+ 2 CO2 + heat
C6H12O6 = 2C2H5OH + 2CO2

Condensation reactions build chains. Dehydration reactions destroy chains. Making bonds releases energy, breaking bonds costs energy.
Colligative properties: vaper pressure depression, melting point depression, boiling point elevation, osmotic pressure.
Cuprite CU2O
C6H12O6 + 6O2 = 6CO2 + 6H2O + 36 ATP

B electric field strength
H magnetic field strength
E electric displacement field
D magnetic displacement field
A lactone is a cyclic ester
R-(O=S=O)-NH2 is a sulfonamide
Chalcocite CU2S
Chalcopyrite CuFeS2
Tenorite CuO
Hematite Fe2O3
Magnetite Fe3O4

NEIU – novelty, innovative, utility
-CH=CH2 vinyl
i = 1 + a(n-1)
n=number of ions in solution

Tropical Rainforest: floor, understory, canopy, emergent,
aurophillic bond 3A and 10kcal/mole
