Bright and color. Cone cells are the cells in the eye which allow for the perception of color, but are less sensitive to light than rod cells. Rod cells allow for relatively detailed vision in lower light levels, but are not sensitive to color. Fun fact: You have better night vision out of the corner of your eye (peripheral vision).

This is what happens when I leave a little... well"The report done by a company called 'Z-Tech' (sells shoes) states that, "the maximum force can equal up to three-and-a-half times body weight."Another report by Saucony reported forces of up to 3 times the body weight.I'd wager between 3x - 3.5x the body weight.

This is one of the hardest questions that humanity faces. Estimates are far and wide, and in the end, no one is certain for sure. Robert Birge from Syracuse University hypothesized that each neuron can contain about 1 bit of information. After some old fashioned counting and algebra, he says that the brain is capable of holding approx. 3 terabyes of information. Bear in mind, the brain can perform much more complex and advanced algorithms (without us knowing it!) to effectively compress more information. Other sources state that the brain can hold anywhere between 10-1,000 terabytes, due to us not fully knowing/understanding the amount of neurons and fuctions of synapses in the brain.

These are the typical gas volume % in a fart:N: 59%H: 21%CO2: 9%CH4: 7%O: 3%H2S & CH3SH: 1% (The odor makers, lol.)An average fart has a volume of 35.7 cubic cm.N: 21.0 mLH: 7.5 mLCO2: 3.2 mLCH4: 2.5 mLO: 1.1 mLH2S & CH3SH: 0.357 mLA perfect gas at STP has a molar volume of 22.4 L. That means a fart contains:N: 0.000938 molH: 0.000335 molCO2: 0.000143 molCH4:: 0.000112 molO: 0.000049 molH2S & CH3SH: 0.000016 molN, H, & O are all diatomic, forming molecules of N2, H2, and O2 at STP. The molecular weights are N2 (28), H2 (2), CO2 (44), CH4 (16), O2 (32). The molecular weight of CH3SH is 48.1. The molecular weight of H2S is 34.8. Meaning that the masses of the gases (rhyming skills) in a fart are...N2: 0.0263 gH2: 0.0003 gCO2: 0.0063 gCH4: 0.0018 gO2: 0.0016 gH2S & CH3SH: 0.0008 gThe total mass of a fart is 0.0371 gThe main energy value fuel-wise in a fart comes from the H2 CH[sub4[/sub]. You can get 142000 J per mol of H2 burned in O2, so the 0.000335 mol of H2 gas in a fart will yield 47.57 J. You can get 890400 J per mole of CH4 burned in O2, so the 0.000112 mol of CH4 will give us 99.72 J. The combined potential energy of a fart is 147.29 J. 6 years contain 189,341,712 sec, while 9 months contain 22,962,995 sec. If an average fart lasts 3 sec, the total energy value in J of farting for 6 years and 9 months would equal:3.127036029 × 1010J. That is a lot of energy.

If Josh were here, he'd probably say this:"Oxytocin is made in magnocellular neurosecretory cells of the supraoptic and paraventricular nuclei of the hypothalamus and is stored in Herring bodies at the axon terminals in the posterior pituitary."but he's not, so I'll say it.Short answer is hypothalamus, though.

Good question...Glucagon is a hormone released by the pancreas in order to moderate when blood glucose levels drop too low. It triggers a response in the liver that makes it 'flood' the circulatory system with glucose that was converted from previously stored glycogen. This ultimately raises the blood sugar level, preventing Hypoglycemia.

Type I the beta cells in the pancreas, the one’s responsible for producing the body’s insulin, are gradually destroyed. This is thought to be caused by the body’s own immune system attacking the beta cells. The immune system goes into overdrivei think that what my teacher said

If you didn't tell me to keep it simple, I'd hurl upon you a great 'ole Wall of China post. You see, all of my family, other than me, suffers from diabetes mellitus. Type 1 diabetes is essentially an autoimmune disease. The body 'attacks' the beta cells in the pancreas. The beta cells produce insulin, this is not good. Type 2 is the opposite. High blood sugar (glucose) levels are attributed to insulin resistance of cells.

I knew this without googling!Your nose. From your nose's bottom to it's top (where it meets your brow) is the same length as your thumb.
