How does evolution via artificial selection differ from evolution via natural selection?
If it evolution via natural selection then it is the natural that selects what traits should be passed on, for example having leg is better land animals then organisms that have leg will survive and ones that don't will die, this is natural selection, of course this happens over a long period of time. Evolution via artificial selection is where human selects the animal, perhaps the mutation may be eliminated in the wild but we think that it is suitable for our life so we mass produce the organism with that desirable trait. Like peas, ancient peas have to explode out of their pods to spread seeds but that is not good for us but then maybe one day a mutation occured and the pea pod will not explode, then we take it and breed many of that.
Metamorphic Rocks form from existing rocks that have been heated and squeezed?
Yes, a metamorphic rocks is an existing rock that has been transformed via heat and pressure.
What converts pressure waves in the cochlea into nerve impulses?
The hair cells in the cochlea convert pressure waves into nerve impulses. When sound vibrations move through the cochlear fluid, they cause the hair cells to bend. This bending opens ion channels, which triggers a nerve impulse that is sent to the brain via the auditory nerve.
What propels blood to the tissues?
Arterial pressure pushes blood through the body. Blood, as a heterogeneous mixture of cells, liquid, and other substances, is pushed through blood vessels via the pumping of the heart. It perfuses through the arteries, arterioles, capillaries, tissues, venules, veins, and back to the heart via the pressure of the blood through these blood vessels. At certain points along the way, pressure can increase or decrease, based on the diameter of the vessels through which it travels, as well as the presence or absence of any blockages. Vasoconstriction, vasodilation, and fluid balance help to maintain blood pressure accordingly.
Which systems does the brain interact with?
The brain interacts with the nervous system (including sensory organs), endocrine system (via hormones), immune system (through neuroimmune interactions), and the cardiovascular system (regulating blood flow and pressure).
How do you explode TNT in Minecraft?
TNT can be ignited by using a Flint and Steel on it, or providing charge via a switch (lever, pressure plate, etc) or by an active redstone current.
Who can explain clearly how to get redstone lamps and explode TNT on minecraft?
To get a Redstone Lamp, you need one block of Glowstone, and four units of Redstone dust. Place them in a '+' configuration with the Glowstone Block in the middle.To explode TNT you can light it with Flint and Steel, or a Fire Charge. Or you can provide it with charge via redstone circuitry or levers/pressure plates. For example if you put a block next to it and put a lever or button on it, you will prime the TNT by activating it. Or you can buy the TNT in the ground with one block above, and a pressure plate on top if that. The TNT will explode if the pressure plate is stepped on.
How do venous pressures compare to arterial pressures?
Much lower... because arterial walls get their pressure via force of the left ventricle pumping into the arteries. Veins are not exposed to such force and get their pressure via muscle pumps.Much lower... because arterial walls get their pressure via force of the left ventricle pumping into the arteries.

How do cows explode?
Yes i believe that a cow could explode but it would be kind of complicated to blow up a cow i mean you would have to light dynamite with a cow beside it like laying on it and light the fuse and stuff but yah a cow can blow up... i wouldn't suggest you trying to blow up a cow but yah....
What is throttle pressure regulator of a steam turbine?
Essentially its the pressure prior to entering the turbine chamber via the MSV (main stop valve)
Can you administer drugs via arterial line?
Yes, but the pressure must be high enough to allow it to flow.
How many decibels can the ear drum withstand?
At max, 199. 200 will kill you do to the brain not being able to handle such an intense vibration. Your brain will explode internally and you will die via massive brain bleeding.
What is the internal pressure of hot tub filters?
Hot tub filters contain sand and gravel to filter our impurities in the water via a high pressure nozzle. The pressure must be high enough otherwise circulation problems may occur.
How does blood pressure affects the administration of IV narcotics?
High blood pressure would lower the administration rate of a gravity IV drip. It would have no real impact on injection via syringe.
Are there any websites that could help me find blood pressure and cholesterol?
There is no website out there that can tell you what your blood pressure or cholesterol levels are. You have to go to the doctor, where they'll check for you, via bloodwork and a general physical.
Human blood pressure is highest in what vessel?
Blood pressure is highest in the arteries.
What do the numbers 120 over 80 refer to?
blood pressure or BP, 120 refers to the amount of pressure produced when the ventricles of the heart contract and 80 refers to the pressure in the blood vessels (normally measured via the brachial artery in the humerus) when the heart is at resting. 120/80 is known as the ideal blood pressure.
