What makes a reaction dangerous? Even slow reactions can be hazardous if they involve large amounts of material or if the heat and gases are confined, such as in a sealed storage drum. Drums that are swollen and distorted from over-pressurization are potentially very dangerous. They may rupture at any time without warning and release […]
What can be the cause of weakening muscles and kidney function?
What can be the cause of weakening muscles and kidney function? When muscle is damaged, a protein called myoglobin is released into the bloodstream. It is then filtered out of the body by the kidneys. Myoglobin breaks down into substances that can damage kidney cells. Rhabdomyolysis may be caused by injury or any other condition […]
Why do we use copper and not silver or graphite for electrical wiring in our houses give a reason for each?
Why do we use copper and not silver or graphite for electrical wiring in our houses give a reason for each? Unlike silver which in its natural state is a metal like copper, the form of graphite with very low resistivity to compare with copper is graphene. Technically its not a metal which can be […]
What causes trichromatic vision?
What causes trichromatic vision? The normal explanation of trichromacy is that the organism’s retina contains three types of color receptors (called cone cells in vertebrates) with different absorption spectra. In actuality the number of such receptor types may be greater than three, since different types may be active at different light intensities. What causes Tetrachromatic […]
Is diorite volcanic or plutonic?
Is diorite volcanic or plutonic? It is produced in volcanic arcs, and in mountain building where it can occur in large volumes as batholiths in the roots of mountains (e.g. Scotland, Norway). Because it is commonly speckled black and white, it is often referred to as “salt and pepper” rock. Diorite is the plutonic equivalent […]
What kind of microscope can see a Tardigrades?
What kind of microscope can see a Tardigrades? Monocular Compound Microscope Can Tardigrades live in the human body? Despite their reputation, tardigrades aren’t entirely indestructible. They cannot survive the trip through the human digestive tract since our stomach acid disintegrates the flesh of the tardigrade without much trouble, so eating one wouldn’t do any harm. […]
Why do atoms get bigger across a period?
Why do atoms get bigger across a period? 4 Answers. As you move from left to right across a period, the number of protons in the nucleus increases. These lower energy levels shield the valence electrons from the attractive effects of the atom’s nucleus, so the atomic radius gets larger. Why do atoms get smaller […]
How fast can a freight train accelerate?
How fast can a freight train accelerate? The final factor and one frequently overlooked is the tractive effort required for acceleration of the train. It takes about 10 pounds per ton to accelerate to a speed of 6 miles per hour in one minute or 12 miles per hour in two minutes, a reasonable rate […]
Do air bubbles get bigger?
How can you tell the difference between hypovolemia and dehydration?
How can you tell the difference between hypovolemia and dehydration? HYPOVOLEMIA refers to any condition in which the extracellular fluid volume is reduced, and results in decreased tissue perfusion. It can be produced by either salt and water loss (e.g. with vomiting, diarrhea, diuretics, or 3rd spacing) OR by water loss alone, which is termed […]
