What are the 2 biological effects of ionizing radiation? The biological effects of ionizing radiation are due to two effects it has on cells: interference with cell reproduction, and destruction of cell function. Which radiation is responsible for oncogenic transformation? Class I PI3K consists of four isoforms, PI3K α, β, γ, and δ, each with […]
What are the 4 types of science?
What are the 4 types of science? There are four major branches of science; each branch is categorized in different type of subjects that covers different areas of studies such us chemistry, physics, math, astronomy etc. The four major branches of science are, Mathematics and logic, biological science, physical science and social science. What is […]
What is the best surface to cut pizza on?
What is the best surface to cut pizza on? Wooden cutting boards can be made from many different types of wood. To avoid scratches, and to make sure you have a long lasting pizza board, the best choice is a hardwood, such as, maple, oak, teak or walnut. Another good option is bamboo, that technically […]
Do convergent boundaries cause volcanoes?
Do convergent boundaries cause volcanoes? If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. The new magma (molten rock) rises and may erupt violently to form volcanoes, often building arcs of islands along the convergent boundary. Where […]
What are the three common fault types?
What are the three common fault types? There are three kinds of faults: strike-slip, normal and thrust (reverse) faults, said Nicholas van der Elst, a seismologist at Columbia University’s Lamont-Doherty Earth Observatory in Palisades, New York. What is the difference between reverse fault and normal fault? In a reverse fault, the hanging wall displaces upward, […]
What is the best solvent for recrystallization?
What is the best solvent for recrystallization? For a solvent pair, the first solvent should readily dissolve the solid. The second solvent must have a lower solubility for the solute and be miscible with the first solvent. Common solvent pairs include ethyl acetate and hexane, toluene and hexane, methanol and dichloromethane, and water and ethanol. […]
What is the shortest period of time?
What is the shortest period of time? Scientists have measured the shortest unit of time ever: the time it takes a light particle to cross a hydrogen molecule. That time, for the record, is 247 zeptoseconds. A zeptosecond is a trillionth of a billionth of a second, or a decimal point followed by 20 zeroes […]
What does the Highway Code say about reversing?
What are two ways to increase the resistance in a wire?
What are two ways to increase the resistance in a wire? length – longer wires have greater resistance. thickness – smaller diameter wires have greater resistance. temperature – heating a wire increases its resistance. What are three ways to decrease resistance in a wire? Changing the material, increasing the cross section area, lowering the temperature, […]
Why is oxygen not suitable for a light bulb?
Why is oxygen not suitable for a light bulb? A light bulb full of oxygen would not work well, as the bulb’s tungsten filament, if it ignited at all, would burn very brightly and short out quickly. Oxygen is flammable, a decided fire hazard that would ignite the bulb’s insides. Why are light bulbs filled […]
