Are blue eyes from Vikings? Not only did many of the studied Vikings turn out to not be blond or blue-eyed, their genetic admixture shows they weren’t a distinct ethnic group but rather a mix of various other groups, “with ancestry from hunter-gatherers, farmers, and populations from the Eurasian steppe.” How can you tell if […]
What is advantage and disadvantage of series and parallel connection?
What is advantage and disadvantage of series and parallel connection? We know that the series circuits do not get heated easily….Complete answer: Advantages Disadvantages We know that the voltage remains constant in the parallel connection. Therefore, each component in the circuit gets the same amount of voltage. To construct the parallel connection, we need lots […]
Is it true most elements do not change?
Is it true most elements do not change? Most elements DO NOT change. Some ELEMENTS can decay over time. The rate of decay of any radioactive element CHANGES FREQUENTLY. Geologists use radioactive dating to determine THE ABSOLUTE AGES OF ROCKS. What are the two types of radioactive decay? The two most common modes of natural […]
What is the relationship between air pressure and altitude?
What is the relationship between air pressure and altitude? Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than […]
What type of mirror makes you look thinner?
What type of mirror makes you look thinner? “A completely flat mirror will show an image behind it of exactly the same shape and size as the actual object,” he told Apartment Therapy. “Slight curvature along only one axis can make a person look fat or skinny. “To make you look thin, your image needs […]
What are the 6 steps of action potential?
What are the 6 steps of action potential? An action potential has several phases; hypopolarization, depolarization, overshoot, repolarization and hyperpolarization. Hypopolarization is the initial increase of the membrane potential to the value of the threshold potential. What are the 5 steps of an action potential? The action potential can be divided into five phases: the […]
Why does grass look green when you look at it?
Why does grass look green when you look at it? Why Grass Is Green? Like many plants, grass produces a pigment called chlorophyll. This bright pigment absorbs blue and red light, reflecting green light back to your eyes. Is grass really green? Like many plants, most species of grass produce a bright pigment called chlorophyll. […]

The Five Basic Elements are Fire, Earth, Water, Metal, and Wood. Is hydrogen the most important element in the universe? Composed of a single proton and a […]
How does temperature affect direction of reaction?
How does temperature affect direction of reaction? A decrease in the temperature of a system favors the direction of the reaction that releases heat, the exothermic direction. Therefore, an increase in temperature of the system will favor the forward reaction. Conversely, a decrease in temperature will favor the reverse reaction. How does change in temperature […]
