What are the materials needed for photosynthesis? To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. for photosynthesis. Carbon dioxide enters through tiny holes in a plant’s leaves, flowers, branches, stems, and roots. Plants also require water to make their food. What is the photosynthesis equation? The process of photosynthesis is commonly […]

What is p the probability of success What is 1 p the probability of failure? p = probability of success, q = probability of failure = 1 – p. Note that p + q = 1. In statistical terms, A Bernoulli trial is each repetition of an experiment involving only 2 outcomes. We are often […]

What are the types of screw threads? Clamp screws come in many forms. There are Standard threads, ACME threads, Buttress threads, and Square threads. Each of these threads may be used in clamps and vises for different reasons. What is the use of screw? The most common uses of screws are to hold objects together […]

Is rock a fossil? Fossils are the preserved remains, or traces of remains, of ancient organisms. Fossils are not the remains of the organism itself! They are rocks. Bones, shells, feathers, and leaves can all become fossils. Who is the most famous paleontologist in the world? Jack Horner Do you need a PhD to be […]

Is gold used in semiconductors? A good conductor of heat and electricity, it is also the most malleable and ductile of all metals. Gold is used in many aspects of semiconductor manufacturing, particularly in the assembly or packaging processes. Its most widespread use is in wirebonding. Why is gold used in motherboards? Principally used in […]

How do I filter rows instead of columns in Excel? So you can follow the steps. Select the area where you want to sort values. Click the button “Sort & Filter” in the ribbon. In the menu, click the option “Custom Sort”. In this window, click the “Options”. Now you will see another new window. […]

At what temperature does all motion cease theoretically? A temperature scale whose zero point is absolute zero, the temperature of 0 entropy at which all molecular motion stops, -273.15° C. The size of a degree Kelvin is the same as the size of a degree Celsius. Which temperature does all molecular motion steps? Step by […]

Can we land on an asteroid? Landing. Asteroids are not large enough to produce significant gravity, making it difficult to land a spacecraft. This technology allowed for the orientation control and orbit control of the spacecraft that guided it to land on Ryugu. How could we redirect an asteroid? Under consideration for deflecting an asteroid […]

How much food is being wasted per year or every 10 years? An estimated 1.3 billion tonnes of food is wasted globally each year, one third of all food produced for human consumption. In ten years, the United States will waste the equivalent of 66 tons of food per second across the globe. What country […]

Does Heat travel up or down? “Heat” does not travel up. Heat can travel in all directions. The direction heat travels depends on the specifics of a system not in thermal equilibrium. In contrast, “hot air” on earth’s surface tends to go up. What material reflects the most heat? Note that a metal will only […]
