What is photosynthesis answer in one line? Photosynthesis is the process by which plants and some microorganisms make substances like carbohydrates. It is an endothermic (takes in heat) chemical process that uses sunlight to turn carbon dioxide into sugars. The sugars are used by the cell as energy, and to build other kinds of molecules. […]

Are we made of waves? Radio waves are obviously waves. Only when we come close do we notice that this object is actually a wave. Summary: With quantum theory, we find a beautiful unification: instead of there being two fundamental entities (particles and waves), there is only one fundamental entity: waves. Does Matter diffract? All […]

What type of object a chair a painting and a shoe are? Objects like a chair, a painting, or a shoe do not have their own light. We see these when light from a luminous object (like the Sun, a torch, or an electric light) falls on these and then travels towards our eye. Why […]

What are the factors affecting the height of the waves? Wave height is affected by wind speed, wind duration (or how long the wind blows), and fetch, which is the distance over water that the wind blows in a single direction. If wind speed is slow, only small waves result, regardless of wind duration or […]

Is pitch and note the same? Pitch is the high or low frequency of a sound. When you sing, you create pitch because your vocal cords vibrate at a certain speed. Notes are musical symbols that indicate the location of a pitch. Tone is the color or timbre of pitch. Can a sound have no […]

What are five ways to make an observation? Explain that an observation is information we gather about something by using our senses. List the five senses of sight, hearing, taste, touch, and smell. Use their senses to make observations about things in the classroom. What are the direct observation methods? Observations can also be either […]

What is the reason that air tanks must be drained? To prevent too much moisture and oil from collecting, the air tanks must be drained regularly. Air pressure gauges indicate air pressure in the vehicle’s dual service (primary and secondary) air tanks. Safety valves prevent over-pressure of the air brake system. Why must air tanks […]

Can high voltage low current kill you? No, it’s the current that kills you. It kills you by putting a current signal through your heart, which interferes with its normal operation. The high voltage is necessary to penetrate the skin. How many volts can Denki produce? This move was first used against members of the […]

What is the relationship between valence electrons and bonding? Valence electrons are outer shell electrons with an atom and can participate in the formation of chemical bonds. In single covalent bonds, typically both atoms in the bond contribute one valence electron in order to form a shared pair. The ground state of an atom is […]

What is the correct pathway for vision? The visual pathway consists of the retina, optic nerves, optic chiasm, optic tracts, lateral geniculate bodies, optic radiations, and visual cortex. The pathway is, effectively, part of the central nervous system because the retinae have their embryological origins in extensions of the diencephalon. Which controls the amount of […]
