Why are there two tides each day?
Why are there two tides each day? This occurs because the moon revolves around the Earth in the same direction that the Earth is rotating on its axis. Since the Earth rotates through two tidal “bulges” every lunar day, we experience two high and two low tides every 24 hours and 50 minutes. Is it […]
What is called synthesis?
What is called synthesis? In chemistry, chemical synthesis (or combination) is the artificial execution of useful chemical reactions to obtain one or several products. This occurs by physical and chemical manipulations usually involving one or more reactions. The amount produced in chemical synthesis is known as the reaction yield. What is the net ionic equation? […]

What is the correct pathway of light through the eye?
What is the correct pathway of light through the eye? Light passes through the front of the eye (cornea) to the lens. The cornea and the lens help to focus the light rays onto the back of the eye (retina). The cells in the retina absorb and convert the light to electrochemical impulses which are […]
What are the examples of malleability?
What are the examples of malleability? Examples of malleable metals are gold, iron, aluminum, copper, silver, and lead. Gold and silver are highly malleable. When a piece of hot iron is hammered it takes the shape of a sheet. How do you define hardness? Hardness is the ability of a material to resist deformation, which […]

What happens if lightning hits a boat?
What happens if lightning hits a boat? But a direct hit usually causes more obvious and substantial damage. When a boat gets struck, lightning is trying to find its way to ground, typically the water around and under the boat. Though mast-mounted components are the most likely to be destroyed, anything on the boat that […]
What is the most dangerous mutation?
What is the most dangerous mutation? Insertion or deletion results in a frame-shift that changes the reading of subsequent codons and, therefore, alters the entire amino acid sequence that follows the mutation, insertions and deletions are usually more harmful than a substitution in which only a single amino acid is altered. What are examples of […]
