How many shared electrons are in a single bond? two electrons Why potassium sulfide has a high melting point? It takes a lot of energy to overcome the strong electrostatic forces of attraction between oppositely charged ions, so ionic compounds have high melting and boiling points. The greater the charge on the ions, the stronger […]

What materials are poor insulators?
What materials are poor insulators? Conductors conduct electrical current very easily because of their free electrons. Insulators oppose electrical current and make poor conductors. Some common conductors are copper, aluminum, gold, and silver. Some common insulators are glass, air, plastic, rubber, and wood. Why does aluminum heat up faster than steel? Aluminum has much more […]

What do large pupils mean?
What do large pupils mean? When your body is under duress, your pupils dilate to improve your direct line of sight and peripheral vision. This allows you to better see what’s exciting you or evaluate a potential threat. Research has also found that people typically find those with larger pupils to be more attractive. Does […]
Which structure of the eye is responsible for color vision?
Which structure of the eye is responsible for color vision? Cones are responsible for sharp, detailed central vision and color vision and are clustered mainly in the macula. Rods are responsible for night and peripheral (side) vision. How does the retina process visual information? Visual processing and, ultimately, visual fields begin in the retina. Light […]
What is a complete life cycle?
What is a complete life cycle? Complete metamorphosis and incomplete metamorphosis are two growth types of insects where the body form of insects changes during their lifecycle. Complete metamorphosis consists of four stages: egg, larva, pupa, and adult. However, the incomplete metamorphosis consists of three stages: egg, nymph, and adult. Do female mosquitoes die after […]
