Q: A plane mirror has a flat reflective surface and forms only which kind of images? Read this paragraph and choose the correct option from the provided answers: Most mirrors are plane mirrors. A plane mirror has a flat reflective surface and forms only virtual images. The image formed by a plane mirror is also life sized. But something is different about the image compared with the real object in front of the mirror. Left and right are reversed. Look at the man shaving in Figure below . He is using his right hand to hold the razor, but his image appears to be holding the razor in the left hand. Almost all plane mirrors reverse left and right in this way. Choices: - enlarged - spherical - reduced - virtual A:
virtual

Q: Q: What are winds that blow over a limited area called? Read this paragraph and choose the correct option from the provided answers: Local winds are winds that blow over a limited area. Local winds blow between small low and high pressure systems. They are influenced by local geography. Nearness to an ocean, lake, or mountain range can affect local winds. Some examples are found below. Local winds can affect the weather and climate of a region. Choices: - trade winds - Planetary Winds - Periodic Winds - local winds A:
A: local winds

Question: Q: What is a diagram that shows a single way that energy flows throughout an ecosystem? Read this paragraph and choose the correct option from the provided answers: A food chain is a simple diagram that shows one way energy flows through an ecosystem. Pictured below is an example of a food chain ( Figure below ). Producers form the base of all food chains. The consumers that eat producers are called primary consumers.

Q: Europa and titan are names of what kind of celestial objects? Read this paragraph and choose the correct option from the provided answers: Saturn's largest moon, Titan, is about one and a half times the size of Earth's moon. Titan is even larger than the planet Mercury. The picture below compares the size of Titan to Earth ( Figure below ). Scientists are very interested in Titan. The moon has an atmosphere that is thought to be like Earth's first atmosphere with nitrogen and methane. This atmosphere was around before life developed on Earth. Like Jupiter's moon, Europa, Titan may have a layer of liquid water under a layer of ice. Scientists now think that there are lakes on Titan's surface. Don't take a dip, though. These lakes contain liquid methane and ethane instead of water! Methane and ethane are compounds found in natural gas. Choices: - galaxies - stars - asteroids - moons A:
**Answer**
moons

Q: What is formed when each sodium atom donates its single valence electron to a chlorine atom? Read this paragraph and choose the correct option from the provided answers: Ionic bonds are possible because the elements involved have either donated or accepted one or more electrons. Sodium chloride is formed when each sodium atom donates its single valence electron to a chlorine atom. As a result, both ions have a noble gas configuration, and an attraction is formed between the positive sodium ions and the negative chloride ions. Choices: - carbon chloride - nitrogen chloride - trioxide chloride - sodium chloride A:
sodium chloride
