Q: What take the shape of their container, and are relatively easy to compress? Read this paragraph and choose the correct option from the provided answers: The story is quite different for gases. Gases take the shape of their container, and they are relatively easy to compress. There are fewer gas particles per unit volume than for the same substance in the liquid or solid form. In fact, the liquid form of a given material is generally several hundred times more dense than the gas form at normal pressures. Despite the large amounts of empty space, a sample of a gas contains many particles moving around, colliding and imparting force on their surroundings. For example, in a one mole sample of gas at 0C and 1 atm of pressure, each cubic centimeter contains roughly 2.7 10 19 molecules. Each molecule participates in several billion collisions every second, moving only about 10-100 nanometers between collisions. Additionally, these gas particles move at very high speeds. For example, at 25C, the average speed of hydrogen molecules in a sample of hydrogen gas is 1960 m/s. Choices: - molecules - semi-fluids - fluids - gases A:
gases

Q: What is the first classification of igneous rocks? Read this paragraph and choose the correct option from the provided answers: Igneous rocks are classified first by composition. Categories go from from felsic to ultramafic. Color can indicate composition. Choices: - size - color - weight - composition A:
composition

Q: Q: In which kind of species do open circulatory systems serve additional functions? Read this paragraph and choose the correct option from the provided answers: Choices: - some apes - some seedlings - some earthworms - some invertebrates A:
A: some invertebrates

Question: Q: How do plants grow? Read this paragraph and choose the correct option from the provided answers: Most plants continue to grow throughout their lives. Like other multicellular organisms, plants grow through a combination of cell growth and cell division. Cell growth increases cell size. Cell division increases the number of cells. Choices: - through cell growth and sexual reproduction - through mitosis and cell division - through pollination and cell division - through cell growth and cell division A:
Answer: through cell growth and cell division

Q: The entire range of light that can be seen by the human eye without aid is known as what kind of light? Read this paragraph and choose the correct option from the provided answers: Why is this picture of a cat so colorful? No cat looks like this to the human eye. The picture was taken with a special camera that senses infrared light. This is a form of energy given off by warm objects. Areas that appear yellow are the warmest, and areas that appear purple are the coolest. The picture shows that the cat's eyes are the warmest part of its head. Why can't people see images like this without a camera? The answer has to do with the wavelengths of infrared light. Its wavelengths are too long for the human eye to detect. In fact, the human eye can detect light only in a very narrow range of wavelengths, called visible light. You'll learn more about infrared light, visible light, and other forms of electromagnetic radiation in this chapter. Choices: - white light - colored light - infrared light - visible light A:
**Answer**
visible light

Q: On what part of bones would you expect to find cartilage? Read this paragraph and choose the correct option from the provided answers: The adult human skeleton has 206 bones, some of which are named below ( Figure below ). Bones are made up of living tissue. They contain many different types of tissues. Cartilage, a dense connective tissue, is found at the end of bones and is made of tough protein fibers. Cartilage creates smooth surfaces for the movement of bones that are next to each other, like the bones of the knee. Choices: - interior - marrow - exterior - end A:
**Answer**
end
