Q: Answer the following question given this paragraph: The photo above represents water in three common states of matter. States of matter are different phases in which any given type of matter can exist. There are actually four well-known states of matter: solid, liquid, gas, and plasma. Plasma isn't represented in the iceberg photo, but the other three states of matter are. The iceberg itself consists of water in the solid state, and the lake consists of water in the liquid state. Q: What are the four well-known states of matter? A:
Answer: solid, liquid, gas, and plasma
Problem: OPTIONS:
- grass plants
- oxygen plants
- thermal plants
- vascular plants
Q: Answer the following question given this paragraph: Vascular Plants The vascular plants are the dominant and most conspicuous group of land plants. There are about 275,000 species of vascular plants, which represent more than 90 percent of Earth's vegetation. Several evolutionary innovations explain their success and their spread to so many habitats. Vascular Tissue: Xylem and Phloem The first fossils that show the presence of vascular tissue are dated to the Silurian period, about 430 million years ago. The simplest arrangement of conductive cells shows a pattern of xylem at the center surrounded by phloem. Xylem is the tissue responsible for long-distance transport of water and minerals, the transfer of water-soluble growth factors from the organs of synthesis to the target organs, and storage of water and nutrients. A second type of vascular tissue is phloem, which transports sugars, proteins, and other solutes through the plant. Phloem cells are divided into sieve elements, or conducting cells, and supportive tissue. Together, xylem and phloem tissues form the vascular system of plants. Q: What type of plant is the dominant group of land plants? A:
Answer: vascular plants
Problem: OPTIONS:
- cores
- currents
- motherlode
- veins
Q: Answer the following question given this paragraph: Underground water can be heated by magma. The hot water moves through cracks below Earth's surface. Hot water can hold more dissolved particles than cold water. The hot, salty solution has chemical reactions with the rocks around it. The water picks up more dissolved particles. As it flows through open spaces in rocks, the water deposits solid minerals. When a mineral fills cracks in rocks, the deposits are called "veins. " Figure below shows a white quartz vein. When the minerals are deposited in open spaces, large crystals grow. These rocks are called geodes. Figure below shows a "geode" that was formed when amethyst crystals grew in an open space in a rock. Q: What are the mineral deposits that fill in underground cracks called? A:
Answer:
veins
