Problem: OPTIONS:
- an alkali metal
- a halloid
- a metalloid
- an alloy
Q: Answer the following question given this paragraph: An alloy is a mixture of a metal with one or more other elements. The other elements may be metals, nonmetals, or both. An alloy is formed by melting a metal and dissolving the other elements in it. The molten solution is then allowed to cool and harden. Alloys generally have more useful properties than pure metals. Several examples of alloys are described and pictured below. You can learn about another alloythe amazing alloy called memory wireat the following URL. If you have braces on your teeth, you might even have this alloy in your mouth!. Q: What is a mixture of metal with one or more other elements? A:
Answer: an alloy

Problem:OPTIONS:
- transmission
- inclination
- oscillation
- acceleration

Answer the following question given this paragraph: Imagine the thrill of riding on a roller coaster like this one! The coaster slowly crawls to the top of the track and then flies down the other side. It also zooms around twists and turns at breakneck speeds. These changes in speed and direction are what make a roller coaster ride so exciting. Changes in speed or direction are called acceleration. Q: What is the term for changes in speed or direction, changes that make a roller coaster ride so exciting? A:
****
A: acceleration

Answer the following question given this paragraph: Fertilization Fertilization, pictured in Figure 43.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. The egg and sperm each contain one set of chromosomes. To ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. In mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. When a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. In placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma. Q: In mammals what does the zona pellucida protect? A:
OPTIONS:
- testes
- sperm
- fetus
- egg
egg

- reactions
- digestion
- melting
- photosynthesis Now, answer this question: Answer the following question given this paragraph: Almost all plants make food by photosynthesis. Only about 1 percent of the estimated 300,000 species of plants have lost the ability to photosynthesize. These other species are consumers, many of them predators. How do plants prey on other organisms? The Venus fly trap in Figure below shows one way this occurs. Q: What is the process by which almost all plants make food? A:
