Answer the following question given this paragraph: Meteorites provide clues about our solar system. Many were formed in the early solar system ( Figure below ). Some are from asteroids that have split apart. A few are rocks from nearby bodies like Mars. For this to happen, an asteroid smashed into Mars and sent up debris. A bit of the debris entered Earth's atmosphere as a meteor. Q: What astronomical phenomenon, formed of split asteroids or planetary rocks, provides clues about our solar system? Choices: - galaxies - comets - stars - meteorites A:
meteorites
Answer the following question given this paragraph: Other types of flatworms are parasitic. That means they live inside another organism, called a host, in order to get the food and energy they need. For example, tapeworms have a head-like area with tiny hooks and suckers (known as the scolex ) that help the worm attach to the intestines of an animal host ( Figure below ). There are over 11,000 species of parasitic flatworms. Q: What does parasitic mean? Choices: - mutual benefit - welcome guest - symbiotic - lives in host A:
lives in host
Q: Answer the following question given this paragraph: Q: Common among mammals and insects, pheromones are often related to what type of behavior? Choices: - aggressive - immune - cardiac - reproductive A:
A: reproductive
Question: Answer the following question given this paragraph: fossils and birds, specifically in the structure of the hip and wrist bones, as well as the presence of the wishbone, formed by the fusing of the clavicles. One important fossil of an animal intermediate to dinosaurs and birds is Archaeopteryx, which is from the Jurassic period (Figure 29.33). Archaeopteryx is important in establishing the relationship between birds and dinosaurs, because it is an intermediate fossil, meaning it has characteristics of both dinosaurs and birds. Some scientists propose classifying it as a bird, but others prefer to classify it as a dinosaur. The fossilized skeleton of Archaeopteryx looks like that of a dinosaur, and it had teeth whereas birds do not, but it also had feathers modified for flight, a trait associated only with birds among modern animals. Fossils of older feathered dinosaurs exist, but the feathers do not have the characteristics of flight feathers. Q: The fossilized skeleton of archaeopteryx looks like that of a dinosaur, but it had what structures modified for flight, a trait associated only with birds among modern animals? Choices: - fingers - claws - beaks - feathers A:
Answer: feathers

Answer the following question given this paragraph: Charging an object by touching it with another charged object is called charging by conduction. By bringing a charged object into contact with an uncharged object, some electrons will migrate to even out the charge on both objects. Charging by conduction gives the previously uncharged object a permanent charge. An uncharged object can also be charged using a method called charging by induction . This process allows a change in charge without actually touching the charged and uncharged objects to each other. Imagine a negatively charged rod held near the knob, but not touching. If we place a finger on the knob, some of the electrons will escape into our body, instead of down the stem and into the leaves. When both our finger and the negatively charged rod are removed, the previously uncharged electroscope now has a slight positive charge. It was charged by induction. Notice that charging by induction causes the newly charged object to have the opposite charge as the originally charged object, while charging by conduction gives them both the same charge. Q: What is the name for the process of charging an object by touching it with another charged object? Choices: - charging by connection - charging by convection - charging by transfer - charging by conduction A:
**Answer**
charging by conduction
