Question:
Breathing is the process of moving air into and out of the lungs. The process depends on a muscle called the diaphragm. This is a large, sheet-like muscle below the lungs. Inhaling, or breathing in, occurs when the diaphragm muscle tightens. This increases the size of the chest. This too decreases air pressure inside the lungs. This action allows air and gases to enter the lungs. Exhaling, or breathing out, occurs when the diaphragm muscle relaxes. This decreases the size of the chest. This increases air pressure inside the lungs. This action allows for air to leave the lungs. When you inhale, air enters the respiratory system through your nose and ends up in your lungs, where gas exchange with the blood takes place. What happens to the air along the way? In the nose, mucus and hairs trap any dust or other particles in the air. The air is also warmed and moistened. Next, air passes through a passageway that is connected to the windpipe. The air then finds its way to the lungs. In the chest, the windpipe splits so that air enters both the right and left lung. After reading the above, is "It decreases" the correct answer to the question "What happens to the size of the chest when the diaphragm muscle relaxes?"? OPTIONS:
- no
- yes

Answer:
yes

Question:
Living things need non-living matter as well as energy. What do you think matter is used for? One thing is to build bodies. They also need it to carry out the processes of life. Any non-living matter that living things need is called a nutrient. Carbon and nitrogen are examples of nutrients. Unlike energy, matter is recycled in ecosystems. You can see how in Figure 3.11. Decomposers release nutrients when they break down dead organisms. The nutrients are taken up by plants through their roots. The nutrients pass to primary consumers when they eat the plants. The nutrients pass to higher level consumers when they eat lower level consumers. When living things die, the cycle repeats. After reading the above, is "Living" the correct answer to the question "Are carbon and nitrogen considered living or non-living?"? OPTIONS:
- no
- yes

Answer:
no

Question:
Take a look at this train in Figure 1.11. It looks very futuristic. What do you notice about it? Did you notice that the train has no wheels? How can a train have no wheels? It doesn't need wheels. It actually floats, or levitates, just above the track. Magnets enable the train to do this. This is not a normal train. This is a maglev train. The word maglev stands for magnetic levitation. Because it has no wheels, there is no friction. Some magnets hold the train up. Other magnets are used to move the train forward. This train can go very fast. It can reach speeds up to 480 kilometers (300 miles) per hour! Magnets are pretty cool. What exactly is a magnet? How is it able to exert such force? After reading the above, is "Magnets are used to move it forward" the correct answer to the question "How does the train move?"? OPTIONS:
- no
- yes

Answer:
yes

Question:
Albanian was proved to be an Indo-European language in 1854 by the German philologist Franz Bopp. The Albanian language comprises its own branch of the Indo-European language family. Some scholars believe that Albanian derives from Illyrian while others claim that it derives from Daco-Thracian. (Illyrian and Daco-Thracian, however, might have been closely related languages; see Thraco-Illyrian.) Establishing longer relations, Albanian is often compared to Balto-Slavic on the one hand and Germanic on the other, both of which share a number of isoglosses with Albanian. Moreover, Albanian has undergone a vowel shift in which stressed, long o has fallen to a, much like in the former and opposite the latter. Likewise, Albanian has taken the old relative jos and innovatively used it exclusively to qualify adjectives, much in the way Balto-Slavic has used this word to provide the definite ending of adjectives. The cultural renaissance was first of all expressed through the development of the Albanian language in the area of church texts and publications, mainly of the Catholic region in the North, but also of the Orthodox in the South. The Protestant reforms invigorated hopes for the development of the local language and literary tradition when cleric Gjon Buzuku brought into the Albanian language the Catholic liturgy, trying to do for the Albanian language what Luther did for German. After reading the above, is "Cultural renaissance" the correct answer to the question "The Albanian language used jos to qualify adjectives and made what other shift?"? OPTIONS:
- no
- yes

Answer:
no
