Answer the following question given this paragraph: Coal is a black or brownish-black rock that burns easily ( Figure below ). Most coal is sedimentary rock. The hardest type of coal, anthracite, is a metamorphic rock. That is because it is exposed to higher temperature and pressure as it forms. Coal is mostly carbon, but some other elements can be found in coal, including sulfur. Q: What element makes up the majority of coal? Choices: - iron - lead - silicon - carbon A:
carbon

Answer the following question given this paragraph: Layers of Human Skin. The outer layer of the skin is the epidermis, and the inner layer is the dermis. Most skin structures originate in the dermis. Q: Where do most skin structures originate in? Choices: - epidermis - cuticle - hypodermis - dermis A:
(Answer)
dermis
Ques: Answer the following question given this paragraph: An inclined plane is a simple machine consisting of a sloping surface that connects lower and higher elevations. The ideal mechanical advantage of an inclined plane is always greater than 1. Q: What do you call a simple machine consisting of a sloping surface that connects lower and higher elevations? Choices: - lever - wedge - jack - inclined plane A:
Ans: inclined plane
(Q).
Answer the following question given this paragraph: The frontal lobe is located at the front of the brain, over the eyes. This lobe contains the olfactory bulb, which processes smells. The frontal lobe also contains the motor cortex, which is important for planning and implementing movement. Areas within the motor cortex map to different muscle groups, and there is some organization to this map, as shown in Figure 35.22. For example, the neurons that control movement of the fingers are next to the neurons that control movement of the hand. Neurons in the frontal lobe also control cognitive functions like maintaining attention, speech, and decisionmaking. Studies of humans who have damaged their frontal lobes show that parts of this area are involved in personality, socialization, and assessing risk. Q: What is the bulb called in the frontal lobe that processes smells? Choices: - peripheral bulb - auditory bulb - sensory bulb - olfactory bulb A:
(A).
olfactory bulb
Ques:Answer the following question given this paragraph: Note that in Table 14.3, the best thermal conductorssilver, copper, gold, and aluminumare also the best electrical conductors, again related to the density of free electrons in them. Cooking utensils are typically made from good conductors. Q: The best thermal conductors are also the best conductors of what, which is also related to the density of free electrons in them? Choices: - light - pollution - sound - electricity A:

Ans:electricity
Ques: Answer the following question given this paragraph: Another major cause of extinction is global warming , which is also known as global climate change. During the past century, the Earth's average temperature has risen by almost 1C (about 1.3F). You may not think that is significant, but to organisms that live in the wild and are constantly adapting to their environments, any climate change can be hazardous. Recall that burning fossil fuels releases gasses into the atmosphere that warm the Earth. Our increased use of fossil fuels, such as coal and oil, is changing the Earth's climate. Any long-term change in the climate can destroy the habitat of a species. Even a brief change in climate may be too stressful for an organism to survive. For example, if the seas increase in temperature, even briefly, it may be too warm for certain types of fish to reproduce. Q: Another major cause of extinction is global warming , which is also known as? Choices: - sudden climate change - rapid climate change - regional climate change - global climate change A:
Ans:
global climate change
