Answer the following question given this paragraph: Ungulates include hoofed animals, such as deer, sheep, goats, pigs, buffalo, elephants and giraffes ( Figure below ). These mammals use their hoofs to sustain their whole body weight while moving. Hoofs are formed by a thick nail rolled around the tip of the toe. Q: In the mammal family, what is the name for hoofed animals, such as deer, sheep, goats, pigs, buffalo, elephants and giraffes? Choices: - primates - bovines - rodents - ungulates A:
ungulates
(Question)
Answer the following question given this paragraph: Not really. Like all mammals, polar bears maintain a stable internal temperature. They do not need to stay warm by lying in the sun. This allows them to live in cold climates. Q: The ability to maintain a stable internal temperature, despite the climate, is exhibited by members of what animal group? Choices: - fish - parasites - reptiles - mammals A:
(Answer)
mammals
Ques: Answer the following question given this paragraph: The use of electric current to encode information is called electronics. Electronic signals may be digital or analog signals. Both types of signals encode information by changing the voltage of an electric current, but they do so in different ways. Q: What do we call use of electric current to encode information? Choices: - products - metals - ferious - electronics A:
Ans: electronics
(Q).
Answer the following question given this paragraph: We now know how variation in traits is inherited. Variation in traits is controlled by different alleles for genes. Alleles, in turn, are passed to gametes and then to offspring. Evolution occurs because of changes in alleles over time. How long a time? That depends on the time scale of evolution you consider. Q: Evolution occurs because of changes in what over time? Choices: - mitochondria - genomes - atoms - alleles A:
(A).
alleles
Ques:Answer the following question given this paragraph: The highway above switches back and forth as it climbs up the steep hillside. The much gentler slope of the road makes it easier for vehicles to reach the top of the mountain. The highway is an example of an inclined plane. Q: A highway that switches back and forth as it climbs up a steep hillside, yeilding a much gentler slope, is an example of what simple machine? Choices: - lever - pulley - wheel - inclined plane A:

Ans:inclined plane
Answer the following question given this paragraph: Anabolic Steroids The endocrine system can be exploited for illegal or unethical purposes. A prominent example of this is the use of steroid drugs by professional athletes. Commonly used for performance enhancement, anabolic steroids are synthetic versions of the male sex hormone, testosterone. By boosting natural levels of this hormone, athletes experience increased muscle mass. Synthetic versions of human growth hormone are also used to build muscle mass. The use of performance-enhancing drugs is banned by all major collegiate and professional sports organizations in the United States because they impart an unfair advantage to athletes who take them. In addition, the drugs can cause significant and dangerous side effects. For example, anabolic steroid use can increase cholesterol levels, raise blood pressure, and damage the liver. Altered testosterone levels (both too low or too high) have been implicated in causing structural damage to the heart, and increasing the risk for cardiac arrhythmias, heart attacks, congestive heart failure, and sudden death. Paradoxically, steroids can have a feminizing effect in males, including shriveled testicles and enlarged breast tissue. In females, their use can cause masculinizing effects such as an enlarged clitoris and growth of facial hair. In both sexes, their use can promote increased aggression (commonly known as "roid-rage"), depression, sleep disturbances, severe acne, and infertility. Q: What performance-enhancing drugs are synthetic versions of the male sex hormone, testosterone? Choices: - catabolic steroids - progesterone - estrogen - anabolic steroids A:
anabolic steroids
