Answer the following question given this paragraph: Both mammals and birds evolved endothermy. Endothermy means controlling body temperature within a narrow range from the inside through biochemical or physical means. For example, on a cold day, an endotherm may produce more body heat by increasing its rate of metabolism. On a hot day, it may give off more heat by increasing blood flow to the surface of the body. That way, some of the heat can radiate into the air from the body's surface. Endothermy requires more energy (and food) than ectothermy. However, it allows the animal to stay active regardless of the temperature outside.

Q: What term means controlling body temperature within a narrow range from the inside through biochemical or physical means? Choices: - exothermy - regulation - evaporation - endothermy A:
endothermy

Q: Answer the following question given this paragraph: Edema may be accompanied by varicose veins, especially in the superficial veins of the legs (Figure 20.8). This disorder arises when defective valves allow blood to accumulate within the veins, causing them to distend, twist, and become visible on the surface of the integument. Varicose veins may occur in both sexes, but are more common in women and are often related to pregnancy. More than simple cosmetic blemishes, varicose veins are often painful and sometimes itchy or throbbing. Without treatment, they tend to grow worse over time. The use of support hose, as well as elevating the feet and legs whenever possible, may be helpful in alleviating this condition. Laser surgery and interventional radiologic procedures can reduce the size and severity of varicose veins. Severe cases may require conventional surgery to remove the damaged vessels. As there are typically redundant circulation patterns, that is,. Q: Wich disorder arises when defective valves allow blood to accumulate within the veins? Choices: - vascular disease - bulging veins - cataracts veins - varicose veins A:
A: varicose veins
Question: Answer the following question given this paragraph: Magnetism produced by electricity is called electromagnetism . Today, electromagnetism is used in many electric devices. However, until electromagnetism was discovered, scientists thought that electricity and magnetism were unrelated. A Danish scientist named Hans Christian Oersted (pictured in the Figure below ) changed all that. He made the important discovery that electric current creates a magnetic field. But like many other important discoveries in science, Oersted's discovery was just a lucky accident. Q: What magnetism is produced by electricity? Choices: - excitation - diffusion - Charges - electromagnetism A:
Answer: electromagnetism

Answer the following question given this paragraph: Archaea that live in extremely hot environments are called thermophiles. Q: What are archaea that live in extremely hot environments called? Choices: - hypothermic - hemophiliacs - tardigrades - thermophiles A:
**Answer**
thermophiles
(Q).
Answer the following question given this paragraph: Human earlobes may be attached or free. You inherited the particular shape of your earlobes from your parents. Inherited traits are influenced by genes, which are passed on to offspring and future generations. Things not influenced by genes are not passed on to your offspring. Natural selection only operates on traits like earlobe shape that have a genetic basis, not on traits that are acquired, like a summer tan. Q: The shape of earlobes is an example of what kind of trait, which is influenced by genes and passed along through generations? Choices: - instinct - acquired trait - genetic disorder - inherited trait A:
(A).
inherited trait
