Answer the following question given this paragraph: The product of a wave's wavelength () and its frequency (), , is the speed of the wave. Thus, for electromagnetic radiation in a vacuum: c = 2.998 10 8 ms 1 = Wavelength and frequency are inversely proportional: As the wavelength increases, the frequency decreases. The inverse proportionality is illustrated in Figure 6.3. This figure also shows the electromagnetic spectrum, the range of all types of electromagnetic radiation. Each of the various colors of visible light has specific frequencies and wavelengths associated with them, and you can see that visible light makes up only a small portion of the electromagnetic spectrum. Because the technologies developed to work in various parts of the electromagnetic spectrum are different, for reasons of convenience and historical legacies, different units are typically used for different parts of the spectrum. For example, radio waves are usually specified as frequencies (typically in units of MHz), while the visible region is usually specified in wavelengths (typically in units of nm or angstroms). Q: The product of a wave's wavelength and its frequency is what? A:

OPTIONS:
- trough
- velocity
- amplitude
- speed

Answer: speed

Problem: OPTIONS:
- copper
- aluminum
- tin
- mercury
Q: Answer the following question given this paragraph: The elements mercury, gold, and copper display properties that are common of metals. Mercury ( left ) is the only metal that is a liquid at room temperature. Even in its liquid form, it still has a high luster. Gold ( middle ) is malleable and can be formed into very thin sheets called gold leaf. Because copper ( right ) is ductile, inexpensive, and a good conductor, it is used extensively in electrical wiring. Q: What is the only metal that is a liquid at room temperature? A:
Answer: mercury

Problem:OPTIONS:

- atmospheric energy
- thermal energy

Answer the following question given this paragraph: The atoms that make up matter are in constant motion, so they have kinetic energy. All that motion gives matter thermal energy. Thermal energy is defined as the total kinetic energy of all the atoms that make up an object. It depends on how fast the atoms are moving and how many atoms the object has. Therefore, an object with more mass has greater thermal energy than an object with less mass, even if their individual atoms are moving at the same speed. You can see an example of this in Figure below . Q: What kind of energy constitutes the total kinetic energy of all the atoms that make up an object? A:
****
A: thermal energy

Answer the following question given this paragraph: Lipids are biochemical compounds that living things use to store energy and make cell membranes. Types of lipids include fats, oils, and phospholipids. Q: What are biochemical compounds that living things use to store energy and make cell membranes? A:
OPTIONS:
- carbohydrates
- proteins
- nucleic acid
- lipids

Answer the following question given this paragraph: Animal Bioenergetics All animals must obtain their energy from food they ingest or absorb. These nutrients are converted to adenosine triphosphate (ATP) for short-term storage and use by all cells. Some animals store energy for slightly longer times as glycogen, and others store energy for much longer times in the form of triglycerides housed in specialized adipose tissues. No energy system is one hundred percent efficient, and an animal's metabolism produces waste energy in the form of heat. If an animal can conserve that heat and maintain a relatively constant body temperature, it is classified as a warm-blooded animal and called an endotherm. The insulation used to conserve the body heat comes in the forms of fur, fat, or feathers. The absence of insulation in ectothermic animals increases their dependence on the environment for body heat. The amount of energy expended by an animal over a specific time is called its metabolic rate. The rate is measured variously in joules, calories, or kilocalories (1000 calories). Carbohydrates and proteins contain about 4.5 to 5 kcal/g, and fat contains about 9 kcal/g. Metabolic rate is estimated as the basal metabolic rate (BMR) in endothermic animals at rest and as the standard metabolic rate (SMR) in ectotherms. Human males have a BMR of 1600 to 1800 kcal/day, and human females have a BMR of 1300 to 1500 kcal/day. Even with insulation, endothermal animals require extensive amounts of energy to maintain a constant body temperature. An ectotherm such as an alligator has an SMR of 60 kcal/day. Energy Requirements Related to Body Size Smaller endothermic animals have a greater surface area for their mass than larger ones (Figure 33.4). Therefore, smaller animals lose heat at a faster rate than larger animals and require more energy to maintain a constant internal temperature. This results in a smaller endothermic animal having a higher BMR, per body weight, than a larger endothermic animal. Q: Metabolism produces waste energy in the form of heat, which helps what type of animal conserve and maintain heat at a relatively constant body temperature? A:
OPTIONS:
- lizard
- cold-blooded (ectotherm)
- amphibian
- warm-blooded (endotherm)

Answer: warm-blooded (endotherm)
