Answer the following question given this paragraph: Mammals generate heat mainly by keeping their metabolic rate high. The cells of mammals have many more mitochondria than the cells of other animals. The extra mitochondria generate enough energy to keep the rate of metabolism high. Mammals can also generate little bursts of heat by shivering. Shivering occurs when many muscles contract a little bit all at once. Each muscle that contracts produces a small amount of heat. Q: Mammals generate heat primarily by maintaining a high rate of what? A:
****
A: metabolism

Answer the following question given this paragraph: Heat is the transfer of thermal energy between substances. Thermal energy is the kinetic energy of moving particles of matter, measured by their temperature. Thermal energy always moves from matter with greater thermal energy to matter with less thermal energy, so it moves from warmer to cooler substances. You can see this in the Figure below . Faster-moving particles of the warmer substance bump into and transfer some of their energy to slower-moving particles of the cooler substance. Thermal energy is transferred in this way until both substances have the same thermal energy and temperature. For a visual introduction to these concepts, watch the animation "Temperature vs. Heat" at this URL:. Q: Kinetic energy of moving particles of matter, measured by their temperatures are known as: A:
OPTIONS:
- visible energy
- atmospheric energy
- solar energy
- thermal energy
thermal energy

Answer the following question given this paragraph: The spiral structure in the picture is a large organic molecule. Can you guess what it is? Here's a hint: molecules like this one determine who you are. They contain genetic information that controls your characteristics. They determine your eye color, facial features, and other physical attributes. What molecule is it?. Q: What is the distinctive shape of the molecule that contains genetic information? A:
OPTIONS:
- cube
- conical
- cylindrical
- spiral

Answer: spiral

Question: Answer the following question given this paragraph: 19.2 Population Growth and Regulation Populations with unlimited resources grow exponentiallywith an accelerating growth rate. When resources become limiting, populations follow a logistic growth curve in which population size will level off at the carrying capacity. Populations are regulated by a variety of density-dependent and density-independent factors. Life-history characteristics, such as age at first reproduction or numbers of offspring, are characteristics that evolve in populations just as anatomy or behavior can evolve over time. The model of r- and K-selection suggests that characters, and possibly suites of characters, may evolve adaptations to population stability near the carrying capacity (K-selection) or rapid population growth and collapse (r-selection). Species will exhibit adaptations somewhere on a continuum between these two extremes. Q: When resources become limiting, populations follow a logistic growth curve in which the size will level off at a point called what? A:
OPTIONS:
- believed capacity
- full capacity
- containing capacity
- carrying capacity
Answer: carrying capacity
