Activity B: Get the Gizmo ready:

• Click Reset.

• On the SIMULATION pane, make sure Ample is

selected for the amount of LAND available.

Density-dependent

limiting factors

Introduction: Population density is the number of individuals in a population per unit of area. Some limiting

factors only affect a population when its density reaches a certain level. These limiting factors are known as

density-dependent limiting factors.

Question: How does a density-dependent limiting factor affect carrying capacity?

1. Think about it: What do you think some density-dependent limiting factors might be?

2. Predict: Suppose a shopping mall is built near a rabbit warren, leaving less land available for rabbits. How

will this affect the environment's carrying capacity?

3. Experiment: Use the Gizmo to find the carrying capacity with Am

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.

the principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to test the hypothesis, and development of a conclusion that confirms, rejects, or modifies the hypothesis.

they kick it to the curb.

explanation:

that current was nasty.

bal is blood alcohol level. bac will normally be higher in a person with more body fat. so the answer to your question would be, as body fat decreases, the increasing rate of bal decreases.
