the change in gene frequencies in a population over time

Requires individuals who, due to certain characteristics, produce more surviving offspring

1. Results from microevolutionary changes in gene frequencies

2. Results in the reproduction of an organism with certain inheritable characteristics in a particular environment

Large populations

Populations have become increasingly different in their
characteristics and strong selective forces are acting on the phenotype

regulate the flow of energy and the cycling of essential elements

The number of individuals in a particular species that a region can support

1. Is exponential

2. Is sigmoidal

1. may prevent/ inhibit the actual mating process

2. may inhibit the fusion of gametes released into ponds or streams

1. courtship or mating rituals including songs and calls

2. geographic isolation

3. prevention of gamete fusion

Closely related species may live in the same community and share nesting sites. (T/F)

No two species can occupy the same niche indefinitely without competition driving one to extinction. (T/f)

Initially an insect eats a broad spectrum of microbes in its aquatic environment. A closely related insect moves in.

One insect species will specialize in eating microbes found in a specific region of the aquatic environment while the other will specialize to eat another set of microbes.

Two or more species interacting together to the benefit of both species

Two or more species interacting together to the benefit of one species and but detrimental to the other species' wellbeing

Two or more species interacting together to the benefit of one species without harming the other species

1. measures the grams of carbon fixed into organic molecules in a time period

2. increases with species diversity

Which of these factors are not key elements in the environmental challenge?

In order to adapt to environmental challenges such as temperature extremes, organisms may be adapted for

Physiological adaptations such as the production of antifreeze proteins

Wind comes off coast and drops rain on the coastal side of the mountains, and is a dry wind on other side of mountains.

1. the amount of precipitation that falls annually

2. mean annual temperature

1. energy efficiency of the product

2. the ease of disassembling and reusing or recycling the various components

During the design process impacts on which of these areas must be considered?

ISO certification verifies that a product or service meets the environmental requirements of the International Organization for Standardization (T/F)

Changes in behavior to deal with environmental temperatures includes behaviors such as

1. reptiles basking on sunny rocks when cool

2. desert animals burrowing during the hottest part of the day

3. hibernation of some bear species during the winter

During the design and manufacturing process, the impact of a product on various segments of the environment must be monitored (T/F)

1. reduce energy consumption during the life cycle of a product

2. Design in such a way that the product or parts of it can be reused

3. use materials that can be recycled or reused

4. rethink the product and its functions

Transpiration contributes to atmospheric humidity and daily precipitation.

1. measures the grams of carbon fixed into organic molecules in a time period

2. increases with species diversity
