Biology Ch. 1 Review

How have computer models expanded biological research?

• They help scientists design better experiments

• They stimulate complex biological systems that cannot be studied directly.

• They give scientists the ability to observe molecules directly.

• They allow the use of human experimental subjects.

The study and manipulation of DNA on the molecular level is known as

• biochemistry

• genomics

• molecular genetics

• evolution

The process shown uses and applies biological processes. This process is an example of

• biotechnology

• genomics

• imaging technology

• transgenic organisms

Exploring how indoor air pollutants lead to respiratory problems is an example of using biology to

• develop biotechnology.

• monitor global change.

• improve human health.

• make ethical decisions.

The various parts of Earth's biospher are connected and

• similar.

• nonliving.

• diverse.

• aquatic.

A group of interacting, interrelated, or interdependent elements forming a complex whole.

• Structure

• System

• Function

• Organ System

If you were investigating the effect of a neurotoxin on fish behavior, the fish behavior is what type of variable?

• control

• dependent

• independent

• constant

All the chemical processes used to build up or break down materials are called an organism's

• metabolism.

• homeostasis.

• adaptations.

• stimuli.

What is the name given for genetic changes in living things over time?

• adaptation

• homeostasis

• evolution

• negative feedback

When our body temperature gets too high, we sweat which in turn cools us down causing our body temperature to go down. This is an example of

• evolution

• negative feedback

• positive feedback

• adaptation
