Question 1

Applied researchers conduct their work to:

Accepted Answer

Applied researchers conduct their work to solve specific practical problems.

Question 2

When conducting descriptive research, a scientist primarily uses:

Accepted Answer

Descriptive research is primarily done through observational data collection methods such as surveys or naturalistic observation. Control data and experiments are usually associated with experimental research, while data is too broad of a term to be specific to one research method.

Question 3

Temperatures in all animal species are regulated primarily by behavioral mechanisms.

Accepted Answer

homeostatic

Question 4

If a biologist searches for explanations about natural phenomena solely to satisfy his or her curiosity and advance our collective knowledge of living systems, then, this researcher is a(n):

Accepted Answer

A basic researcher is someone who searches for explanations solely to satisfy their curiosity and advance our collective knowledge of living systems.

Question 5

What are the contributions of Beadle, Tatum, Watson, and Crick to biology? What techniques did they use to revolutionize biological science?

Accepted Answer

The answer of What are the contributions of Beadle, Tatum,...

Question 6

Why do scientists use model organisms?

Accepted Answer

The answer of Why do scientists use model organisms?...

Question 7

An approach in which scientists make observations about the natural world, develop tentative explanations about what they observe, and then test those explanations by collecting more information is referred to as ____.

Accepted Answer

The approach described is commonly known as the scientific method, which involves making observations, formulating a hypothesis or explanation for the observations, testing the hypothesis through additional observations or experiments, and then refining or rejecting the hypothesis based on the results of those tests. It is a fundamental process in the practice of science.

Question 8

If a researcher collects basic information on biological structures or the details of biological processes, then the researcher's approach is considered to be:

Accepted Answer

Descriptive science involves collecting basic observations or information about biological structures or processes. It is a valid approach within the larger framework of scientific inquiry.

Question 9

You are at a stage in your research in which you must design an experiment to test your hypothesis.What factors must you include to insure that your experimental data is good valid data?

Accepted Answer

The answer of You are at a stage in your...

Question 10

Populations can be described in terms of their diversity and stability

Accepted Answer

Communities

Question 11

Explain the need for a null hypothesis, especially in ecology and evolution.What does a null hypothesis accomplish?

Accepted Answer

The answer of Explain the need for a null hypothesis,...

Question 12

Hypotheses that are falsifiable fall within the realm of:

Accepted Answer

Falsifiability is a key aspect of the scientific method. In science, hypotheses are proposed and then tested through experimentation or observation. If the results of these tests do not support the hypothesis, it may be rejected or modified. This process allows scientific knowledge to be continually refined and improved upon.

Question 13

Protists do not constitute a kingdom because they do not share a unique common ancestor.

Accepted Answer

Protists are a diverse group of organisms that do not share a unique common ancestor, making them a paraphyletic group rather than a kingdom defined by shared ancestry.

Question 14

Scientific theories are of fundamental importance in science.Explain the difference between the term "theory" as employed in science versus "theory" as employed in everyday language.

Accepted Answer

The answer of Scientific theories are of fundamental importance in...

Question 15

The example of an adaptation provided by the rock pocket mice illustrates the observation that genetic differences often develop between individuals.

Accepted Answer

populations

Question 16

When a student manipulates a system under study, he or she is collecting:

Accepted Answer

Manipulating a system under study refers to conducting an experiment, which involves collecting experimental data. Empirical data may be collected through observation, while observational data is collected through systematically recording one's observations. Data refers to any kind of information collected, while facts refer to information that is confirmed to be true. Therefore, the best choice is experimental data as it specifically refers to data collected through manipulation of a system under study.

Question 17

Although Darwin and Wallace understood the central importance of heritability among organisms to the process of evolution, they could not explain how new variations arose or how they were passed to the next generation.

Accepted Answer

variability

Question 18

Much of our understanding of how large organisms respond to environmental variation is based on using model species.

Accepted Answer

Using model species allows researchers to control and manipulate experimental conditions more easily, making it possible to investigate environmental responses in great detail. This information can then be applied to other, more ecologically important, species.

Question 19

If the results of a set of experiments match predictions, the hypothesis must be rejected or revised.

Accepted Answer

do not match

Question 20

You are studying an ecosystem in your campus; after a solid base of carefully observed and described facts, your next step would be to:

Accepted Answer

After gathering and describing facts, the next logical step in the scientific method is to formulate a hypothesis, which is a testable explanation for the observations.
