Remember that a controlled variable is a variable that stays the same thoughout the experiment.

it wouldn't be a. because two different wires were used

the final length of the wax would be your dependent variable, so it wouldn't be c.

the thermal conductivity is the independent variable so it isn't d.

the original length of the wax was the same for both.

So B is your answer.

9. Describe one way you use scientific "problem solving" thinking skills in
Olin [163]

Answer:

<u><em>Everyone needs critical thinking</em></u>

We all encounter opportunities in our daily lives to engage problems and decisions using strong critical thinking. Everyone needs to think ahead, to plan and to problem solve. In fact, strong thinking is the common denominator of success throughout the world.  It’s easy to find examples of  critical thinking skills being applied, everyday, in everyday life.

<u><em></em></u>

<u><em>Here are fifteen positive examples of critical thinking</em></u>:

A person trying to interpret an angry friend’s needs, expressed through a rush of emotion and snide comments, to give that friend some help and support.

A manager trying to be as objective as possible when settling a dispute by summarizing the alternatives, with fairness to all sides to a disagreement.

A team of scientists working with great precision through a complex experiment in an effort to gather and analyze data.

A creative writer organizing ideas for the plot of a story and attending to the complex motivations and personalities of the fictional characters.

A person running a small business trying to anticipate the possible economic and human consequences of various ways to increase sales or reduce costs.

A master sergeant and a captain working out the tactical plans for a dangerous military mission.

A soccer coach working during halftime on new tactics for attacking the weaknesses of the other team when the match resumes.

A student confidently and correctly explaining exactly to his or her peers the methodology used to reach a particular conclusion, or why and how a certain methodology or standard of proof was applied.

An educator using clever questioning to guide a student to new insights.

Police detectives, crime scene analysts, lawyers, judges, and juries systematically investigating, interrogating, examining, and evaluating the evidence as they seek justice.

A policy analyst reviewing alternative drafts of product safety legislation while determining how to frame the law to benefit the most people at the least cost.

An applicant preparing for a job interview thinking about how to explain his or her particular skills and experiences in a way that will be relevant and of value to the prospective employer.

Parents anticipating the costs of sending their young child to college, analyzing the family’s projected income, and budgeting projected household expenses in an effort to put aside some money for that child’s future education.

An ecosystem has 150 organisms of 15 different species. What is the biodiversity index of this ecosystem?
iren2701 [21]

Answer:

0.1

Explanation:

To calculate this, scientists use a formula called the biodiversity index in order to describe how much are the species of a given area diverse. It is calculated by taking the number of species in the area and divided by the total number of individuals in that area. This gives us the biodiversity index.

In this example, there are 15 species in an area and we divide that by 150 organisms to get a 0.1 biodiversity index.

Use this information to answer questions 6 - 11. Your original population of
grigory [225]

Answer:

1. How did the tidal wave  affect the predicted frequencies of the alleles in the population?

No changes

2. What is the frequency of the recessive allele?

q= 0.6

Explanation:

If we assume that all individuals were equally likely to be wiped out, that means the frequency/ratio of the gene and genotype of the population will not change. The tidal wave killing 100 out of 200, so it simply makes the population become half of it used to be.  

If the population at equilibrium, we can use the Hardy-Weinberg formula to find out the expected frequency of the dominant and recessive alleles. There are 36 homozygous recessives out of 100, so the frequency of the recessive allele will be:

q^2 = 36/100

q= √36/100= 6/10= 0.6
