Bio1208 Midterm

What should go in a null hypothesis?

independent variable and treatments dependent variable will NOT the term "significant difference" or "significantly effect" specific reaction model organism

Transmittance

Object color. The logarithmic inverse of absorbance.

MIX DRY

Manipulate the Independent Variable on the X-axis the Dependent variable Responds on the Y-axis

How is the introduction formatted?

The section begins with broad background information and ends with narrow information about the study.

What does it mean when the p-value is greater than 0.05?

The null hypothesis is failed to be rejected. (It cannot be rejected)

How should table captions appear in a report?

centered and above the table

How should table captions appear in a report?

centered and above the table

How should figure captions appear in a report?

centered and below the figure

Independent Variable

influences or is manipulated When graphing, goes on the X-axis.

An experiment shows a p-value less than 0.05. The bar graph shows that the first two treatments have overlapping standard error bars, but the third treatment did not overlap the others. What does this mean?

The first two treatments are not significantly different from each other, but they are both significantly different from the third treatment.

Dependent Variable

responds or is measured when graphing, goes on the Y-axis.

How is the discussion section formatted?

Starts with narrow information about the study and broadens to real world applications.

Enzyme

an organic catalyst that speeds up the rate of a reaction by decreasing the activation energy.

After an experiment, data analysis shows a p-value of 0.06. What does this mean for the hypothesis and what is the next step?

Results are not significantly different to the p-value. No further statistical analysis is needed.

As absorbance increases, what happens to concentration?

Concentration increases

What is the purpose of the Methods section

to describe the procedures and materials used in the study

Specifically, in the BIOL 1208 enzyme experiment: What is the name of the ENZYME that catalyzes the reaction?

Catecholase

What does it mean when the p-value is less than 0.05?

Null hypothesis can be rejected

What should go in an alternative hypothesis?

independent variable and treatments dependent variable WILL the term "significant difference" or "significantly effect" specific reaction model organism

Specifically, in the BIOL 1208 enzyme experiment: What is the name of the SUBSTRATE being catalyzed?

Catechol

What does the Results section include?

Includes figures that visually represent data and key trends found

What does the Discussion section include?

includes a discussion about the data, limitations of the experiment, and broader impacts.

How is concentration of a solution determined?

Plugging absorbance in the (y) into the standard curve equation and solving for X (concentration).

Absorbance

Capacity of a substance to absorb light of a specific wavelength

Prediction

states in what direction the researcher thinks the experiment will go. Based on reasoning and includes a citation.

Substrate

a molecule that an enzyme interacts with

Specifically, in the BIOL 1208 enzyme experiment: What is the name of the PRODUCT formed from the reaction?

Benzoquinone
