When designing your experiment, what would your experimental group and your independent variable be?

prohojiy [21]2 years ago

Depending on what you decide to create an experiment on that will vary but I can provide you some different terms to help you!

Experimental Group vs Control Group:

The Experimental Group is the group you test things on and the Control Group is the group that stays the same to help you compare data. For instance let's say you are a dentist testing a new toothpaste to see if it whitens teeth more. You have 25 people in the control group who are all using the old toothpaste. In the experimental control group you have 25 people all using the new toothpaste.

And Independent Variables vs Dependent Variables:

An Independent Variable is the variable you change in order to see how it affects the dependent variable. The Dependent Variable is what the independent variable affects. Following the toothpaste example the different types of toothpaste would be the Independent Variable because there are two and they are different. The Dependent Variable would be the number of people from each control group that have whiter teeth.

It would be this way because the amount of people that have whiter teeth is dependent on the toothpaste and how well it works

A researcher proposes a model of an enzyme-catalyzed reaction in which a reactant is converted to a product. The model is based
lions [1.4K]

Answer: The answer is B: The enzyme's active site binds to and stabilizes the transition state, which decreases the activation energy of the reaction.

Explanation: An enzyme is a biological molecule which speeds up the rate of chemical reactions in the body (reactions within cells). They are proteins.

    The transition state is the transition from substrate to product. The molecule is no longer a substrate but also not yet a product.

The enzyme is able to speed up the reaction by stabilizing the transition state. The transition state's energy is also the activation energy in terms of reaction. The activation energy is the minimum energy that is required to break some bonds of the reactants in order to turn them to products.

If you were designing a method to specifically inhibit prokaryotic transcription, but not eukaryotic transcription, interfering
kobusy [5.1K]

The correct answer is: B) recognition of the prokaryotic promoter by RNA polymerase

The similarities between prokaryotic and eukaryotic transcription are that DNA is template used for the mRNA synthesis and that this is process is facilitated by the enzyme RNA polymerase.  

One of the difference between this process in eukaryotes and in prokaryotes is the promoter region: eukaryotes contain TATA box and CAT box, while prokaryotes don’t (they have  Pribnow box that is similar to the TATA box). Promoter region in prokaryotes is always upstream to the start site, while in eukaryotes it can be downstream.

How does strip cropping slow down rainfall from removing soil?
alex41 [277]

The growing of a cultivated crop (as corn) in strips alternating with strips of a sod-forming crop (as hay) arranged to follow an approximate contour of the land and minimize erosion.

Strip cropping helps to stop soil erosion by creating natural dams for water, helping to preserve the strength of the soil. Certain layers of plants will absorb minerals and water from the soil more effectively than others. When water reaches the weaker soil that lacks the minerals needed to make it stronger, it normally washes it away. When strips of soil are strong enough to slow down water from moving through them, the weaker soil can't wash away like it normally would. Because of this, farmland stays fertile much longer.

The term strip cropping also refers to a method of dry farming sometimes used in areas including parts of the Great Plains of the United States and the Prairies of Canada. To accumulate moisture in these dry areas, cropland is periodically left fallow. Typically, the fallow and planted areas are organized in parallel long, narrow strips that are oriented normal to the prevailing winds, in order to minimize the erosion of soil from the bare fields. Strip farming helps to prevent mass erosion by having the roots of crops hold on to the soil to prevent it from being washed away.

Hope this helps  Its because its really strong soil

You have a column made of nickel-agarose matrix. your protein must have ________ to use this column for affinity chromatography.
belka [17]
<span>Negatively charged R-groups in the primary structure. This is because nickel acts as a cation, therefore you would be attracting anions, in this case it would be on the proteins that would be binding to the column. Once they bind to the matrix a was buffer of high salts can elute the proteins.</span>
