How would you set up a control tube?

Biology
1 answer:
yanalaym [24]3 years ago
5 0

When you say 'control tube' it's probably the type of control in your specific experiment, but normally a control is used to compare your experiment with the effects of having something in it and something out. So say you run an experiment in which your testing the effects of oxygen on photosynthesis, your control would be a trail with no oxygen present and testing rate of photosynthesis. You would then compare this control with the results of having oxygen present on the rate of photosynthesis.

I hope it helps!!!!!!!!!!

Good luck :)

An increase in the greenhouse effect causes an increase in___
andriy [413]

The answer is option B "temperature." Greenhouse effect is the process of trapping the suns heat in the lower atmosphere. A increase of greenhouse effect would cause surface temperatures to rise.  Which then contributes to global warming because of melting the ice bergs in cooler areas on Earth and causing waters to rise and creating storms. It's not option A because the sun gives off heat or harmful radiant waves which doesn't increase carbon dioxide levels. Wouldn't be option D because it would contribute but it wouldn't happen without a increase of temperature. It also wouldn't be option C because oxygen isn't relevant in this case.

Hope this helps.

Are fibrous proteins heavier than globular proteins in terms of molecular weight? Why?
quester [9]

Answer:

Proteins range in molecular weight from 1000 to more than 1 million daltons (Da), but the folded size of a globular protein is not necessary correlated to its molecular weight. Proteins composed of about 250 amino acids or less often have a simple, compact globular shape. Larger globular proteins are usually made up of two or more recognizable and distinct structures, termed domains or modules. These are compact, folded protein structures that are usually stable by themselves in aqueous solution. Typical domain structures consist of hydrophobic cores with hydrophilic surfaces. Individual domains often possess unique functional behaviors and often perform unique functions within the larger protein in which they are found.
