Which factor distinguishes the experimental group from the control group

A control group is sort of the normal group. The group you aren't changing or messing with. It is to show what the species/experiment acts like on its own in response to something without you having to change it at all. 

With an experimental group, you are changing something about the subject before putting it in the conditions it will need to respond to. 

I don't entirely understand, but I know the control group is constant, unchanging. It sort of helps with distinguishing things. I have examples of experiments if that will help you understand what a control group is to answer the question. I also have a The Death Cure example if you have seen or read the book. I hope you do not fail this assignment, but even if I did not answer with an answer you were looking for, it could have helped you answer the question on your own. 

I saw somewhere a similar question, though I was given the answer choices. If this is the answer you are looking for: variable(s).

Control groups don't use variables because you aren't changing them.

gogolik [260]

Answer:

The correct answer is 3: "<em>High levels of Ca2+ are expected to be found </em><em>within the sarcoplasmic reticulum</em>".

Explanation:

Muscular contraction is a highly regulated process that depends on free calcium concentration in the cytoplasm. Amounts of cytoplasmic calcium are regulated by <u>sarcoplasmic reticulum</u> that functions as a storage of the ion.

When a nerve impulse reaches the membrane of a muscle fiber, through acetylcholine release,  the membrane depolarizes producing the entrance of calcium from <u>extracellular space</u>. The impulse is transmitted along the membrane to the sarcoplasmic reticulum, from where calcium is released.  At this point, <em>tropomyosin is obstructing binding sites for myosin on the thin filament</em>. The calcium channel in the sarcoplasmic reticulum controls the ion release, that activates and regulates muscle contraction, by increasing its cytoplasmic levels. When <em>calcium binds to the troponin C</em>, <em>the troponin T alters the tropomyosin by moving it and then unblocks the binding sites,</em> making possible the formation of <em>cross-bridges between actin and myosin filaments.</em> When myosin binds to the uncovered actin-binding sites, ATP is transformed into ADP and inorganic phosphate.

Z-bands are then pulled toward each other, thus shortening the sarcomere and the I-band, and producing muscle fiber contraction.

Why is pollution so widespread
Pepsi [2]

Answer:

Land can become polluted by household garbage and by industrial waste. In 2014, Americans produced about 258 million tons of solid waste, according to the U.S. Environmental Protection Agency. A little over half of the waste — 136 million tons— was gathered in landfills. Only about 34% was recycled or composted.

Hope this helps and I hope its correct.

Explain the processes that take place in the stroma including the reactants going in and the products produced from these proces
poizon [28]

Stroma, in a biological explanation, the fluid in between grana, where carbohydrate formation reactions occur in the chloroplast of plant cells photosynthesizing.

Explanation:

Part A

 In the bright daylight, the Calvin cycle happens indoors in the stroma. throughout the Calvin cycle, the results  ATP and NADPH are conventional convert molecules of carbonic acid gas into high-energy sugars.

Part B

In the darkness, the Calvin cycle conjointly occurs within the stroma. through the Calvin cycle, the products ATP and NADPH are used to change molecules of CO2 into high-energy sugars.

Part C

There will be a decrease in the products ATP and NADPH if the plants are unbroken within the dark for a protracted time and also the Calvin cycle can't be sustained.
