The correct answer is: c. An operon is a region of DNA that codes for a series of functionally related genes under the control of the same promoter.

Operons contain cluster of genes that are transcribed together into mRNA or are not expressed at all. Formed mRNA undergos splicing to create monocistronic mRNAs so that can be translated separately. Operons are more often found in prokaryotic cells but it can appear in eukaryotic cells and in viruses.

Which pair of terms concerning the osmotic effect of a solution on red blood cells is mismatched?
QveST [7]
Even though there are no choices given in this particular question, the principle of osmosis is very easy to understand. 

When we talk about osmosis, we are referring to the movement of water from a low concentration to a higher concentration. This is different from diffusion, which talks specifically about the movement of <em>solutes</em> in the solution (from a higher concentration to a lower concentration.)

When an RBC is placed inside a <em>hypertonic </em>solution, the water inside the RBC will go out thereby shrinking the RBC.

Inside an <em>isotonic</em> solution, the RBC will remain the same because the concentrations are equal.

Inside a <em>hypotonic</em> solution, the RBC will lyse or explode because water will move from the solution going inside the RBC.

I Also like that cheetahs can be in zoos and also can be trained, petted, and can also (rarely) have babies. Cheetahs need to be saved because they are starting to get really rare and endangered.

How is hydro electricity produced step by step explanation ​
timama [110]

Answer:

ydropower, electricity produced from generators driven by turbines that convert the potential energy of falling or fast-flowing water into mechanical energy

Explanation:

In the generation of hydroelectric power, water is collected or stored at a higher elevation and led downward through large pipes or tunnels (penstocks) to a lower elevation; the difference in these two elevations is known as the head. At the end of its passage down the pipes, the falling water causes turbines to rotate. The turbines in turn drive generators, which convert the turbines’ mechanical energy into electricity. Transformers are then used to convert the alternating voltage suitable for the generators to a higher voltage suitable for long-distance transmission. The structure that houses the turbines and generators, and into which the pipes or penstocks feed, is called the powerhouse.
