It has two strands
Hope this helped :))
<span>Atherosclerosis is a common cause, because there is a lack of blood flow in the person's body, and this can cause a male to be impotent.
Diabetes is also a common cause because once again it causes less blood flow.
In a younger man, a cause could be anxiety. This is because nervousness and being anxious can lessen blood flow.
If you have choices, I suggest choosing one that has to do with less blood flow happening, which that is the main cause.
I hope that this could possibly help you with your studies, and have an amazing day. If you have any more questions, send me a pm. </span>
<span>s that a single on off switch can control the whole cluster of functionally related genes; these genes are coordinately controlled (ex: when Ecoli must make tryptophan for itself because the nutrient medium lacks this amino acid all the enzymes for the metabolic pathway are synthesized at one time)</span>
Answer:
It would certainly make a difference.
Explanation:
The mass of a planet determines how thick the planets atmosphere would be, if it can even sustain an atmosphere. If all the masses are the same, all of the large planets would not be able to sustain life, while all of the smaller, denser planets still have a chance.
The mass of a planet also affects it’s gravitational pull. If all of the planets had the same mass, they would all have the same gravitational pull, meaning that they would all attract the same amount of asteroids, meteors, and other spacial objects.
Overall, the simulation would certainly be different, for many, many reasons. The above are only two, and if you would like more, just add a comment and I can give you more.
Stimulus: You get an injury.
