Hello!! Schools that use a no-tolerance policy are followed by consequences. My school has no-tolerance policies for drugs, alcohol, bullying, etc. If you are caught with any of these, then you will suspended or expelled, depending on the seriousness of the charge. Basically, if schools have these policies, it will be followed by a serious consequence given by the principal/teacher. I hope I have helped!! Let me know if you have any more questions. Have a great day. :)
I think it is natural selection. genetic variation also could be a factor for physical variation over the years.
Medical diagnosis is the process of determining which disease or condition explains a person's symptoms and signs.It basically enables the doctor understand what disease is the patient going through.
Diagnosis is often challenging, because many signs and symptoms are nonspecific and different diseases also have them.
For example, redness of the skin is a sign of many disorders and thus does not tell the healthcare professional what is wrong.
