When writing a school paper, what are the best ways to ensure I have correct grammar, spelling, and punctuation?
When writing a paper, or anything really, it is imperative that the paper be well written. One way to ensure that the paper is well written is to write it up ahead of time and a day later, revise the paper yourself (and use spellcheck on the computer, but I strongly advise that you not just rely on that as it will not catch 100% of mistakes). When you look at your paper with fresh eyes the next day, you may catch mistakes you missed before. In addition, you could ask a friend or parent to provide feedback on the paper for you. This is a great way to get outside opinions and can often lead to a better paper! A great resource to take advantage of while at school is a peer- tutor or your school's writing center. Peer- tutors are often free and if you schedule a session with them, they are beyond helpful. The writing center is a great place to go to when you are looking for help with anything in regards to a paper. Sometimes, even the teacher you are writing the paper for may sit down with you and review your paper if you ask ahead of time to schedule a time to meet.
What causes mental illness?
While this is a rather broad question, and there are many potential answers, I will talk about two. One answer is that in terms of heredity, the mental illness may be genetic-- you may have a predisposition for it. On the other hand, mental illness is caused by a lack of certain neurotransmitters in the brain. For instance, depression is caused by a chemical imbalance in the brain--the lack of the neurotransmitter serotonin. In this case, and in most cases in regards to mental illness, medication and therapy paired together work best. An example of a medication used to treat depression is an SSRI, or selective serotonin reuptake inhibitor. This class or group of medications essentially create and recycle serotonin in the brain, which alleviates the symptoms of depression.
What are the differences between prokaryotic and eukaryotic cells?
Eukaryotic cells have a nucleus and membrane- bound organelles, unlike prokaryotic cells. Prokaryotic cells are usually smaller in size and simple, while eukaryotic cells are bigger in size and more complex. Prokaryotic cells are usually unicellular and eukaryotic cells are usually multi- cellular.
