What are a few things one can do to improve their paper before turning it in?
Students can consult a tutor or their school's writing resource center for peer advice. Alternatively, many professors are open to meeting to give advice before assignment due dates. Independently, I strongly recommend that students read their paper out loud to themselves. As silly as this may seem, it can help detect grammatical errors, awkward wording, and incomplete or unclear thoughts that may not be recognized simply looking over the paper. General wording such as "things", or "many more" should be expanded upon so that the idea is not so broad. A thesaurus is a great resource to use more complex words, though caution should be used. In some instances, even though a word may be similar the context could be different, and may not make sense in the context of the paper. It is a great guide, but careful thought should be used when deciding if and when to replace certain words. In formal papers, students should re-word sentences using words such as "I", "you", "we", etc, and remove any contractions. When possible, use textual evidence to support papers analyzing literature. Be sure to show examples that back up ideas. A very wise professor once taught a former class of mine that students should always "show, do not tell". Whenever possible, it is crucial to show direct examples instead of explaining the background of a story. It will make analysis much stronger. Finally, in formal papers an authoritative tone should be used. Avoid words such as "probably" or "likely" -- take a firm stance and back up the stance with sufficient evidence.
Describe the differences between the following terms: Expression Equation Inequality
Expressions are the simplest structures in math. It consists of a number (or numbers) joined by operation signs (+,-,x,/) It can be as simple as -3, or more complex such as 5x+2. In the second example, there is a variable x. Note that it does NOT include an equals sign. Equations are expressions that are joined by an equals sign. Ex: 8+2 = 10, or 2x+5=35 Inequalities are expressions that are joined by a relation symbol -- > greater than, < less than etc. 5>2
Describe the structure of the heart, and the blood flow throughout.
The heart is made up of four chambers, the atria (singular - atrium) and the ventricles. A protective sac called the pericardium protects the heart. There are two atria and two ventricles -- left and right. The atria are superior (above) the ventricles. Deoxygenated blood is received in the right atrium from the rest of the body (systemic circulation) and is pumped into the right ventricle. From there, it is is carried to the lungs via the pulmonary artery to be oxygenated. It is carried form the lungs back to the left atrium via the pulmonary veins. It is then pumped into the left ventricle which pumps it to the rest of the body via systemic circulation. It is important to understand that this occurs at the same time. the left and right heart pumps simultaneously.
