Question:

1. Describe the properties of a strong thesis statement. 2. Using what you know about the properties of a strong thesis statement, improve the following thesis statement: "In this essay, I will talk about whether students should wear school uniforms."

Answer:

1. A strong thesis statement clearly states the author's position on the topic they are addressing. It is brief (1-2 sentences) and placed somewhere near the end of the introduction (often the conclusion of the first paragraph). A strong thesis statement is also original, focused (narrow), debatable, and specific. 2. The primary issue with the original thesis statement is that it does not choose a position. There are a wide range of possible responses for this question, but here are a few examples of strong revisions: "School uniforms save families time and money, and therefore should be mandatory in public schools." "School uniforms should not be required as they limit student expression and creativity."

Question:

1. Balance the following chemical equation. $$ H_{2} $$ + $$ O_{2} $$ = $$ H_{2}O $$ 2. What type of chemical reaction is it?

Answer:

1. $$ 2H_{2} $$ + $$ O_{2} $$ = $$ 2H_{2}O $$ To balance this chemical equation, count the number of H (hydrogen) and O (oxygen) on each side. In order for the chemical equation to be balanced, there must be an equal number of H and O on both the left and right side of the equation. As originally written, there are two H and two O on the left side of the equation, and two H and one O on the right side. Therefore, in order to balance the equation, there must be an additional O on the right side of the equation. Adding a 2 in front of the $$ H_{2}O $$ on the right side of the equation will balance the O. However, doing so will unbalance the H, as there will be four H on the right and 2 H on the left. Adding a 2 in front of the $$ H_{2} $$ on the left side will balance the equation. 2. This reaction follows the formula A+B yields AB. Two reactants form one product. Therefore, it is a synthesis reaction.

Question:

How do the processes and outcomes of mitosis and meiosis differ?

Answer:

Mitosis and meiosis are both forms of cell division. Mitosis forms diploid (2n) daughter cells and is used for growth, repair, and asexual reproduction. Mitosis consists of one round of cell division, in which sister chromatids separate. The diploid daughter cells are genetically identical to the parent cell. On the contrary, meiosis forms haploid (n) gametes (e.g. sperm and egg) that are used for sexual reproduction. Meiosis consists of two rounds of cell devision, without DNA replication between them (Meiosis I and Meiosis II). Homologous chromosomes segregate in Meiosis I, and sister chromatids segregate in Meiosis II. The haploid gametes are genetically different from the parent cell and each other, due to both crossing over in prophase I and separation of homologous chromosomes in Meiosis I.
