Chapter 2: Problem 1

The table below lists the normal ranges of various chemicals found in human blood. $$ \begin{array}{|l|l|} \hline \text { Substance } & \text { Normal Range } \\ \hline \text { total cholesterol } & 125-200 \mathrm{mg} / \mathrm{dL} \\ \hline \text { HDL cholesterol } & \text { under } 40 \mathrm{mg} / \mathrm{dL} \\ \hline \text { LDL cholesterol } & \text { under } 130 \mathrm{mg} / \mathrm{dL} \\ \hline \text { triglycerides } & \text { under } 150 \mathrm{mg} / \mathrm{dL} \\\ \hline \end{array} $$ Which of the following statements is accurate based on the table above? A. A total cholesterol level of 150 is considered normal. B. A triglyceride level of 180 is considered normal. C. An LDL cholesterol level of 110 is considered above normal. D. A triglyceride level of 100 is considered abnormal.

Short Answer

Expert verified
A total cholesterol level of 150 is considered normal.

Step by step solution

01

Identify the normal ranges from the table

From the table above, we can determine the normal ranges for each of the chemicals: - Total cholesterol: 125-200 mg/dL - HDL cholesterol: under 40 mg/dL - LDL cholesterol: under 130 mg/dL - Triglycerides: under 150 mg/dL
02

Analyze each statement

We will now analyze each statement to determine if they are accurate based on the table. A. A total cholesterol level of 150 is considered normal. This statement is accurate because 150 mg/dL is within the normal range of total cholesterol (125-200 mg/dL). B. A triglyceride level of 180 is considered normal. This statement is inaccurate because 180 mg/dL is above the normal range of triglycerides (under 150 mg/dL). C. An LDL cholesterol level of 110 is considered above normal. This statement is inaccurate because 110 mg/dL is within the normal range of LDL cholesterol (under 130 mg/dL). D. A triglyceride level of 100 is considered abnormal. This statement is inaccurate because 100 mg/dL is within the normal range of triglycerides (under 150 mg/dL). Based on the analysis, we can see that statement A is the only accurate statement.

If the equations of two lines are given by \(y=-28 x-4\) and \(y=2 x+11\), then at which of the following points do the two lines intersect? A. \(\left(-\frac{9}{2}, 2\right)\) B. \((2,15)\) C. \(\left(-\frac{1}{2}, 10\right)\) D. \((-26,7)\)

Chemicals can be classified as acidic, neutral, or basic, depending on their \(\mathrm{pH}\) measurements. \(\mathrm{A} \mathrm{pH}\) below 7 indicates that a substance is acidic, a \(\mathrm{pH}\) of 7 means that a substance is neutral, and a pH above 7 means that a substance is basic. An indicator is a chemical compound that, when added to a substance, changes color based on the \(\mathrm{pH}\) of the solution. For example, cabbage juice is an indicator that turns blue when added to a basic substance. $$ \begin{array}{|l|l|} \hline \text { Liquid } & \text { pH } \\ \hline \text { apple juice } & 3 \\ \hline \text { water } & 7 \\ \hline \text { acid rain } & 5 \\ \hline \text { ammonia } & 11 \\ \hline \end{array} $$ Based on the information and the table above, which of the following substances, if combined with cabbage juice, would cause the cabbage juice to turn blue? A. apple juice and acid rain B. water C. acid rain D. ammonia

The passage below is incomplete. For each “Select” option, choose the option that correctly completes the sentence. (For this practice test, circle your selection.) September 20, 2011 Ms. Celine Margot Chair, AIM Foundation 1235 Deer Park Road Rochester, NY Dear Ms. Margot, I was so honored to meet you last week at the AIM Foundation Benefit. When I walked in the door, I had no idea I was about to be introduced to a Phi Kappa sister: Although, I should not really have been surprised; the members of our sorority their works of charity. I was touched to hear the outreach that AIM is doing, helping poor villages in several countries have access to clean water. Clearly, your foundation has a commitment to bettering the lives of those communities who live closest to subsistence level. As we discussed that night, my company, Clear Image, has great experience helping organizations we have been at the forefront of social media and viral image marketing and during that time the clients we have had range from Fortune 500 companies to philanthropic fraternities. We produce content highlighting your activities via blogs and user collect news reports with a bearing on your organization’s goals. After we connected at the fundraiser, it occurred to me that with AIM approaching 10 whole years of community service, the time would be right for a major media push touting AIM’s accomplishments to date. We have, in fact, initiated special media events for several companies. As AIM’s 10th anniversary nears, your board of directors has probably been considering ways to make that anniversary special. To that end, I suggest we meet so that I could present some of the promotional work we have done and give you a sense of the nuances of what handle the celebration of “10 Years of AIM.” Feel free to call me at 748-555-2398 if you’d like to explore how Clear Image can make AIM more prominent in the world of philanthropy. Yours truly, Misha Ayakusi Coordinator, Philanthropy & Social Service Image Enhancement
