Answer:

B. Maintenance of homeostasis by negative feedback

Explanation:

A negative feedback loop is one where the body responds by changing the expected outcome.

So as the runner's body temperature increases, they perspire, which LOWERS their body temperature.  This means that perspiring is a response that changes the original response, as their body temperature decreases rather than continuing to increase from exertion.

Which statement summarizes the process shown in the diagram?
stellarik [79]

The best answer would be:

A. DNA is being transcribed into mRNA.

If you'd like to know why:

In the image shown, you can see the <u>BLUE </u>strands and the <u>RED </u>strand. The Blue strand is DNA and the Red strand is mRNA. What is happening in the picture is TRANSCRIPTION. It is the process of making an RNA copy of the DNA strand to create proteins based on the DNA strand.

The <u>GREEN</u> blob is most likely RNA polymerase. Its job is to synthesize or make a complementary RNA strand of the DNA by assembling nucleotides to form an RNA strand based on the DNA template.

A patient's HDL, LDL, and triglyceride levels are 62, 77, and 60, respectively. What is the patient's total cholesterol score? S
Len [333]

Answer:

Total cholesterol score is 199

199 is high cholesterol score especially as it very close to 200. The patient should adopt diets that do not include high cholesterol food

Explanation:

a. Firstly, we want to calculate the patient’s total cholesterol score.

To get this, we use a mathematical approach.

Mathematically;

the total cholesterol score = HDL + TDL + Triglyceride = 62 + 77 + 60 = 199

The patient’s total cholesterol score is 199

b. As a doctor, I will advice the patient on the status of these measurements. Using the scale of cholesterol level, a measurement of total cholesterol = 200 represents a high cholesterol level. Since 199 is very close to 200, the patient is at a risk of high cholesterol levels and thus needs a dietary change.
