Question

always graph time on the horizontal (x) axis. label your axes
problem 1: a patient’s body temperature was recorded over a 24 - hour period; the temperature at each hour is listed in the table below. graph the data in the space provided and state whether it indicates negative or positive feedback.

time	temp, °f
3 am	98.10
6 am	98.40
9 am	98.90
12 pm	98.70
3 pm	98.50
6 pm	98.60
9 pm	98.80

type of feedback

problem 2: a man with heart disease has his blood pressure monitored closely.

time	bp mm hg
8 am	190
9 am	170
10 am	150
11 am	130
12 noon	110
1 pm	70

type of feedback

Explanation:

Step1: Understand negative and positive feedback

Negative feedback tends to maintain a stable state, while positive feedback moves a system away from its normal state.

Step2: Analyze Problem 1 data

The body - temperature data shows values fluctuating around a relatively stable range (around 98°F). This indicates an attempt to maintain a stable internal temperature, which is characteristic of negative feedback.

Step3: Analyze Problem 2 data

The blood - pressure data shows a continuous decrease over time. In a healthy regulatory system, blood pressure is maintained within a certain range. The continuous decrease is moving the system further away from the normal blood - pressure range, which is characteristic of positive feedback.

Answer:

Problem 1: Negative feedback
Problem 2: Positive feedback
