An environmental scientist measured the rate of enzymatic breakdown of microplastics (\tex… — ACT

An environmental scientist measured the rate of enzymatic breakdown of microplastics ( $\text{mg/L/hr}$ ) by a bacterial strain across five different incubation temperatures ( $^\circ\text{C}$ ). The results are shown in the table below:

Incubation Temperature ( $^\circ\text{C}$ )	Breakdown Rate ( $\text{mg/L/hr}$ )
10	2.0
20	5.5
30	12.0
40	8.5
50	1.0

Which of the following descriptions best characterizes the line graph that accurately translates these experimental results?

A line graph plotting Incubation Temperature ( $^\circ\text{C}$ ) on the x-axis and Breakdown Rate ( $\text{mg/L/hr}$ ) on the y-axis, where the curve rises from a point at $(10, 2.0)$ to a peak at $(30, 12.0)$ , before declining to $(50, 1.0)$ .Cevap
B
A line graph plotting Breakdown Rate ( $\text{mg/L/hr}$ ) on the x-axis and Incubation Temperature ( $^\circ\text{C}$ ) on the y-axis, where the curve moves rightward from $(2.0, 10)$ to a peak at $(12.0, 30)$ , before returning leftward to $(1.0, 50)$ .
C
A line graph plotting Incubation Temperature ( $^\circ\text{C}$ ) on the x-axis and Breakdown Rate ( $\text{mg/L/hr}$ ) on the y-axis, showing a strictly increasing linear trend from $(10, 2.0)$ up to $(50, 12.0)$ .
D
A line graph plotting Incubation Temperature ( $^\circ\text{C}$ ) on the x-axis and Breakdown Rate ( $\text{mg/L/hr}$ ) on the y-axis, where the curve decreases from a maximum at $(10, 12.0)$ down to a minimum at $(50, 1.0)$ .

Cevap

The correct line graph plots Incubation Temperature on the horizontal x-axis and Breakdown Rate on the vertical y-axis, forming a curve that increases to a peak value of 12.0 mg/L/hr at 30°C and then drops to 1.0 mg/L/hr at 50°C.

The correct graph properly places Incubation Temperature on the x-axis and Breakdown Rate on the y-axis. The data points from the table demonstrate an initial rise in rate up to 30°C (12.0 mg/L/hr), followed by a decline as temperature increases further to 50°C (1.0 mg/L/hr), which corresponds exactly to a peaked curve.

Adım Adım Çözüm

Identify axis assignments for translating tabular data to a line graph.

The independent variable (Incubation Temperature in °C) belongs on the horizontal x-axis, and the dependent variable (Breakdown Rate in mg/L/hr) belongs on the vertical y-axis.

Standard ACT scientific graphical conventions place controlled/independent variables on the x-axis and measured/dependent variables on the y-axis.

Trace the key data coordinates from the table

(x, y)

Points are

(10, 2.0)

(20, 5.5)

(30, 12.0)

(40, 8.5)

, and

(50, 1.0)

Accurate format translation requires verifying specific numeric values at each data level.

Analyze the trend of the data points.

The rate increases from 10°C to 30°C (reaching a peak of 12.0 mg/L/hr), then decreases from 30°C to 50°C.

The curve must visually reflect this unimodal (bell-shaped) trend.
