Answer:
wastewater and fertilizer runoff
Step-by-step explanation:
Factors such as temperature, pH electrochemical (redox) potential, and the transparency of air and water can affect the chemical and physical characteristics of ecological systems. This are as a result of activities like climate change, water contamination, and changes in water runoff.
Wastewater and fertilizer runoff causes low amount of dissolved oxygen in water, which affect biological communities and cycling thereby resulting in chemical and physical states changes.
Answer: (-1, -7)
Mhmmmmmmmm
Answer: 84/3
Step-by-step explanation:
From the table, the speed of Corinne is given by

From the graph, the speed of Aretha is given by

The distance from the starting point of Corinne at any time t is given by D = 0.125t while the distance from the starting point of Aretha at any time t is given by D = 3.5 + 0.1t
Let t be the number of minutes after the start of the race when Corinne catchs Aretha, then
0.125t = 3.5 + 0.1t
0.025t = 3.5
t = 3.5 / 0.025 = 140
Therefore, the number of <span>minutes after the start of the race that Corinne will catch Aretha</span> is 140 minutes.
Out of the three options the first one is the right answer with the given numbers <span />
