Order the steps of the experiment below according to the scientific method. Question 7 options:

Paul noticed that sugar dissolved almost instantly when added to hot tea.

Paul decided to redo his experiment at several different temperatures.

Paul compared the graphs of cold water dissolving substances to the graphs of hot water dissolving substance.

Paul thought that the higher the temperature of water the faster it dissolved materials.

Paul tried dissolving several different substances in both cold and hot water, timing how long it took to dissolve each substance.

Paul reported that for all substances the hot water dissolved it faster.

Paul calculated the average time to dissolve each substance in each temperature.

i believe your answer would be c.. : )

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

answer-

the statement that f(x) = |x+a| + b has exactly one x-intercept is sometimes correct.

solution-

it solely depends on b, whether the function will have one or two or zero x intercept.

this plot of the given function, f(x) = |x+a| + b will be the basic absolute value graph i.e v shape, with vertex translated to (-a, b), instead of origin.

1-   if b is zero, the graph will have exactly one x-intercept, at x= -a

2- if b is positive, the whole graph will be above the x-axis, hence it will have no x-intercepts.

3- if b is negative, the graph will be below the x-axis, hence it will have two x-intercepts.

∴ the statement is sometimes true.
