This figure is a graph. The y-axis is labeled "reaction rate," while the x-axis is labeled "PH." The x-axis ranges from 0 to 14. The plot line is U-shaped, beginning approximately three quarters of the way up the y-axis and gradually dipping down to its low point at a PH of 6. The plot line then gradually rises again to its highest point at a PH of 12. It then dips back down to about three quarters of the way up the y-axis at a PH of 14.

Based on the graph, this enzyme is minimally active between pH 5-7 works optimally between pH 5-7 is minimally between pH 0-3 works optimally between pH 0-3

the most common type of reef is the fringing reef. this type of reef grows seaward directly from the shore. they form borders along the shoreline and surrounding islands.

airlines i think? or a cruise boat? does this work out for u? ?

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
