Answer: hypothesized that the higher pH levels would increase the rate
of movement of the Artemia. The students placed the Artemia in petri dishes with 2 mm x 2
mm grids marked off on the bottom of the dishes. The students calculated how fast the Artemia
traveled in each pH (4-9) solution by counting the number of squares on the grid that the
Artemia crossed per second of timing.
The data collected from their experiment is presented below:

1. Using the grid below, create a graph based on the above data.
Explanation: yes
The three substances that cause a double displacement reaction to occur are:
(i) Ionized compounds. These are usually water.
(ii) A gas that bubbles out a solution.
(iii) A precipitate.
In double displacement reaction is where two new compounds are formed when two parts of two compounds switch places. For example; when sodium chloride combines with silver nitrate, the two new compounds formed are Sodium nitrate and silver chloride reason being sodium and silver switched places.
Glucose In the blank, they are called monosaccharides
I think it’s because you have trouble breathing
The correct answer is B. She was measuring a rate of change.
Explanation
A linear graph is a type of graph that contains a series of data represented by points joined by linear segments, which allow you to quickly check the change in the trend of the data. Therefore, inline graphs quantitative variables are usually used to see their behavior over time. According to the above, Anjuli had to use a linear graph to express the information in the graph more clearly, because the data that he was using in his graph were quantitative variables. Also, she wanted to express the respiration rate of the yeast per minute. According to the above, the correct answer is B. Ella She was measuring a rate of change.
