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 first argument Wegener put forward in support of his theory was that the continents seemed to fit together like the pieces of a jigsaw puzzle. This relationship is apparent from a map, but the exactness of the match improves if the underwater continental shelves are compared. The true edges of South America and Africa, for example, fit together to a high degree of precision, allowing for millions of years of erosion.
Wegener's second argument was more complex. He traveled the world and charted the locations and orientation of glacial till deposits. These deposits are the alluvial remnant of a glacier's progress across the landscape, and they remain long after the glacier has melted away. By plotting out the latitudes of ancient till deposits, Wegener was able to demonstrate that, for his evidence to be consistent with unmoving continents, much of the world would have had to be covered in ice sheets in the relatively recent past, even in the tropics. He argued that this was evidence that the tropical continents had once been at higher latitudes.
On a PWC, the lanyard or the short cord that fastens and
secures rigging, is attached to the ignition safety switch and the operator's
wrist or life jacket.
The automatic cut-off lanyard stops the engine when the
operator falls overboard, or out of the powerboat, or is otherwise thrown from
the proper operating position.
I am so sorry but I don’t know the answer, I just needed the points to ask a question myself
Answer:
Hiya there!
Explanation:
The difference between plant cells and animal cells is that plant cells are surrounded by a cell wall wile animal cells are not. The existence of the cell wall is used for photosynthesis of plants because it is in the cell wall where the chloroplast is located. Plant cells do not have lysosomes which has an important function for waste disposal of animal cell.
