The error bars also prove this because they do not overlap at all meaning that this experiment could not have gone any other way.  The data graphed shows that on average 7.1 of the 10 isopods preferred to stay in the moist area. The reason for this is that over half of the thousands of isopod species live in the ocean or in large bodies of water.  Some of the rest live in moist areas of backyards. They live there because isopods have gills, meaning that they could dry up and die if not in a moist area. This means that isopods' natural habitats are often moist or wet. This explains why the isopods looked less stressed and preferred to go to the moist side of the choice chamber. ]]> 2022-09-01 16:44:56 UTC https://padlet.com/lisle202/chshnawbqxuyzoog/wish/2279578862 ag26151 https://padlet.com/lisle202/chshnawbqxuyzoog/wish/2284990181

This is also why the isopods dug into the dirt and hid in it.   This explains why the isopods looked less stressed and preferred to go to the textured side of the choice chamber. ]]> 2022-09-06 16:55:20 UTC https://padlet.com/lisle202/chshnawbqxuyzoog/wish/2285010418 ag26151 https://padlet.com/lisle202/chshnawbqxuyzoog/wish/2285011624 2022-09-06 16:56:05 UTC https://padlet.com/lisle202/chshnawbqxuyzoog/wish/2285011624 ag26151 https://padlet.com/lisle202/chshnawbqxuyzoog/wish/2309177637 How does the nitrate concentration affect the growth of duckweed?]]> 2022-09-22 17:11:58 UTC https://padlet.com/lisle202/chshnawbqxuyzoog/wish/2309177637 ag26151 https://padlet.com/lisle202/chshnawbqxuyzoog/wish/2309181753 N(o) - The nitrate will not affect the growth of the duckweed.

The data recorded on the data chart that was collected across the 10 days of the experiment show that the nitrate levels increase the duckweed's growth.  This is because nitrates are nutrients for the duckweed meaning increase in nitrate levels will cause duckweed to grow faster because it supplies the plant with more nourishment for the plant. Although the error bars for 0mL nitrate and 1.5mL nitrate do not overlap, showing that if the experiment was to be repeated, the claim would not change, because the graph shows logistic growth, if there was too much nitrate the duckweed would reach carrying capacity and die out. ]]> 2022-10-05 16:22:02 UTC https://padlet.com/lisle202/chshnawbqxuyzoog/wish/2327904245 ag26151 https://padlet.com/lisle202/chshnawbqxuyzoog/wish/2409539386 2022-12-05 17:50:02 UTC https://padlet.com/lisle202/chshnawbqxuyzoog/wish/2409539386 ag26151 https://padlet.com/lisle202/chshnawbqxuyzoog/wish/2409541662 Does the amount of light affect the rate of photosynthesis of a plant? ]]> 2022-12-05 17:51:40 UTC https://padlet.com/lisle202/chshnawbqxuyzoog/wish/2409541662 ag26151 https://padlet.com/lisle202/chshnawbqxuyzoog/wish/2409544671 N- The amount of light has no effect on the rate of photosynthesis of a plant.

This is all because when the plants did not have any access to light they could not create any oxygen inside the discs to rise to the top of the carbon dioxide water, while the full-light plants had a lot of light to use to photosynthesize and create oxygen, allowing those discs to float to the top faster than the partial light discs. ]]> 2022-12-05 18:10:46 UTC https://padlet.com/lisle202/chshnawbqxuyzoog/wish/2409568549 ag26151 https://padlet.com/lisle202/chshnawbqxuyzoog/wish/2470501937 How does the solute concentration affect the water movement in potato cells?]]> 2023-02-06 17:46:34 UTC https://padlet.com/lisle202/chshnawbqxuyzoog/wish/2470501937 ag26151 https://padlet.com/lisle202/chshnawbqxuyzoog/wish/2470504820 Null-  Solute concentration does not affect the water movement in potato cells

This is because the movement of water across the potato's cell membrane depends on its surroundings, meaning that when there was a lower concentration of solute outside the cell the mass of the potato gets bigger, but when there was a higher solute concentration outside the potato cell the mass of the potato got smaller.  ]]> 2023-02-07 18:18:43 UTC https://padlet.com/lisle202/chshnawbqxuyzoog/wish/2472250746 ag26151 https://padlet.com/lisle202/chshnawbqxuyzoog/wish/2507343144 How long does each phase of mitosis take in an onion root tip?

As recorded in the data 490 of the 887 cells were in interphase. The reason for this is that interphase is the part of the cell cycle where the cell prepares for division. This is where the cell's chromosomes are replicated. But, it is important that there are no mistakes in the new chromosomes so, there are checkpoints used to get rid of cells that are messed up or replicated incorrectly. So, because of the two checkpoints that avoid mistakes, the DNA synthesis, and the cell growth that has to occur in interphase, it is the longest stage of mitosis. ]]> 2023-03-07 18:17:30 UTC https://padlet.com/lisle202/chshnawbqxuyzoog/wish/2507350781
