Hello!

An initial observation is the first thing a scientist notices about a topic before conducting the experiment. We can see that it is the first thing in the paragraph in this case, that dandelions grow as unwanted weeds in many lawns.

The hypothesis is the guess about the result of an experiment made before the experiment is conducted. In this case, it is that a weed killer (Killimal) would kill all the dandelions while leaving the grass healthy. This is not specifically a guess made by the scientist, but more like a prediction he wanted to verify.

An independent variable is the variable being changed in the experiment by the scientist. Here, it is whether Killimal was sprayed or not.

The dependent variable is the variable being measured, and the one being affected by the independent variable. His observation would be whether the grass and dandelions would be killed. This is because the weed killer would be directly affecting whether or not these would be killed.

The control variables are ones which are kept the same in the experiment as to not interfere with the final results. In this case, it would be the density of dandelions, the amount of sunlight, and the amount the plants were watered. These were kept exactly the same, as they could've affected the dependent variable if changed.

The control group was the one that is not impacted by the independent variable. The control group makes sure that it actually is the independent variable affecting the dependent, and it isn't some outside unknown variable. This would be the plot without the Killimal.

The experimental group is the one being experimented on from the independent variable. This would be the plot with the Killimal.

Hope this helps!

PLS HELP ASAP If an animal cell wasn't in an isotonic solution, wouldn't active transport be able to balance the cell's volume?
ohaa [14]

Answer:

Animal cells tend to do best in an isotonic environment, plant cells tend to do best in

a hypotonic environment. This is demonstrated in the attached PDF.

Explanation:

A cell that does not have a rigid cell wall, such as a red blood cell, will swell and lyse (burst)  when placed in a hypotonic solution, a process called cytolysis. Cells with a cell wall will swell when placed in a hypotonic solution, but once the cell is turgid (firm), the tough cell wall prevents any more water from entering the cell. When placed in a hypertonic solution, a cell without a cell wall will lose water to the environment, shrivel, and probably die. In a hypertonic solution, a cell with a cell wall will lose water too. The plasma membrane pulls away from the cell wall as it shrivels, a process called plasmolysis.

I hope this helps. If not I am really sorry!

True or false: male older adults are abused at a higher rate than are women.
8090 [49]
<span>The answer False. Male older adults are not abused at a higher rate than women.

Much gender-based violence or abuse is directed towards women. This term is treated on the war against women, but a war in gender violence is a man's issue.</span>
