After reading about the scientific method, explain why it's important to follow the steps outlined in the scientific method care

fully. How can researchers prevent mistakes and errors in their experiments? A good answer should include the following: Importance: So that the results would be due to the specific variables tested and not due to something else So that other researchers could follow the steps and carry out the same experiments Prevent mistakes: Carefully selecting variables Following the steps outlined in the procedure Carefully and accurately measuring quantitative data

Answer:

It's important to follow the steps outlined in the scientific method carefully

so that the results would be due to the specific variables tested and not due to something else. Not only that but this also allows  other researchers to follow the steps and carry out the same experiments.

Researchers can prevent mistakes and errors in their experiments by

carefully selecting variables,  following the steps outlined in the procedure and  carefully and accurately measuring quantitative data

Answer:

hope this helps.  Cutting a gold bar in two pieces and then putting the pieces next to each other: It is a physical change but it is not reversible as original state is not achieved again. b) burning a match and then relighting it: This is a chemical change as new substances are formed.

Using at least 3 steps explain how to make a wet mount slide with an Elodea plant​
Masja [62]
Step One - Obtain a clean microscope slide.

Step Two - Place a drop of liquid on the slide. This is the “wet” part of the wet mount. The liquid used depends on the type of cell being viewed:
If examining a plant cell, tap water can be used.
If examining an animal cell, physiological saline (or contact lens solution) must be used, because if plain water is used, the cell will explode from osmotic pressure. Unlike plant cells and bacteria, animal cells have no cell wall to structurally support them.

Step Three - Obtain the specimen to be used. Some introductory biology classics for viewing include:
Skin of an onion bulb: In order to view the cells, a very thin layer of skin must be obtained. Take a single layer of onion and bend it towards the shiny side. After it snaps, pull gently, and a transparent layer of skin, similar to Scotch tape, will appear.
Elodea leaf: Elodea leaves are two cell layers thick. The cells in one layer are smaller than the cells in the other, so elodea leaves can be used to better understand a microscope's depth of field.
Cheek cells: Human epithelial cells can be obtained by gently rubbing a toothpick on the inside of the mouth, and then swirling the toothpick in the physiological saline on the slide.
Pond water: Obtaining some water from a pond makes wet mount preparation a breeze, since the water and the specimens are both included.
Hope this helps
