Answer:
The independent variable in the experiment is A. the jar covers.
Explanation:
The independent variable in an experiment represents the thing that the person conducting the experiment changes or alters. One group in the experiment had covers (this represents the experimental group) and the other group had no cover (this represents the control group which was not exposed to the independent variable). Since the only thing that Redi changed between the two groups was whether or not the jars were covered, this represents the independent variable.
The number of jars and the contents of the jars were constant in both experiments, and the number of maggots on the meat is the dependent variable (the result of changing the independent variable).
Hope this helps!
Given what we know, we can confirm that sunlight is white light, when it shines on a red object the red wavelength is reflected. The other colors are absorbed, so the only thing you see is the red light reflected back.
<h3>What is white light?</h3>
We use "white light" as a term to describe the combination of all colors of light in the spectrum. The sun emits all colors of light, when this light hits an object, most of the colors are absorbed. The color that does not get absorbed is reflected back and causes us to perceive the object in that color.
Therefore, we can confirm that sunlight is white light, when it shines on a red object the red wavelength is reflected. The other colors are absorbed, so the only thing you see is the red light reflected back.

The correct answer is ocean
The water that is naturally occurring in the nature expect the seawater, water in the ocean, backish water is freshwater.
The least likely fresh water reservoir is ocean water, which is salty in nature. This has high concentration of dissolved salts in it.
This water cannot be used as potable water employed for the commercial and drinking purposes.
Answer:
The root hair cells have carrier proteins in their cell membranes. These pick up the mineral ions and move them across the membrane into the cell against the concentration gradient . ... Because active transport moves ions against the concentration gradient into the root hair cells, energy is needed.
