Photosynthesis removes carbon dioxide naturally—and trees are especially good at storing carbon removed from the atmosphere by photosynthesis.
There is no context so I will just explain what a constant is:
In an experiment following the scientific method, a constant is a variable that cannot be changed or is purposely not changed during the experiment.
An example would be:
If a researcher wanted to study the effects of temperature on the growth and development of garden snakes, the experimental variable for the experiment would be temperature. All other variables would need to remain consistent to avoid invalid data. The size of the cage, amount of light, food and many other variables would need to remain constant to ensure accurate results and a valid study. Those variables are constants. Some variables are not under a scientist's control, but are still considered to be constants. These constants are called universal constants and include gravity, the speed of light and electronic charge. Universal constants do affect experiments but will be constant through an experiment without being controlled by the scientist.
Answer:
The correct answer is - C. protein - Millons' test - red precipitate is formed.
Explanation:
The iodine test is the test that is used for the identification or presence of the starch in a food sample, in this test if starch present in the food then the solution of iodine and KI will turn to deep blue color. Therefore the given result is incorrect
The benedict test for confirming if glucose present in the sample, it is a mixture of sodium carbonate, sodium citrate, and copper(II) sulfate pentahydrate which starts as aqua blue in color but after adding sample and gradually heating it turns from yellow to orange as per the concentration of the glucose. Thus, it is incorrect.
The emulsion test also produces the milky precipitate or emulsion in presence of fat or lipid in the sample. so, it is incorrect.
Millon's test for protein is the test that results in the red solution or red precipitate in the presence of the protein in the sample.
Biotic-the decrease of fish can Make the bear population decrease
abiotic-A rapid change in the temperature can make the bear population decline
The density is the relation mass/volume.
Then you can modifiy the density of a material by either affecting the mass or the volume.
If you increase the volumen while keeping the mass constant, the density will decrease (because you are increasing the denominator of the fraction).
Also, you can decrease the mass while keeping the volume constant to decrease the density (because you are decreasing the numerator of the fraction).
Then the answer is decrease the mass or increase the volume, while the other is kept constant.
