Answer:
Infrared light is used by electrical heaters, cookers for cooking food, and by infrared cameras which detect people in the dark. Infrared light has frequencies which are absorbed by some chemical bonds. ... This makes infrared light useful for electrical heaters and for cooking food. All objects emit infrared light.
Answer:
Explanation:
Accuracy is defined is as the ability to perfectly repeat results in an experiment. It is simply reproducing the same set of result with little to no altercation.
Precision is nearness of the result to the true value.
(a) Checking for consistency in the weight of chocolate chip cookies: 17.27 g, 13.05 g, 19.46 g, 16.92 g
The result above is neither accurate nor precise. We can see a lot of inconsistencies in the readings shown and no repeatability whatsoever.
(b) Testing the volume of a batch of 25- mL pipettes: 27.02mL, 26.99 mL, 26.97 mL, 27.01 mL
The results here are accurate but not precise. They are a little bit off the 25mL mark but the experiment was able to reproduce nearly the same result.
(c)Determining the purity of gold: 99.9999%, 99.9998%, 99.9999%
This result is both precise and accurate. Pure Gold should be 100% and our values are very close. The experiment also was able to generate very accurate results.
<u>Answer:</u>
The Calvin cycle converts ATP and NADPH to "convert CO2 to sugar".
<u>Explanation:</u>
When carbon dioxide reaches inside the leaf through pores called stomata in plants and spreads to the chloroplast stroma, it act as the location of Calvin cycle reactions where sugar is naturally produced.The light-independent processes are also called such reactions as they are not primarily guided by light.
The Calvin cycle processes can be separated into three main channels: carbon fixation, reduction, and starting molecule's regeneration as explained below:
- <u>Carbon Fixation:</u> Six-carbon compound are generated in this step that bifurcate into two molecules (three-carbon compound) 3-phosphoglyceric acid (3-PGA), catalyzed by the enzyme rubisco or RuBP carboxylase/oxygenase.
- <u>Reduction: </u> In this phase of the cycle 3-PGA molecules are converted into glyceraldehyde-3-phosphate (G3P) i.e three-carbon sugar by using ATP and NADPH.
- <u>Regeneration:</u> Many G3P molecules are used to generate glucose, while others have to be recycled to recreate the acceptor RuBP.
