A - the paper can be burned
this is irreversible
being irreversible is a chemical property
<h2>Monosaccharides</h2>
Explanation:
Monosaccharides are the simplest form of sugars found in innumerable common food items such as honey, cane sugar, fruits
Monosaccharides are divided into two groups depending on the presence of functional groups,if aldehyde group is present then it is known aldoses and if ketone group is present then it is known as ketoses
On the basis of carbon atoms they can be classified as: triose(3),tetrose(4),pentose(5),hexose(6) and so on
a. erythrose : tetrose ketose-It is not correctly paired because erythrose is a tetrose monosaccharide which has one aldehyde group hence is an aldose
b. dihydroxyacetone : triose ketose-It is correctly paired;it is an aldose-ketose pair
c. erythrulose : tetrose aldose-It is not correctly paired because erythrulose is a tetrose monosaccharide having ketone as functional group hence is a ketose
d. fructose : hexose ketose-it is correctly paired;It is an anomer because in D-fructose carbonyl group is at C-2 hence C-2 is the anomeric carbon
e. ribose : hexose aldose-it is not correctly paired because ribose is an aldo pentose not hexose;ribose is an aldo-ketose pair
f. glyceraldehyde : triose aldose-it is correctly paired;an aldo group
_______ Lipid(fat)
Molecules don’t have charge regions in your hydrophobic
<span>A physical system is best characterized as a collection of MATTER THAT HAS DISTINCT BOUNDARIES.
</span><span>How does this phenomenon validate the Law of Conservation of Energy?
</span><span>The light energy travels through the water until it is reflected or absorbed.
</span><span>What conditions would most likely be present in this region?
Organisms growing on bare rock
</span><span>What is the best explanation based on these observations?
</span><span>Lobsters are adapting to cooler temperatures.
</span><span>- Ideal water temperature for lobster is around 53-64 degrees Fahrenheit. With the exceedingly warm waters (68 degrees Fahrenheit), lobsters are forced to move to the north where the temperature is ideal for their life cycles.</span>
