Answer:
Classify each structure according to its functional class.
Compound A contains a carbonyl bonded to two alkyl groups.
Compound B contains an oxygen bonded to two alkyl groups.
Compound C contains a carbonyl bonded to propyl and N H C H 3.
Compound D is a nitrogen bonded to three alkyl groups.
Explanation:
Compound A contains a carbonyl bonded to two alkyl groups.
-C=O group is called a carbonyl group.
If it is present between two alkyl groups then, it is a ketone.
Compound B contains oxygen bonded to two alkyl groups.
Compound B is an example of an ether molecule.
Compound C contains a carbonyl bonded to propyl and N H C H 3.
Compound C is C3H7-CO-NHCH3 which is an amide molecule.
Compound D is nitrogen bonded to three alkyl groups.
This is an example of a tertiary amine group.

I got an idea.
This will be a story. (comic can also be done with this. In fact it is better)
The title is the journey of the ice cube. (change it if you want)
Main character - ice cube
There was an ice cube made by the water from the freezer in an ice shop.
The ice cube, with a bunch of other ice cubes, were taken to be packed and sold to a restaurant. The ice cube was excited to where he was going while the other ice cubes are just meh. Now that the ice cubes arrived, a restaurant worker stores the ice cubes in a cooler and later used to put ice in a lemonade. While the lemonade in a glass cup was carried outside the porch of the restaurant by the waiter, the ice cube was fascinated by the environment of the restaurant. The waiter finally serves the thirsty customer and the customer drank almost half of the lemonade but the ice cube did not get in the man's mouth. Instead the other ice cubes went. The ice cube feared the person. Shortly after checking his phone, the customer was about to reach on to the glass until the hands accidentally pushes the glass over and falls. The ice cube and the remaining ice cubes spread away with the wasted lemonade liquid. No one bothered cleaning up the ice cubes, only the glass shards because the floor is a smooth concrete. Outside was really hot from the sun anyways so it would melt the ice cube and sooner evaporate. As it was in liquid form, the "ice cube" was feeling relaxed because it was just chilling on the floor. And when it evaporates, the ice cubes becomes more fascinated since it goes up to the sky while having a sky-view from above.
That is the end.
You can add, edit or even not consider this one. But this is just an example to spark up your ideas. Sorry if I made some English mistakes.
Hope that it helped
Carbon -14 and Carbon 12 are the two substances geologists use in radiocarbon dating.
Answer: Option B
<u>Explanation:
</u>
Radiocarbon dating denotes the determination process of the age of fossils of plants or animals based on the ratio of carbon atoms 14 to 12. Carbon naturally exists in two non-radioactive isotopes, Carbon-12 and Carbon-13 and one radioactive isotope carbon 14. The carbon 14 gets released on continuous cosmic reaction with atmospheric nitrogen.
These carbon 14 will be absorbed by the living plants and from the plants. Then, it will enter inside the animals which consume the plants. But once the plants and animals died, they ceased to intake carbon-14. In their living state, the ratios of carbon atoms 14 to 12 in them tends to similar to the ratio in atmosphere.
But after they die, the ratio of C-14 to C-12 will be varying from the ratio of C-14 to C-12 in atmosphere as the concentration of C-14 will be decreasing in the dead animals and plants. Thus using this ratio, geologists can find the fossil's age.
Answer:
The correct answer is <em>d. The nucleoside triphosphates have the sugar deoxyribose; ATP has the sugar ribose.</em>
Explanation:
The nucleoside triphosphates are components of DNA (deoxyribonucleic acid) so they are composed by a nitrogenous base (adenine, guanine, thymine or cytosine) and a deoxyribose sugar. In contraposition, ATP (adenosine triphosphate) is composed by the nitrogenous base adenine and a ribose sugar along with three phosphates groups. Unlike ribose, deoxyribose is a 5-carbon sugar which lack of an oxygen atom in C2 position.
