This is the simplest form of lipid<span> made from three fatty acids with an ester linkage to a glycerol. Most triacylglycerols found in nature are from </span>two<span> or more different fatty acids. They are relatively insoluble in water and hydrophobic due to the non-polar nature of the aliphatic portion of the fatty acid chains.</span>

You are telling your friend that organic molecules are all made up of carbon backbones with hydrogens. She doesn't understand ho
Assoli18 [71]

Answer:  They possess different functional groups.

Explanation:

Organic compounds are molecules composed of many carbon atoms bound together and in turn bound to hydrogen atoms. These molecules form the lipids, proteins, carbohydrates and nucleic acids that constitute all living beings. The reason why there is so much variety of organic molecules is because each one can have one or several <u>functional groups in different positions, which gives them unique properties.</u>

So a functional group is a group of atoms linked in a certain way, which present a specific physical-chemical structure and properties that characterise the organic compounds that contain them.

Examples are:

  • Lipids: A carboxylic acid
  • Proteins: A carboxyl group and an amino group
  • Carbohydrates: An aldehyde or ketone group
  • Nucleic acids, Nucleotides: A phosphate group

it takes light from the sun about three minutes to reach mercury how many hours does it take light from the sun to reach Neptune
Kazeer [188]

The time taken to reach the Neptune planet is 4.2 hours

<h3>What is the time taken?</h3>

We can see that the speed of light has the value of 6.7 * 10^8 miles per hour . We also know that the solar system is composed of the sun and the planets. The distance of the between the sun and mercury is 35,000,000 miles while the distance between the sun and Neptune is  2.8 x 10^9 miles.

This implies that the ratio of the distance from neptune to the sun and that of mercury to the sun is;  2.8 x 10^9 miles/3.5 * 10^7 miles hence Neptune is eight times farther from the sun than mercury.

The time taken for light to reach Neptune from the moon is;

Distance = 2.8 x 10^9 miles

Speed = 6.7 * 10^8

Time = 2.8 x 10^9 miles/6.7 * 10^8

= 4.2 hours

Missing parts;

Mercury is the closest planet to the Sun, with an average distance of 35,000,000

miles.

It takes light about 3 minutes to travel from the Sun to Mercury.

Neptune is the farthest, with an average distance of 2.8 x 10 to the power of 9 miles from the Sun.

How many times farther from the Sun is Neptune than Mercury?

How long does it take light to reach neptune?

Which base is normally used in the synthesis (making) of RNA but not in the synthesis (making) of DNA?
fiasKO [112]

The correct answer is uracil.

<span>Uracil is one of the pyrimidine nucleotide bases which is the component of nucleic acid-RNA. In RNA, uracil binds to adenine via two hydrogen bonds (complementary binding). Uracil is not found in DNA, it is replaced by thymine because it is thymine’s demethylated form.</span>
