Answer:

1. Glycerol

2. Fatty acids

3. Monoglycerides

4. Triglycerides

5. Hydrocarbon

6. Hydrophobic

Explanation:

1. Glycerol

Fat consist of a molecule called glycerol that is attached to one, two, or three fatty acids. Glycerol is the basis of all fats and consists of a three-carbon chain that is attached to the fatty acids.

2. Fatty acids

Fats is made up of three fatty acids and a glycerol, it can also be called triacylglycerols or triglycerides.

3. Monoglyceride

It is a glycerol molecule with a singular fatty acid. It is formed through the combination of OH of glycerol to the OH of the fatty acid.

4. Triglycerides

It has three fatty acid molecules. It is a tri-esters made up of a glycerol attached to three fatty acid molecules.

5. Hydrocarbon

Fatty acids is made up of long, unbranched hydrocarbons with a carboxylic acid group found at one end.

6. Hydrophobic

The hydrophobic nature of fat arises from the carbon-hydrogen bonds that are nonpolar.

Answer:

1. One molecule of glycerol

2. A fatty acid

3. Monoglyceride

4. Triglyceride

5. Long Hydrocarbon chain

6. Hydrophobic

Explanation:

1. A fat molecule is composed of two types of smaller molecules, including only one molecule of glycerol. 2. A fatty acid fat molecule also includes one, two, or three molecules. 3. A fat molecule with only one fatty acid is called a monoglyceride. 4. A fat molecule with three fatty acids is called a triacylglycerol, or a triglyceride 5. A fatty acid includes a carboxyl group (-COOH) at one end as well as a long hydrocarbon chain 6. The hydrocarbon chains found in fats store a lot of energy. They also make fats hydrophobic, or insoluble in water.

Phosphorus (P) is the element with the atomic number 15. Which of the
viva [34]

Explanation:

   Isotopes:

                          ₁₅³¹P   and     ₁₅³²P

     Given parameters:

       ₁₅³¹P                                                   ₁₅³²P          

   Mass number = 31                                    32

   Atomic number = 15                                 15

The two atoms are isotopes. Now let us derive numbers of their subatomic particles

                       ₁₅³¹P                                             ₁₅³²P  

Protons              15                                                 15

Electrons           15                                                  15

Neutrons         (31-15) = 16                               (32-15) = 17

Because they are isotopes, they differ in the number of neutrons alone.

Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass numbers due to the differences  in the number of their neutrons.

We clearly see that the mass number and number of neutrons pertaining to the atom differs. This makes them isotopes.

Why there is uncertainty in science.
andrew11 [14]

Answer: absolute certainty is often difficult to achieve. Scientific uncertainty generally means that there is a range of possible values within which the true value of the measurement lies.

Which structure forms as DNA unwinds? A. a special marker B. a complementary base C. a replication bubble D. a double helix
kozerog [31]

A replication bubble forms as the DNA unwinds.

Option C  

<u>Explanation</u>:  

Replication bubble is the space where the strands of double helical DNA structure are separated with the help of DNA helicase. The strands of the double helical DNA are still in the helix form on the both end of the unwinded DNA stand which gives this region an appearance of a bubble.

DNA unwinding is the first step in replication or transcription of the DNA molecule. DNA helicase separates the two types of "DNA" that are connected by hydrogen bonds with the help of ATP hydrolysis.

What do fats, steroids, and waxes have in common? What do fats, steroids, and waxes have in common? (a) Moderate polarity. (b) L
hodyreva [135]

Answer:

Both (b) and (c)

Explanation:

Fats, steroids and waxes are some of the most common types of lipids. Lipids are non-polar hydrocarbons because of the presence of non-polar carbon-carbon and carbon-hydrogen bonds in there structure.

Generally, polar molecules are soluble in water while non-polar molecules are insoluble in water, hence, lipids do not dissolve in water. There non-polarity also makes them a suitable component in the selectively permeable biological cell membrane.
