Answer:

This question is incomplete as it lacks options, however, it will be answered BROADLY so the it can be understood enough to select the correct answer.

Please find the explanation below

Explanation:

Cells perform different functions and look differently because of the process of CELL DIFFERENTIATION. All cells arise from a single stem cell, which then gradually differentiates into different types of cells with different functions, as they divide.

At the molecular level, these different types of cells contain the same DNA sequence as rightly stated in the question. However, they look and perform differently because some of the genes are turned on while the others are turned off via the process of GENE EXPRESSION.

Therefore, a blood cell and skin cell possess exactly the same DNA sequence but look different and perform different functions because of CELL DIFFERENTIATION in which some genes on the DNA sequence are expressed and others are repressed. For example, in the blood cell; the genes coding for certain proteins found in blood are expressed while every other gene is silenced or inhibited. This allows those cells to perform only blood-related functions.

Lipids and proteins.

Lipids are macromolecules which provide insulation
. 
A macromolecule is a large molecule. There are four groups of macromolecules: carbohydrates, proteins, nucleic acids and lipids. Lipids consist of glycerol and fatty acids and are constructed from fats, oils, waxes, phospholipids and steroids. A lipid's function is to insulate the body and provide warmth in cold conditions. It can be concluded that a person with very little body fat gets very cold easily and a person with a lot of body fat gets very warm very quickly.

Proteins are biological macromolecule and mostly composed of enzymes.<span> Proteins play a role in the physical make-up of a cell or acts as a cytoskeleton –maintains cell shape and figure. These proteins plays different roles and works with nucleic acids and other macromolecules in the cells including cell cycle, cell adhesion, immune response and cell indicators. <span> </span></span>

Hey there!

Here is a paraphrased version of the text:

Objects that are nonliving never had the qualities of life, and never will. Things that are dead did have an experience to have the qualities of life, but then they eventually die, they fail to keep some of the characteristics. So in science, dead is not an identical word to nonliving. A rock is nonliving, a fallen tree is dead, and a moose is living.

Note: While paraphrasing a text, a good thing to do is to think of as many synonyms of the words in the text as you can.

Hope this helps you.
Have a great day!
