The question was incomplete but I managed to found it some other source. Please find that in the attached picture.
Answer:
<u>The earliest step: </u>
Formation of amino-acid building blocks
<u>The second step: </u>
Joining amino-acids into a polymer like beads on a string (this order is the 'primary structure')
<u>The third step:</u>
The first part of the protein folds due to side-chain and backbone interactions
<u>The fourth step</u>:
The final protein tertiary structure is completed with the addition and folding of the last parts of the protein.
<u>The last of these steps:</u>
The enzymatic function is possible due to the completed tertiary structure creating an 'active site' region of the protein.
Giraffes probably used to have short necks. Over time, since the branches of trees or plants were out of their reach, they adapted to this by having a longer neck. Those with longer necks are able to reach the food and eat it that those with short necks could not. Obviously, those with longer necks are able to survive and therefore reproduce. Because of reproduction, they are able to pass on this characteristic that allowed them to survive on to their offspring. This leads to offspring doing the same and over time, affecting the entire population of giraffes and soon evolving giraffes. This is natural selection doing its work in the evolution of long necks in giraffes.
The ester bonds in lipids are found where the fatty acids of the lipid join to the glycerol back bone of the lipid.
Lipids are made from two kind of molecules namely Glycerol and Fatty acids. A glycerol molecule is made up of three carbon atoms with an alcohol group attached to each of the carbon atoms and hydrogen atoms occupying the remaining positions.
A fatty acids consist of an acid group at the end of the molecule and a hydrocarbon chain.
In a process called esterification, the acid group of the fatty acid joins to the alcohol group of the glycerol molecule and water is released resulting in the formation of a linkage called an ester bond.

Hello User,
All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life.
- Living things are made of cells. Cells are the basic building blocks of living things
- Living things have movement. This movement can be quick or very slow.
- All living things have a metabolism
