Answer: carbohydrate, protein and fat.
There are 3 kind of macromolecules: carbohydrate, protein, and fat. Carbohydrate mostly found in a plant like rice, wheat, barley. In this case, it's on the pizza dough.
Protein mostly found on muscle or meat. Some meat also has fat because they are not separated when cut, like bacon. Fat found in the subcutaneus tissue of animal or oil. Sausages, pepperoni, and bacon have much protein and some fat.
Since the Pitx1 gene codes for a protein crucial im lower limns development, a mutation occurring near Pitx1 gene will affect refikjs around the lower limbs but not those far away from it.
<h3>What are mutations?</h3>
Mutations refers to alterations or error that occur which change the original sequence of nucleotides in a DNA molecule.
The Pitx1 gene is a gene that codes for a protein that involved in development of the lower limbs.
A mutation near but outside of the coding region of Pitx1 may cause a loss of pelvic fins without pleiotropic effects on the pituitary gland and jaw because the pelvic fins form part of the lower limbs whole the jaws and the pituitary gland are not found in the lower limbs.
Therefore, the mutation occurring near Pitx1 gene will affect regions around the lower limbs but not those far away from it.

The previous statement is true because if a substance cannot get into a cell membrane it is assisted via protein channels however if it doesn't need the protein channels then it just flows through the membrane.
By low temperature, it can melt. High pressure will raise the melting point of the rock.
