So the +3 part is where you start. so put a point on (0,3) because the +3 tells you to do that. then you have to remember rise over run. since it is a negative you will be going down. so go down 5 and then right 2 and put a point on where you landed at. then draw the line through to two points.
Rough endoplasmic reticulum, Golgi apparatus, cell membrane are structures that a protein that is destined to leave the cell would interact with on its journey from synthesis to exile from the cell of his birth.
The ribosomes, which are the molecules in charge of producing proteins, are what give the rough endoplasmic reticulum its name. A specific RNA fragment may instruct a ribosome to move to the rough endoplasmic reticulum and embed itself if it comes across there. The protein produced from this region will wind up inside the rough endoplasmic reticulum, where it will fold and be marked for transport to the Golgi apparatus through the process of glycosylation, which involves the addition of a tag molecule (often a carbohydrate).
Near the nucleus, the rough endoplasmic reticulum, which is continuous with the nuclear membrane, resembles a network of canals. Rough endoplasmic reticulum-produced proteins are either meant to form a membrane or to be released from the cell membrane. It would be much more difficult to discern between proteins that should exit the cell and proteins that should remain if there were no rough endoplasmic reticulum. As a result, the rough endoplasmic reticulum promotes cell specialization and increases organism complexity.

Answer:
Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion
Explanation:
Transport proteins generally perform two types of transport: “facilitated diffusion,” where a transport protein simply creates an opening for a substance to diffuse down its concentration gradient; and “active transport,” where the cell expends energy in order to move a substance against its concentration gradient
