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.
Most important and abundant one are the phospholipids - amphiphatic molecules with an hydrophilic head and a hydrophobic hydrocarbon tails. They compose the membrane bilayer. Also important are the membrane proteins, which can be periheric and internal and can serve as channels, receptors, pumps etc.
Depending on the cell type the membrane can also contain cholesterol (in animal cells, enhances the membrane stability) or hopanes(in prokaryotes, same function as cholesterol) or ether-phospholipids with branched hydroharbon tails(in archaea, make the membranes more stable and resistant to severe conditions, as archaeas are extremophiles)
Karyotyping can give information on a person's sex and chromosomal disorders. It cannot give information on a person's traits and how severe a disorder is.
DNA is the correct answer but next time put answer choices so that people can better answer your questions. Thanks!
