Answer: Read explanation
Explanation: there’s no similarity at all. A cell membrane is made of phospholipids, globular proteins, glycolipids, glycoproteins, and cholesterol, and has passages that serve explicitly for passive and active transport of materials through it.
The skin is made of cells and dead keratin and serves as much as possible to prevent most substances from moving through it. It’s “designed” for toughness and distensibility, not for selective permeability.
Answer:
The endomembrane system includes Golgi apparatus, lysosomes, ribosomes, and the endoplasmic reticulum.
Explanation:
The endomembrane system has some very important function, but mostly it's on a charge of the internal transportation of "things" inside the cell. The system not only transports proteins or RNA or lipids, but it also transports what the cell no longer needs (waste). It starts with the endoplasmic reticulum close to the nucleus, where ribosomes are attached, so it receives molecules from inside the nucleus and also as proteins are synthesized in the ribosomes, therefore it also transports them to the next step which is the Golgi apparatus. The Golgi wraps molecules in a lipid layer and then they are taken to their final destination. Finally, lysosomes process big molecules and take them to a place in the endomembrane system so it can be treated as said before.
Alleles. Alleles are the "same" genes, but provide a variation of the intended function.
