Answer:
Asymmetric liposomes have different lipids in outer and inner leaflets, which would greatly increase the flexibility of vesicle in drug delivery systems. It has been well known that the phospholipid distribution in natural membranes is asymmetric. For example, phosphatidyl tcholine and sphingomyelin concentrate at the outer leaflet whereas phosphatidylethanolamine, phosphatidylinositol and phosphatidylserine are mainly localized in the inner leaflet. Typically, Lipids are self-assembled symmetrically in artificial liposomes regardless of the preparation methods. As drug delivery carriers, asymmetric liposomes with advanced functions are appealing candidates for targeted accumulation and controlled drug release. Their outer and inner leaflet could be manipulated depending on the nature of encapsulated drug molecules. For example, asymmetric liposomes help deliver negatively charged siRNA to target organs by having positively charged inner layer that encapsulates siRNA with high efficiency, and negatively charged outer surface prevents nonspecific uptake of the asymmetric liposomes. The unique tunability of asymmetric liposomes opens a wide door for multi-site functionalization, resulting in highly engineered liposomes as advanced drug delivery vesicles.

Answer:
Collections of nerve cell bodies in the peripheral nervous system are called <u>ganglia.</u>
Explanation:
Ganglia are structures enclosed in a tissue sheath, which contains cell bodies of neurons. They also contain dendrites that make synaptic connections between neurons, transporting electrical impulses, connecting the brain with specific organs. They are part of the peripheral nervous and are responsible for connecting the peripheral nervous system with the central nervous system, both in an efferent sense (from the central nervous system to the sensory organs), and afferent (from the sensory organs to the central nervous system).
Answer:
Air is forced to rise over mountains, air cools and condensation occurs, rain falls over the mountains, dry air sinks down the other side of the mountain. Some deserts form in areas that lie at great distances from the sea. The air here is much drier than on the coast.
Explanation:
Answer:
b
Explanation:
<em>The correct answer as to the ocean process that exposes the coastal organisms to land-based predators would be the daily tidal patterns that leave the coastal area exposed to the land for a part of the day.</em>
Some parts of the coastal areas become exposed to land during certain periods of the day as a result of tidal waves. When this happens, the aquatic organisms occupying these coastal areas become temporarily exposed to land predators who hunt and kill them for food.
<u>Therefore, the correct option is b. </u>
