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: Options are not given, here are the options.
a.Thylakoid membranes become more permeable to ions
b.The chlorophyll breaks down
c.The peripheral proteins lose their ability to bind to the transmembrane proteins
d.Water cannot bind to PSII to form oxygen
The correct option is C.
The peripheral proteins lose their ability to bind to the transmembrane proteins.
Explanation:
In photosystem 11, it is the center where light is converted to moving electrons. When the chlorophyll molecule absorb light, the electrons gain energy.
Increase temperature affects the activity of photosystem 11 because the peripheral protein lose their ability to bind to the transmembrane protein which is as a result of high temperature affecting the surface of ionic interactions which is for binding to transmembrane protein.

Answer:
According to the case history, Mrs.Wharton is a 59-year-old woman who presented in the dermatologist's office with a complaint of changes in a mole or a<u> nevus.</u>
Explanation:
The correct answer to complete the sentence is the term "nevus". A nevus (plural:nevi) is the medical term for the word mole, which in most occasions is what patients will use to describe the condition. A nevus or mole are the product of a collection of colored cells, and are very common among people, with the average of 10 to 40 nevi per person. Although most nevus are harmless in their nature, it is important for everyone that has one to check them regularly, and in the case that the person sees a change in the appearance of the nevus he/she should go to the doctor's office for a medical examination, just like Mrs. Wharton did.
