Sarah wants to know which brand of nail polish lasts the longest without chipping. She buys 4 types of nail polish – Essie (whic
Gwar [14]

Answer:

This is an example of scientific investigation and all the elements that compose it.

Explanation:

Sarah is doing a scientific investigation regarding the nail polishes she uses. We can see this, because Sarah is using the elements that make up this type of investigation to reach a conclusion about the enamels. These elements are:

Independent variable: Element that influences the appearance of a controlled and evaluable result, such as the enamel that Sarah will use on her nails.

Dependent variable: Element that is influenced by the dependent variable and promotes the visualization of a result, such as the length of time that the enamels can remain on the nail without chipping.

Experimental group: Element that allows the study of the interaction of these variables and the result developed through it, such as Sarah's enamel marks.

Control group: Element where only the independent variable is applied. As the action of the dependent variable does not exist, the observed result is the same that would be perceived if the study was not taking place, such as the day when Sarah did not paint her nails.

Constant: Elements that are exactly the same throughout the experiment, such as the person who conducted it, the time the study will be carried out, the nail care routine and the lower and upper layers of the enamels used.

How does asymmetric liposome work? Who can tell me detailed information? Any help would be appreciated. Thanks in advance!
Gnesinka [82]

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.
