Answer: Kingdom
Explanation:
The linnaean system of classification used in taxonomy start from highest (most general category) to the lowest level as follows: Kingdom --> phylum/division --> class --> order --> family --> genus --> species.
Thus, since the first level (Kingdom) require species to have the least number of common features, the most species are found in it.
For instance: living organisms of all species are classed into just 5 kingdoms whereas over a billion species exist.
Cholesterol is an example of an amphipathic molecule, whereas all the above options affect membrane fluidity.
<h3>What is an amphipathic molecule?</h3>
An amphipathic molecule is a compound that has a hydrophilic region and a hydrophobic region.
Phospholipids are the main constituent of the cell membrane and this lipid matrix.
The number of double bonds in hydrocarbon tails affects membrane fluidity by generating a "kink" in the fatty acid chains.
Cholesterol content alters fluidity because this lipid has free movement in the membrane.
Phospholipids and steroids such as cholesterol are amphipathic molecules, whereas membrane fluidity refers to the movement of the constituents of the cell membrane.
In conclusion, Cholesterol is an example of an amphipathic molecule, whereas all the above options affect membrane fluidity.

Answer: Option D.
Explanation:
Insufflation is a method which is used as a route of administration for drugs through nasal cavity.
The nasal cavity is having a thin vascularised mucosal layer, therefore during Insufflation when a drug molecule is administered, it transferred quickly across the layers of epithelial cell directly into lymphatic system and starts it"s effect within 5 minutes.
Hence, Insufflation is a method which is used to absorb drugs through mucosal membrane.

Answer:
The cortisol is generally nothing but a hormone of a steroid category, which is produced by the adrenal glands as a reciprocation to any type of stress or low concentrations of glucose in the blood, also called glucocorticoid. It plays an essential role in all the vertebrates as it is accountable for conducting various activities associated with the metabolism, cardiovascular system, homeostasis, and immunity.
The glucocorticoid receptors or the cortisol receptors are found to take place in the cytoplasm and carry the heat shock proteins alongside. When the hormone reaches these receptors and combines with them some modification in their conformation takes place, and two things occur, that is, the heat shock proteins are discharged, and a complex is produced by the hormone and the receptor, known as the G. R complex.
This complex exhibits the tendency to move into the cytoplasm and performs the process of translation and transcription by combining it with the DNA. Here, it again can do two kinds of activities, that is, via transactivation it can result in the expression of the inflammatory proteins in the cytoplasm or via transrepression, it can repress the similar proteins.
