Platysma is the sheet of muscle that arise from the chest and deltoid muscle. The muscle rises over the clavicle.
Platysma muscle comes upward from the slanting manner by the sides of the neck. This muscle draws the corners of the mouth and lower lip. Hence, platysma muscle is used to express horror and for the pouting.
Thus, the answer is platysma.

Maintaining hip flexion at 90 degrees or less when sitting is the appropriate instructions in which the nurse should include in the teaching to the individual who just went through total hip arthroplasty.
<h3>
What is Arthroplasty?</h3>
This is a medical procedure which involves remodeling of the joint so as to restore its functions. The damaged joint is usually replaced with an artificial one in this scenario thereby ensuring certain types of movements are restored.
The individual should always maintain a hip flexion at 90 degrees or less when sitting so as to prevent the joint from being stressed which helps maintain its functions. This should also be done to avoid the incidence of the dislocation of the joint.
This is therefore the reason why maintaining a hip flexion at 90 degrees or less is the most appropriate choice.

Answer: all of the above
Explanation:
Membrane proteins relays the signals between the cell's internal and external environment. Transport proteins move molecules and ions across the membranes. Cell adhesion molecules allow the cells to identify each other and interact. There are two types of membrane proteins : Peripheral and Integral.Peripheral proteins have weaker and temporary connections to the membrane. Some just sit on the surface, anchored with a few ionic bonds while others might have small sections that dip into the hydrophobic section of the bilayer. Integral proteins are permanently connected to cell membrane.They are hard workers and have large sections embedded in the hydrophobic ( middle) of membrane. Transmembrane proteins are integral proteins that cross the membrane and can act as pathways for ions and molecules. Polytopic transmembrane proteins cross the membrane several times. Some are receptor proteins while others form channels.Ion movement that does not require work is called passive transport while active transport systems use work to move molecules.
