This is referred to as the critical concentration, it is the exact concentration of the subunits that allows for equal growth and degradation of the filament.
Answer:
Two back-to-back phospholipid layers with the polar heads facing out on both sides
Explanation:
Phospholipids are made up of a head and two tails. The head can be described as a phosphate molecule that is water loving (hydrophilic) whereas fatty acids make up the two tails. The fatty acids repel water and hence are hydrophobic. The assembling of the phospholipids for the the formation of cell membrane depends on these hydrophilic and hydrophobic properties. The assembling of the phospholipids is in two layers. The phosphate head face outwards on both sides to attract water and the tails tend to hide from the water molecules by being composed in the layers of the head. this assembling is termed as the "self-assembly".
The virtually universal decline in near vision in middle adulthood is called presbyopia.
<h3>What is vision?</h3>
Vision is the ability of the eyes to receive and send signals to the brain which then interprets and produces a picture of the object.
A common eye defect the occurs as people grow into adulthood is known as presbyopia.
In conclusion, presbyopia is an age-dependent eye defect.
