In energy processing systems electronic carrier molecules transfer electrons from one part to other part of energy processing system. This provides the necessary energy and reduces power to carry out chemical reactions. They are necessary for aerobic cellular respiration and photosynthesis.

The hypodermis (subcutaneous tissue) is the innermost layer of skin in your body. The dermis is the middle layer. The epidermis is the outermost layer.
<h3>What does the subcutaneous layer consist of?</h3>
Subcutaneous tissue is the deepest layer of your skin. It's made up mostly of fat cells and connective tissue. The majority of your body fat is stored here. The subcutaneous layer acts as a layer of insulation to protect your internal organs and muscles from shock and changes in temperature.
<h3>What is not found in dermis?</h3>
The answer is C fat cells. So the dermis is between the epidermis and the subcutaneous tissues.

Gel electorophoresis moves DNA through a matrix that contains molecules which prevent large ones from moving but the smaller ones are able to pass through. This allows molecules to be separated by size.</span>
Answer:
The polarity of membrane phospholipids
Explanation:
The inner core of membranes is made of nonpolar tails of phospholipids which in turn makes the membranes impermeable for polar, large and charged substances since these substances cannot cross the non-polar inner core. The saturated hydrocarbon tails pack tightly and make membrane less permeable while cholesterol affects the membrane permeability by interacting with non-polar tails.
Higher temperatures make the membrane more fluid and more permeable while at lower temperatures, membranes are more rigid due to tight packing of hydrocarbon tails and less permeable. The polar heads of phospholipids make the inner and outer surface of the membrane. Therefore, the polarity of phospholipids does not affect the membrane permeability.
