Answer:
to maintain homeostasis
Explanation:
The bionic pancreas is a technology created to reduce and adjust blood sugar levels in patients with diabetes. This external device was developed by Ed Damiano's lab at Boston University. This management system is well known to maintain homeostasis by managing blood sugar levels: the bionic pancreas contains two pumps, one with insulin and the second one with glucagon for controlling the sugar levels when they change in the blood.
Answer:
No harm upon ecosystems or the environment, prevention of any harmful contributions to air, water and land pollution.
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.
Answer:
Education
Explanation:
Education is not among the top sources of stress for Americans according to the American Psychological Association.
