Answer:

Laser-assisted in situ keratomileusis

Explanation:

Laser in-situ Keratomileusis (also known by the acronym LASIK) is a surgical procedure based on the use of a cutting instrument called a microkeratome. The surgeon makes a cut in more anterior regions of the cornea and then uses a laser at these locations to reshape the cornea. After this, the surgeon places the cut cornea again at the cut site, allowing this tissue to reintegrate into the cornea within a few days.

Which of the following factors does not affect membrane permeability? View Available Hint(s) Which of the following factors does
Dima020 [189]

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.

The large diversity of shapes of biological molecules is possible because of the extensive presence of _____ in the molecules. t
Yanka [14]

Answer;

Carbon

Explanation;

-The large diversity of shapes of biological molecules is possible because of the extensive presence of carbon  in the molecules.

-The major classes of biological molecules that are important for all living things are carbohydrates, lipids, proteins, and nucleic acids. These molecules differ in structure and function, in part, because of different functional groups.

All organic molecules contain carbon atoms. Biological macromolecules are organic, meaning that they contain carbon. In addition, they may contain hydrogen, oxygen, nitrogen, phosphorus, sulfur, and additional minor elements.

-Carbon qualifies as the foundation element for molecules in living things. It is the bonding properties of carbon atoms that are responsible for its important role.
