Answer:
For example, an atom with 6 of 8 electrons in its outer shell will try to gain 2 electrons so its outer shell is full. Ionic bonding occurs when one element donates an electron (or electrons) to another so that both elements will have a full outer shell. As the attractions bring the atoms together, electrons from each atom are attracted to the nucleus of both atoms, which “share” the electrons. The sharing of electrons between atoms is called a covalent bond, which holds the atoms together as a molecule.

<h3>What is umbilical cord?</h3>
- During pregnancy, a tube called the umbilical cord joins you to your unborn child.
- It has three blood vessels: two arteries transfer waste from your baby back to the placenta and one vein carries food and oxygen from the placenta to your baby.
- Because it transports the baby's blood back and forth between the newborn and the placenta, the cord is sometimes referred to as the "supply line" for the infant.
- It provides the newborn with nourishment, oxygen, and waste product removal.
- The umbilical cord begins to grow five weeks after conception.
- Wharton's jelly, a gelatinous substance primarily formed of mucopolysaccharides that shields the blood vessels inside the umbilical cord, is present there.

Answer: The cornea is avascular.
Explanation:
The cornea can be defined as the clear front membrane on the surface of eyeball. It lies in the front of the iris and pupil. It allows the light to enter the eye. A cornea transplant is recommended in patients who suffer from vision problems due to thinning of cornea, keratoconus, loss of vision and cloudiness of cornea.
It takes about 2 to 3 months to recover after surgery. The healing is slow because the cornea is avascular. The tissue of cornea does not provide blood vessels to deliver nutrients and oxygen which could aid in speedy recovery.
