In a newly fertilized egg, the vitelline layer ______. A. lifts away from the egg and hardens to form a fertilization envelope B
klasskru [66]

In a newly fertilized egg, the vitelline layer lifts away from the egg and hardens to form a fertilization envelope.

Therefore, the correct answer is Option A.

<h3>What is vitelline layer?</h3>
  • Vitelline layer or vitelline membrane (VM) is a structure that surrounds the outer surface of the plasma membrane of an egg or ovum. In some organisms (e.g.: birds), the vitelline layer surrounds the extracellular yolk and the ovum.
  • It is multilayered and functions to protect and give shape to the egg yolk and separate it from the egg white.
  • VM consists of protein fibers and protein receptors necessary for sperm binding.
  • As its function is to provide support and protection to the yolk, after fertilization, the vitelline layer gets hardened and separated from the yolk to form fertilization envelope.

What is the best course of action when a food handler has questions about how to properly wash their hands?
Brilliant_brown [7]
I would say the best course of action would be to actually show them ie demonstrate good hand washing activity what with soaping up a lather and washing both the inside and outside of the hands for awhile to ensure no bacteria will be introduced to the food and also ensure the food handler uses neoprene disposable gloves when handling food.
