Explanation: vacuole Stores water, waste, food, and other materials or helps sequester waste products
The epiglottis
The cartilage in the throat that guards the entrance to the trachea and prevents fluid and food from entering it when a person swallows is known as the epiglottis
.
The epiglottis is an elastic flap located at the upper end of the larynx in the throat. The epiglottis is the valve that turns passage to either the esophagus or the trachea. The epiglottis allows air to enter the airway to the lungs during breathing, and during swallowing, it allows food and fluids to pass into the gastrointestinal tract.
Answer:
The basement membrane or basal lamina on which the epithelium form, made by extracellular matrix.
Explanation:
The basement membrane is the layer underlies all epithelia that is made up extracellular matrix secreted by the epithelium cells that provide structural support to the structure of epithelia.
It forms the barrier between epithelial tissues therefore once a epithelial cancer penetrate this basement membrane it will spread to all underlying tissues.
Thus, the correct answer is - The basement membrane or basal lamina on which the epithelium form, made by extracellular matrix.
The basement membrane is form of extracellular matrix that underlies all epithelia. It provides structural support to epithelia and forms a mechanical connection between epithelia and underlying connective tissue.
The basement membrane, or basal lamina, is a sheet of proteins and other substances to which epithelial cells adhere and that forms a barrier between tissues.
Epithelial cancers may have the ability to penetrate through the basement membrane and spread to underlying tissues.
Answer:
The largest problem is that single viruses may create multiple plaques, resulting on overestimates of the number of viruses present.
Explanation:
Plague assay allows to measure the concentration of viruses in a sample, it is a widely used approach for determining the quantity of infectious virus. Therefore the amount of plaques created by a single virus is not a concern when evaluating the results of plaque assays.
