Answer: The correct answer is -
b. Threshold.
Explanation:
Threshold can be described as minimum voltage of a memrane (of neuron or muscle cell) that is required to reach an excited state of cell during a depolarization) so as to produce an action potential.
Voltage-gated channels are activated at the threshold voltage, .
For example - Threshold level of neuron is - 55mV, which means it fires action potential at this level so that information is transferred to another neuron.
A substance that provides nourishment essential for the maintenance of life and for growth.
If you do not gain enough nutrients, a nutritional deficiency occurs (when the body doesn't absorb or get from food the necessary amount of a nutrient). Deficiencies can lead to a variety of health problems. These can include digestion problems, skin disorders, stunted or defective bone growth, and even dementia.
<span>amylase is an example of an enzyme</span>
In biochemical reactions, it is mostly triggered by enzymes. Enzymes are important components in the process that involves metabolism and digestive functions, further, most of these enzymes are proteins.Proteins are biological macromolecule and mostly composed of enzymes. Proteins play a role in the physical make-up of a cell or acts as a cytoskeleton –maintains cell shape and figure. These proteins plays different roles and works with nucleic acids and other macromolecules in the cells including cell cycle, cell adhesion, immune response and cell indicators.
Birds have hollow bones due to the fact thay need to be as light as possible for their wings to generate enough lift for them to fly
The answer to this question would be : <span>Clustered</span>
Herpes simplex vesicle has a unique distribution. They are distributed same as the dermatome nervous distribution. Since the dermatome area is limited, then the vesicle on the skin mostly will be placed close together called a cluster. The vesicle might be painful and itchy. Prescribing an analgetic lotion might lessen these symptoms.
