Answer:
A <u><em>receptor</em></u> is a protein that recognizes and responds to a signal.
Explanation:
A receptor is a protein molecule present on the cells on which the signalling molecules can bind and generate a physiological response. Some receptor molecules can also respond to Sun and light. Each type of cell has specific receptors molecules and hence can respond to specific signals. The receptor molecules hence tend to receive signals for a cell. Molecules such as hormones bind to the receptors.
The option that has the most potential of experiencing background extinction based on the natural disruption is : ( C ) A species that will not grow during a specific season every year
<h3>What is Background extinction </h3>
Background extinction is the gradual extinction of species due certian environmental factors such as change in weather conditions, disease, competitive disadvantage and habitat loss.
A population that will not grow during a specific season every year will experiences a gradual extinction process while other options will experience a fast and sudden extinction process.
Hence we can conclude that the most potential of experiencing background extinction based on the natural disruption is : A species that will not grow during a specific season every year.
