Answer:
The correct answer is option B. It bind to a receptor in the plasma membrane.
Explanation:
Hormones can be aminoacid based hormones (peptide or amine) or the steroid base hormones on the basis of their nature. Amino acid based proteins are molecules that are proteins,
Peptide hormones are the protein or peptide molecule that release in blood by the exocytosis in the form of preprohormones that mature later and bind to the receptor present on the surface of the plasma membrane of the target cell. The binding of the peptide hormone to the receptors a secondary messenger shows up in the cytoplasm.
Thus, the correct answer is option B. It binds to a receptor in the plasma membrane.
 
        
             
        
        
        
Each upward movement of the basilar membrane causes the stereocilia of the inner hair cells to bend, opening K+ gates.
        
             
        
        
        
Answer:
Ancient landmasses
Explanation:
The same fossils being found in widely separate areas can help scientists infer the geography of the continents of that time.
For example: Africa and South America used to be connected during the Permian Period.
Scientists can confirm this because both continents are home to similar fossils.
 
        
             
        
        
        
<span>The
DNA is stored cold with the instagene matrix after boiling samples in order to
slow bacterial growth. In that way, you will greatly slow down the activity of
any remaining enzymes that could harm your DNA. Most likely it is a way of
preserving the DNA and to avoid it bacterial contamination.</span>
        
             
        
        
        
The answer is water vapor.
Water is presented in the form of tiny gas particles called water vapor in the atmosphere. The clouds are formed when this invisible water vapor in the atmosphere condenses onto microscopic particles (dust, dirt,...).
