Answer: Option E) polar
Amino acid-derived and peptide hormones are unable to diffuse across a cell membrane because they are polar
Explanation:
Amino acid-derived and peptide hormones such as serotonin, epinephrine, dopamine etc, are unable to diffuse across a cell membrane because they consist of several repeating units of amino acids with positively charged or negatively charged side chains.
Thus, the side chains make these hormones water-loving (hydrophilic), and impassable to the hydrophobic layer of the cell membrane.
One potential result of climate change is greenhouse effect that is defined as the accumulation of carbon dioxide in the atmosphere that retains heat radiated from the sun. While this can seem beneficial because plants use carbon dioxide in photosynthesis, elevated levels of carbon dioxide actually inhibit photosynthetic mechanisms (Xu, 2015).
