Q1. Harry is hospitalized with bacterial pneumonia.

While you visit him, his teeth are chattering, his skin is cool and clammy to touch, and he complains of feeling cold even though his room is quite warm. Elucidate his symptoms.

Q2. As humans breathe, oxygen is taken in and carbon dioxide is expelled. This process is often called organismal respiration. Cellular respiration is a metabolic pathway that degrades biomolecules like glucose to obtain the energy stored in their chemical bonds. Describe how organismal respiration and cellular respiration are interconnected.
