Answer:
Most liquids become monotonically denser when cooled from room temperature, but liquid water reaches its maximum density at approximately 4°C, below which it expands to become less dense as it is cooled further. To explain this density anomaly, several ideas have been proposed.
Explanation:
Answer & Explanation:
Aquatic plants don't have to deal with drying stress, so, for example, the number of stomas will be lower or even absent. Also, the pressure and temperature conditions underwater are way different than on earth. Therefore, the movement of fluids and metabolic products will be quite different.
Answer:
<em> </em><em>Pseudomonas aeruginosa, Serratia marsescens, Klebsiella pneumoniae or Escherichia coli </em>
Explanation:
Meningitis is the inflamation of the meninges (membranes that cover the brain and spinal cord) due to the infection of the fluid around it. Some of the symptoms are fever, sleepiness, nausea and vomiting, stiff nech and seizures.
Meningitis can be caused by Gram negative bacterie such as<em> H. influenzae., Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa or Serratia marsescens</em>. <em>From these options only </em><u><em>Pseudomonas aeruginosa, Serratia marsescens, Klebsiella pneumoniae </em></u><em>and </em><u><em>Escherichia coli </em></u><em>are rod-shaped gram negatives.</em>
