A 24-year-old male arrives at the emergency department via air transport after sustaining a fall while rock climbing. The patient is unresponsive with sluggishly reactive pupils upon arrival. His right arm and bilateral lower extremities have obvious fractures. He was intubated by EMS and requires mechanical ventilation. A CT scan reveals multiple head bleeds and intracranial swelling with a midline shift. The patient is rushed to surgery with the plan to relieve the pressure of the intracranial swelling. -The RN prepares to administer hypertonic saline.Which of the following solutions would you expect the physician to order to produce the desired physiologic effect in the patient?

The term obligate refers to ________.

Which of the following is not a major element of a microbial cell?
