Proximity, similarity, closure and simplicity
The right answer is non rebreather.
A non-rebreather mask (NRB) is mainly used to provide oxygen to treat hypoxia, in which arterial blood oxygen saturation is less than 90 percent.
Non-rebreather masks offer an increased level of moisture towards the nasal passage, which can become inflamed and irritated with prolonged oxygen treatment. Increased humidity also increases the patient's respiratory secretions.
Answer: <u>Fungi
</u>
Explanation:
Organisms with the capacity to breathe anaerobically and aerobically are typically called obligate anaerobes. Obligate anaerobes are usually microorganisms- microscopic organisms.
Since the organism described is land-dwelling, chitinous and eukaryotic (containing a plasma membrane enveloped nucleus), they are most likely fungi. Chitin is a rigid, non-soluble carbohydrate utilized for structural purposes. Typically these organisms have strong, insoluble cell walls, are multi-cellular and can form filamentous networks of hyphae.
They create a tangled network of mycelia and may be:
- Septate, with walls between every cell or
- Aseptate without walls
Answer:
Because proteins and lipid tails are free to move and are not bonded by strong interactions with each other.
Explanation:
The plasma membranes have two layers of phospholipids in which proteins are present. The hydrophobic fatty acid tails of phospholipid layers make the inner core of the membranes. However, the tails are not bonded to each other and make a fluid-like base in which proteins are present. Also, the membrane proteins are not bonded to the phospholipids and are free to change their position within the phospholipid leaflets. This is why the model is described as a fluid mosaic model.
