Answer:
a space entirely devoid of matter
Answer:
Distinctive characteristics of the cell membrane in the <em>Pseudomonas</em> genus:
- low outer membrane permeability
- protein channels for the uptake of nutrients
- porin proteins with cell adhesion and signaling functions
Explanation:
The plasma membrane is a lipid bilayer that separates the cytoplasm of the prokaryotic cell from the external environment. The cell membrane is selectively permeable in order to regulate the transport of substances (nutrients and cell waste products). <em>Pseudomonas</em> is a genus of Gram-negative bacteria that have a thin peptidoglycan layer and an outer membrane. In <em>Pseudomonas</em> species, the cell membrane contains porin proteins involved in the uptake of nutrients, such as, for example, OprB, OprB2 (glucose), OprG (phosphate) and OprH (pyrophosphate). Moreover, the cell membrane of these bacteria has low outer permeability, which confers a high resistance to antibiotics.
The lower density water occurs in the deep zone of the ocean.
This region of water is cold and stable. Cold water has a higher density as the water molecules are packed more closely together, so they occupy less volume. The difference in density of the regions of ocean is responsible for convection currents.
Lets make a scenario. There is a species of monkey that reproduce in trees, and earthquake rattles the trees causing most of the trees to fall down. They can not reproduce now unless they do so out the trees. Birds for instance may have this problem. Same thing for animals that may live in trees. They can no longer do so.
