Answer:
Explanation:
The bacteriostatic antibiotics can be defined as those antibiotics, which prevents the growth of bacteria. These keeps the growth of bacteria in the stationary phase so that bacteria cannot cause harm to the host.
The bactericidal antibiotics can be defined as those antibiotics, which kills the bacteria.
The example of bacteriostatic antibiotic is Tetracycline that it inhibit the bacteria ribosome production of proteins. This way bacterial growth and reproduction will get restricted.
The example of bacteriocidal antibiotic is polymyxin B. It causes injuries to the plasma membrane of the bacteria which can be lethal for bacteria.
Answer;
As liquid water freezes, the molecules arrange themselves in a way that takes up more space than liquid water. What would most likely occur if the arrangement of frozen water molecules required less space than that of liquid water molecules? A).The density of ice would be greater than the density of liquid water, and ice would not float. B). Ice would form in layers, and liquid water would get trapped in between the layers. Liquid water would have a higher specific heat, making it less likely to undergo vaporization. C).The freezing point of water would decrease, making ice more difficult to form.
Answer:
they bind to protein-coupled transmembrane receptors with higher complexity than those found in prokaryotes
Explanation:
G-proteins are proteins found inside the cells that function as molecular switches which are activated by binding to guanosine triphosphate (GTP), while they are inactive by binding to guanosine diphosphate (GDP). The G-proteins bind to G-protein-coupled transmembrane receptors (GPCRs) in the cytoplasmic region. The GPCRs are a very diverse group of proteins that are activated by extracellular molecules ranging from small peptides to large proteins, including pheromones, neurotransmitters, light-sensitive compounds, etc, thereby allowing them to respond to diverse stimuli from the extracellular environment. In consequence, it is reasonable to suppose that the signaling pathways in which G proteins are involved have a higher complexity level than those observed in primitive prokaryotic organisms.
