<span>Foreshadowing means B. hinting at things that will occur later. Sometimes authors may introduce a symbol or a character so as to show the readers that something awaits them in the following chapters, but he or she will not reveal immediately what that actually is. The other examples don't really make any sense and do not refer to what foreshadowing actually is.</span>
Answer:
The rapid decolorization with ethanol or acetone
and counterstaining with safranin
When a decolorizer such as alcohol or acetone is added, it interacts with the lipids of the cell membrane. A gram-negative cell loses its outer lipopolysaccharide membrane, and the inner peptidoglycan layer is left exposed: when safranin is added they will turn red. Conversely, gram-positives retain the Cristal violet and will color in purple
Answer:
Protozoan infection of the intestines. Giardiasis forms cysts and travel through the feces so anything that comes in contact with the feces and the animal has consumed it will host the parasite.
Explanation:
Answer:
The prime function of the GTPase activity of the G-alpha protein is to perform the hydrolysis of the attached guanosine triphosphate or GTP. Upon combination with the GTP, the G-alpha protein becomes activated, and when hydrolysis of GTP takes place to guanosine diphosphate or GDP, the G-alpha subunit becomes inactivated.
Therefore, the activity of the GTPase provides the G protein-coupled signaling mechanism's regulation. In case, if the mutation takes place within the gene encrypting the G-alpha subunit, then the inhibition of GTPase activity occurs, which would eventually result in the following outcomes:
1. The stimulation of the signaling pathway may take place for a prolonged time duration, eventually causing an unwanted differentiation of the cell.
2. There would be a spontaneous enhancement in the concentration of cyclic-AMP within the cell.
3. The activation of the G-alpha subunit would take place for a prolonged time duration.
