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.
Answer:
Topical order.
Explanation:
Text structure can be defined as words used to describe how a writer or an author organizes his or her words in a literary work.
A topical order refers to a way of structuring a text or organizing a speech based on the main topic and dividing it into several subtopics in logical categories (steps).
In this scenario, Lisa is giving a speech about Pandas. Her speech includes 3 points:
1) Where pandas live.
2) What pandas eat.
3) How pandas reproduce.
Thus, the type of organization Lisa is using is topical.
In conclusion, a speech or text organized in a topical order has its main points organized as subtopics which are well related with the main topic.
Answer:
I think Experimentation :)
Explanation:
apologies if its incorrect.
Answer:
The main purpose of Negative staining is to study the morphological shape, size and arrangement of the bacteria cells that is difficult to stain. eg: Spirilla. It can also be used to stain cells that are too delicate to be heat-fixed. It is also used to prepare biological samples for electron microscopy.
Secondly, what are the limitations of simple staining? Disadvantages. It does not give much information rather than the morphological characteristics of bacteria. Through simple staining, we cannot classify a particular type of organism.
Regarding this, what is an example of a negative stain?
In a negative staining technique, an acidic, anionic dye is mixed with a cell sample. The dye changes the color of the background, not the cells, causing the cells to stand out. India ink is the classic example of a negative stain.
