Answer:

for differentiation

Explanation:

By gram staining, we can determine about gram-positive and gram-negative bacteria. If bacteria are Gram-positive then for further catalase test perform. If bacteria give catalase-positive then that's mean this bacteria is Staphylococcus. If bacteria give catalase-negative result then that's mean this bacteria is streptococcus.

The bacteria that are catalase-positive for their further identification coagulase test perform if bacteria is coagulase-positive that's mean it is staphylococcus aureus and if it is coagulase-negative that's mean that maybe differentiation saprophyticus or other species.

Sponges have no "true tissues." what does this mean
artcher [175]
<span>Sponges have cellular-level organization, meaning that that their cells are specialized so that different cells perform different functions, but similar cells are not organized into tissues and bodies are a sort of loose aggregation of different kinds of cells. This is the simplest kind of cellular organization found among parazoans.

What are the phases of Mitosis and what happens in each phase?
Norma-Jean [14]
Interphase: Chromosomes duplicate, and the copies remain attached to each other.

Prophase: In the nucleus, chromosomes condense and become visible. Spindle fibers begin to form.

Prometaphase: The nulcear membrane breaks apart, and the spindle starts to interact with the chromosomes.

Metaphase: The copied chromosomes align in the middle of the spindle.

Anaphase: Chromosomes separate into two genetically identical groups and move to opposite ends of the spindle.

Telophase: Nuclear membranes form around each of the two sets of chromosomes, they begin to spread out, and the spindle begins to break down.

Cytokinesis: The two cells split into two daughter cells, each with the same number of chromosomes as the parent cell.

Katyanochek1 [597]

Interfacial adhesion and surface bioactivity of anodized titanium modified with SiON and SiONP surface coatings, The statement is correct.

<h3>what is adhesion ?</h3>

Adhesion is a type of attraction between two dissimilar phases, the theory of adhesion can be up two types mechanical interlocking and physical and chemical bonding and it is a combination of three methods.

Mechanical interlocking means when two dissimilar phases interact with  one another by mechanical forces, requires a rough surface where the other material can enter.

Physical bonding includes van der Waals forces and the strength  is rather weak and unable to contribute that much bonding strength.

Chemical bonding consist of covalent, ionic and metallic bonding which are more stronger than physical bonds and are responsible for cohesive forces.

chemical bonding between two dissimilar materials is  more complicated due to the presence of few available bonding sites.
