This is the day to day problem of a medical microbiology laboratory: the "tube containing a liquid nutrient medium" in the real world could, for example, represent blood culture bottles (aerobic or anaerobic). The basic process is as follows: a loop is first flamed to ensure sterility and then used to transfer a small portion of bacterial-laden liquid media to the agar medium by streaking it across the surface of a sterile petri dish. The dish is then covered, inverted, and placed in an appropriate incubator. When colonies begin to form on the surface of the agar plate, individual colonies can be taken up using the sterile loop for analysis or further propagation. The assumption is that a single colony represents growth from a single bacterium.
Answer:
a. the mother feels the fetus move for the first time
Explanation:
Answer:
F-actin is a double helical filament as opposed to G-actin,which is a globular protein .Each actin filament has two ends,called the plus and
the minus ends, which makes it recognizable from each other.This gives the structure a distinct polarity.
Explanation:
Actin is the most abundant protein that is found in almost all eukaryotic cells.Its a most important part cytoskeleton as its a monomeric subunits(size 42kDa) of two types of filaments i.e. microfilaments and thin filaments in cells. Actin is essentially required to maintain stability and morphogenesis of cell.It is involved in numerous significant processes such as endocytosis,cell division and migration.Actin is present in two forms:
•G-actin
•F-actin
The two forms of actin are different structurally.
G- actin is a globular shaped protein,usually present in free form(a monomer),having a tight binding site for another actin monomer.Each monomer has ATP. Upon polymerization of G-actin monomers, a polymer called F-actin filaments is form. This process is driven by hydrolysis of ATP.

Species diversity refers to the number of different species in a community or ecosystem. So for example if you have an ecosystem and there are all different areas of that system like water, trees, and ground levels. obviously monkeys do not live in the water so, if you were to affect the water it would more than likely not affect the monkeys directly even though that water IS part of their ecosystem, but it will affect the other animals, living in that water. so if you were to take out a species in that water you are taking away a part of that ecosystem that makes it diverse.
To answer your question, yes the species diversity can decrease after a fire on a grassland.
