To provide energy to build new cells and tissue
Answer:
c. smear preparation
a. fixation
b. application of staining dyes
Explanation:
In the bacterial specimen preparation and staining order, the first step would be Smear preparation in which the smear of bacteria is formed on the slide.
Then the bacterial smear is heat-fixed so that the smear does not get washed off during the washing process in the staining procedure. After heat fixing the bacterial smear, the dyes are applied to the bacterial smear to stain the bacterial cells.
Therefore the correct order is-
c. smear preparation
a. fixation
b. application of staining dyes
Answer:
ZBWCYAX
Explanation:
Equation for the intermediates: Z↔W↔Y↔X
1) B catalyzes the breakdown of Z, therefore inhibiting B leads to the build up of Z.
2) If enzyme C is inactive then the organism will not receive Y to grow, thus Y is a by-product of C.
3) If A is inhibited then W, Y and Z build except for X, thus it make sense that A catalyzes a reaction that leads to X as a by-product.
4) Inhibiting C leads to the reaction toward making Z and W, thus it catalyzes the breakdown of C directly and Z indirectly.
The correct answer is: E) cleavage furrow formation and cytokinesis
Cytochalasin B (cytos-cell and chalasis-relaxation) is a molecule which inhibit network formation by actin filaments by blocking monomer addition. As a result, itshortens actin filaments. This molecule is involved in cytoplasmic division where it blocks the formation of contractile microfilaments. One of the microfilament’s function includes cytokinesis and formation of cleavage furrow so these functions are affected by cytochalasin B.
