% concentration (expressed as a proportion or ratio) x volume needed = mass of reagent to use

So... 10% (w/v) solution of sodium hydroxide x 200 mL needed = 20 grams of sodium hydroxide

How many grams of sodium hydroxide are required to prepare a 200 ml solution of a 10% (weight per volume) solution? (Atomic weights: Na = 23; 0 = 16; H = 1)

Insulin is the hormone that is mainly responsible for the entry of glucose into the cell for energy production

Glucagon and epinephrine promote glycogenolysis, conversion of glycogen to glucose, which increases plasma glucose. Cortisol, along with glucagon, increases gluconeogenesis, formation of glucose from noncarbohydrates, which also raises plasma glucose concentration.

Chemistry

Which of the following hormones is mainly responsible for the entry of glucose into the cell for energy production?

Conversion of only the slant to a pink color in a Christensen's urea agar slant is produced by bacterial species that have weak urease activity. The reaction in the slant to the right is often produced by Klebsiella species, as an example. Strong urease activity is indicated by conversion of the slant and the butt of the tube to a pink color, as seen in the tube to the left. The slant only reaction in the right tube may be seen early on if only the slant had been inoculated; however, with a strong urease producer, both the slant and the butt would turn. Therefore, the reaction is dependent on the strength of urease activity. If the media had outdated for a prolonged period, either there would be no reaction or the appearance of only a faint pink tinge, either in the slant, the butt or both, again depending on the strength of urease production by the unknown organism.

The urease reaction seen in the Christensen's urea agar slant on the far right indicates:
