Answer:

Used the C1V1 = C2V2 method for calculations

Explanation:

Component Calculation Volume of Stock to be added

FBS: 100*V1 = 10*25 2.5 mL

Glutamine: 200*V1 = 2*25 0.25 mL

Penicillin: 10000V1 = 100*25 0.25 mL

Streptomycin: 10000V1 = 100*25 0.25 mL

NB: C1 = Stock Concentration; V1 = Volume of stock required; C2 = Final concentration required; V2 = Final volume required

<h2>Polychaetes </h2>

Explanation:

Polychaetes is any of the diverse, mostly marine segmented worms of the annelid class Polychaeta, characterized by having most segments with one pair of lateral, fleshy, lobe like appendages called parapodia, with numerous bristles projecting from them
Polychaetes have true segments and anterior to the true segments lie the prostomium and peristomium
This head region of two segments typically contains two pairs of eyes, three antennae, several tentacles, a pair of palps, and the mouth
Polychaeta is divided into Errantia and Sedentaria for convenience
Errantia (scaleworms, sea mice):A subclass of polychaete worms which have a large number of body segments, those of the head and posterior differing from the rest,the mouth often has several paired jaws
Most are vagile predators, others adopt a burrowing mode of life and are first recorded from the Cambrian
Sedentaria (bamboo worms, coneworms):A subclass of entirely marine worms in which the body segments and parapodia differ along the length of an individual,all Sedentaria are burrowers or tube-dwellers and are first recorded from the Ordovician
