Which of the following characterizes the lag phase of the bacterial growth curve?

Little increase in cell number

Explanation:

There are four distinct phases in the bacterial growth curves that is lag, log, stationary and death phase. The lag phase of the bacterial growth curve is characterized by very little increase in the cell number.

The growth rate of bacteria in the lag phase is slow because the medium is new to the bacterial culture and it requires time for bacteria have to adapt to the new cultural environment and to synthesize enzymes required for substrate utilization.  

After getting adapt in their new environment bacteria starts to grow at an exponential rate. So little increase in cell number characterizes the lag phase.

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure

cuz he's blad
