The bacteria have an initial concentration of 1000 cells/cm3 . Each cell divides once every 30 minutes. Calculate how long it wi
Levart [38]

It will take <u>120 minutes</u> for the concentration to become > 15000 cells/cm³

<u>Given data:</u>

Initial concentration ( density ) = 1000 cells / cm³

Target/final concentration = > 15,000 cells /cm³

<h3 /><h3>Calculating the concentration every 30 minutes </h3><h3 />

<em>note</em><em> : Given that each cell divides every 30 minutes </em>

  • <u>After the first 30 minutes </u>

Concentration = 2000 cells / cm³

  • <u>After 60 minutes </u>

concentration = 4000 cells / cm³

  • <u>After 90 minutes </u>

concentration = 8000 cells / cm³

  • <u>After 120 minutes </u>

concentration = 16000 cells / cm³

Therefore after 120 minutes the concentration of the cells will be greater than 15000 cells/cm³ ( i.e. 16000 cells/cm³ )

Explain the statement “Scientific knowledge is the result of debate and conformation within the scientific community.”
spayn [35]

Answer:

What this statement means is that experimentation is not enough, but that true knowledge comes from the analysis of results in a critical and meticulous way

Explanation:

Scientific knowledge is based on the scientific method and the results of the research, however that information is useless if it is not interpreted.

When the results are analyzed by scientists who support the same theories and have the same opinions, the results are not enriched as much as when exposed to different points of view. The debate tests the hypothesis giving rise to more complete answers.

Complete hydrolysis of a nonapeptide gave 3 ala, 2 phe, 2 asp, gly, and ser. Reaction of the nonapeptide with Sanger's reagent (
Wewaii [24]

Answer:

Alanine is obtained as the first amino acid, taking into account that the reaction with the Sanger reagent hydrolyzes N- (2,4-dinitrophenyl) alanine. thus with the fragments of the partial hydrolysis they are organized to create a polypetidic chain

ala-asp-gly-ala

gly-ala-phe

phe-be-wing

be-wing-phe-asp

We obtain that the correct sequence of the peptide is "ala-asp-gly-ala-phe-ser-ala-phe-asp"
