Which processes uses a body cell to create a new organism?

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"

Different microbes grow in a wide variety of environmental conditions; however, most have preferences for certain temperatures,

lesya692 [45]

Answer:

this is a TRUE statement.

Explanation:

Different microbes grow in a wide variety of environmental conditions; however, most have preferences for certain temperatures, pH, and atmospheric gases because although microbes are widespread in their occurrence,they are found almost everywhere,in the air,water,soil,food,decaying matter,oil deposits,in plants etc.

but their number and their types vary according to the locality and environmental conditions.

Although, some microbes are always present and contribute towards natural flora BUT besides this others are present in specific environments such as some in hot springs bearing very HIGH TEMPERATURE RANGES for example: Thermus aquaticus.

some of them inhabit the acidic or alkaline soil feeding on HUMUS.

Most of the microbes prefer ATMOSPHERIC GASES i.e some require oxygen for their survival .For example: Pseudomonas.

some don't require O2 for survival i.e Spirochete.

IN SHORT, most of the microbes have preferences for various environmental conditions.
