The choice that best describes when a cell becomes 2n is : ( C ) after meiosis when froming a zygote

<h3>Mitosis vs Meiosis </h3>

Mitosis is a single round division of a parent body cell which produces two ( 2 ) identical diploid daughter cells ( 2n cells ). while Meiosis is the divison of parent gametes which produces four ( 4 ) haploid daughter cells. Meiosis leads to the production of gametes.

Hence we can conclude that The choice that best describes when a cell becomes 2n is : after meiosis when froming a zygote

It is not always possible to measure every individual in a population; what is the name of the representative group?
ra1l [238]

Answer:

d. sampling unit

Explanation:

<u>Sampling unit:</u>

Refers to the unit or group of elements that are selected from an original population during an investigation. The sampling unit might be composed of a statistical unit or a group of statistical units.

The statistical unit or element is the elemental unit that composes the target population.

The sampling unit is a basic concept to keep present during the development of the investigation project. It is the minimal unit of observation that will be used to take information about the variables of interest.  All the sample unit composes the population and is defined by an <em>N</em>, while only some representative sample units compose the sample, and are represented with an <em>n</em>.

So, the whole population can not be measured because of its size, or the individuals´ characteristics, among other many factors. So we need to take a random and representative sample or group of the population to proceed with our investigation. This sample or group is composed of some of the original population individuals, which are defined as "sample units".

Describe the anaerobic environment where lactic acid is produced. And describe the anaerobic environment where alcohol is produc
miskamm [114]
I’m not too sure what you mean by “aneorobic environment” but alcohol is produced by alcoholic fermentation. Lactic acid is produced in lactic acid fermentation, but they both start off with glycolysis because the whole point of fermentation is basically to produce oxygen when your body can’t inhale enough.

Which amino acids is good for cross linking?
Bezzdna [24]
To measure cross-linking amino acids in a collagen hydrolyzate using a conventional amino acid analyzer with ninhydrin detection, the bulk amino acids must be largely removed to avoid plugging the reaction coil. Tissue is thoroughly reacted with sodium borohydride to convert all intermediate cross-linking residues to their reduced, acid-stable forms. More vigorous reduction conditions may be used than when preparing profiles of tritium-labeled cross-links using NaB3H4<span> and direct amino acid analysis. </span>
