For a species with a diploid number of 26, indicate how many chromosomes will be present in the somatic nuclei of individuals th
zhuklara [117]

Answer:

<h2>Haploid=13</h2><h2>triploid=39 </h2><h2>tetraploid=52</h2><h2>trisomic=14 </h2><h2>monosomic=12</h2>

Explanation:

Given;

A species with a diploid number of 26,  so 26= 2n ( a diploid cell),

so in haploid condition, chromosome number becomes half (13 in this case). triplod is when 2n + n, and 2n +2n ( tetploid). Trisomy and monosomy is the addition or deletion of a sinlge chromosome of a sinlge set  .

Haploid=13, one chromosome from each pair of chromosome set,

triploid=39 (13× 3); diploid+ n( 3n)

tetraploid=52 (13× 4) 4n

trisomic=14 (13+1) ; n+1

monosomic=12 (13-1); n-1

Explain each of the following, giving a named example in each case:
gogolik [260]
(a) solute = substance (solid or liquid) in lesser amount, which will [dis]solve into the solvent

(b) solvent = substance (liquid) in larger amount, which [dis]solves the solvent
it's dissolvability is called "solvency"
water is known as the universal solvent because it is abundant on Earth and has a high solvency

(c) solution = the combination of solvent + solute
depending on the saturation of solute within solvent, the solution may appear clear, like the solvent

**think of warm sugar-water (solution), when all the sugar (solute) dissolves into the water (solvent), the solute seems to have disappeared
