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

How are conduction and indoction alike and how are they different
PolarNik [594]

Both conduction and induction involve a movement of electrons. Conduction is the transfer of electrons from a charged object to another object by direct contact. Induction does not involve direct contact. Instead, induction is the movement of electrons from one part of an object to another as a result of the electric field of the second object.  What is the difference between conductive and non-conductive?  Conductive materials are good conductors of heat or electricity. Nonconductive materials are not good conductors of heat or electricity. I hope this helps! :)
