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

Soo-Jung used the subtraction property of equality to solve an equation for y. Which equation could be the one that Soo-Jung sol
antiseptic1488 [7]

Explanation:

Option 1.

4y=12

Dividing 4 both sides

y=3

Division property should be used.

Option 2.

\dfrac{y}{4}=12

Cross multiplying each other,

y=12(4)

y=48

Option 3.

2(4y)=12

Opening bracktet in LHS

8y=12

Dividing both sides by 8 i.e.

y=\dfrac{12}{8}\\\\y=\dfrac{3}{2}

Division property is used.

Option 4.

y+4=12

Subtracting both sides by 4 i.e.

Y+4-4=12-4

y=8

Subtraction property is used.

<em><u>It means that in option (4) Soo-Jung used the subtraction property of equality to solve an equation for y.</u></em>
