Answer:
<h2><em><u>True</u></em><em><u> </u></em></h2>
Explanation:
<u>It's</u><u> </u><u>a</u><u> </u><u>true</u><u> </u><u>statement</u><u> </u><u>as</u><u>,</u>
- When we inhale the diaphragm moves downwards and the rib cage moves upwards and outwards to let enter the outside air containing oxygen come in.
- While we exhale the diaphragm comes to its position and the rib cage move downwards and inwards to let out the inside carbon-dioxide and other games out.
<u>Hence</u><u>,</u><u> </u><u>we</u><u> </u><u>can</u><u> </u><u>conclude that</u><u> </u><u>breathing involves the movement of diaphragm and Rib cage</u><u>.</u>
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
