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
I would agree with your answer of C. As there would need to be calcium to start with and they seem to come from the sarcoplasmic reticulum
Answer:
Red algae - acquired plastids by secondary endosymbiosis
Explanation:
Red algae are believed to have undergo a primary endosymbiosis event. Then a second endosymbiosis event created a large group known as heterokonts. During the primary endosymbiosis event red algae acquire their plastids.
