An organism that reproduces sexually has a diploid number of 30. How many
Strike441 [17]

Answer:

Gamete of organism has a haploid number of chromosomes.

2n = 30

n = 15

A diploid cell containing 30 chromosomes will result in 15 chromosomes in each of the 4 daughter cells after meiosis occurs.

After first nuclear and cellular division (Meiosis I), each daughter cell will only have 15 chromosomes as homologous chromosomes are broken apart at Anaphase I of meiosis I. Chromosomal number is halved. After the second nuclear and cellular division (Meiosis II), each daughter cell will also have 15 chromosomes. This time, instead of the chromosomal number being halved, their chromosomal contents are halved. Sister chromatids are separated at Anaphase II of Meiosis II, resulting in daughter chromosomes each.

Hope it helped!(:

How could the movement of tectonic plates create another supercontinent like Pangaea
Margaret [11]
<span>When the landmasses are again collected together in a specific area

The Pangea theory supports the theory of plate tectonics because it is based on the idea that all the present continents were one super-continent. For reasons still unknown, the super-continent got separated and created separate smaller continents. This theory also supports the fact that this movement will continue until the day arrives when all the smaller continents will again merge in a different configuration to create another super-continent. </span>
