Explanation:
The phase of Prophase I of meiosis is very long and divided into 5 subphases: Leptotene, Zygote, Pachytene, Diplotene, and Diakinesis. During a phase of the Diplotene, the degree of condensation is high, which allows individualizing the sister- chromatids that remain attached by the cohesins. The synaptonemal complex disintegrates, and from the centromeres begins a repulsion between homologous chromosomes, which remain associated only with the places where they occur as permutations.
These sites are called chiasmas (Greek, crossed) because they show the crossover of homologous chromatids. Chiasmas represent the cytological finding of the occurrence of permutation. The presence of at least one bivalent chiasm is essential to ensure the correct segregation of the homologous chromosomes in anaphase I.
Is there multiple choice?

Answer:</h2>
<u><em>The answer is C.</em></u>
Explanation:
They explained that "Investigator Murray decides to try to retrieve mtDNA from the sample and compare it to a sample from her suspect. What information could this sample give her?"
<u><em>mtDNA:</em></u> Mitochondrial DNA (mtDNA) can also be useful to investigators and is found in the energy-producing organelles called mitochondria. This type of DNA can sometimes be recovered from evidence that is too degraded or old to yield regular DNA. Although mtDNA can't be linked to one individual, <u><em>it can show that subjects are maternally related, since it is passed down through the maternal side of the family. </em></u>

Note to you:</h2>
I took the test and the definition of mtDNA (also known as Mitochondrial DNA) came from my notes. Have a good one and I hope it helps!! :)
The given statement is False
Bleach such as chlorine when mixed in fertilizers acts as a killing agent for plants .The bleach runoff is not affected by the fertilizers containing bleach as they do not kill the Aquatic flora. Marine bleaching is caused due to high temperature of water not because of the fertilizers. In marine bleaching the coral will expel algae when the temperature of water is high. These results in discoloration of corals making them white and they can survive in this condition. This proves that the bleaching inside the marine system is because of high temperature not because of runoff.
The equivalent versions in reptiles are scales
(analogous to the cuticle) and the amniotic egg (analogous to the seed). Recall
that the cuticle seals plant surfaces and helps plants conserve water, and the
seed helps derived plant groups to reproduce effectively on dry land.
