Crossing over (exchange of genetic information between regions of non-sister chromatids in the tetrad) occurs in the prophase I stage of meiosis.
<h3>WHAT IS MEIOSIS?</h3>
Meiosis is the process whereby a single cell produces four daughter cells that are genetically different from one another.
Meiosis is able to ensure genetic diversity in the daughter cells due to a process called Crossing over.
Crossing over is the exchange of genetic material between the non-sister chromatids of homologous chromosomes. It occurs in the prophase I stage of meiosis.
Therefore, crossing over (exchange of genetic information between regions of non-sister chromatids in the tetrad) occurs in the prophase I stage of meiosis.

I believe it's B and C because "Chloroplast" and "Vesicle" are found in plants not animals
Answer: 3.2 x 10^ -7
Explanation: move the decimal until there is one number in front of the decimal and then count how many places you moved the decimal and because it becomes a smaller number, the exponent is negative
