In prophase 1:
Chromosomes become visible, crossing-over occurs, the nucleolus disappears, the meiotic spindle forms, and the nuclear envelope disappears.
In metaphase 1:
The pairs of chromosomes (bivalents) become arranged on the metaphase plate and are attached to the now fully formed meiotic spindle. The centrioles are at opposite poles of the cell.

<span>A) bacteria. Membrane-bound organelles are found in eukaryotic cells. However, bacteria are prokaryotic, meaning that they do not have membrane bound organelles.</span>
Answer: False.
Explanation:
A normal fault is a type of fault in which the hanging wall drop down in relative to the footwall. It is caused by tensional stress, when two block of rocks pull apart from each other. Normal fault normal happen in areas that are undergoing extension or stretching.
Reverse fault are caused by compressive stress.
