Question

What must happen before meiosis can begin

DNA replication must come first before meiosis to happen.Previous to replication, a germ cell contains two copies of each chromosome, a maternal  copy. and a paternal copy.

The replication of chromosome is followed by meiosis.

Before meiosis really starts, the DNA that is bundled into chromosomes must be completely duplicated. Past to replication, a cell of germ contains two duplicates of every chromosome, a maternal copy and a fatherly copy. The maternal and fatherly homologs depict the maternal and fatherly hereditary contribution to every cell and guarantee that every cell has a half hereditary make-up originating from each parent. These two chromosomes are autonomous yet fundamentally the same as and are named homologs of one another.  

DNA replication happens in a similar manner as it does during mitosis. After replication, the homologs are multiplied, and every chromosome presently has a homologous pair.

the correct answer is: d. the saltine and pretzel are made of flour, yeast, and baking soda, and salt. the pecan contains no flour but it does contain fats. the pecan is a nut that can be consumed as a healthy snack. first of all, pecans are a source of fat (monounsaturated fat), but they provide less fat than some other nuts. pecans are a rich source of dietary fiber, manganese magnesium, phosphorus, thiamin, vitamin e…

b tumor cells have a cell wall instead of a membrane

explanation:

tumor cells different from normal cells because tumor cells have a cell wall instead of a membrane.
