I am totally lost when it comes to this stuff I have tried to figure out these answers, but had no luck, so if anyone could help me I would greatly appreciate it.

1.If the chromosome content of one cell at the beginning of Prophase 1 is represented as in the accompanying figure, how many chromosomes does the cell contain? (Hint: As long as a chromosome consists of two sister chromatids, it is considered to be one chromosome.)
A.2
B.4
C.8
D.1

2.A diploid cell (one which contains two copies of each chromosome) can be designated as 2n, where n (haploid) represents the number of chromosomes in a single set. Is the chromosome number in the cell in the accompanying photo (http://tinypic.com/r/2vry43p/4) diploid or haploid?
A.haploid
B.diploid

3.A diploid cell (one which contains two copies of each chromosome) can be designated as 2n, where n represents the number of chromosomes in a single set. What is the value of n in the cell you have simulated (http://tinypic.com/r/2vry43p/4) at the beginning of Prophase I ?

A.4
B.2
C.1
D.8

4.How many nuclei are present in the model at the end of meiosis I? How many chromosomes are in each nucleus?

A.4 nuclei with 2 chromosomes in each nucleus
B.4 nuclei with 1 chromosome in each nucleus
C.2 nuclei with 2 chromosome in each nucleus
D.2 nuclei with 4 chromosomes in each nucleus

5.How many nuclei are present in the model at the end of meiosis II? How many chromosomes are in each nucleus?

A.4 nuclei with 1 chromosome in each nucleus
B.2 nuclei with 2 chromosome in each nucleus
C.4 nuclei with 2 chromosomes in each nucleus
D.2 nuclei with 4 chromosomes in each nucleus

the fifth is a little odd.
basically 4 nucleas each with 2 chromatids. the 2 chromatids are unlinked
basically could be c
