Coat color in one breed of mice is controlled by incompletely dominant alleles so that yellow and white are homozygous, while cream is heterozygous. Thecross of two cream individuals will produce <span><u>equal numbers of white and yellow mice, with twice as many creams as the other two colors.</u></span>
Answer:
I really just want to say B because they just suppress the immune system, but they are used to treat autoimmune diseases, but the drug itself doesn't replace anything
1. PbO is a possible formula units, since O has charge of 2- and Pb can have a charge of 2+ or 4+, if it uses the 2+ ion, the charges will balance out to form PbO. Li+ and B(3-) would have Li3B, Al(3+) and Pb(2+) are both positive charges and would not balance out, Cl- and O(2-) are both negative charges and would not balance out.
2. Iodine is a halogen, so it has a charge of -1. Calcium is an alkaline earth metal in Group 2, so it has a charge of 2+. Therefore, if they were to form a formula unit, the resultant would be CaI2 (2 iodine atoms of 1- charge are needed to balance out the 2+ charge on the calcium atom).
3. Strontium is an alkaline earth metal with a charge of 2+, while phosphorus has a charge of 3-. Therefore, to balance the charges out, we would need 3 atoms of strontium and 2 atoms of phosphorus. This would give the formula unit of Sr3P2.

From right to left.
1) Cytokinesis is almost
finished, so it’s the end of Telophase
2) The chromatids have just
split up and are migrating to each pole, so it’s Anaphase
3) All chromosomes are in the
equatorial plane, so it’s the end of Metaphase
4) The chromosomes are in the
poles and cytokinesis has just started, so it’s the beginning of Telophase
5) The spindle apparatus is
complete and the chromosomes are moving to the equatorial plate, so it’s the
beginning of Metaphase
6) The spindle apparatus is forming,
so it’s Prophase
If you want to put them in
chronological order, it’s like this:
6-5-3-2-4-1
