The positive nuclei of both the H atoms attracts the electrons from each other and are drawn together to lower their potential energy and forming a covalent bond.

When a person redeems/cashes in any savingsbond, they have to pay taxes on the interest they earned on that bond. Instead of cashing in those savingsbonds and having to report all of that interest made and paying taxes on it, people used to be able to buy HH bonds with their other bonds. Because they only converted one bond to another, they did not have to pay the tax on the interest they earned. 'Deferred Interest' is the amount of interest earned on the bonds that were used to purchase your HH bonds, and it is also the amount that you would have to pay taxes on upon redeeming/cashing in your HH bonds. I had difficulty understanding this term as well, until I went to my bank and had it explained to me in plain language. PS. HH bonds are pretty neat. I just received a few that haven't matured yet and am getting them reissued in my name so that I can receive the interest payments as opposed to redeeming them right away for face value and missing out on the interest they could earn. It's not a lot of money, but at least it'll end up paying for the taxes I'd owe on the 778.00 in deferred interest. (That's a lot of tax!) I hope this makes sense!
Hematocrit & Hemoglobin
This is an exception to the octet rule, meaning you will have more than 8 electrons on the Xe in the center.There are 12 electrons to be placed. 4 + 8 = 12. 4 comes from the hydrogens which each give one, and 8 from the Xe because it is in the 8A group.They will be arranged so that all have a single bond to H and that leaves you with 4 electrons still to place to make 12. So they go on the Xe (two pairs).HH -Xe - HH

Homozygous is a description of alleles that are the same (HH,hh): either both dominant or both recessive. Heterozygous is a description of alleles that are different (Hh): one dominant, one recessive.
