Anyone here or a signifigant other of someone here have a balanced translocation and have children?? AKA a chomosome rearrangement. If so, please share your story with me. My husband and I are planning to start a family but are concerned because he has a balanced translocation (he himself is perfectly fine and normal except for the fact that he carries the gene for it.) and we know there can be difficulties due to it. We could use any help or advise from someone who has experiance with this, we dont know where to start. Thanks in advance!!

The Readers Digest states,"One fifth of the world's fresh water plunges over Niagra Falls". I find this very hard to believe, considering the Amazon, Mississippi, Columbia. Nile and thousands of others I don't even know the names of. Where would I find the facts??

Hi
I never was good at mathematics. I can understand core principles "by overview" (what the idea is behind the approach to solve a math-question).
But when you ask me to calculate a difficult math-question I have a hard time understanding what I must do next to solve it.
My main issues are with dividing, ratios and percentage.
I dunno why this is. My father and mother both are great with math.

Whenever I get difficult questions that I dont seem to understand. and I cant solve it. I just turn lazy and I just get this sort of sleepy ffeeling in my head,
as if it is just too much for me (lol)

Now I undertsand math is very important.
Most college educations require math to some degree.
So My question is:
Do you know any tricks or do you have any suggestions (any)
that could help me improve my math-skills?
Do I have to go back to like 7th grade and redo all them books?

I really dont know how to overcome this.

I am doing a lab. I have two test tubes filled with 10mL of tap water. The next step is "Mass 0.llg of sodium carbonate and 0.25g of copper sulfate, and add each to the proper test tubes." My scale will not allow me to measure in that deatale. What am I supposed to do to make it measurable? By the way this is a lab on Stoichiometry. I am measuring the precipitate. I would ask my teacher but am home schooled.
