Maximum Credit. As of 2012, the maximum credit for dependent care expenses was $2,100 a year. However, the maximum was available only to taxpayers who had paid for care for more than one dependent, had at least $6,000 in dependent care expenses during the year, and had an adjusted gross income of $15,000 or less.A look at how the credit is calculated explains where this $2,100 figure comes from.owever, the maximum was available only to taxpayers who had paid for care for more than one dependent, had at least $6,000 in dependent care expenses during the year, and had an adjusted gross income of $15,000 or less.

We breathe in oxygen and some of this carbon dioxide. When we exhale, we breathe out less oxygen but more carbon dioxide than we inhale. Paul Roberts, Lake Cathie. The carbon we breathe out as carbon dioxide comes from the carbon in the food we eat. The carbohydrates, fat and proteins we consume and digest are eventually converted by a number of different biochemical pathways in the body to glucose (C6H12O6).
How does the oxygen that we breathe in kill us? I know that oxygen (not pure) that we breathe in is one of the reasons why we die because it's corrosif but could somebody please explain this to me i don't understand how. How could i explain this to somebody else? Update: Pure oxygen kills us. The air is made up of 20% oxygen. I thought that oxygen attacked your cell membrane. I've been doing some research but i'm not sure. I would imagine that it would because there is still oxygen in the air we breathe so basically it's mother nature's way of killing us off.
