Life on our planet is made up of an incredible variety of carbon molecules, and, in essence, life processes are carbon chemistry. Conversely, the carbon cycle, which can be viewed as the movement of carbon atoms through various places of storage on Earth, called reservoirs, is intimately tied to life processes.xamples of reservoirs are the ocean, the atmosphere, the biosphere, the soil carbon, the carbonate sediments, and the organic carbon sediments.. The fluxes between them describe the rate at which atoms move from one reservoir into another.
A loan agreement is: 1  A borrower's written promise to repay a sum of money, or principal, to the lender.  A document that outlines the terms of a loan, including a repayment plan, between a lender and a borrower.
Notes receivable are also called promissory notes. That is, they require the debtor to pay the promised amount at a definite time or on demand. One making the promise (i.e., debtor) is called the maker, while one to whom the note is payable (i.e., the creditor) is called the payee. Due (maturity) date is the date when the note receivable is to be paid. As mentioned earlier, notes receivable require an interest payment by the maker of the note. Notes receivable usually state the annual interest rate, regardless of the term of the note. Interest can be paid monthly, quarterly, semiannually, or annually. Short-term notes receivable (i.e., less than one year) usually require interest payment at the maturity date.
