Shops that use barcode readers may generate receipts with a barcode of the receipt identification number, that enables a salesperson to scan the barcode and quickly retrieve the details of the original transaction, for example if a customer seeks to return or exchange goods or there is some other query.
Both ovaries do not release mature eggs at the same time. Only one egg is, suppose, to be released each month by one of the ovaries, not both. If both ovaries release two matuâ¦re eggs and they are then fertilized, fraternal twins will be conceived.
The ova are larger than sperm and have formed by the time a female is born. Approximately every month, a process of oogenesis matures one ovum to be sent down the Fallopian tube attached to its ovary in anticipation of fertilization. If not fertilized, this egg is flushed out of the system through menstruation.
