Answer & Explanation:

The first important part to consider is the actual definition of species. There are many, depending on the field. Essentially two organisms belong to the same species if they can <u>mate, cross and the breeding is viable.</u> This means that, if they do mate and actually give birth, the baby must be able to also mate and breed. Hybrids, for example, cannot breed and that's because the parents did not belong to the same species, causing that the breeding is infertile. Recently molecular studies have been able to recognize organisms from the same species with their genetic similarities or differences.

Bond [772]

The doctor or nurse will ask a urine sample of the daughter for lab analysis to check for bacteria, red blood cells or white blood cells. Sometimes after the urine lab analysis it will be followed by a urine culture. This test will tell the doctor what kinds of bacteria are the source of the infection and which treatment or medicine will work the most. If the daughter is having frequent infections or low grade fever that the doctor concludes that it may have been caused by an abnormality in the urinary tract, she may have a magnetic resonance imaging (MRI), a computerized tomography (CT) scan or ultrasound. The doctor or nurse may use a contrast dye as well to highlight structures in the child’s urinary tract. Moreover, the doctor may conduct a cystoscopy, using a long, thin tube with a lens (cystoscope) to see inside the child’s bladder and urethra if the child will have recurrent UTIs.
