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.
Answer:
A
. the fertilized egg and the cells produced by the first few cell divisions
Explanation:
Totipotent cells are those cells in developmental stage of multicellular organisms which can give rise to any part of the organism. It can give rise to both the placenta and the embryo.
After the fertilization, the cells produced in first few divisions are totipotent. This stage is also called as morulla stage. Once blastocyst stage is reached, totipotency is lost. All the cells of blastocyst are not totipotent. The inner cell mass of blastocyst is pluripotent which means it can give rise to the entire embryo except placenta. The trophoblast layer of blastocyst can only produce placenta.
Climate change refers to the variation in the statistical distribution pattern of weather when that variation endures for an elongated time duration. The change in climate is a result of various elements like biotic procedures, changes in solar radiation received by Earth, plate tectonics, and others.
The changes in Earth's orbit, volcanic eruptions, combustion of fossil fuels, and meteorite impact, all donate directly or indirectly to climate change by changing the amount of solar radiation that reaches Earth. Hence, the correct answer is option B.
