Answer:
Crossing over.
Explanation:
Crossing over may be defined as the phenomena of exchange of the genetic material between the non- sister chromatids of the homologous chromosomes. The crossing over occurs at the pachytene stage.
The crossing over may provide a source of genetic variation as it can create variation in the homologs of paternal and maternal lineage, present within a haploid cell. This crossing over occurs during the process of synapsis.
<u>Answer:</u>
The most appropriate answer option is C. amount of peer review.
<u>Explanation:</u>
Clinical trial is a kind of detailed study or research that is done for a certain test or treatment given to people about how safe and successful that treatment is.
For a clinical trial, the amount of peer review can prove to be a limitation as the trials mostly do not provide appropriate answers to the questions that are asked by the people from the same field.
The symptoms most probably observed in a patient suffering from acute glomerulonephritis are: cola-coloured urine, sudden edema.
Acute glomerulonephritis is a disease affecting the kidneys and it is caused by an active inflammation of the kidney's filters, the glomeruli. Kidneys are composed of nearly one million glomeruli, whose main function is to filter waste products from the blood and pass them into the urine. A severe inflammation in the glomeruli disrupts the filtration of the blood and causes high blood pressure, cola-coloured urine and hematuria (due to the presence of red blood cells in the urine) and fluid retention which causes edema.
On the other hand, nephrolithiasis is the term referring to the formation of kidney stones. A kidney stone that passes through the kidney and the urinary tract can cause many painful symptoms, such as hematuria, ureteral colic pain, costovertebral angle tenderness and nausea and vomiting.
