In general, the function of the excretory system is, removal of nitrogen waste products from the bloodstream and transport out of the body through urine. It maintains the balance of fluids and electrolytes, control of red blood cells, regulation of blood pressure and also the formation of red bone marrow.
In humans, the excretory system is responsible for removing waste from the body. Metabolic waste is being removed from the blood and an appropriate amount of water nutrients and water and salt are being retained.
In frogs, the excretory system consists of a pair of ureters, kidney pairs, cloaca, and urinary bladder. Frogs take in liquid waste from kidney which removes wastes and then the extra water becomes urine which then it is collected in the urinary bladder through ureters.
The urinary bladder is present in ventral to return then both open into the cloaca.
The correct answer is "C."
mRNA stands for messenger Ribonucleic acid. The role of mRNA is to carry genetic information for the synthesis of protein from the nucleus after transcription.
After the transcription process is over, the mRNA leaves the nucleus and heads to the ribosomes in the cytoplasm where translation of this information takes place.
The ribosomes are the work bench of the cell. They receive the mRNA with its coded information, read it and translate it and with the help of tRNA (transfer RNA), amino acids are fetched from the cytoplasm and linked together to form the exact protein that was coded for on the mRNA.
