Answer:
The correct answer is B. prokaryotes
Explanation:
Archaea and bacteria are the organisms that come under prokaryotes. In Prokaryotes, pro indicate before and karyote indicate nucleus. So these organisms do not have a true membrane-bound nucleus in which they can store their genetic material.
As archaea and bacteria do not have membrane-bound nucleus their genetic material freely moves inside the cytoplasm in their cell. All the prokaryotes are unicellular organisms.
The organisms that have a well membrane-bound organelle like nucleus are called eukaryotes. The genetic material of these organisms are packed in their nucleus. They can be unicellular or multicellular.
Therefore the correct answer is B. prokaryotes.
The urinary system is made up of the kidneys, bladder and ureters (tubes that connect the kidneys to the bladder). The kidneys act as filters removing extra fluid and waste from your blood to make urine. Urine passes from the kidneys into the ureters, which drain into the bladder. When the bladder is full, urine flows out of the body through a tube called the urethra.
The ureters normally enter the bladder at a diagonal angle and have a special one-way valve system that prevents urine from flowing back up the ureters in the direction of the kidneys. If this system doesn’t work, urine can flow back towards the kidneys. This is called vesicoureteric reflux (also known as urinary reflux).
Sometimes vesicoureteric reflux (VUR) can be associated with other 'plumbing' problems in the urinary tract and with small, damaged or malformed kidneys.
So I believe the answer is 1.
