Answer:
Patent ductus arteriosus (PDA) is an extra blood vessel found in babies before birth and just after birth.
Explanation:
The ductus arteriosus is a normal blood vessel that connects two major arteries — the aorta and the pulmonary artery — that carry blood away from the heart.
The lungs are not used while a fetus is in the womb because the baby gets oxygen directly from the mother's placenta. The ductus arteriosus carries blood away from the lungs and sends it directly to the body. When a newborn breathes and begins to use the lungs, the ductus is no longer needed and usually closes by itself during the first 2 days after birth.
If the ductus doesn't close, the result is a patent (meaning "open") ductus arteriosus. The PDA lets oxygen-rich blood (blood high in oxygen) from the aorta mix with oxygen-poor blood (blood low in oxygen) in the pulmonary artery. As a result, too much blood flows into the lungs, which puts a strain on the heart and increases blood pressure in the pulmonary arteries.

Answer: Escherichia coli bacteria cause urinary tract infection in older men
Explanation:
A urinary tracts infection is an infection around the urinary systems like bladder, kidneys and urethra. It is majorly caused by Escherichia coli bacteria in older men. It can be treated by medical professional when diagonised. This infection is common in men of 50 years upward.
Prostrate hypertrophy is an infection of the prostrate gland that cause enlargement of prostrate gland making urine difficult. The disease is age associated, it is found in older men of 50years upward. It is caused by bacteria.
The first thing you need to know is wheather the cell is prokaryotic or eukaryotic. If it does not have nucleus it might be any prokaryotic cell except mycoplasma bacteria. If it is with nucleus, then it might be algae, plants and fungi. The difference between algae, plants and fungi cell wall is in their structure. Plant cell walls containlignin, suberin or cutin, algae possess cell walls made of glycoproteins and polysaccharides and fungi possess cell walls made of the N-acetylglucosamine polymer chitin.
