Answer:
ureters
Explanation:
The ureters are two tubes that drain urine from the kidneys to the bladder. Each ureter is a muscular tube that drains into the bladder. Smooth muscle contractions in the walls of the ureters, over time, send the urine in small spurts into the bladder, the organ where urine is stored before it can be eliminated.
Answer:
3 is cell membrane, 5 is nucleoid and 6 is plasmid.
Explanation:
Structure 3 is cell membrane, structure 5 is nucleoid and structure 6 is plasmid. The structure 4 is cell wall which function is to protect the bacterial cell from outside environment. Bacteria develop resistance to antibiotics due to mutation which change its features. The same type and regular use of antibiotics leads to develop resistance in the bacteria. Plasmids can be used in the production of insulin for diabetics because plasmid has the ability to produce many copies of certain genes.
