The correct answer is contractile vacuole.
The contractile vacuole is a water bubble present in the endoplasm of the amoeba. The role of the contractile vacuole is same as the role of the central vacuole in plants.
The contractile vacuole stores the water and the waste material of the cell, along with some mineral and other substance, so, they help in the maintenance of the osmolarity. In case, the walls of the contractile vacuole is damaged, the cell may burst out.

Explanation:
Hershey and chase have concluded that DNA is not protein it was the genetic material.
Explanation:
Hershey and chase said that DNA is not protein it was the genetic material. They took a direct physical approach in finding the genetic material. They both determined that a protective coat was formed around the bacteriophage.
The internal DNA is not a protein, a genetic material. They used label to find it. The lack of 32p labeled DNA remaining in solution after bacteriohages are allowed to absorb the bacteria showed tha DNA was transferred into the bacterial cell.
The radioactive 35s in the solution shows that protein coat protects the DNA before adsorption.
When it comes to the environment and the oceans ecosystem whales help regulate the flow of food by helping to maintain a stable food chain and ensuring that certain animal species do not overpopulate the ocean.
Jeffery Arnett is a physiologist who coined the term "emerging adulthood." This has previously been known as; delayed adulthood, transition age youth, youthhood, and the twixter years. He believes that the period between adolescence and adulthood is when the person reaches adulthood but doesn't have children, have sufficient funds, or have their own home. He believes it starts at 18 and ends around 25 years of age. He thinks this is when people are still looking for love, make money to spend on recreational activities, and trying to develop their own identities. This theory is highly controversial and has been contested by developmental psychologists.
