1) Go to search (in Windows charm bar) and type defender and click on it. 2) Once Windows defender is opened, Iâm sure it will be green because it is running currently. Go to âSettingsâ tab and select âAdministratorâ. Remove the tick from âTurn on this appâ to remove windows defender on Windows 8.1. Make sure to save the changes, a warning message will appear as below and Windows defender screen will be changed to red.
Examples of cells that contain this contractile vacuole are amoeba, paramecium, and some types of algae. Some sponges (including amoebocytes, pinacocytes, and choanocytes), singled-celled fungi, and hydra also have contractile vacuoles.
Answered by The Community. Making the world better, one answer at a time. The contractile vacuole should be active when the paramecium is in water. We learned in 6th grade science that a contractile vacuole pumps water out of the cell to prevent it from getting too much water by osmosis.Without working contractile vacuoles, the cell would get too big and might die!he paramecium contains a vacuole called a contractile vauole. By contracting rhythmically, this specialized vacuole pumps excess water out of the cell. the control of water c â¦ ontent within the cell is just one example of an important process known as homeostasis.
