What else can I help you with?
What cell structure prevents lysis in many single celled protists living in a fresh water environment?
Contractile vacuole helps to prevent lysis in many single-celled protists by regulating the water content within the cell. It accumulates excess water and then expels it from the cell, helping to maintain the cell's osmotic balance in a fresh water environment.
Will an obligate halophile burst in fresh water?
Yes, an obligate halophile, which requires high salt concentrations to survive, will likely burst in fresh water due to the sudden change in osmotic pressure causing water to rush into its cell, potentially leading to cell lysis.
Where do most protozoans live?
in water
How do protozoans pump out water?
I'm not sure about other Protozoans but Paramecium, a freshwater ciliate, pumps out excess water with it's Contractile Vacuoles.
Which organism normally uses contractile vacuole to help maintain water balance?
Protists, in general, and the paramecium in particular. These filament surrounded vacuoles, powered by motor proteins and ATP, allow the paramecium to exist in hypotonic conditions by sloughing off the water entering the cell and avoiding cell lysis.
What prefix would you add to lysis to mean separate or splitting using water?
The prefix you add to "lysis" to mean, "separate or splitting using water" is "hydro-." "Hydro-" is the Greek prefix meaning "water."

Are fresh pickles bad when the skin falls of from sitting in water for a day and the water becomes foamy?
The skin falling off of fresh pickle is not normal. It is better to avoid eating them.
What are protozoans that cannot move called?
Protozoans that cannot move are called sessile protozoans. These organisms are typically attached to a substrate and rely on external factors, such as water currents, to bring food to them.
What is the smallest aniamal?
Plankton are very small, microscopic plants and animals. They have little or no power of locomotion and float in surface waters. They are found in fresh and salt water. Planktonic animals include protozoans. While they are often referred to as one-celled animals, they have characteristics found in both plants and animals. Most protozoans cannot be seen without a microscope. There are about 30,000 species of protozoans that have been identified so far!
What happens when marine protozoan is transferred to a fresh water medium?
When a marine protozoan is transferred to a fresh water medium, it may experience osmotic stress due to differences in salt concentrations. This can disrupt its internal balance of water and salts, leading to potential cell damage or death. Additionally, the change in environment could impact its ability to obtain nutrients and interact with other organisms that are specific to marine habitats.
What are a few harmful effects of protozoans?
There are a few harmful effects of protozoans. They can pollute water, reduce the fertility of soil, and destroy the habitats of plants and animals.
