it is a animal like protists
No, Amoebae is not bacteria.
Some amoebae can cause serious illness if they get into the human body.
I can positively identify sixteen types of amoebae on this specimen plate.
Yes
A major problem for amoebae living in fresh water is the risk of osmotic pressure imbalance. Freshwater environments have lower solute concentrations than the amoebae's internal fluids, leading to water influx into their cells. This can cause the amoebae to swell and potentially burst if they cannot effectively expel the excess water. To counteract this, amoebae often rely on contractile vacuoles to regulate osmotic pressure and maintain cellular integrity.
neither. its a protist
Amoebae are heterotrophic.
A contractile vacuole helps amoebae and paramecium regulate the water content within their cells by periodically expelling excess water to prevent them from bursting due to osmotic pressure. Without a contractile vacuole, these organisms would be vulnerable to cellular damage from fluctuations in hydration levels and could potentially die from osmotic stress.

Amoebae and Paramecia
They are most prominent in freshwater amoebae as marine amoebae are closer to isotonicity with seawater than freshwater.
Amoebae and paramecia require contractile vacuoles for osmoregulation. This is a process which gives these organisms that live in fresh water ability to regulate water balance.
