Question

DOES IN AMOEBA BLOOD SUPPLY OXYGEN OR NOT?

Answer 1

★★Hey There★★

Oxygen and Carbon Dioxide, on the other hand, pass through the amoeba cell membrane easily via simple diffusion without active transport or osmotic actions.  
Hope It Helps!!

Answer 2

Amoebas live in water.  Because the inside of their cell is hypertonic to the outside environment (in fresh water), water moves in and out of the cell, through the semi-permeable cell membrane by osmosis controlled by the amoeba's cell biology.  Oxygen and Carbon Dioxide, on the other hand, pass through the amoeba cell membrane easily via simple diffusion without active transport or osmotic actions.  Essentially, the environment inside the cell and outside the cell will come into equilibrium in terms of oxygen concentration, if there is a higher concentration of O2 in the water outside the amoeba, oxygen will diffuse through the cell membrane until the concentration of O2 inside and outside of the cell are equal.


this should really help
