Question

which is a single cell animan amoeba or crab​

Answer 1

Amoebas are single-celled organisms that are part of the simplest group of invertebrates. They have a cell membrane, DNA, a nucleus and organelles just like most cells in the human body. The difference is that amoebas can move using their pseudopodia, or “false feet.” They also use pseudopodia to catch and eat food.
