- Animal cells do not have vacoule - actually animal cell like amoeba/ paramecium have small vacoule
- A log, being very heavy and sinks in water - log heavy but the volume is big too. so log not sink in water... consider the formula of density -------> when mass divide the volume we get the density. density of log is low.....below the density of water. log can float in water.
- A population is a group of all the organism present in a habitat - wrong. population is a group of same species in a habitat
- parasites usually kill their hosts - parasite not kill their hosts....parasites continue to live on/in the host to get benefits from the living host. predator kill for food
