Kingdoms are divided into phyla and each phylum is divided into classes.
2) The given statement is true. Shade A.
Bacterial spores can survive treatment that would kill almost any other organism, because bacterial spore are resistent to many things.
3) The given statement is False.Shade - B
Penicillin doesnot act against bacteria by suppressing their energy metabolism.It act by disrdisrupting cell wall.
4) The given statement is False.Shade - B
