The diagram shows a bacterial cell. What is the function of the structures labelled X? X codes for very specific features such as antibiotic resistance
X is responsible for movement of the bacterial cell
X is the site of most of the chemical reactions that occur in the bacterial cell
X is responsible for protection of the bacterial cell

Why is the bond angle in a water molecule less than the bond angle of methane? a. the central oxygen atom in water has two lone pairs of electrons, whereas the central carbon atom in methane has no lone pairs. b. the central hydrogen atom in water has one lone pair of electrons, whereas the central carbon atom in methane has two lone pairs. c. the central oxygen atom in water has four lone pairs of electrons, whereas the central carbon atom in methane has only one lone pair. d. the central oxygen atom exerts more repulsive force on surrounding atoms than the central carbon atom in methane does. reset next
