Based on the information seen in the image above, what is a major difference between viruses and bacteria? a) bacteria can reproduce but viruses cannot. b) bacteria contain dna and viruses contain rna. c) all bacteria are pathogenic, but only some viruses are pathogenic. d) viruses are surrounded by a protein coat; bacteria are surrounded by a cell wall.

D

Explanation:

The cell wall of bacteria is mainly made up of peptidoglycans and lipid molecules while that of viruses is made up of a protein coat called a capsid. The genetic material of bacteria is mainly DNA while that of viruses varies between DNA and RNA (for retroviruses) depending on the type of virus.  Bacteria can replicate outside of host while viruses cannot.

answer:

sequence 1- deletion

                  2- duplication

                  3- insertion

                  4- substitute

                  5- inversion

several tissues working together form an organ, and several organs together make up an organisms.

the group of cell that carries out special jobs are tissue.
