Shannon is making d Venn diagram to organize the characteristics of cell walls and cell membranes Which pair of characteristics both belong in the two areas of the Venn diagram that do not intersect? helps with communication; contains mostly cellulose contains mostly cellulose; forms the outer layer of animal cells is found in plant cells; is found in animal cells is semipermeable; found in animal cells

## Step 1<br />The problem is asking us to identify the pair of characteristics that are unique to cell walls and cell membranes and do not overlap. This means we need to find the characteristics that are unique to each of these structures.<br /><br />## Step 2<br />Cell walls are unique to plant cells and are primarily composed of cellulose. They provide structural support to the cell. Cell membranes, on the other hand, are found in both plant and animal cells and are involved in various functions such as communication and the formation of the outer layer of animal cells.<br /><br />## Step 3<br />Looking at the options, we can see that the pair "helps with communication; contains mostly cellulose" includes a characteristic of cell membranes (communication) and a characteristic of cell walls (cellulose). However, the characteristic of communication is not unique to cell membranes as it is also a function of cell membranes.<br /><br />## Step 4<br />The pair "contains mostly cellulose; forms the outer layer of animal cells" is incorrect because cell walls do not form the outer layer of animal cells.<br /><br />## Step 5<br />The pair "is found in plant cells; is found in animal cells" is incorrect because cell walls are not found in animal cells.<br /><br />## Step 6<br />The pair "is semipermeable; found in animal cells" is incorrect because cell membranes are semipermeable, but cell walls are not.
