Cells in our intestines play important roles. One function they have is to absorb water that will then be transported to other parts of the body. Their ability to absorb water efficiently is quite important. These cells have villi, or small protrusions in their cells that increase their surface area. What characteristics would improve a cell’s surface to volume ratio? Choose three options.

Increase the surface area but keep the volume relatively the same.
Increase the length of the cell in order to increase both surface area and volume.
Divide a cell into many, increasing the surface area.
Increase the volume of a cell.
Change the shape to one that has a better surface to volume ratio.

Read this summary of a scientific theory: "cells are the most basic structural and functional units of life. all living organisms are made up of one or more cells. all cells that are alive in the world today came from pre-existing cells." which of the following would require this theory to be modified? -a.) a survey finds that a majority of people believe viruses carry out the basic processes of life. -b.) a prominent scientist says she feels strongly that one day the theory will be challenged by life on other planets. -c.) the dna of unicellular and multi-cellular organisms is shown to have many fundamental similarities. -d.) scientific observations show that microscopic organisms living in the deep ocean are not made up of cells.
