Certain cells, such as those along the digestive tract, need to absorb a lot of materials. What unique features do you notice about the shape of these cells? How might this improve their ability to absorb materials?

Cells are the functional and structural units of life. The cells make up the tissues, organs, and organ systems. The cells based on the shapes and properties differ in their functions.

In the given image, the special features of the cells of the digestive tract are microvilli.

Villi are the finger-like projections present on the intestinal wall. These will function in increasing the surface area to enhance the digestion process.

On the surface of the villi, numerous micro-hair-like projections are presently known as microvilli. The microvilli are the help in increasing the surface area of the villi.

These finger-like projections create a wave or brushing-like movement for the increased absorption and surface area.

Therefore, the given image is of microvilli that helps in increasing the surface area.

the reason the two sea urchins don't compete with each other for food, resources, etc. is because the urchins have adapted to the environment but they have also adapted to each other. this is most likely because the genes of the sea urchins.
