Question

Read the following sentences from the text.
“Devreotes and other biologists have learned that Dictyostelia move by first stretching out a piece of themselves, sort of like a little foot. This "pseudopod" then senses its environment for the highest concentration of a local chemical attractant—for the amoebae this is often food, and for the white blood cell, it is the scent of an invader. The pseudopod, followed by the entire cell, moves toward the attractant by alternately sticking and unsticking to the surface along which it moves…”

What conclusion can you draw from this evidence? Audio


It is very difficult for Dictyostelia to sense anything in their environment because they are single-celled organisms. Audio

Dictyostelia and white blood cells are both able to sense and move through their environment using pseudopods. Audio

Dictyostelia are unable to move any part of themselves without help from white blood cells. Audio

Amoebae like Dictyostelia are only able to locate food sources on very sticky surfaces. Audio

Answer 1

The most accurate conclusion that can be drawn from the provided evidence is:

**Dictyostelia and white blood cells are both able to sense and move through their environment using pseudopods.**

This conclusion is supported by the text, which describes how both Dictyostelia and white blood cells use pseudopods to sense their environment and move toward chemical attractants.
