Euglenas are unicellular organisms. They are both self feeder and other feeders. Which statement summarizes the heterotrophic ac
tivities of euglenas? A. They contain chloroplasts with chlorophyll. B. They carry out photosynthesis in sunny places C. They live in water and have tail like structures D. They are colorless and feed on other, smaller cells
The best answer from the list of options is option D (They are colorless and feed on other, smaller cells)
Explanation:
Euglenas have cells that contain chloroplasts, which means they can make their food like plants through photosynthesis, and when it is dark where they can't get sunlight they can also make food by engulfing their prey through the plasma membrane and absorb them. Euglenas are heterotrophic since they call also feed on smaller cells. Their whip-like tail when viewed under the microscope, is colorless. However, the chloroplasts make them appear green and they can also come in red color.
Melanin helps the mouse survive because of the fur color. Its color helps it to blend into its surroundings, making it a lot harder for predators to kill it, as the predators have a harder time seeing the mouse.
Expand. Distilled water is water that has been boiled into vapor and condensed back into liquid in a separate container. Impurities in the original water that do not boil below or near the boiling point of water remain in the original container. Thus, distilled water is a type of purified water.
