Durable good. A car is a durable good. The gasoline that powers it is a non-durable good, or consumable good. In economics, a durable good or a hard good is a good that does not quickly wear out, or more specifically, one that yields utility over time rather than being completely consumed in one use. Items like bricks could be considered perfectly durable goods because they should theoretically never wear out.
Photosynthetic Protists. These protists belong to a division called Pyrrophyta of algae. They are a well defined group of unicellular, photosynthetic forms. Most of them are flagellated and motile but some forms are non-flagellated.
â¢ Some are digestive and animal-like; others are absorptive and fungus like; others are photosynthetic (plant-like); others are aquatic â¢ Eukaryotic cellsâall eukaryotic cells that do not have the distinctive features needed to be classified as a plant, animal, or fungi cell can often be classified as a protist.
