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.
Types of Protists A. Plantlike Protists 1. algae = single-celled and many-celled plantlike protists. a. All algae contain chlorophyll in chloroplasts and make their own food (they are producers). b. The algae may also contain other pigments (colors) in addition to chlorophyll, giving them a color other than green.
