Evolution has reduced their size because the structures are no longer used. The human appendix is another example of a vestigial structure. It is a tiny remnant of a once-larger organ. In a distant ancestor, it was needed to digest food. It serves no purpose in humans today. Why do you think structures that are no longer used shrink in size? Why might a full-sized, unused structure reduce an organism's fitness?. Q: What purpose does the appendix serve in humans today? A:
A:
output: none

Answer the following question given this paragraph: Viruses were first described by Dmitri Ivanovsky in 1892. He described a "non-bacterial pathogen" infecting tobacco plants. This was soon followed by the identification of the tobacco mosaic virus by Martinus Beijerinck in 1898. Since then, about 5,000 viruses have been described in detail, although it is believed that there are millions of different types. Viruses are found in almost every ecosystem on Earth, and are the most abundant type of biological entity. Viruses can be classified with a taxonomic structure from order to species. No kingdom classification exists. Viruses, not being made of cells, do not fall into any of the six prokaryotic or eukaryotic kingdoms. Q: What is the most abundant type of biological entity on the earth? A:

OPTIONS:
- bacteria
- reptiles
- insects
- viruses

Answer: viruses

- polyvore
- omnivore
- carnivore
- herbivore

Answer the following question given this paragraph: Different diets require different types of digestive systems. Mammals that eat a carnivorous diet generally have a relatively simple digestive system. Their food consists mainly of proteins and fats that are easily and quickly digested. Herbivorous mammals, on the other hand, tend to have a more complicated digestive system. Complex plant carbohydrates such as cellulose are more difficult to digest. Some herbivores have more than one stomach. The stomachs store and slowly digest plant foods. Q: Because complex plant carbohydrates such as cellulose are more difficult to digest, what animal diet is associated with a complicated digestive system? A:
****
A: herbivore
