input: OPTIONS:
- intradependence
- realization
- coexistence
- interdependence Now, answer this question: Answer the following question given this paragraph: All living things depend on their environment to supply them with what they need, including food, water, and shelter. Their environment consists of physical factorssuch as soil, air, and temperatureand also of other organisms. An organism is an individual living thing. Many living things interact with other organisms in their environment. In fact, they may need other organisms in order to survive. This is known as interdependence . For example, living things that cannot make their own food must eat other organisms for food. Other interactions between living things include symbiosis and competition. Q: What is the term for when organisms need other organisms to survive? A:
A:
output: interdependence

Answer the following question given this paragraph: Asexual reproduction can be very rapid. This is an advantage for many organisms. It allows these organisms to crowd out other organisms that reproduce more slowly. Bacteria, for example, may divide several times per hour. Under ideal conditions, 100 bacteria can divide to produce millions of bacterial cells in just a few hours. However, most bacteria do not live under ideal conditions. If they did, the entire surface of the planet would soon be covered with them. Instead, their reproduction is kept in check by limited resources, predators, and their own wastes. This is true of most other organisms as well. Q: Bacteria may divide several what an hour? A:

OPTIONS:
- cells
- hosts
- days
- times

Answer: times

Problem: OPTIONS:
- surface species
- fitting species
- species complex
- ring species
Q: Answer the following question given this paragraph: Ring species Ring species demonstrate a version of allopatric speciation. Imagine populations of the species A. Over the geographic range of A there exist a number of subpopulations. These subpopulations (A1 to A5) and (Aa to Ae) have limited regions of overlap with one another but where they overlap they interbreed successfully. But populations A5 and Ae no longer interbreed successfully are these populations separate species? In this case, there is no clear-cut answer, but it is likely that in the link between the various populations will be broken and one or more species may form in the future. Consider the black bear Ursus americanus. Originally distributed across all of North America, its distribution is now much more fragmented. Isolated populations are free to adapt to their own particular environments and migration between populations is limited. Clearly the environment in Florida is different from that in Mexico, Alaska, or Newfoundland. Different environments will favor different adaptations. If, over time, these populations were to come back into contact with one another, they might or might not be able to interbreed successfully - reproductive isolation may occur and one species may become many. Q: Organisms categorized by what species descriptor demonstrate a version of allopatric speciation and have limited regions of overlap with one another, but where they overlap they interbreed successfully?. A:
Answer: ring species

Problem:OPTIONS:
- abandoned
- solid
- segmented
- confined

Answer the following question given this paragraph: Sometimes an aquifer is confined. A confined aquifer is trapped between two impermeable rock layers. Pressure from the rock layer on top forces the water out where the aquifer reaches the ground surface. Water that flows up to the surface naturally is an artesian spring . If people drill a well into a confined aquifer, the water may flow to the surface without assistance. This is an artesian well ( Figure below ). Q: What type of aquifer is trapped between two impermeable rock layers? A:
****
A: confined

Answer the following question given this paragraph: Bioterrorism is the intentional release or spread of agents of disease. The agents may be viruses, bacteria, or toxins produced by bacteria. The agents may spread through the air, food, or water; or they may come into direct contact with the skin. Two of the best known bioterrorism incidents in the U. S. occurred early in this century:. Q: The intentional release or spread of agents of disease is known as what? A:
OPTIONS:
- act of war
- pandemic
- disaster
- bioterrorism
bioterrorism

- shallowest
- youngest
- thickest
- oldest

Answer:
