Question: Answer the following question given this paragraph: Chlamydia is the most common STI in the United States. As shown in the graph in Figure below , females are much more likely than males to develop chlamydia. Like most STIs, rates of chlamydia are highest in teens and young adults. Q: Which is the most common sti (sexually transmitted infection) in the united states? A:
OPTIONS:
- AIDS
- giardia
- syphilis
- chlamydia
Answer: chlamydia

input with options: Answer the following question given this paragraph: 15.11 Amines: Structures and Names LEARNING OBJECTIVES Identify the general structure for an amine. Identify the functional group for amines. Determine the structural feature that classifies amines as primary, secondary, or tertiary. Use nomenclature systems to name amines. Amines are classified according to the number of carbon atoms bonded directly to the nitrogen atom. A primary (1) amine has one alkyl (or aryl) group on the nitrogen atom, a secondary (2) amine has two, and a tertiary (3) amine has three (http://catalog. flatworldknowledge. com/bookhub/reader/2547. Q: Amines are classified according to the number of carbon atoms bonded directly to what atom? A:
OPTIONS:
- helium
- oxygen
- hydrogen
- nitrogen
output: nitrogen

Answer the following question given this paragraph: inviability because the hybrid organisms simply are not viable. In another postzygotic situation, reproduction leads to the birth and growth of a hybrid that is sterile and unable to reproduce offspring of their own; this is called hybrid sterility. Habitat Influence on Speciation Sympatric speciation may also take place in ways other than polyploidy. For example, consider a species of fish that lives in a lake. As the population grows, competition for food also grows. Under pressure to find food, suppose that a group of these fish had the genetic flexibility to discover and feed off another resource that was unused by the other fish. What if this new food source was found at a different depth of the lake? Over time, those feeding on the second food source would interact more with each other than the other fish; therefore, they would breed together as well. Offspring of these fish would likely behave as their parents: feeding and living in the same area and keeping separate from the original population. If this group of fish continued to remain separate from the first population, eventually sympatric speciation might occur as more genetic differences accumulated between them. This scenario does play out in nature, as do others that lead to reproductive isolation. One such place is Lake Victoria in Africa, famous for its sympatric speciation of cichlid fish. Researchers have found hundreds of sympatric speciation events in these fish, which have not only happened in great number, but also over a short period of time. Figure 18.21 shows this type of speciation among a cichlid fish population in Nicaragua. In this locale, two types of cichlids live in the same geographic location but have come to have different morphologies that allow them to eat various food sources. Q: As the population grows, competition for food does what? A:

OPTIONS:
- stays the same
- decreases
- stagnates
- grows

Answer: grows

A:
contour lines
