input: OPTIONS:
- complete exclusion
- produce exclusion
- tough exclusion
- competitive exclusion Now, answer this question: Answer the following question given this paragraph: Competitive Exclusion Principle Resources are often limited within a habitat and multiple species may compete to obtain them. All species have an ecological niche in the ecosystem, which describes how they acquire the resources they need and how they interact with other species in the community. The competitive exclusion principle states that two species cannot occupy the same niche in a habitat. In other words, different species cannot coexist in a community if they are competing for all the same resources. An example of this principle is shown in Figure 45.24, with two protozoan species, Paramecium aurelia and Paramecium caudatum. When grown individually in the laboratory, they both thrive. But when they are placed together in the same test tube (habitat), P. aurelia outcompetes P. caudatum for food, leading to the latter's eventual extinction. Q: Which principle states that two species cannot occupy the same niche in a habitat? A:
A:
output: competitive exclusion

Problem:OPTIONS:

Answer the following question given this paragraph: The Golgi apparatus is a large organelle that sends proteins and lipids where they need to go. It's like a post office. It receives molecules from the endoplasmic reticulum. It packages and labels the molecules. Then it sends them where they are needed. Some molecules are sent to different parts of the cell. Others are sent to the cell membrane for transport out of the cell. Small bits of membrane pinch off the Golgi apparatus to enclose and transport the proteins and lipids. You can see a Golgi apparatus at work in this animation:. Q: Which organelle is often compared to a post office, moving proteins and lipids to where they need to go? A:
****
A: the golgi apparatus

Answer the following question given this paragraph: Sympatric speciation occurs when groups from the same species stop mating because of something other than physical or geographic separation. The behavior of two groups that live in the same region is an example of such separation. The separation may be caused by different mating seasons, for example. Sympatric speciation is more difficult to identify. Q: What occurs when groups from the same species stop mating because of something other than physical or geographic separation? A:
OPTIONS:
- extinction
- complementary speciation
- invasive speciation
- sympatric speciation
sympatric speciation

Answer the following question given this paragraph: Parasitic roundworms may have plant, vertebrate, or invertebrate hosts. Several species have human hosts. For example, hookworms, like the one in Figure below , are human parasites. They infect the human intestine. They are named for the hooks they use to grab onto the host's tissues. Hookworm larvae enter the host through the skin. They migrate to the intestine, where they mature into adults. Adults lay eggs, which pass out of the host in feces. Then the cycle repeats. Q: Through which organ do hookworm larvae enter the human body? A:
OPTIONS:
- through the lungs
- through the rectum
- through the mouth
- through the skin

Answer:
through the skin
