Answer the following question given this paragraph: Ecology is the study of ecosystems. An ecosystem consists of all the living and nonliving components of the habitat. Whereas nutrients and certain elements are recycled through ecosystems, energy moves in just one direction. Many interactions among species within an ecosystem are centered around the flow of energy. The formation of ecosystems, from new land to current habitats, is usually based on the pioneer species, and these species are able to live in an area due to the nonliving factors, such as the climate, the soil and the amount of rainfall, of that area. The populations within an ecosystem also determine the stability of the system. Recent tremendous increases in the human population have raised many important ecological issues. Q: What is the study of ecosystems? Choices: - physics - botany - geology - ecology A:
ecology
Answer the following question given this paragraph: The gene theory is the idea that the characteristics of living organisms are controlled by genes, which are passed from parents to their offspring. A gene is a segment of DNA that has the instructions to encode a protein. Genes are located on larger structures, called chromosomes , that are found inside every cell. Chromosomes, in turn, contain large molecules known as DNA (deoxyribonucleic acid). Molecules of DNA are encoded with instructions that tell cells what to do.

Q: Which theory is the idea that the characteristics of living organisms are controlled by genes, which are passed from parents to their offspring? Choices: - species theory - evolution theory - fossil theory - gene theory A:
gene theory
Q: Answer the following question given this paragraph: Some mollusks, such as oysters and scallops, are important food sources. Q: What type of creature is a scallop? Choices: - insect - vertabrate - algae - mollusk A:
A: mollusk
Question: Answer the following question given this paragraph: The chloroplast is the site of photosynthesis. Part of the photosynthesis reactions occur in an internal membrane within the organelle. Many of the pigments and other molecules necessary for photosynthesis are embedded within these internal membranes, The chloroplast contains many of these internal membranes, allowing numerous photosynthetic reactions to occur simultaneously, and making photosynthesis very efficient. These internal membranes stack on top of each other, just like a stack of pancakes. Q: Where is the site of photosynthesis? Choices: - another chloroplast - the chloroburst - the organism - the chloroplast A:
Answer: the chloroplast

Answer the following question given this paragraph: events in angiosperms are known as double fertilization (Figure 32.18). After fertilization is complete, no other sperm can enter. The fertilized ovule forms the seed, whereas the tissues of the ovary become the fruit, usually enveloping the seed. Q: After fertilization is complete, no other sperm can enter. the fertilized ovule forms the seed, whereas the tissues of the ovary become this? Choices: - plant - wheat - vegetables - fruit A:
**Answer**
fruit

Answer the following question given this paragraph: A tornado only strikes a small area. But it can destroy everything in its path. Most injuries and deaths from tornadoes are caused by flying debris ( Figure below ). In the United States, an average of 90 people are killed by tornadoes each year. The most violent two percent of tornadoes account for 70% of the deaths by tornadoes. Q: What consequence of a tornado is responsible for most injuries and deaths? Choices: - catching debris - touring debris - falling debris - flying debris A:
**Answer**
flying debris
