Answer the following question given this paragraph: Plants are the primary producers in terrestrial biomes. They make food for themselves and other organisms by photosynthesis. The major plants in a given biome, in turn, help determine the types of animals and other organisms that can live there. Q: What are the primary producers in terrestrial biomes? Choices: - soil - gases - animals - plants A:
plants
Answer the following question given this paragraph: Soil develops over time and forms soil horizons. Soil horizons are different layers of soil with depth. The most weathering occurs in the top layer. This layer is most exposed to weather! It is where fresh water comes into contact with the soil. Each layer lower is weathered just a little bit less than the layer above. As water moves down through the layers, it is able to do less work to change the soil. Q: Which layer of soil experiences the most weathering? Choices: - subsoil - bedrock - humus - top layer A:
top layer
Q: Answer the following question given this paragraph: Muscles are the main organs of the muscular system. Muscles are composed primarily of cells called muscle fibers. A muscle fiber is a very long, thin cell, as you can see in Figure below . It contains multiple nuclei and many mitochondria, which produce ATP for energy. It also contains many organelles called myofibrils. Myofibrils allow muscles to contract, or shorten. Muscle contractions are responsible for virtually all the movements of the body, both inside and out. Q: Muscles are composed mostly of cells called what? Choices: - muscle organelles - muscle filament - muscle polymers - muscle fibers A:
A: muscle fibers
Question: Answer the following question given this paragraph: Q: What does the inner membrane divide into two internal compartments? Choices: - chitin - epidermis - golgi apparatus - mitochondrion A:
Answer: mitochondrion

Answer the following question given this paragraph: Waves are identified by several characteristics. There is a center line where the medium would be if there were no wave, which is sometimes describes as the undisturbed position. The displacement of the medium above this undisturbed position is called a crest and the displacement below the undisturbed position is called a trough . The maximums of the crest and trough are equal and are called the amplitude . The distance between equivalent positions on succeeding waves is called the wavelength . The wavelength could be measured from a crest to the next crest or from a trough to the next trough, and is commonly represented with the Greek letter lambda, . Q: Amplitude describes what about the wave's crest and trough? Choices: - The minimum parts - How frequently the parts occur - The width of the parts - the maximum parts A:
**Answer**
the maximum parts
Q: Answer the following question given this paragraph: In prokaryotes, a combination of activators and repressors determines whether a gene is transcribed. As you know, prokaryotic organisms are fairly simple organisms with much less DNA. Prokaryotic genes are arranged in operons , a region of DNA with a promoter, an operator , and one or more genes that encode proteins needed to perform a certain task. To maintain homeostasis (and survive), the organism must quickly adapt changing environmental conditions. The regulation of transcription plays a key role in this process. Q: In order to survive and maintain what state, an organism must quickly adapt to changing environmental conditions? Choices: - ketosis - acclimatization - regulation - homeostasis A:
A: homeostasis
