Answer the following question given this paragraph: Terrestrial ecosystems, also known for their diversity, are grouped into large categories called biomes. A biome is a largescale community of organisms, primarily defined on land by the dominant plant types that exist in geographic regions of the planet with similar climatic conditions. Examples of biomes include tropical rainforests, savannas, deserts, grasslands, temperate forests, and tundras. Grouping these ecosystems into just a few biome categories obscures the great diversity of the individual ecosystems within them. For example, the saguaro cacti (Carnegiea gigantean) and other plant life in the Sonoran Desert, in the United States, are relatively diverse compared with the desolate rocky desert of Boa Vista, an island off the coast of Western Africa (Figure 20.3). Q: Terrestrial ecosystems, also known for their diversity, are grouped into large categories called what? Choices: - bisomes - monomes - substrates - biomes A:
biomes

Answer the following question given this paragraph: The phagocytes that are part of the body's second line of defense attack any pathogens they encounter. They provide a general defense. Some white blood cells attack only certain pathogens. They provide a specific defense. Q: The phagocytes that are part of the body's second line of defense attack any of what that they encounter? Choices: - viruses - vaccines - parasites - pathogens A:
(Answer)
pathogens
Ques: Answer the following question given this paragraph: The electron loss and gain is easy to see in a reaction in which ions are formed. However, in many reactions, no such electron transfer occurs. In a molecular compound, electrons are shared between atoms in a type of bond called a covalent bond. Yet it is still common for reactions involving molecular compounds to still be classified as redox reactions. Q: In a molecular compound, electrons are shared between atoms in which type of bond? Choices: - Ionic - deformation - corrosion - covalent A:
Ans: covalent

pollen
Ques:Answer the following question given this paragraph: The use of electric current to encode information is called electronics. Electronic signals may be digital or analog signals. Both types of signals encode information by changing the voltage of an electric current, but they do so in different ways. Q: What do we call use of electric current to encode information? Choices: - products - metals - ferious - electronics A:

Ans:electronics
Answer the following question given this paragraph: Q: What fibres are seen in some vertebrates that twitch at rates far faster than any human muscle? Choices: - fast oxidative fibres - slow twitch fibres - fast glycolytic fibres - skeletal muscle fibers A:
skeletal muscle fibers
