Answer the following question given this paragraph: Q: What is released when catabolic pathways break down complex molecules? Choices: - hydrogen - oxygen - food - energy A:
energy
Answer the following question given this paragraph: Scientists perform experiments to test their hypotheses because sometimes the nature of natural universe is not obvious. Q: Scientists perform experiments to test their hypotheses because sometimes the nature of natural universe is what? Choices: - become obvious - very obvious - this obvious - not obvious A:
not obvious
Q: Answer the following question given this paragraph: Q: Ammonia, urea, and uric acid are examples of what kind of waste? Choices: - carbonous - sulphurous - oxygenous - nitrogenous A:
A: nitrogenous
Question: Answer the following question given this paragraph: Organisms are organized in the microscopic level from atoms up to cells. The matter is structured in an ordered way. Atoms are arranged into molecules, then into macromolecules, which make up organelles, which work together to form cells. Beyond this, cells are organized in higher levels to form entire multicellular organisms, as shown in Figure below . Cells together form tissues, which make up organs, which are part of organ systems, which work together to form an entire organism. Of course, beyond this, organisms form populations which make up parts of an ecosystem. All of Earth's ecosystems together form the diverse environment that is Earth. Q: What bodily substance is formed from cells, and in turn helps make up organs? Choices: - tendons - muscles - ligaments - tissues A:
Answer: tissues

Answer the following question given this paragraph: Because the organs of the integumentary system are external to the body, you may think of them as little more than "accessories," like clothing or jewelry. But the organs of the integumentary system serve important biological functions. They provide a protective covering for the body and help the body maintain homeostasis. Q: What provides a protective covering for the body and helps maintain homeostasis? Choices: - unadorned system - endorcrine system - lysogenic system - integumentary system A:
**Answer**
integumentary system
Q: Answer the following question given this paragraph: High-energy electrons are released from NADH and FADH 2 , and they move along electron transport chains, like those used in photosynthesis. The electron transport chains are on the inner membrane of the mitochondrion. As the high-energy electrons are transported along the chains, some of their energy is captured. This energy is used to pump hydrogen ions (from NADH and FADH 2 ) across the inner membrane, from the matrix into the intermembrane space. Electron transport in a mitochondrion is shown in Figure below . Q: The electron transport chains are located on the inner membrane of which organelle? Choices: - chloroplast - lysosome - axon - mitochondrion A:
A: mitochondrion
