Ques: Q: Internal functions are coordinated and regulated so that the internal environment of a living thing is relatively constant, referred to as what? Read this paragraph and choose the correct option from the provided answers: Biology - The Life Science Internal functions are coordinated and regulated so that the internal environment of a living thing is relatively constant, referred to as homeostasis10 . Living things are organized in the microscopic level from atoms up to cells11 . Atoms are arranged into molecules, then into macromolecules12 , which make up organelles13 , which work together to form cells. Beyond this, cells are organized in higher levels to form entire multicellular organisms. Cells together form tissues14 , 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 the Earth's ecosystems together form the diverse environment that is the earth. Example:sub atoms, atoms, molecules, cells, tissues, organs, organ systems, organisms, population, community, eco systems. Choices: - stabilizer - hypothesis - homogenesis - homeostasis A:
Ans: homeostasis

Ques: Q: What property is a measure of the average kinetic energy of molecules? Read this paragraph and choose the correct option from the provided answers: Temperature is a measure of the average kinetic energy of molecules. Consider a mixture of hydrogen and oxygen gas at a certain temperature. Use the formula for kinetic energy to explain why the hydrogen molecules move faster than the oxygen molecules. Then explain why there's no hydrogen in the earth's atmosphere, and why the moon has no atmosphere at all. Choices: - mass - velocity - density - temperature A:
Ans: temperature
