Q: Q: Cellular respiration that proceeds in the presence of oxygen is known as what? Read this paragraph and choose the correct option from the provided answers: Then, about 2 or 3 billion years ago, oxygen was gradually added to the atmosphere by early photosynthetic bacteria. After that, living things could use oxygen to break down glucose and make ATP. Today, most organisms make ATP with oxygen. They follow glycolysis with the Krebs cycle and electron transport to make more ATP than by glycolysis alone. Cellular respiration that proceeds in the presence of oxygen is called aerobic respiration . Choices: - digestive respiration - anaerobic respiration - kinetic respiration - aerobic respiration A:
A: aerobic respiration

Q: Q: Under which process do living things with beneficial traits produce more offspring? Read this paragraph and choose the correct option from the provided answers: The other idea is that evolution occurs by natural selection. Natural selection is the process in which living things with beneficial traits produce more offspring. As a result, their traits increase in the population over time. Choices: - migration - differentiation - evolution - natural selection A:
A: natural selection

Q: Q: Momentum is directly related to both mass and? Read this paragraph and choose the correct option from the provided answers: This equation shows that momentum is directly related to both mass and velocity. An object has greater momentum if it has greater mass, greater velocity, or both. For example, a bowling ball has greater momentum than a softball when both are moving at the same velocity because the bowling ball has greater mass. However, a softball moving at a very high velocity say, 100 miles an hour would have greater momentum than a slow-rolling bowling ball. If an object isn't moving at all, it has no momentum. That's because its velocity is zero, and zero times anything is zero. Choices: - mass - intensity - speed - velocity A:
A: velocity

Q: Q: When heat flows into an object, its thermal energy increases and so does its what? Read this paragraph and choose the correct option from the provided answers: When heat flows into an object, its thermal energy increases and so does its temperature. Choices: - matter - speed - color - temperature A:
A: temperature
