Q: Answer the following question given this paragraph: Erosion moves sediments after they have formed. The sediments are transported away from the place where they form. There are several agents of erosion. Flowing water moves and deposits sediments. Water erodes far more material than any other erosional agent. Wind is important as an agent of erosion. This is especially true in arid climates. Ice, in glaciers, can erode enormous quantities of sediments. Gravity as a force of erosion pulls material downhill. Q: What moves sediments after they have formed? Choices: - photosynthesis - migration - perspiration - erosion A:
A: erosion

Q: Answer the following question given this paragraph: In the Cell Cycle: Cancer (Advanced) concept, cancer is described as developing due to unregulated cell division. That is, cancer is a disease characterized by a population of cells that grow and divide without respect to normal limits. These cancerous cells invade and destroy adjacent tissues, and they may spread throughout the body. The process by which normal cells are transformed into cancer cells is known as carcinogenesis . This process is also known as oncogenesis or tumorigenesis. Oncogenes are mutated genes involved in the development of cancer. Q: Cancer develops when what process is unregulated? Choices: - metabolism - meiosis - cellular respiration - cell division A:
A: cell division

Q: Answer the following question given this paragraph: Q: Phytochromes regulate many plant responses to what? Choices: - heat - gravity - oxygen - light A:
A: light

Q: Answer the following question given this paragraph: The smallest piece of an element that maintains the identity of that element is called an atom. Individual atoms are extremely small. It would take about fifty million atoms in a row to make a line that is 1 cm long. The period at the end of a printed sentence has several million atoms in it. Atoms are so small that it is difficult to believe that all matter is made from atomsbut it is. The concept that atoms play a fundamental role in chemistry is formalized by the modern atomic theory, first stated by John Dalton, an English scientist, in 1808. It consists of three parts: 1. Q: An atom is the smallest unit of what that maintains the identity of the latter? Choices: - mixture - organism - cell - element A:
A: element
