Q: Cells must also be able to separate their relatively stable interior from what? Read this paragraph and choose the correct option from the provided answers: Cells share the same needs: the need to get energy from their environment, the need to respond to their environment, and the need to reproduce. Cells must also be able to separate their relatively stable interior from the ever-changing external environment. They do this by coordinating many processes that are carried out within organelles, or other cellular structures. Structures that are common to many different cells indicate the common history shared by cell-based life. Examples of these common structures include the components of both the cell (or plasma) membrane and the cytoskeleton, and other structures shown in Figure above . Choices: - their habitat - predators - competition and chaos - the external environment A:
**Answer**
the external environment

Q: Q: What happens to the density of air as the altitude decreases? Read this paragraph and choose the correct option from the provided answers: The pressure of the earth's atmosphere, as with any fluid, increases with the height of the column of air. In the case of earth's atmosphere, there are some complications. The density of the air is not uniform but decreases with altitude. Additionally there is no distinct top surface from which height can be measured. We can, however, calculate the approximate difference in pressure between two altitudes using the equation . The average pressure of the atmosphere at sea level is 1.013 10 5 Pa. This pressure is often expressed as 101.3 kPa. Choices: - multiplies - remains the same - increases - decreases A:
A: decreases
