Explanation:

Answer 2

Answer: Most of this oxygen comes from tiny ocean plants – called phytoplankton – that live near the water's surface and drift with the currents. Like all plants, they photosynthesize – that is, they use sunlight and carbon dioxide to make food. A byproduct of photosynthesis is oxygen.

From a population of red brown orange yellow and green butterflies only the red and green ones survive since they can blend into their environment and reduce predation. Which evolutionary mechanism is involved?

Answers

The evolutionary mechanism involved is genetic drift. Of the butterfly population, the red and green butterflies survived due to their ability to camouflage into their environment while the brown, orange and yellow butterflies did not because of their wing colors.

Final answer:

Cell references in a formula are called values. These references point to specific cells in a spreadsheet and are used for calculations or retrieving data.

Explanation:

Cell references in a formula are called values. These references point to specific cells in a spreadsheet and are used to perform calculations or retrieve data. For example, in the formula =A1+B1, A1 and B1 are cell references that represent the values in those cells.

When creating a formula in a spreadsheet program like Microsoft Excel, you often need to refer to the value in another cell. To do this, you use a cell reference, which allows you to dynamically refer to different cells based on their relative position to the formula. A relative reference adjusts automatically when the formula is copied or moved to a different cell.

For example, if you have a formula in cell B1 that adds the values in cells A1 and A2 together, you would use the relative references A1 and A2 in the formula. If you then copy the formula to cell B2, the references automatically adjust to B1 and B2, so the formula now adds the values in cells A2 and A3.
