Explain two ways in which xylem is modified to carry out its function:

Xylem is adapted to its functions in the following ways: ... It also prevent the walls of xylem from collapsing under pressure caused by transpiration pull. 2. Xylem is made up of water proof, dead cells; this enables it to have high capacity for transporting large quantity of water. The cells that make up the xylem are adapted to their function: They lose their end walls so the xylem forms a continuous, hollow tube. They become strengthened by a substance called lignin . Lignin gives strength and support to the plant.

Explanation:

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.

it should be d) transitional fossils.

they show the gradualism of evolution throughout a period of time
