2. what does a surface area/volume ratio of 6: 1 mean for the cell’s ability to get the materials it needs that move across its surface?

Answer;

-A surface area/volume ratio of 6:1 means the cell's ability to get materials it needs that move across its surface is very efficient.

-Increased surface area to volume ratio makes diffusion and osmosis much more effective. Cellular concentrations of ions, nutrients, salts, etc can occur much more quickly and efficiently.

Explanation;

-The surface area to volume ratio of a cell is the relationship between two measurements.That is; the ratio of Surface area to volume. It shows the comparison between the size of the outside of a cell and the amount inside. Small or thin cells have a large surface area compared to the volume.

correct answer: understand the different control methods available

integrated pest management is an strategy that is based on the ecosystem and try to prevent the pest and the damage caused by them by applying combination of technique like habitat manipulation, biological control and use of resistant varieties.

the main aim of the integrated pest management is not to completely eliminate the pest but to strengthen the ecosystem so that conditions are favorable for plants and unfavorable for pests.
