Answer:

Cell membrane is considered as boundary of the cell.

Explanation:

Cell membrane is the boundary of the cell which is selectively permeable that allows the micro-nutrients, water and gases like oxygen and carbondioxide etc through the process of diffusion. When the water goes inside due to diffusion it is the indicator that there is less quantity of water present inside the cell as compared to the external environment, this phenomena is called hypertonic.

Region of the World                             Percentage    Value in Metric tons
North America                                          17                  23,332,500
Asia                                                          52                  71,370,000
Africa                                                          3                    4,117,500
Europe                                                     18                  24,705,000
Latin America and the Caribbean              8                  10,980,000
Oceania                                                  <u>   2</u>                <u>    2,745,000</u>
                                                               100                137,250,000

We multiply the 137.25 million metric tons by its percentage to get its equivalent value in metric tons.

Asia uses 71.37 million metric tons.

In making the bar graph, The vertical line will be the percentage and the horizontal line will be the region. Bars of each region should have different colors for easy identification. Spaces between bars should be present, so that the bar graph will not be confused with the histogram.

What is the flow of molecules in passive transport?
Vilka [71]

Answer:

The movement of molecules across a membrane without the input of energy is known as passive transport. When energy (ATP) is needed, the movement is known as active transport. Active transport moves molecules against their concentration gradient, from an area of low concentration to an area of high concentration.
