The cell membrane allows the transportation of materials in and out of plant cells, although the cell wall is also key for these processes.
What is the cell wall?The cell wall is a rigid structure located outside the plant cell that protect it against friction and osmotic stress.
The cell wall is also required to transport substances in and out of the plant cell by pores present in this structure.
Moreover, the cell membrane is a physical barrier that allows the interchange of nutrients and waste materials between the cell and its surrounding environment.

Answer:
Radiocarbon dating
Explanation:
Radiocarbon dating is a technique for determining the age of carbon-based materials derived from live beings. By measuring the quantity of carbon-14 in a sample and comparing it to an internationally accepted reference standard, an age may be determined. Radiocarbon dating is based on the basic principle that all living organisms absorb carbon from the atmosphere and food sources around them, including a small quantity of naturally radioactive carbon-14. When a plant or animal dies, it stops absorbing carbon, but the radioactive carbon it has stored decays.

Answer:
Humans are gradually altering the climate and the earth's temperature through burning fossil fuels, destroying forests, and rearing animals.
Explanation:
This significantly increases the amount of greenhouse gases already present in the atmosphere, increasing the greenhouse effect and contributing to global warming.
