How do single celled organisms exchange nutrients and wastes with their environment?
by allowing them to diffuse through the cell membrane
What is a selective barrier regulating the passage of materials into and out of the cell?
In a plant cell, this selective barrier is known as the cell membrane but also a plant cell has a cell wall. The cell membrane is semi permeable allowing only certain materials so the cell membrane allows in materials and the cell wall ''digests it''. While in a plant cell does not have a cell wall only a cell membrane.It is the cell membrane that acts as its selective barrier.
How do farmers destroyes the soil structure?
By mechanically disturbing it, by removing the nutrients from it and by allowing it to be eroded.
How does selective media works in microbiology?
Selective media, is made up of certain nutrients that can either inhibit or enhance the growth of certain bacteria and or fungus. This is why they call it selective media, it is generally only selective for one kind of bacteria or does certain things when that bacteria or fungus is present.

What cell organelle is responsible for allowing nutrients and water in and out of the cell?
The cell membrane, also known as the plasma membrane, is responsible for allowing nutrients and water in and out of the cell. It acts as a selectively permeable barrier that regulates the passage of substances, allowing essential molecules to enter the cell while preventing harmful substances from entering.
What are the two main jobs of the skeleton?

Flooding provided nutrients to the desert soil allowing the Egyptians to grow crops.
Feature the plasma membrane that maintains the cell's homeostasis by allowing some molecules into the cell while keeping others out?
Selective permeability otherwise known as semipermeable membrane.
