Water in the soil is held tightly by adhesive forces between the water molecules and the mineral content in soil particles - in the microspores.
Explanation:
While water passes through the macrospores of soil by gravity, water passes through the microspores mainly by cohesion between the water molecules and adhesion between the water molecules and soil minerals. The more surface area for the minerals in the soil (due to finer particle sizes) the higher the water retention rate of the soil. This is why soil with more humus (like silt and clay) retains water more than soils like sand.

A community that runs out of food can import food from other communities, recycle its water and waste.
<h3>What are resources?</h3>
Resources are those things needed by man and other living things to survive.
The most important resources required by living things are food, water and shelter.
A community that runs out of food can import food from other communities, recycle its water and waste.
Therefore, by careful conservation of resources, a community can continue to provide the resources needed by its citizens.

Answer:
mutation in DNA
Explanation:
Mutations are changes in the genetic code that can occur in many ways. Each time a cell divides, say, DNA must be copied into two copies, one copy for each new cell. Although this copying is very precise, it is still not perfect - for about every billion accurately copied databases, one is mistranslated.
Another source is DNA damage, which can occur spontaneously through the normal life of the cell, or through external toxins or negative influences (ultraviolet radiation, for example). Through evolution, cells have developed a very complex system for repairing changes in DNA, but these systems not only have limitations but can sometimes cause additional errors themselves.
Answer:
Both contain genetic material, in the form of DNA and/or RNA. Both of them can replicate, that is, produce more organisms similar to themselves. ... They require a host cell to carry out life processes, such as replication and carrying out genetic instructions, etc. Bacteria are relatively bigger in size than viruses.
Answer:
Temperature
Altitude or Elevation
Moisture or water vapour.
