<u>Answer:</u>
<em>Meeting current needs while preserving the resource for the future is the objective of sustainable farming. </em>
<u>Explanation:</u>
<em>Sustainable farming uses methods that increase productivity but also understands that the precious natural resources</em> are to be reserved for the future generations also.
Cultivating different types of crops to meet the needs of the <em>population while using non renewable resources in limited amount</em> is the method advocated by sustainable farming. Nutrient replenishment has to be done adequately because once the land is depleted of its <em>nutrients it becomes unsuitable for cultivation. </em>
Over irrigation also produces negative effects by increasing the soil salinity. <em>Productivity increase coupled with resource conservation is the aim of sustainable development. </em>
Dendrochronology, or tree-ring dating, provides absolute dates in two different ways: directly, and by calibrating radiocarbon results. Cross-dating determines the age of undated wood by directly matching ring patterns with trees of known age.
Hope this helps ^^

9. </span><span>the spreading of something more widely.
10. </span><span>In </span>facilitated diffusion<span>, molecules only move with the aid of a protein in the membrane. In </span>simple diffusion<span>, molecules move down the concentration gradient but in </span>facilitated diffusion molecules move up the concentration gradient.
11. <span>a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one
12. </span>Differences<span>: </span>Passive Transport<span> (or Diffusion) moves ions from high concentration to low, using no metabolic energy. </span>Active Transport<span> moves ions from low concentration to high, using metabolic energy in the form of ATP. ... Both use ion channels to move ions across the cell membrane, in or out of the cell</span>
