The microorganisms found in soil are important because they affect the structure and fertility of soil. Certain bacteria responsible for nitrogen fixation converts nitrogen in the atmosphere, so that it can be used by plants. Because of microbes, nutrients and minerals are made available to plants. Soil with more diverse microbe will result in fewer plant diseases and better crop yield.

The transition from an afferent arteriole to an efferent arteriole occurs in the
timofeeve [1]

Answer: A. glomerulus.  

Explanation:

Each kidney has about 1 million nephrons, the urine-forming unit, and each nephron is made up of a glomerulus (capillaries walls) and renal tubules. The glomerular is constituted by the capillaries walls, which branch out and form a network, covered by the Bowman's capsule that retains the liquid, and begin to form a sequence of tubes.

The blood reaches the kidneys through the renal artery, which branches into the afferent arterioles that attach to the glomerular capillaries (where blood is filtrated), then form the efferent arteriole, which again becomes capillaries - the peritubular capillaries, which surrounds the renal tubules.

In biology, an emergent property is a property possessed by a collective and complex system of constituents, which is lacking in the individual component of the system

Emergent properties are therefore, an important aspect of biological system, for example, a beaker containing graphite (carbon) and ammonium ions in solution contains the same chemicals found in the human brain used to control movement and store memory whereas the chemicals in the beaker are idle.
