NERVOUS SYSTEM HAVE ELONGATED CELLS CALLED NEURONS WHICH HELP IN INITIATING AND TRANSMITTING NERVE IMPULSES TO VARIOUS BODY PARTS. IT HAS THREE PARTS CYTON,AXON,DENDRON IN AN ORDER OF DENDRITES(ELONGATED FINE PROCESS OF DENDRONS)-- CYTON---AXON SO THE CONNECTION BETWEEN PRECEDING AXON AND FORWARDING DENDRITE IS SYNAPSE.
MICROORGANISMS DECAY BIOGREDABLE WASTES SO THEY INCREASE SOIL FERTILITY.
Microorganisms as such don't involve directly in maintaining soil fertility so as to provide adequate nutrient with suitable proportions. however these microorganisms make plant nutrients available for plant uptake considering many more mechanisms. Some of the mucilages and other secretions involve in the process of release of micro and macro nutrients from the clay surface making it more vulnerable in soil solution form which is the immediate form for uptake by roots... microorganisms take part in mineralisation processes whereby non available form is converted in available forms.. polysaccharide yielded by these microorganisms has tremendous role in binding sand silt and clay thereby making stable aggregation resulting in good physical condition of the soil..by this, there will be good contact and coordination of a nutrient with medium that is soil
The main difference between oviparous and viviparous animals is that oviparous animals do not undergo any embryonic development inside the mother whereas viviparous animals develop into a young animal inside the mother. ...
