Advantages of fertilisers:
1. They are nutrient specific
2.They are readily absorbed by plants since they are soluble in water.
3.They are compact and hence easy to transport, store and handle
4.They enhance the metabolism.
Disadvantages of fertilisers:
1.They get washed away by water easily and cause pollution.
2.They harm the microbes present in soil.
3. They reduce soil fertility.
4.They are expensive.
5.They provide only short term benefits.
6. They change the nature of soil, making it either too acidic or too alkaline.
I search it on google and I found this can you mark as brainliest answer please
An INHIBITORY Signal is sent between neurons when (A)Na+ rushes into the neuron.
Explanation:
- When one spot of membrane supports an action potential, lots of \text {Na}^+Na+start text, N, a, end text, start superscript, plus, end superscript ions hurry into the cell by that spot.
- These ions radiated out sideways into the cell and can depolarize a nearby spot of membrane, stimulating the hole of voltage-gated sodium channels and causing the nearby spot to support its action potential.
- The action potential can only move in one direction – from the cell body towards the axon terminal – because a spot of membrane that has just experienced one action potential is in a “refractory period” and cannot withstand another.
The youngest rock is found near mid-ocean ridges since a new rock is formed near the mid-oceanic ridge as oceanic plates diverge or separate from each other. Hot rocks rising from the asthenosphere melt from decompression as they rise, filling the fault and forming new basaltic oceanic <span>crust. As new crust is added, older crust is pushed away. Hope this answer helps.</span>
