Excessive application of fertilizer

The reason for the pond in the center of the park to now be covered with algae is the excessive application of fertilizer.

  • A plant can really die from too much fertilizer, and excess fertilizer can cause toxic algal blooms in lakes and streams that are dangerous to people and their pets as well as other aquatic life.
  • Aquatic "dead zones" are also a result of excessive fertilizer runoff from agricultural and lawn applications in coastal areas.

<h3>What consequences might excessive fertilizer use have?</h3>
  • By increasing the soil's salt concentration, excessive fertilizer changes the soil and might harm beneficial soil microbes.
  • Over-fertilization can result in abrupt plant growth with insufficient roots to provide the plant with enough water and nutrients.

<h3>Can plants bounce back after excessive fertilizing?</h3>
  • A few straightforward procedures can save the majority of over fertilized plants.
  • Remove any fertilizer that is readily visible from the soil and plant, and let water pass through the roots to leach the fertilizer away.
  • After that, take out any damaged foliage and give your plant another meal after about a month.

3.The reduced potential causes hundreds of a)________________________ channels to open on that part of the cell membrane. The de
wlad13 [49]

The reduced potential causes hundreds of <u>voltage-gated sodium</u> channels  to open on that part of the cell membrane. The depolarization of the cell causes more of <u>voltage-gated sodium </u>channels to open in adjacent parts of the cell membrane. This begins the wave of of <u>depolarization</u>  moving down the axon. Depolarization begins at the <u>axon hillock.</u>

Explanation:

When there is no neuron signaling it becomes polarized, termed as resting membrane potential (RMP) at a threshold voltage (around -55 mV), due to the action of the sodium-potassium pump and the potassium leak channels.  

When a change in the RMP occurs, depolarization takes place which causes the voltage-gated sodium channels to open and sodium ions rush into the nerve cell which in turn will increase the voltage threshold to nearly around +40 mV and also charges the neuron positive. This depolarization moves down the axon. This increase in threshold stops the sodium influx and opens the potassium channels to rush the potassium out of the cell.

All these actions decrease the membrane potential leading to a wave of depolarization and going back to resting state. Depolarization begins depending upon the potential gradient at the axon hillock.
