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.

Active and passive humoral immunity are both mechanisms of adaptive immunity that use antibodies. true false
dolphi86 [110]

Active and passive humoral immunity are both mechanisms of adaptive immunity that use antibodies. yes this is true

  • Our adaptive immune system protects us from infection-related mortality. An new-born born with a significantly compromised adaptive immune system may die shortly unless extreme steps are taken to isolate it from a wide range of infectious agents such as bacteria, viruses, fungi, and parasites.
  • The purpose of adaptive immunity is to eliminate invading infections as well as any harmful chemicals they create. Because these reactions are damaging, it is critical that they only occur in response to molecules that are alien to the host and not to molecules that are native to the host. The adaptive immune system's capacity to identify what is foreign from what is self is a fundamental feature.

Explain why using wind, solar, and biomass energy can lead to sustainable energy use.<br>​
11Alexandr11 [23.1K]

Answer:

These are things that won't be going away. Natural gasses and fossil fuels will likely run out someday or become much harder to find. When you use these sources of energy, they won't be going away and therefore will be sustainable because we can always continue using them.

Does that make sense?

The emergence of resistance is a result of EVOLUTION by natural selection. It is a major evolutionary force.

<h3>Evolution and natural selection </h3>

The term evolution refers to the biological process of descendence with modification.

Natural selection refers to the differential survival or reproduction of the organisms better adapted to a given environment.

In this case, the presence of the pesticide generates an evolutionary constraint, thereby selecting pesticide-resistant individuals in the population.

Santos and Lüderitz are the same distance from the equator, and both cities
Hoochie [10]

Answer:

The difference in altitude between these two regions.

Explanation:

As you can see in the question above, Lüderitz and Santos are two regions that are the same distance from the equator, which indicates that the two regions have the same latitude and are in tropical zones. In addition, the two regions are close to the ocean, but the air in Lüderitz is cooler.

This indicates that there is a difference in altitude in these regions and Lüderitz has a higher altitude than Santos, which is why Lüderitz's air is colder and Santos's is hotter.

Altitude is a geographic term that represents the distance of a region in relation to the level of the sea. The higher the altitude, the greater the distance.

The higher the altitude of a region, the colder its air will be. This is because in high altitude regions, air is thin and has a small capacity to retain heat.
