<u>Infrared</u> waves have a long wavelength and do not possess sufficient energy to kill bacterial cells, while <u>UV</u> waves have a short wavelength and can be used to sterilize a surface.

  • When ultraviolet light, also known as ultraviolet germicidal irradiation, is released at its most effective wavelength of 253.7 nanometers (nm), it has the greatest ability to kill germs and render microbes inert (UVGI). When transmitted at wavelengths different than those recommended, germicidal efficacy declines.
  • To efficiently deliver the appropriate amount of UV radiation for the desired application, high-quality UV sterilization lamps are crucial.
  • By altering cell DNA, UV radiation sterilization efficiently renders bacteria inert.
  • Because DNA is necessary for cell reproduction, damage to the DNA's structural integrity prevents cells from multiplying and causing disease.
  • The cell absorbs the UV rays, resulting in the formation of pyrimidine dimers.
  • Instead of bonding across the double helix, this causes two nearby thymine or cytosine bases to interact with one another.

List detailed reasons why deforestation is important?
Lilit [14]

Explanation:

Deforestation is the removal of trees from forested regions. Forests are integral to nutrient cycling, they provide an important habitat for numerous species, and regulate several abiotic and biotic factors.

The biology of an environment involves all non-living, abiotic factors such as climate, water, vegetation, sunshine, and temperature; and biotic factors which are living ecosystem components such as plants, fungi, microbes, and animals. Such influences work within a group, and over time lead to a gradual change in an environment.

Apart from leading to a loss in critical species, this may also have several far-reaching implications such as:

  • soil erosion-  soil exposed by the removal of ground cover is often easy to displace
  • flooding- forests are important in taking in and releasing water regularly; without forests, some regions may experience flooding long-term.
  • oxygen-  vegetation is crucial in oxygen cycling as a byproduct of photosynthesis

In the future, increased deforestation may have several far-reaching effects. This is most likely to affect small island nations, regions below sea-level and tropical ecosystems most...

  • Decreased rainfall and CO2 cycling- trees are important in water and CO2 cycling. This can lead to droughts (an extreme lack of water) in some regions and transform wetlands and other habitats into uninhabitable regions.
  • Climate change- increased CO2 levels contribute to a global heating effect and contribute to the phenomenon of climate change. This may cause sea levels to rise, and contribute to land mass losses.

Protists can be:________.
PilotLPTM [1.2K]

Answer:

e) unicellular, colonial, or multicellular.

Explanation:

Protists originates from the Kingdom Protoctista. They comprise of organisms that are unicellular (Amoeba) or unicellular-colonial (volvox) in nature and which have no tisssues, therefore they are at the cellular level of organization.

Examples include, Amoeba, Paramecium, Euglena, Slime mold, Kelp, Diatoms, DInoflagellates. etc.

Some of them are also considered to be multicellular eukaryotes e.g slime molds, red algae etc. Eukaryotic organisms are organisms that possess cells containing a nucleus.

Characteristics in which protists exhibit varies from one species to the other.

For example, the mode of nutrition in eukaryotic algae are autotrophic in nature, in amoeba, they are gifted with pseudopods(false feets) in which they used to engulf prey(a term  known as phagocytosis) therefore making them to be heterotrophic in nature.

In protist, locomotion varies from one organism to another. For example, in Amoeba , locomotion is achieved by extending and retracting pseudopods, Euglena are flagellated in nature , hence they move with the flagella. In Paramecium that are ciliated in nature, they move by propelling their cilia. etc.

What are some negative impacts of carbon storage in ocean water and
Dmitriy789 [7]
Carbon is harmful to the earth, as known. And when it reaches water it’ll effect humans in many ways, it’ll usually make the water more acidic! And for us humans it’s harder to filter the water.
