The fungi are breaking down the wood of the dead trees to use their chemical products in building its own structure. This process involves chemical reactions by the fungi, which are all forms of chemical decomposition : the formation of smaller molecules from larger molecules.
What else can I help you with?
What are the three aspects of bio-remediation?
The three aspects of bio-remediation are: 1) using biological organisms to clean up contaminated environments, 2) promoting the growth of specific microbes that can degrade pollutants, and 3) creating conditions that support the biological processes of degradation.
What are the disadvantages of protease in biological detergents?
Proteases in biological detergents can cause skin irritation or allergies in some individuals due to their enzymatic activity. They may also degrade certain fabrics over time if not used properly or in high concentrations. Additionally, proteases can have a negative impact on aquatic ecosystems if they are not adequately removed during wastewater treatment processes.
Why do forensic pathologists put bodies into a freezer at the morgue?
Putting bodies into a freezer at the morgue helps slow down the process of decomposition, which can preserve evidence and make it easier to conduct detailed examinations and investigations later on. The cold temperature also helps prevent the growth of bacteria and insects that could further degrade the body.
How long does it take for DNA to degrade in different environmental conditions?
The time it takes for DNA to degrade varies depending on environmental conditions. In general, DNA can degrade within a few weeks to several years in soil, water, or air. Factors such as temperature, humidity, and presence of enzymes can affect the rate of degradation.
Can you still get DNA from bleached hair?
It is unlikely to obtain usable DNA from bleached hair due to the chemical processes involved. Bleaching can damage and degrade the DNA present in the hair, making it challenging to extract for analysis.
Is decomposition reaction a chemical reaction?
It depends on the nature of the decomposition. if you are talking about biodegradeability in a substance, then no, its decomposition is mainly due to bacteria that will break down the various particles in the substance ("eat" them). There are, however certain chemical reactions which take place within the bacteria as the substance is being broken down, (much like those that happen in the human body) and the possibility of there being other products in the vicinity which may react to the substance (and degrade it) is always present. It could be said that decomposition is therefore a chemical reaction (or rather a series thereof), but with biodegradeability in mind it is not generally thought of as such.
What is the introduction of chemical physical or biological agents into water that degrade the water called?
Pathogens.
What chemical has caused the ozone to degrade?
CFC's have caused ozone to degrade. They react with ozone and deplete it.
Polyurethane reaction with chlorine?
When polyurethane is exposed to chlorine, it can undergo a chemical reaction that can result in degradation of the material. This reaction can lead to discoloration, embrittlement, and reduced mechanical properties of the polyurethane. It is important to avoid exposing polyurethane to chlorine-containing substances to maintain its integrity and performance.
What is non biodigradable?
It is a substance that does not disintegrate or degrade into natural substances through the biological process decay.
How do you know a rotten apple has gone through a chemical reaction answer?
A rotten apple undergoes a chemical reaction characterized by changes in color, texture, and smell. The breakdown of organic compounds due to enzymatic activity and microbial action leads to the production of new substances, such as acids and gases, which contribute to its foul odor. Additionally, the apple's flesh becomes mushy as cell walls degrade, indicating a chemical transformation. These observable changes confirm that a chemical reaction has occurred during the rotting process.
Why must a forensic scientist collect biological evidence before physical evidence?
Biological evidence is much more likely to degrade and become unusable before physical evidence does.
What is chemical sludge and difference between chemical and biological siudge?
Chemically sludge is obtained when precipitating soluble or insoluble chemicals present in the water or any kind of effluent coming out of chemical industries. Generally iron was used as an precipitate pollutants present in waste water. the final product after precipitation is called chemical sludge which is filled in a land into heap or used in road construction. Biological sludge is formed when microorganisms are used to degrade toxic chemicals present in waste water. The excess biomass formed is termed as biological sludge which contains adsorbed toxic chemicals in their cells, toxic metabolites formed during degradation of wastes, dead biomass etc.
What is the definition of chemical corrosion?
Chemical corrosion is the process of deterioration or destruction of a material due to a chemical reaction with its environment, leading to the loss of the material's properties or functionality. This often occurs when a material comes into contact with substances such as acids, bases, or salts, causing it to degrade over time.
What do batteries store?
A battery stores energy through the potential difference between the anode and cathode of the battery. When there is no circuit the potential power is stored somewhat indefinitely (although it can degrade over time). Once a circuit is made, an electrolytic cell is created releasing energy as the chemical reaction occurs.
How chemical energy formed and use?
Chemical energy is formed when bonds between atoms are broken or formed during chemical reactions. This energy is stored in the chemical bonds of molecules and is released when these bonds are broken, providing the energy needed for various biological processes like metabolism, muscle contractions, and nerve impulses. Living organisms use chemical energy from the food they consume to power their cells and sustain life.
will glass decompose?
No. Glass bottles will undergo physical changes in the environment such as breaking or sharp edges smoothing out (think seaglass), but the natural processes of chemical decomposition doesn't work on glass. The same goes for styrofoam.
