Biology

sdas [7]2 years ago

Chemical and physical agents are used to control microorganisms.

  • In order to avoid decomposition and spoiling, stop the spread of disease and infection, and prevent undesirable microbial contamination, microorganism control is crucial.
  • Chemical and physical agents are used to control microorganisms. High or low temperatures, desiccation, osmotic pressure, radiation, and filtration are examples of physical agents.
  • Disinfectants, antiseptics, antibiotics, and chemotherapeutic antimicrobial compounds are examples of chemical agents used for control.
  • All live things and viruses are eliminated during sterilization. A sterile object is one that is devoid of all life forms, including viruses and bacterial endospores.
  • Disinfection is the process of getting bacteria off of inert surfaces or items.
  • Decontamination is the process of preparing a physical object or inanimate surface to be handled safely.

Therefore, contaminations via microorganisms can be controlled in various ways.

Let p = purple flowers and p = white, and t = tall plants and t = dwarf. if the uppercase letters represent the dominant alleles
sesenic [268]

If the uppercase letters represent the dominant alleles, purple flowers and tall are the phenotype of a plant with the genotype Pptt.

A gene can exist in different forms across organisms. These different forms are known as alleles.

The subsequent combination of alleles that an individual possesses for a specific gene is their genotype.  

Examples of  genotype include:

  • Hair colour
  • Height
  • Shoe size
  • Eye colour

The sum of an organism’s observable characteristics is their phenotype. A key difference between phenotype and genotype is that, whilst genotype is inherited from an organism’s parents, the phenotype is not.

Whilst a phenotype is influenced the genotype, genotype does not equal phenotype. The phenotype is influenced by the genotype and factors including:

  • Epigenetic modifications
  • Environmental and lifestyle factors

Observing the phenotype is simple – we take a look at an organism’s outward features and characteristics, and form conclusions about them. Observing the genotype, however, is a little more complex.

Genotyping is the process by which differences in the genotype of an individual are analyzed using biological assays. The data obtained can then be compared against either a second individual’s sequence, or a database of sequences.
