Answer:
Allopatric speciation
Explanation:
This is the development of different species without the influence of geographical separation. This can occur when a population is physically isolated from the rest of its species, such as by a river or mountain range, and begins to evolve independently. Over time, the isolated population may develop differences in traits and adaptations that make it unable to mate with the original population, leading to the formation of a new species.

What are the methods of prevention biological hazards in a hospital?
Biological hazards in hospitals can be a serious issue, ranging from the spread of infectious diseases to occupational exposure to hazardous materials. Fortunately, there are a number of methods of prevention that can reduce the risk of these threats.
One of the most effective methods of prevention is through rigorous hygiene protocols. All staff members must be trained in proper hand hygiene techniques, including the use of soap, water, and alcohol-based sanitizers. It is equally important that all surfaces, equipment, and tools are cleaned and disinfected regularly. Additionally, any waste materials should be disposed of properly to avoid cross-contamination.
Another key element of prevention is the use of personal protective equipment (PPE). All staff members must wear the appropriate PPE for their job, including masks, gloves, gowns, and eye protection. All staff must be aware of the correct way to put on and take off the PPE, and any contaminated PPE must be disposed of immediately.
Finally, it is essential that all hospital staff be aware of the risks of biological hazards and how to prevent them. This includes regular training on infection control practices and proper handling of hazardous materials. Regular monitoring and assessment of the hospital’s hygiene and safety protocols should also be conducted to ensure that all staff members are following the correct procedures.
By following these preventive measures, hospitals can significantly reduce the risk of biological hazards and maintain a safe and healthy environment for both patients and staff.

How would you describe 2 chromosomes that have the same genes in the same order?
A homologous pair of chromosomes has the same genes in the same order, but there may be variation between them, resulting in distinct alleles.
In genetics, homozygous means having inherited the same versions (alleles) of a genomic marker from both biological parents. As a result, a person who is homozygous for a genetic marker has two identical copies of that marker.
Before dividing into two cells, a cell copies all of its chromosomes. These duplicates, known as sister chromatids, are identical.
Homologous chromosomes are those that share the following characteristics: The similar structural characteristics (e.g. same size, same banding patterns, same centromere positions) The same genes are found at the same loci (while the genes are the same, alleles may be different)

Why genetically modified food is important?
Most existing genetically modified crops have been developed to increase yield by introducing resistance to plant diseases or increased herbicide tolerance.
Genetically modified foods, as well known as genetically engineered foods as well as bioengineered foods, seem to be foods derived from organisms whose DNA has been altered using genetic engineering techniques. Genetic engineering techniques, when compared to previous methods such as selective breeding as well as mutation breeding, allow for the introduction of new abilities as well as greater control over traits. The twentieth-century discoveries of DNA and advances in genetic technology were crucial in the creation of transgenic technology.
Genes encrypting desired characteristics, including such higher nutrient levels, pesticide but also herbicide resistance, as well as the presence of therapeutic substances, have been frequently extracted but rather transferred to the target organisms, allowing them to survive and produce more.
