Biotechnology can be defined as using living organisms and to develop new products that can help human beings. Biotechnology has had an impact as follows:

Medicine: In the field of medicine, Biotech has resulted in the discovery and mass production of 'small molecule pharmaceutical drug'. Other examples include Genetic testing and genetic diagnoses of diseases.

Agriculture: Biotech has led to the development of GMC (genetically modified crops) which was able to bring about Green revolution and increase world production of food approx. 10 times.
In animals, selective breeding and mutation breeding are examples of how Biotech has helped in factory farming methods.

Conservation: Biotechnology is being used to harness the potential of creating energy from plant-based sources such as Plankton and Algae. Biotech has also led to the development of trees and plants which are more resilient to climate change and can help in transforming communities.

When malaria outbreak occurs, the allele frequencies change and only the organisms that possess the alleles which help them to survive this outbreak due to resistance against malarial infection will be selected by nature and hence, this is an example of natural selection.

2. The correct order of the phases of mitosis are as follows: PROPHASE, METAPHASE, ANAPHASE AND TELOPHASE.
Mitosis is the process of cell division by which a cell is divided into two new cells. The process occurs in four basic stages and result in the formation of two new cells.
3. The following terms are related to sexual reproduction: MATING SYSTEM, GAMETE FORMATION AND AMPLEXUS.
Amplexus refers to the mating positions of frogs and toads during sexual reproduction. Mating system refers to the number of mating partners that an animal has during the mating period. Gamete formation is the process by which sex cells are made and it occurs in both male and female animals.
4. As a cell is preparing to divide by mitosis, the DNA MUST BE COPIED.
When a cell is getting ready to divide by mitosis, it will undergo a stage called interphase, during which the cell prepare for cell division. During interphase, the cell undergo some process and these include the copying of the DNA. The cell copies its DNA so that it has two copies of each strand.
