<u>Answer:</u>
An example situation of artificial selection is "More African elephants today naturally lack tusks compared to the elephant populations 100 years ago, because big game hunters sought elephants for ivory".
<u>Explanation:</u>
- The process of breeding animals to acquire the desired characteristics by the external means other than natural selection and behavior of animal itself is called as artificial selection.
- The first artificial selection was carried out by Darwin when he mated penguins that would have a higher chance of breeding.
- The practice of artificial selection was existing in human civilization a long time ago.
- This process was used to use wild animals and domestic animals in battles and other household works.

<span>Meiosis I
Meiosis is the process of cell division by which involving gametes. Cell division is just the same for sperm and egg cells, but they have distinguishable descriptions and labels in the process. Spermatogenesis is for the males’ sperm cells and oogenesis is the process for females’ egg cells. The cell division of meiosis involves the two phases, respectively meiosis I and meiosis II. </span>Meiosis I like mitosis is the cell division that produces diploid cells<span>. These diploid cells are cells that contain a complete pair of chromosomes which is 46. The result is two diploid cells after the first meiosis. To provide clear explanation, in contrast haploid cells only contain 23 chromosomes and are created after meiosis II which is 4 in number.<span>

Answer:
Explanation:Biodiversity prospecting is the exploration, extraction and screening of biological diversity and indigenous knowledge for commercially valuable genetic and biochemical resources. While it is true that biodiversity prospecting does not always involve the use of indigenous knowledge, it is clear that valuable chemical compounds derived from plants, animals and micro-organisms are more easily identified and are of greatest commercial value when collected with indigenous knowledge and/or found in territories traditionally inhabited by indigenous peoples.
Biopiracy can be defined as the stealing of knowledge from traditional and indigenous communities or individuals. The term can also be used to suggest a breach of a contractual agreement on the access and use of traditional knowledge to the detriment of the provider and bioprospecting without the consent of the local communities. The Action Group on Erosion, Technology and Concentration [ETC group, Canada (former RAFI)] defines it as “the appropriation of the knowledge and genetic resources of farming and indigenous communities by individuals or institutions seeking exclusive monopoly control (usually patents or plant breeders’ rights) over these resources and knowledge”.
