<span>The characteristics that scientists used to classify living organisms into six kingdoms include the following:
1. Cell type: living organisms are classified into prokaryotes and eukaryotes based on the presence of nucleus and distinct arrangement of the organelles in their cells.
2. Mobility: living organisms are categorized into kingdoms based on their ability or inability to move about.
3. Cell structure: the cells structure was used to divide living organisms into plants and animals. Those living organisms that have cell wall are classified as plants while those who do not have cell wall are classified as animals.
4. Number of cells: living organisms that are made up of only one cell are classified as unicellular while those with many cells are termed multi cellular.
5. Reproduction method: living organisms are classified based on whether they reproduce sexually or asexually.
6. Manner of obtaining energy: living organisms that can prouduce their own food are called autotrophs while those that can not produce their own foood are termed heterotrophs. Plants are essentially categorised as autotrophs while animals are described as heterotrophs.</span>
Considering the following choices;
A) Behavioral isolation.
B) Reproductive isolation.
C) Genetic isolation.
D) All of the above.
Answer;
D all of the above;
Mating calls, strutting, displays of plumage and coded sounds result in behavioral isolation, reproductive isolation, and Genetic isolation;
Explanation;
Isolation mechanism are those aspects that prevents species or groups of organisms fro reproducing sexually.
Genetic isolation, involves population having a little genetic mixing with other organisms within the same species.
Reproductive isolation is a situation in which different species may live in the same area, but the properties of individuals prevent them from interbreeding.
Behavioral isolation helps members of the same species to identify each other as proper mates.
