Today, any environment surrounded by other ecosystems that are unlike it is subject to Wilson’s theory of island biogeography. Because they are geographically isolated from other related ecosystems, these ecologies are referred to as "islands." Waterbodies divide tropical islands, but this idea also takes into account mountaintops, caverns, and other isolated ecosystems.
<h3>
What is Wilson’s theory of island biogeography?</h3>
- The biologist Edward O. Wilson and environmentalist Robert MacArthur published The Theory of Island Biogeography in 1967. It is widely considered as a foundational work in the ecology and biogeography of islands. The book was reissued by the Princeton University Press in 2001 as a volume in their "Princeton Landmarks in Biology" series.
- The hypothesis that insular biota maintain a dynamic equilibrium between extinction and immigration rates was made more well-known by the book. An island's pace of new species immigration will decline as the number of species increases, while the rate of extinction of native species will rise.
- Thus, MacArthur and Wilson anticipate that there will come a point of equilibrium where the rate of immigration and the rate of extinction are equal.

2. The sperm is carried through a reproductive system.
A gamete is the organisms sex cell. In humans, female gametes are the eggs cells, and male gametes are the spermatozoon. Because of the law of segregation, each gamete carries one allele for a trait, insted of a pair.
However, during sexual reproduction the female gamete and the male gamete come together to form an embryo with the complet pair of alleles for each trait.
In summary, we have two alleles for a trait because one came from our mother and the other came from our father.
A student set up an experiment to show the effect of light color on photosynthesis in Elodea plants. She filled two test tubes with distilled water and placed a piece of Elodea in each of the tubes. She added a drop of phenol red, which turns red in a basic solution and yellow in an acidic solution. She blew in each tube before placing the volumeters on the top of the tube to add carbon di oxide.
She blew in the test tubes to add the carbon di oxide to the tube which caused the distilled water to become more acidic so the phenol red turned yellow, and when she exposes the tubes to different set of color lights. So, in the presence of light it turn the water into red color, which shows the process of photosynthesis depending on the wavelength of different color.

Why did she blow into the tube? Multiple Choice
1) to add oxygen to the tube
2) to add carbon dioxide to the tube
3) to add carbohydrates to the tube
4) to add sodium bicarbonate to the tube
If all humans had the same DNA, and one person got the cold, everyone would die at some point. The more diversity there is the more chance of surviving an outbreak or natural disaster or something. Think of the flu. there are HUNDREDS of strains out there. some are resistant to our medicines and others aren't.
