The kind of genetic variation in happy-face spiders that Dr, Gillespie was studying is called Polymorphism <span>which includes ecology, morphology and the behavior of the happy-face spiders. Polymorphism is a discontinuous genetic variation that results in the occurrence of several different forms or types of individuals among the members of a single species. The happy-face spider exhibits an array of color patterns on the back of its abdomen, sometimes resembles a smiling face. Despite the variation in colors, all of the happy-face spider; have the same anatomical features, interact in the same ways with their environments and with other organisms, they share the same reproductive behaviors and methods of catching insect prey and also freely mate with one another. The study of protein by scientists in the happy-face spiders revealed that different islands had very different levels of variation which means the dispersal between the island is not very common. </span>
Answer:
Tides
Explanation:
The intensity of the water from the rise and fall of tides is a sort of kinetic energy, and tidal energy is generated by the movement of our tides and seas. Gravitational hydropower, which uses the flow of water to drive a turbine to create energy, is surrounded by tidal power.
The answer is: D. all of the above.
When Earth receives energy from the Sun, some energy is reflected back into space, some is absorbed by the atmosphere, and some is absorbed by land and water on Earth's surface.
Answer:
Land restoration can include the process of cleaning up and rehabilitating a site that has sustained environmental degradation, such as those by natural cause (desertification) and those caused by human activity (strip mining), to restore that area back to its natural state as a wildlife home and balanced habitat.
Explanation:
- setting up reliable water provisioning (e.g. by digging wells or placing long-distance water pipes)
- stabilizing and fixating the soil
