Answer:
D
Explanation:
Crude oils, shale, and natural gas are some of the fossil fuels formed in this way. They are specially formed when vast amounts of algae die and sink to the bottom of the oceans over time and accumulate with sediments. They become buried under vast layers of sediments that apply high pressure. Over time, the high pressure and temperature turn the organic molecules into fossil fuels.
Answer:
D. Evolutionary relationships
Explanation:
phylogeny describes the relationships of organisms which evolved on most closely related species
Answer and Explanation:
Corals are translucid or white, but they look brightly colored because they host symbionts with colorful photosynthetic pigments
. They can host different organisms that live on and among them, giving place to an amazing ecosystem.
One of these organisms is the photosynthetic unicellular microalgae, called zooxanteles, that are colorful and provide nutrients to the coral.
Corals provide shelter and protection to the algae, while algae provide nitrogenated nutrients, sugars, and color to the corals. Algae can store nitrogen in their tissues as nitrogen-rich crystals, which are constantly provided to corals.
This symbiotic relation allows corals to grow in different environments that are poor in nitrogen or other nutrients, such as the tropical clear waters.
When changes in radiation, temperature, or salinity in water occur, corals react to these changes losing these algae and becoming translucid again.
If I were hired as a genetic counselor to advise a couple about the odds of the couple having a baby with a genetic disorder and I wanted to order lab tests to be done on the pregnant mother to determine if the baby has a genetic disorder (amniocentesis)-what kind of test would be done? How would the test determine if the baby has a genetic disorder or not? If it is determined that the couple's baby has a genetic disorder, then what advice should I provide to that couple? Why? What if the couple went against my advice? Whose advice (mine-the genetic counselor representing science or the couple representing society) should be considered?
We see that this is a region near the continents, so it is probable that there is the boundary of a tectonic plates around there. Since there are islands there, it is quite probable that there is a subduction zone near them which means that the oceanic crust is going below the continental one and the continental is slowly elevated. This also shows that the boundary is convergent, since transform boundaries do not lead to elevation. Near convergent boundaries, there are frequently volcanoes and shallow earthquakes. Finally, the climate near Alaska is cold and this does not depend on whether islands are near a boundary or not. So, 2 4 and 5 are correct.
