Answer:
The intrincate plumage of male birds of paradise has become increasingly elaborate throughout their evolution due to females mating preferentially with males that display the most impressive feathers. This is an example of NATURAL selection.
Explanation:
Darwin's Natural Selection theory states that some organisms tend to have more favorable traits between other organisms who belong to the same species. Upon this process and throughout adaptation, organisms pass on those treats to next generations. This gives place to reproduction and perpetuation of the species, avoiding extinction.
Cyanobacteria had a role in the evolution of eukaryotic cell, more precisely their organelles. It has been shown that chloroplast, cell organelles found in some eukaryotic lineages, which are specialized in performing the photosynthesis evolved from cyanobacteria through the process called endosymbiosis. In this process, photosynthesizing cyanobacteria was engulfed in some ancient eukaryotic cell. Eukaryotic cells have evolved from the endosymbiotic events.
<span>By producing and releasing O2 (as a byproduct of photosynthesis), cyanobacteria are thought to have converted the early oxygen-poor, reducing atmosphere into an oxidizing one. This caused the Great Oxygenation Event which dramatically changed the Earth's life forms and led to the formation of multicellular organisms.</span>
It depends on their genes if they had an ancestor with Brown eyes
Answer:
A. Methane
Explanation:
Methane is a gas not a solid. Every other answer choice is a solid.
Answer:
The correct answer is vasogenic edema.
Explanation:
A kind of cerebral edema in which the blood-brain barrier is disrupted is termed as vasogenic cerebral edema. It refers to extracellular edema that primarily influences the white matter through leakage of fluid from the capillaries.
It is primarily witnessed surrounding the brain tumors, that is, both primary and secondary and the cerebral abscesses, however, some of the vasogenic edema may be witnessed around the developing cerebral hemorrhage and cerebral contusion.
