Answer:
D) sympatric speciation and habitat isolation
Explanation:
Sympatric isolation is a form of evolutionary process whereby different species from an ancestral origin evolve within the same geographical environment as a result of reproductive isolation.
Habitat isolation is a form of reproductive isolation which occurs when two populations of a species inhabiting overlapping habitats become unable to interbreed with each other.
Reproductive isolation (habitat isolation) that occurs in the fleas is as a result of the new species becoming separate from it's ancestral species which feed only on pronghorn antelopes, although both species can still be found in the same geographical location (rangeland). The new species now have preference for cattle blood, and so are now found on cattle.
In the situation of the two new species of flea that would evolve, it can be said to an example of sympatric speciation and habitat isolation, since the host mammal is assumed to be their habitat and both the cattle and pronghorns often associate with one another in the same open rangeland.
Cellular respiration included the metabolic pathways of glycolysis, the Krebs cycle, and the electron transport chain is described below.
Explanation:
1. Catabolism of glucose in glycolysis and pyruvate oxidation-Produces NADH for use in ETC.Produces acetyl-CoA for entry into kerbs cycle.Provides energy for phosphorylation of ADP.
2. Oxidation of intermediates in the Krebs cycle-Produces NADH or FADH2 for use in ETC.Releases high energy electrons for use in ETC.Provides energy to pump protons against their concentration gradient.Produces GTP for phosphorylation of ADP.
3. Formation of a proton gradient by the electron transport chain-The flow of protons through membrane-bound ATP synthase generates ATP.Provides energy for phosphorylation of ADP.
Sand dunes are formed from wind movement. There needs to be a large amount of loose sand in an area with hardly any vegetation, enough wind to move grains of sand and some kind of obstacle to make the blowing sand lose its momentum and settle in a new place.
