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.
Answer: 1 : knowledge about the natural world that is based on facts learned through experiments and observation. 2 : an area of study that deals with the natural world (as biology or physics)
Explanation:
Answer: It has a narrow geographic range
Explanation:
Species with narrow geographic range easily face the risk of extinction when their localize geography faces drastic change and becomes unconduceive for their survival. On the contrary, a specie that is will dispersed geographically stands a higher chance of survival because even if there is a drastic event in a particular location, the one at another location will still survive.

Answer:
Pyruvate take place after the process of glycolysis.
Explanation:
Pyruvate as intermediate take place in the process of photosynthesis after glycolysis process. One glucose molecule is converted into two molecules of pyruvate. This pyruvate molecule then converted into acetyl CoA, which is a two-carbon molecule. A molecule of coenzyme A is a very important reactant for this reaction, which produces a molecule of carbon dioxide and reduces a NAD+ to NADH.
