Which is allopatric and which is sympatric
Helen [10]

Answer: The correct answer is-

Allopatric-  option 2.

Sympatric - option 1.

Allopatric and sympatric are primarily the two major mechanisms for  speciation ( formation of new species from an ancestral species).

In allopatric speciation, a population splits into two different species when it is isolated by physical or geographical barrier.

On the other hand, sympatric speciation occurs wihtin the same area. A population splits into two species that is becomes reproductively isolated when a change in the chromosome number occurs.

Thus, option first corresponds to sympatric whereas option second shows allopatric speciaton.

Claims • Evidence • Reasoning Make a claim about how the energy of a microwave compares to the energy of a gamma ray. Summarize
pishuonlain [190]

Answer:

Today, the consensus among scientists, astronomers and cosmologists is that the Universe as we know it was created in a massive explosion that not only created the majority of matter, but the physical laws that govern our ever-expanding cosmos. This is known as The Big Bang Theory. For almost a century, the term has been bandied about by scholars and non-scholars alike. This should come as no surprise, seeing as how it is the most accepted theory of our origins. But what exactly does it mean? How was our Universe conceived in a massive explosion, what proof is there of this, and what does the theory say about the long-term projections for our Universe? The basics of the Big Bang theory are fairly simple. In short, the Big Bang hypothesis states that all of the current and past matter in the Universe came into existence at the same time, roughly 13.8 billion years ago. At this time, all matter was compacted into a very small ball with infinite density and intense heat called a Singularity. Suddenly, the Singularity began expanding, and the universe as we know it began.
