Answer:
1. Intraspecific
2. speciation
3. fossil record
4. The fossil record provides empirical evidence for evolution because it shows that species now aren't the same as species that existed in the past and that small changes happen over time to create new species.
5. A geographic variation in the fossil record occurs when two similar organisms occupy the same time span in two different places. These organisms hold the same purpose within the overall ecology.
6. A more detailed fossil record is preferable for supporting evolution because it allows for the instances of gradual change to be recorded and placed into broader speciation events.
7. Fossils provide a great many intermediaries that connect past species with their living descendants.
8. Intraspecific competition is competition that occurs within species. This is the competition that drives natural selection.

Answer:
During crossing over, part of one chromosome is exchanged with another. The result is a hybrid chromosome with a unique pattern of genetic material. Gametes gain the ability to be genetically different from their neighboring gametes after crossing over occurs.
The organelle is labeled is nucleus, which means, where the chromosomes and one or more nucleoli are located immersed in the nucleoplasm or also karyolymph.
<h3>What is a nucleus organelle?</h3>
The nucleus, generally the largest eukaryotic cell organelle is the region delimited by membrane, where the chromosomes and one or more nucleoli immersed in the nucleoplasm or also karyolymph are located.
The nucleus of an organelle is composed of the karyotheca, chromatin, nucleoplasm and nucleolus.
