Answer:
C
Explanation:
genetic recombination is the exchange of genetic material between different organisms
Answer:
Invasive species can change the food web in an ecosystem by destroying or replacing native food sources. The invasive species may provide little to no food value for wildlife. Invasive species can also alter the abundance or diversity of species that are important habitat for native wildlife.
The actual patterns of DNA variation in humans reveal that those from African populations also contain almost all of the common DNA found in other races such as Asians, Europeans, and other novel variants.
African populations were shown to contain alleles (genetic variations) not present in non-African populations but nearly all of the alleles common in non-African populations are present in African populations. Thus, although externally, different races may present various physical characteristics, our genes dictate that we are more similar than we actually think/believe.
