Answer:
Gene flow is the exchange of alleles between two or more populations. For this reason it is sometimes referred to as allele flow or gene migration. While migrating animals often carry new alleles from one population to another, they must interbreed with the new population for gene flow to occur. In the image below, a beetle from a population of brown beetles migrates into a population of green beetles.
The answer is c hope this helps
Answer:
Tricuspid valve: Allows blood to pass from the right atrium to the right ventricle; prevents blood from flowing back into the right atrium as the heart pumps (systole).
Explanation:
1. Enterococcus and coliforms can enter the water through feces. Although a water sample is negative for these bacteria, it could still be infected by pathogens from other sources than feces.
2. Culture media are sterilized by filtration because they could contain antibiotics or serum which deteriorate upon heat. Filtration is used in sanitation to remove large particles.
3. In the membrane filter technique, it is assumed that <span>all viable bacteria will form colonies. This means that formed colonies develop from the viable bacteria so that the number of colonies suggests the number of bacteria.
4. E. coli is negative for Citrate and Voges-Proskauer tests, and is positive for Indole and Methyl red tests.
5. The answer is yes because eo</span><span>sin-methylene blue agar is inhibitory to Gram+ bacteria.</span>
Answer:
Beak shape/size or song or behavior or mechanical/chemical differences or time of mating or location on the island or primary food source differs between the Big Bird lineage and G. fortis.
Also acceptable: Description of another mechanism that prevents males and females from different populations from encountering each other/recognizing each other as potential mates.
