Answer:
Frequency of dominant allele is 0.9029
Explanation:
Total number of organisms = 12,845
Number of organisms representing dominant trait = 11,596. These organisms might have heterozygotes with one dominant allele and one recessive allele.
Hence, Number of organisms with recessive alleles = 12845 – 11596 = 1249
Frequency of recessive allele (q) = 1249/12845 = 0.0971
Frequency of dominant allele (p) = 1- q = 1- 0.0971 = 0.9029

Answer:
Answer is A. Vicariance does not require organisms to disperse.
Explanation:
Vicariance occurs when there is a sudden occurrence barrier , such as geographical area barrier that cause the isolation of species of organisms.
Dispersal involves the movement of the organism while vicariance is the change in environment due to sudden occurrence in the area.
In this case, vicariance does not involve movement of organisms while dispersal involves movement of organisms.
If there was not a constant Input of energy into the ecosystem then nothing would have the power to do anything and nothing would be alive. the energy starts with the sun, then goes to plants, then animals that eat the plants, and then the animals that eat those animals, Ect. if this chain reaction did not happen then the plants wouldn't have to power to go through photosynthesis and then we would get no energy. the amount of energy lessen with every chain that it goes through, this is why we get more energy eating plants and why they are healthier.
