Response:
The introduced species, lacking natural predators in the new environment, can reproduce excessively and deplete resources needed by native species, potentially leading them to extinction.
Clarification:
Selective pressure refers to factors that influence an organism's behavioral changes. These pressures can arise from living (biotic) or non-living (abiotic) elements.
Such pressures may cause the organism to modify their behaviors, shift habitats, experience population decline, or even undergo mutations. These adaptations may affect other species in the same area positively or negatively.
Possible consequences of selective pressure include:
- Flock X might begin consuming different food sources.
- Flock X may relocate to find fruit.
- Flock X could gradually reduce in population.
- Flock X might attempt mutation.
B. The organism does not engage in photosynthesis. Plants are autotrophic and synthesize their own food through photosynthesis, converting light energy to chemical energy. In contrast, fungi are heterotrophic and do not have this ability.
To ascertain allele frequency, one must take into account the dominant and recessive alleles in a genotype.
According to the provided data, the following calculations yield the allele frequencies:
allele A = 100/300, allele B = 50/300, allele O = 150/300
Therefore, the frequency for allele A equals 0.33 or 33%, allele B equals 0.17 or 17%, and allele O equals 0.50 or 50%.
