Answer:
It's a little difficult to see the difference between the finch 1 and finch 2 population lines, but their trends should match those of the food. This answer is assuming the finch 1 population aligns with the seeds line and the finch two population lines up with the fruit line: <u>The finch 1 population has a beak adapted to eating seeds and the finch 2 population has a beak better adapted to eating fruit</u>
Explanation:
Since we are given data for both the food source and the finch population, the answer will most likely reflect that. Therefore eliminating choices A (disease) and C (feathers). Again, this answer is assuming the finch 1 population aligns with the seeds line and the finch two population lines up with the fruit line. The lines for the finch population will match with the availability of food, so less seeds mean less finch 1 and when the amount of seeds rise up you can see the population of finch 1 also rises.
Answer:
Diffusion
Explanation:
Substances like CO2 and water move into and out of a cell by diffusion from an area of high concentration to an area of low concentration.
Answer:
b. Detachment of a separate hybridized probe molecule from the template DNA
Explanation:
Molecular beacons are a type of genetic probe that enables the hybridization of oligonucleotides. These molecules have a flourishing component that binds to a nucleotide sequence and allows the identification of this nucleotide sequence in DNA or RNA without the release of radioactivity. For the use of these molecular beacons to be possible, one needs complementarity between the model DNA and the probe sequence, illumination of the hybridized beacon to detect fluorescence and proximity-based quenching of the fluorophore prior to beacon hybridization.
