Unlike natural selection, genetic drift does not depend on an allele’s beneficial or harmful effects. Instead, drift changes allele frequencies purely by chance, as random subsets of individuals (and the gametes of those individuals) are sampled to produce the next generation.
Every population experiences genetic drift, but small populations feel its effects more strongly. Genetic drift does not take into account an allele’s adaptive value to a population, and it may result in loss of a beneficial allele or fixation (rise to 100\%100%100, percent frequency) of a harmful allele in a population.
The founder effect and the bottleneck effect are cases in which a small population is formed from a larger population. These “sampled” populations often do not represent the genetic diversity of the original population, and their small size means they may experience strong drift for generations.
The answer is; The slower the cooling the larger the crystals
Slow cooling allows the aqueous molecules of the compound to find a perfect geometry and grow into a large crystal. Fast cooling causes impurities to be incorporated into the growing lattice hence atagonizing the growing crystals.
Answer:

The clamming industry in Long Island used to be very lucrative, raking in as much as $100 Million annually. By the 1970s, it had shrunk to less that $40 million per annum.
<h3>What was to blame for the decline according to the article mentioned above?</h3>
2. According to the New York Times Article of 1985, the reason for the steep decline in the value of the Clamming industry was related to the loss of confidence in the health safety of eating raw shellfish.
3. According to the remarkable discovery of the "208 Study", it was discovered that there was a connection between land use and underground water quality. It was also discovered there was a negative impact of dumping sewers in the ocean on the production of shellfish
4. Some of the solutions that were proposed to manage this situation are:
- Using sewers to collect effluents into a septic treatment plant. rather than dumping them into the ocean.
- The implementation of secondary sewage treatment supplemented by ocean disposal of the effluents and
- Monitoring the salinity levels of the clamp ecosystem.
