A population of organisms must exist. There must be variation among the members of the population. There must be a mechanism by which some members of the population can produce more offspring than other members. There must be a mechanism by which the variation among members of the population is passed on to their offspring.
Acclimation is the physiological response or phenomenon which is responsible for survival of salmon in fresh water and salt water.
When a young salmon starts its sea journey it travels wide distances in search for oceans completing a leg of their journey. They travel back to home streams for spawning. This survival in different osmotic potentials and salinity is due to osmoregulation and acclimation. System of salmon detects saline change and instigates a negative feedback system to the body water concentration. Similar feedback works contrastingly when salmon is in fresh water or marine streams of water.
Hence, the physiological response occuring in salmon is acclimation.

The answer is C. Metalloids
Hair is a good example of physical contamination in food.
<h3>cross contamination: what is it?</h3>
- Contaminants can enter food in a variety of ways, including during production, processing, or cooking.
- Food isn't always immediately exposed to contaminants.
- Cross-contamination is the unintentional introduction of pathogens from a surface, item, or person into the food.
- The four most typical causes of cross-contamination are bugs, food handlers, utensils, and clothing.
- When people refer to cross-contamination, they typically mean biological or allergenic pollutants, however any of the four contaminants may be involved.
<h3>Physical contamination: what is it?</h3>
- Foreign things that contaminate food are referred to as physical contamination.
- Between farm and table, it can occur at any time.
- Physical contaminants can lead to injuries including choking, cutting, or tooth damage, but they can also introduce dangerous bacteria that have their own risks.
- Finding something in one's meal can be highly upsetting, even if one is not sick or hurt.
