Option A, The pressures of a hatchery environment and of the wild environment select for different traits.
The various pressures in wild environment include the competition for food and survival, threat of prey etc. The effect of domestication on salmon can also be a reason for its low productivity in wild environment. Some other factors that might have affected the regular productivity of salmon in wild environment include- captive rearing, inbreeding among close relatives and ability of some fish to adapt to the unique hatchery environment.

Innate behavior is very often considered to be th eresult and a consequence of learning which was done in the earliest stages of life; womb, infancy up to childhood possibly. Most of the time, this learning has to either be model learning of reinforcement learning where the organism or child, if we're talking about human beings, get feedback once they do something; either negative - diminishes the behavior, or positive - increases it.
The smooth endoplasmic reticulum manufactures lipids and carbohydrates.
The Rough endoplasmic reticulum assists in the synthesis of proteins and send them to the Golgi bodies.
What is the endoplasmic reticulum?
The endoplasmic reticulum (ER) is a continuous membrane structure that divides into flattened sacs in the cytoplasm of eukaryotic cells. It has a variety of roles but is notably crucial for protein synthesis, folding, modification, and transport.
- Rough endoplasmic reticulum: Its name comes from the rough texture of its outer (cytoplasmic) surface, which is caused by the presence of ribosomes there. Rough ER is located next to the cell nucleus, and the nuclear envelope's outer membrane is continuous with its membrane.
- Smooth endoplasmic reticulum: It is distinct from ribosomes and has a different set of functions. The synthesis of lipids, including as cholesterol and phospholipids, which are needed to create new cellular membranes, is carried out by the smooth ER. Smooth ER is crucial for the synthesis of steroid hormones from cholesterol in certain cell types.

Answer:
C) They are part of a community
Explanation:
A community represents the sum total of populations of different species present together in an area or ecosystem. In a community, the organisms of these different species may benefit or harm each other and exhibit little or more interdependence. In the given example, beer, insects, ants, chipmunks represent the organisms of different species that are present together in a habitat. They interact with each other in various ways. For instance, the bear is a predator of insects.
