Answer: The question is incomplete because the options are not given. Here are the options gotten from another website.
A. adaptation
B. reproduction and development
C. response to the environment D. energy transformation
E. maintaining homeostasis
The correct option is maintain homeostasis which is C.
Explanation:
This is because salmon posseses adaptive physical characteristics that help it to suitably live both in freshwater and salt water. This is because homeostasis is the ability to resist any change in order to maintain body internal environment and this is a negative loop feedback. Organs of salmon work to control homeostasis but endocrine and nervous system engage more in maintain homeostasis.

Plants and other autotrophs absorb nutrients from soil and water. Autotrophs are organisms that can make their own food. The most important nutrients they need are carbon, hydrogen, and oxygen. Other nutrients needed by plants are nitrogen, phosphorous, potassium, calcium, magnesium, and sulfur.
Answer: C. Microfilaments
Explanation: Microfilaments, also called actin filaments, are protein filaments in the cytoplasm of eukaryotic cells that form part of the cytoskeleton. They are primarily composed of polymers of actin, but are modified by and interact with numerous other proteins in the cell. Microfilaments, or actin filaments, are the thinnest filaments of the cytoskeleton and are found in the cytoplasm of eukaryotic cells. The polymers of these linear filaments are flexible but still strong, resisting crushing and buckling while providing support to the cell.
