Answer:
D) integrins
Explanation:
The extracellular matrix is an intricate network of carbohydrates and proteins in the cells extracellular space. <em>Collagen proteins </em>undergo modification with carbohydrates within the cell to form collagen fibers; they are interwoven with proteoglycan complexes is made up of carbohydrates proteins and polysaccharides. The resulting mesh is capable of providing structural integrity, mechanical strength and support to tissue.
In the ECM, the fibers are joined to integrins by fibrobronectin bridges. Integrin proteins form crucial connections between surrounding cells, are embedded within the cells' plasma membranes and anchors them in the ECM. Also, they facilitate cell communication in the environment- <u>they are capable of detecting mechanical and chemical signals</u> from the ECM and respond by stimulating signal pathways inside the cell.

Answer:
Based on this, you know that Sampson is using the whistle as a <u><em>secondary </em></u> reinforcer to train the dolphins.
Explanation:
Secondary Reinforcement can be described as a condition in which a stimulus initiates a behavior after being previously associated with a primary reinforcer. A secondary reinforcement is a stimulus that satisfies basic survival instinct such as food, drinks, and clothing.
The same phenomenon was being used by Samson to train his dolphins to perform tasks. The dolphins enjoyed the sound of the whistle because previously that sound was paired to them getting their food.

Qualities that have nothing to do with genetics are dependent on an organism's environment and the organism's genetics do not play a role in determining them. For example, if a person's finger is cut off, this is a trait that is independent of genetics. The loss of a finger will not be inherited into the organism's offspring.
Traits that are dependent on genetics are those such as eye color and height.
