Answer:
Predator foraging traits include;
- body size (mass or length),
- gape size,
- hunting or foraging mode (for example, ambush or active hunting), and
- feeding mode (for example, chewing or suctorial) .
Prey vulnerability traits include;
- body size (length and mass),
- body shape,
- defense (for example, physical or chemical protection),
- ability to avoid detection (crypsis or camouflage),
- mobility,
- ability to recognize and detect predators, and
- evasive or escape behavior (which can be elicited by physiological trait responses.
But whether or not predators engage with prey, or prey respond to predators in the first place, depends fundamentally on their relative body sizes (or predator gape and prey body shape). Pursuing prey that are too large or cumbersome can be harmful or energetically costly to predators, and pursuing prey that are too small may not be worth the energetic return.
As these populations continue to reproduce over time, the actions of natural selection can also change the species to make them better predators, or more defensive prey. Either way, this adaptation changes the entire predator prey dynamic. If one species cannot then adapt an appropriate defense, they may go extinct.

Answer:
A) action and myosin sliding past each other and partially overlapping
Explanation:
The muscle contraction occurs by the interaction between two protein filaments in sarcomeres (actin and myosin). During this process there is a “shortening” of the sarcomere, caused not by changing the length of the actin and myosin filaments, but by overlapping these filaments,
The cell produces proteins by process called translation. Proteins the moved to endoplasmic and later on they are releases by exocytosis.
