diffusion

Materials move within the cell 's cytosol by diffusion, and certain materials move through the plasma membrane by diffusion. Diffusion expends no energy. On the contrary, concentration gradients are a form of potential energy, dissipated as the gradient is eliminated.

RUDIKE [14]

Answer:

The correct answer is C. co-evolution

Explanation:

When two or more species evolution is influenced by each other and are interdependent than this type of evolution is known as co-evolution. There are several examples of co-evolution like predator-prey co-evolution, flowering plants and pollinators evolution, etc.

The predator-prey evolution is famous in which there is selective pressure on prey to evolve to avoid getting hunted and the same pressure is on predator to evolve with prey so that they can get their food and survive. Therefore the correct answer is co-evolution.

<h3>What is Mike Velings talks about?</h3>

Industrial aquaculture has had a wide range of negative effects on the environment, including the overfishing of wild fish to feed carnivorous farmed fish and the escape of farmed fish from their containment, which endangers local wild fish populations.

Lastly, in the words of Mike Velings, We are approaching a worldwide food crisis, he said. At our current rate, we are already taking more fish from the ocean than it can naturally replace, despite the fact that almost 3 billion people rely on the ocean for their food. Mike Velings, an entrepreneur and conservationist, offers a solution in this fact-filled, eye-opening talk: the practice of farming fish. "We need to stop hunting the ocean and start farming it,"
