Answer:
C. extinction
Explanation:
For example, you have a dog that naturally salivates at the sight of food. The salivation is an unconditioned response that is generated by the an unconditioned stimulus which is the food you present to your dog.
If you decide to ring bell before presenting food to your dog, your dog would associate the sound of the bell with food. And each time you ring the bell, your dog would salivate even when food is not presented. This salivation is a conditioned response that is generated when a conditioned stimulus (sound of the bell) is presented.
If the conditioned stimulus (sound of the bell) is presented repeatedly to your dog without the unconditioned stimulus (food), extinction occurs. Meaning your dog would stop salivating when next it hears the sound of the bell over time. The association of the sound of the bell with food by your dog would be weakened and goes to extinct over time.

1. They nurse their young with milk produced by mammary glands.
2. <span>There are international laws and treaties that protect marine mammals.
3. </span><span>Unfortunately, many marine mammals are considered endangered species and there are still threats to most of their populations, such as illegal hunting, pollution, climate change, and habitat loss.
4. T</span><span>hey have adapted to living all or part of their life in the ocean.
5. </span><span>To keep warm in the ocean, most of them depend on a thick layer of blubber (or fat).
6. </span><span>To be able to stay under water for long periods, they store extra oxygen in their muscles and blood.
7. </span><span>They also have more blood than land mammals in proportion to their body sizes, can direct their blood flow to only their vital organs (such as their heart and lungs), and can slow their heartbeat down so they are using less oxygen in a dive.
PART 2
