Answer:
Through the process of natural selection, sea urchins have developed spines that serve as a defense mechanism against predators and a means of anchoring themselves in turbulent waters. This adaptation allows them to better survive in their environment, with individuals possessing longer or stronger spines being more likely to pass on their genes to the next generation. As a result, the population of sea urchins gradually becomes better adapted to their surroundings, demonstrating the power of natural selection in shaping the evolution of species.

When first placed in the dirt, the worms may burrow into the soil or crawl around on the surface.
Exploration.
Less crawling around.
Motionless on the soil.
Tunnel creation.
Visible casting.
What are the likelihoods of worm behavior?After 2 minutes, the worms may still be exploring their new environment or starting to burrow deeper into the soil. After 5 minutes, the worms may have burrowed deeper into the soil or be crawling around the surface less frequently. After 10 minutes, the worms are likely to have burrowed deeper into the soil or remain motionless on the surface.
When returning after one day, you may notice that the worms have created tunnels in the soil and have consumed some of the organic matter in the soil. They may also have deposited their castings, which are rich in nutrients. When returning after two days, you may notice that the worms have continued to create tunnels and consume organic matter, and their castings may be more visible.

a cost benefit analysis balances the cost of an action against what
A cost-benefit analysis balances the cost of an action against its benefits.
It is a systematic process used to evaluate the pros and cons of a decision or project by comparing the expected costs with the expected benefits.
The costs can include financial expenses, time, resources, and any negative impacts incurred as a result of the action. On the other hand, the benefits encompass the positive outcomes, advantages, or gains derived from the action.
By assessing and quantifying both the costs and benefits, a cost-benefit analysis helps decision-makers determine whether the benefits of undertaking the action outweigh the costs and whether it is economically viable or beneficial to proceed with the proposed course of action.
