Evolution :).
Descent with modification helps to explain anatomical similarities among certain species. The bones of the forelimbs of humans, cats, and bats (you can add in penguins, alligators, and more) are used in different ways but have similar structures.
The best explanation is that these animals have a common ancestor. With new generations, new species emerged by natural selection from different populations, and with this, the bones become better for different tasks.
The forelimbs and other such structures with anatomical similarities due to a common ancestor are called homologous structures.
Pollen can be carried to multiple flowering plants by animals called pollinators, which can be bees, birds, spiders, or even small mammals!
It would better your city. The city would look way nicer and a lot of people would probably enjoy a recycling program. For the reasons of having reused items so the dump won't be as bad and it would give more jobs and be a healthy way of discarding old paper and bottles. It could easily help out your city. The recycling program would be a great idea and I hope it could happen.
I hope this is what you wanted.....

3. Adhesion is correct ... looked in my bio book sorry
All of them. Forests are considered natrual enviornment and people/buildings are man-made environment
