I think that about half of all babies are able to walk independently by 12 month of age. It said that babies tend to take their first steps from the age of 9. Babies usually start to crawl before they can walk. This is because their arm are usually more effective. After crawling they learn to stand up with their feet first and later learn to walk while holding things. The next step after that is walking.
Not all babies walk at the same time. There those that learn before the other so there is no need to worry if your child does not walk by 12 months.

This relationship between the plant and the animal represents mutualistic symbiosis; they have a symbiotic relationship which is mutualistic.
Plants benefit by having their seeds dispersed to farther areas when animals eat their nutritious fruits. So, animals gain from the plants since they are able to attain nourishment for themselves. Both benefit from each other at the same time when an action is done, and so, their relationship is mutual.
