What feature of the skeleton eventually allow a child to maintain balance while walking and running?

Biology
1 answer:
Triss [41]3 years ago
5 0
The vertebral column, when seen from the side, has 4 curves: 2 convex curves (cervical and lumbar curves) and 2 concave (thoracic and sacral curves). This curves are the feature of the skeleton that allow a child to maintain balance in the upright position eventually.
When we are born we have a single concave curve throughout the whole vertebral column but, as we grow, still in the early months as we try to hold our head, the cervical curve starts to develop, and later, as we try to sit up, stand up, and walk, the lumbar curve aslo starts to develop. In few years we have all curves fully developed.

What can be done in the future for the greenhouse effect?
andrezito [222]

Second thoughts:

I don't think doing anything in the future will be of use, because we should have already done it, and we didn't, so we have to do it now.

And what we should do is:

To find and actually use and apply new energy sources.

To do more (or less, depending on what the problem is).

To clean the mess we have done / recover the gap in the ozone layer /fix the damage that we have caused.

If you're interested:

I don't think protesting (like we're currently doing) will be of help for two simple reasons:

1. - I don't know for sure, but I don't think politicians care, like or pay attention to protests (unless it's something like the Yellow Jackets).

2. - The time we spend protesting is more valuable than we think. We should leave that aside.

Hope it helped,
