It greatly increases the surface area which makes more space for all of the complexes of the electronic transport system.
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.
<span>D is the correct answer. In the F2 generation, 1 in 4 plants have two alleles for the dominant trait, 2 in 4 have one dominant and one recessive alleles and 1 in 4 has two alleles for the recessive trait.</span>
