Biology

Triss [41]4 years ago

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.

prohojiy [21]

Ans. (D). community.

What sort of evidence would support at least one of the components of cell theory ? a Rocks and other non-living things are not
Ksenya-84 [330]

Answer:

D

Explanation:

The correct answer would be that the origin of all cells can be traced to previous or pre-existing cells.

According to the cell theory which is made up of three parts;

  • <em>The cell represents the basic unit of all life.</em>
  • <em>All living organisms are made up of cells.</em>
  • <em>Cells do not arise spontaneously, but only from pre-existing cells.</em>

Hence, the discovery that the origin of all cells is traceable to previously existing cells supports the latter part of the cell theory.

The correct option is, therefore, D.
