In the ovary, all eggs are initially enclosed in a single layer of cells known as a follicle, which supports the egg. Over time, these eggs begin to mature so that one is released from the ovary in each menstrual cycle.
2) cell-tissue-organ-organ system
Thus, if the cell grows beyond a certain limit, not enough material will be able
to cross the membrane fast enough to accommodate the increased cellular
volume. When this happens, the cell must divide into smaller cells with
favorable surface area/volume ratios, or cease to function.
Study of chemical composition and structure helps us to find out the differences between two samples.
The observations about its chemical composition and structure helps us to identify that the samples are two different kinds of matter because chemical composition is some what different from the physical features of the matter.
The chemical composition provides evidences about the elements from which that element is composed so we conclude that study of chemical composition and structure helps us to find out the differences between two samples.
