Hi!
During protein synthesis,
introns are removed.
and
exons are joined.
So, B.
The given blank can be filled with cells.
The extracellular matrix is the protective tissues present as a coating of the cells. Both animals as well as the plant cells have the extracellular matrix, this coating provides support, biochemical protection and mechanical protection from the external environment of the cells. In the plant cells, the cell wall is a type of extracellular matrix.
Answer:
I would start on Evaporation. I will then have to go through condensation, then precipitation, then a surface runoff then into groundwater which will start the evaporation process all over again :)
The convergent evolution may cause the arising of the similar traits in distantly related species. These traits may arise due to the demands during the course of evolution, the reason for having a different origin may be that it was not required initially, but required later. The bones of the birds and the bat are homologous in structure, but the origin of the wings are different.
So, these characters represent a type of convergent evolution.
