This is because not all genes are expressed at the same time, so not all the proteins are present at a certain moment. The mechanisms that cell uses to control gene expression are called regulation of the gene expression. Thanks to regulation of the genes, cells have the ability to increase or decrease the production of specific gene products such as proteins. This property is important for the adaptability of an organism because it allows the cell to express protein when needed.
Herbivores. The eat directly from the producers. 10% of the producer's energy goes to herbivores, while only 10% of the 10% energy the herbivores had goes to carnivores.
It is the serous membrane
Both use oxygen, both produce energy, both give out carbon dioxide as the result and the overall chemical reactions are the same.
Hope this helps :)
Once an egg is fertilized by a sperm, a zygote is formed. The zygote divides into multiple cells in a process known as cleavage, triggering the beginning of embryonic differentiation. ... Cells in these three layers will give rise to different parts of the organism. The endoderm eventually becomes the gut.Mar 3, 2011
