The differentiation is based on a set of activation / inactivation of genes (parts of DNA) via complex cascades of regulation. We can not consider a differentiating cell individually. Indeed, its "expression profile" depends on its environment: cell-cell interactions, cell-matrix. It is these extra-cellular signals that will trigger the internal regulation signals. The establishment of plans for the organization of a Drosophila embryo or the development of limb buds in mice are well-known models. In these models, so-called "positional" information plays a large role: a substance present in the form of a concentration gradient in the extracellular medium will trigger or not intracellular signals depending on the dose at which the cells are exposed along this gradient.
Answer:
They are formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.

Answer:
glucose-6-phosphate
Explanation:
Glycolysis is metabolic pathway which converts glucose into pyruvate. The energy released from the process is used to form high-energy molecules known as ATP and NADH.
Glycolysis is the sequence of ten reactions which are enzyme-catalyzed.
<u>Sugars are majorly connected to glucose-6-phosphate which is formed from the phosphorylation of the glucose units.</u>
<u>Fructose-1,6-bisphosphate
, dihydroxyacetone phosphate and phosphoenolpyruvate are further produced or used in the process and hence are not linked directly to sugars.</u>
Answer: A storm or tornado
Explanation:
Answer:
6 months
Explanation:
First, we must remember that doxycline has an effect only on nematodes, but it cannot effectively prevent microfilariae presented before treatment in the blood of the infected. What we can conclude from this is that it is possible that microfilariae grow and develop, however they will not be able to reproduce, since W. bancrofti is completely dependent on Wolbachia for replication. With that, the microfilariae are running out of time and with about 6 months the patients are free of any trace of microfilariae. So we can conclude that 6 months is the longest time that microfilariae survive in circulation.
