Answer:
1.concentration is of the dot is higher in the cell
2.the dots will move outside the cell where their concentration is low
3.this is an example of diffusion
Explanation:
diffusion is the movement of molecules from the region of high molecule concentration to the region of low molecule concentration
Answer:
The prime function of the GTPase activity of the G-alpha protein is to perform the hydrolysis of the attached guanosine triphosphate or GTP. Upon combination with the GTP, the G-alpha protein becomes activated, and when hydrolysis of GTP takes place to guanosine diphosphate or GDP, the G-alpha subunit becomes inactivated.
Therefore, the activity of the GTPase provides the G protein-coupled signaling mechanism's regulation. In case, if the mutation takes place within the gene encrypting the G-alpha subunit, then the inhibition of GTPase activity occurs, which would eventually result in the following outcomes:
1. The stimulation of the signaling pathway may take place for a prolonged time duration, eventually causing an unwanted differentiation of the cell.
2. There would be a spontaneous enhancement in the concentration of cyclic-AMP within the cell.
3. The activation of the G-alpha subunit would take place for a prolonged time duration.
Answer:
A. Floods will wipe out all the vegetation
Explanation:
Drought is an environmental condition characterized by scarcity of water. Less rainfall and reduced ground water levels facilitate drought like conditions. In the event of drought, animals face difficulty in finding food and water and thus are forced to migrate to other areas. However, flood is exact opposite to drought. It is caused by excess rainfall or increase in water level which destroys the ecosystem. It is not a characteristic of drought.
