Answer:
The best answer to fill in the blank in the question: Active transport is the protein-mediated movement of substances _____, would be: Against a concentration gradient.
Explanation:
In cellular activity there are several means by which a cell may either introduce, or expell, molecules, ions, gases, waste, or water to survive. While some of these elements may enter a cell´s intracellular environment, and leave it, relatively easily, some require the help of proteins present in a cell membrane in order to either enter or exit the cell. Ions, especially, given that they are vital to maintain the cell´s capability of reacting to different stimulus, have to be particularly balanced out and controlled. In order to do so, the cells membrane possesses a series of proteins inserted between the layers that work as both gated channels and also as transporters that will allow the ions to move as they are required by the cell. Active transport then is the active passage by these proteins on the cell´s membrane of ions against their concentration gradients.
The two events described in the study are depressions and breathing-related sleep disorder. Also, the results indicate that the events are dependent.
Two events are dependent if the result of the first event will affect the occurrence or outcome of the second event, therefore changing the probability.
Answer:
A
Explanation:
Discovery science, as the name suggest, is based on observing, exploring and discovering new things. Discovery science uses inductive reasoning for scientific research. It is when an observer formulate generalizations from the observed pattern. Discovery science, in contrast to hypothesis based science, does not have a pre-defined direction. Hypothesis-based science confirms or negates an 'existing' explanation for a phenomenon.
Increased aggregate demand is an indicator of increased economic growth in a nation.
Explanation:
Economic growth of a country signifies through the purchasing capacity and the rate of demand. Increased aggregate demand of a country made the economy of a country strong and powerful. Decrease in unemployment, increase in wage opens up the way of increasing demand.
When a country be able to fulfill the demand at its level best the equilibrium takes place between demand and supply. In a perfectly balanced economic nation there is an equilibrium between demand and supply.
