Substrate Concentration I believe
Answer:
True
Explanation:
The species that went extinct could be a food source for another and that would possibly be detrimental to the chain.
The neutralization reaction is written as:
LiOH + HBr = LiBr + H2O
0.253 mol LiOH / L solution ( .01673 L solution ) ( 1 mol HBr / 1 mol LiOH ) = 4.233 x 10^-3 mol HBr
Concentration of HBr solution = <span>4.233 x 10^-3 mol HBr / .01 L solution = 0.423 M HBr solution</span>
Answer: positive sodium ions
Explanation:
This relates to the Action Potential which is what a nerve cell goes through when it needs to send information down the nerve cell to another cell and so on till it gets to the destination of the message.
The information is transmitted when the segments of the axon fire and when they do, positive sodium ions come in from outside the cell to the inside thereby making the inside positive. The previous segment would return to a resting potential when potassium ions which are negative, rush into the cell.
The idea that all living things are composed of cells and that all cells come from other cells defines the cell theory.
Hope this helps! :)
