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.
For question 1. Your answer is most likely A.
And for the record. H2O is a compound.
The proteins are biomolecules which can act as hormones and enzyme catalysts which can help in catalyzing the chemical reactions. They help in the transport of the molecules and cell membrane trafficking. The proteins are antibodies which can bind to antigens and the foreign materials. The genetic information is carried by the genes in the DNA, and not proteins.
Thus, the correct answer is option 'They contain genetic information.
