Answer:
The correct answer is "Orthologs are homologs found in the same species".
Explanation:
Orthologs, or orthologous genes, are defined as genes found in different species that evolved from a common ancestry. Therefore, It is false to affirm that orthologs are homologs found in the same species. Orthologous genes have the same function and often share common nucleotide sequences, however, they must be found in different species to be considered orthologs.

Answer:
Option (2).
Explanation:
The cell potential or membrane potential may be defined as the difference in the electric potential between inside and outside of the cell. The membrane potential of the cell changes during the propagation of action potential.
The resting membrane potential is -70mV. The influx of sodium ions causes the depolarization of the cell membrane. The cell potential changes from -70mV to + 30mV. The membrane potential becomes more positive during the depolarization phase.
Thus, the correct answer is option (2).
