Answer:
Hemoglobin is produced by ribosomes and transports oxygen so the mitochondria in other cells can carry out cell respiration.

Hemoglobin is a protein, and while it's synthesis is complicated, most of the synthesis of the protein is done by ribosomes.
Pros is that it helps water stay in one place and it also makes water more easily accessed for future use. The cons is animals can have less space to live and the overflow of water can occur which means flooding.
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).
