The
infected papaya trees will produce less carbohydrates or chemical energy for the toucan. If there were fewer carbohydrates within each papaya, the
toucan's muscle cells would not be able to obtain as much chemical energy as
they normally do. This chemical energy will be converted into mechanical energy
or heat flow, which the toucan uses to fly.
Therefore, the lower amount
of mechanical energy and heat flow from the muscle contractions, it would
result into a reduced amount of kinetic energy of motion when the toucan is
flying.
Mitochondrion is found outside of nucleus in animal cell .
So , i think the answer is B.
During exercise there is an increase in physical activity and muscle cells respire more than they do when the body is at rest. The heart rate increases during exercise. The rate and depth of breathing increases - this makes sure that more oxygen is absorbed into the blood, and more carbon dioxide is removed from it.
