Answer:
Option (4).
Explanation:
Cell membrane potential may be defined as the difference in the electric potential between inside and outside of the cell. This potential is important for the action potential.
The resting membrane potential of the cell is -70mV. This membrane potential is maintained by the potassium ions of the cell. The cell membrane are almost 40 times more permeable to potassium ions than sodium ions and makes the cell membrane potential negative.
Thus, the correct answer is option (4).
Answer:
False.
Explanation:
Salmon is one of several species of fish, typically of the salmoninae subfamily while goldfish is a type of small fish, carassius auratus , typically orange-colored.
The killer whales primarily feed on the secondary consumers in the oceanic food web.
Explanation:
Killer whales are the tertiary consumers and occupy the highest position in the ocean food web. They are predating carnivores and feed on secondary consumers like other fishes, marine animals like leopard seals, sea turtles, dolphins, sea birds, etc. These secondary consumers in turn feed on primary consumers like zooplanktons, small fishes etc which feed on the primary producers like phytoplanktons. The energy flow is highest at the primary producer level and decreases as it goes up to the consumer levels.
