Lungs
Amphibians are known to be animals which can survive both on land and in water. They can walk on land and have limbs to swim. However, they do not have gills to breath but can only breath directly from air through lungs while bony fish have fins to swim in water and can breathe through there gills and filter oxygen from water.
Answer:
-70 mV
Explanation:
Given that Neuron A and Neuron B interact with Neuron C
Neuron A produces ; - 2mV of IPSP and fires 6 times
Neuron B produces ; 3mV of EPSP and fires 4 times
Resting potential = - 70mV
threshold = - 50mV
The resulting membrane potential in neuron C
= -70 + 6(-2) + 4(3)
= -70 - 12 + 12 = -70 mV
Answer:
Both extract from the soil while difference in their extraction method.
Explanation:
Harvesting food crops similar to mining because both are gained from the soil whereas it is also different from mining due to their method of extraction. Seeds are grown again and again in the soil and other agronomic activities has to be done to gain good yield of the crops while on the other hand, in mining precious metals is to be extracted that is already present in the soil.
