Biodiversity tends to clump around the equator, as it has more heat. The closer you are to the equator, the more biodiversity you will find. The polar regions have little to no life.
The lymphatic system destroy harmful substances 'By producing antibodies'.
The lymphocytes contained in lymphatic organs are produced with other defence cells by the bone marrow. They are then dispersed to eliminate pathogens.
No, the answer is false.
A salad would be an example of a mixture, as it is a blend of tomatoes and lettuce.
A salad would be considered a heterogeneous mixture (you can see its different components).
Answer:
Generally, K+ ions ensures re-polarization of the membrane potential. It always ensures that the neuron returns its resting state, protecting the neurons and ensuring episode of rest before the next action potential.
K+ does this by leaving the axon, making the inner layer more negative. This is resting membrane potential. Because there are many K+ channels for leakages out of the neuronal axons.
Therefore, in this scenario, he neuron will return to its resting membrane potential state which between values -50 to -75mV.
Therefore the value of the potential will be -60mV, or within the range of -50 to -60mV. This is because the neuron is is non- excitable.
