Surface tension allows light insects to walk on water.
The huckleberry patches will provide a very high level of consumption efficiency.
<h3>What is consumption efficiency?</h3>
Consumption efficiency refers to the ability of a consumer to be able to derive the maximum level of consumption from a given resource or group of resources.
The huckleberries depend on the animals such as Bears as well as other herbivores for seed dispersal and propagation. These plants have therefore, develop efficient means to encourage dispersal by these animals. The seeds of the Huckleberries are enveloped in sweet, nutritious fruit that is comparatively undefended.
Therefore, the Bears and other herbivores will derive a very high level of consumption efficiency from the Huckleberry patches.
In conclusion, consumption efficiency measures the ability of a consumer to derive maximum consumption. High consumption efficiency implies that the resource provides a great deal of benefit and satisfaction to the consumer.

The right answer is <span>Refractory period.
At the moment when the action potential is emitted, the fiber being depolarized, it is impossible to depolarize it again. It is, therefore, necessary to wait until the membrane potential returns to a value below the critical threshold in order to be able to excite it again. We are thus led to distinguish two periods that characterize its excitability.
An absolute refractory period: during which any stimulation, even supraliminal, is ineffective since the fiber is already depolarized.
A relative refractory period: during which a second action potential can be omitted provided that the depolarization produced by the excitation reaches the critical threshold, which implies that it is more important since the value of the resting potential has not been restored yet.</span>
Positive feedback is a control system that sends a signal to ( increase) a response.
Divergence of crustal plates. I could be wrong though and if I am my bad :))
