Different finch species have beaks of different shapes and sizes. What do these beak differences tell us?

Biology
1 answer:
Kruka [31]3 years ago
8 0

Answer:

Differences in beak shapes tell us that all the finches eat the same type of food. Different finch beak shapes are evidence that all Galápagos finches shared a common ancestor a long time ago. Different finch beak shapes are evidence that over time, finch species adapted to different food sources on the islands.

The stimulation of an inadequate number of sodium channels for the generation of a positive sodium channel feedback loop is cons
diamong [38]

Answer:

Sub-threshold

Explanation:

If the stimulus is too small to generate the action potential, it is considered as subthreshold stimulus. Subthreshold stimulus causes the opening of small number of sodium channel i.e. not enough to generate action potential because action potential is generated by complete reversal of membrane polarity. Slight depolarization is caused by subthreshold stimulus by the opening of inadequate number of sodium channel but its magnitude is not enough to reach the threshold voltage. Consequently the action potential is not generated.

The response produced by subthreshold stimulus is called as local response or local depolarization because it could not travel further. The minimum stimulus required to generate the action potential is call as threshold stimulus and stimulus greater than threshold stimulus is called as suprathreshold stimulus. It changes the frequency of generated action potential.

Which trophic level contains more energy: a trophic level of herbivores or a trophic level of carnivores? Why?
Bas_tet [7]
Hello :)

The answer to your question is a trophic level of carnivores


Only a fraction of the energy available at one trophic level is transferred to the next trophic level.

Since carnivores are above herbivores in the trophic levels, herbivores have more energy than carnivores.

Hope this helps and have a great day!
