If there is a logarithmic relationship between stimulus intensity and action potential frequency in sensory neurons, how much wi
frez [133]

Answer:

The action potential rate will be doubled

Explanation:

The logarithm of a number for a given base is the power to which the base must be raised to give the number. Logarithm of a number can be in different bases. The base of common logarithm is the base 10.

For example, logarithm of 1000 to base 10 is 3 because 10 raised to power 3 equals 1000

Log₁₀1000 = 3 since 10³ = 1000

Therefore, if there is a logarithmic relationship between stimulus intensity and action potential frequency in sensory neurons and the stimulus intensity increases by 100, the action potential rate will increase thus:

Log₁₀100 = 2

Therefore, the action potential rate will be doubled

<h3>What does the biological term replicate mean?</h3>

Reproduction is the process of producing descendants. The two basic types of reproduction are sexual and asexual. A sexually reproducing organism is genetically different and has the genetic information of both of its mothers. Genetically identical children are produced through asexual reproduction by having each parent repeat itself.

<h3>What is the name of the reproductive process?</h3>

Reproduction is the process by which new individual creatures, or "offspring," are produced from the "parent" or "parents" (or procreation or breeding). Reproduction is a fundamental element of all known life, and it is the reason that every single organism exists.
