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

storchak [24]

Answer:

1/6

Explanation:

Assuming the disorder is not sex linked, Charles is a carrier so he will be Ff.

His wife Elaine can be a carrier or not because her parents must have been both Ff

Possible F1 generation for her was FF, Ff, Ff and ff. She does not have the disease.

Therefore the total chance of her having FF was 1/3 whereas Ff will be  2/3

Probability of the kid having the disease will be calculated by;

(2/3×1/4) +(1/3×0)= 1/6
