In order to determine the expected average offspring length, what do you multiply with your heritability
Complete question:
In a population of toads, the average body length is 30mm. Body length is variable and the narrow sense heritability for body length is 0.1 for this population. You cross a male of 20mm with a female of 22mm. In order to determine the expected average offspring length, what do you multiply with your heritability?
30mm 9mm 0.1 8mm -9mm -0,5Answer:
The correct option is -9mm
In order to know the expected average offspring length, OABL, we need to multiply the selection differential, SD ( -9mm) with narrow-sense heritability, h² (0.1).
Explanation:
Available data:
the average body length, ABL, is 30mmthe narrow-sense heritability, h², for body length is 0.1male of 20mmfemale of 22mmTo answer this question, we need to remember how can we calculate the selection differential and the heritability in the narrow sense.
We can get the selection differential, SD, by getting the difference between the mean value of a population length, ABL, and the mean value of the parents of the next generation, PABL. So, in this example the selection differential is:SD = (20mm + 22mm)/2 - 30mm
SD = 21 mm - 30mm
SD = - 9mm
The heritability in the narrow sense, h², for body length in the population ish² = body lengths of the offspring average/selection differential
But we already know the value of h². And we want to know the body length of the offspring. So we just need to clear the following equation.
OABL = ABDL + h² ( PABL - ABL)
where,
offspring average body lengths = OABLpopulation average body length = ABL = 30mmparents average body length = PABL = 22mmSelection diferential = SD = -9mmnarrow sense heritability = h² = 0.1OABL = ABDL + h² ( PABL - ABL)
OABL = ABDL + h² ( SD)
OABL = 30mm + 0.1 ( -9mm)
OABL = 30mm + (-0.9 mm)
OABL = 21 mm
In order to know the expected average offspring length, OABL, we need to multiply the selection differential, SD ( -9mm) with narrow-sense heritability, h² (0.1).

explain the action potential steps?
Answer:
An action potential has several phases; hypopolarization, depolarization, overshoot, repolarization and hyperpolarization. ... The overshoot value of the cell potential opens voltage-gated potassium channels, which causes a large potassium efflux, decreasing the cell's electropositivity.
I hope it's helpful!
Answer:
an action potential is generated when a stimulus changes the membrane potential to the values of threshold potential. The threshold potential is usually around -50 to -55 mV. It is important to know that the action potential behaves upon the all-or-none law. This means that any subthreshold stimulus will cause nothing, while threshold and suprathreshold stimuli produce a full response of the excitable cell.
Is an action potential different depending on whether it’s caused by threshold or suprathreshold potential? The answer is no. The length and amplitude of an action potential are always the same. However, increasing the stimulus strength causes an increase in the frequency of an action potential. An action potential propagates along the nerve fiber without decreasing or weakening of amplitude and length. In addition, after one action potential is generated, neurons become refractory to stimuli for a certain period of time in which they cannot generate another action potential.

In what type of situations would random sampling (last lab) be useful?
In some types of research the target population might be as broad as all humans, but in other types of research the target population might be a smaller group such as teenagers, pre-school children or people who misuse drugs.
It is more or less impossible to study every single person in a target population so psychologists select a sample or sub-group of the population that is likely to be representative of the target population we are interested in.
This is important because we want to generalize from the sample to target population. The more representative the sample, the more confident the researcher can be that the results can be generalized to the target population.
One of the problems that can occur when selecting a sample from a target population is sampling bias. Sampling bias refers to situations where the sample does not reflect the characteristics of the target population.
