Question

*Determine whether the following statement is true or false
and then explain why in one or two sentences.*

The membrane potential results from charges moving across the membrane that has a very small effect on the concentrations of the ions, and as a result there is only a very minor difference in the number of negative and positive ions on each side of the membrane. Determine whether the following statements are true or false and then explain why in one or two sentences.

Answer #1

The statement is not entirely correct.

Generally inside the cell there are K+ ions and other negatively charged biomolecules like proteins in high concentration. On the outer side of the cell there are Na+and Cl- ions in high concentration. The membrane potential generates as there are potassium leak channels in the membrane through which K+ ion constantly moves outwards as there is a low concentration of K+ ions outside of the cell. Due to this migration there are uncompensated negative charges left inside the cell and this generates membrane potential as there is difference in charge between the both sides of the membrane.

false or rewrite the statement so that it is true.
If a scatterplot shows a linear association
between two numerical variables, then a correlation coefficient
that is close to 1 indicates a strong positive trend and a
correlation coefficient that is close to 0 indicates a strong
negative trend.

i) A p-value is the probability that the null hypothesis is
false. ii) A chi-square test statistic can never be negative.

proportion is equal to a specific value, then that specific value
will not be contained in the associated confidence interval.

a) When the mean is computed for individual data, all values in
the data set are used. b) A single, extremely large value can
affect the median more than the mean. c) One-half of all the data

Determine if the following statements are true or false. If it
is true, explain why. If it is false, provide an example.
a.) If a and b are positive numbers, then (a+b)^x=a^x+b^x
b.) If x < y, then e^x < e^y
c.) If 0 < b <1 and x < y then b^x > b^y
d.) if e^(kx) > 1, then k > 0 and x >0

Determine if the following statement is true or false. If you
believe that the statement is false, briefly explain why you think
it is false.
Small p-values of the chi-squared test of independence
indicate that the data have small amounts of dependence.
(a) The statement is true
(b) The statement is false because when the p-value of the
chi-squared test of independence is small, the results indicate
that the two variables are more dependent.
(c) The statement is false because...
