Answer:
undergo no changes in strength, speed, or duration
Explanation:
A specific electrical signal being transmitted to a neuron is sufficient to generate an action potential. This happens because of the spread of a nervous impulse.
The stimulation of a neuron follows the law of all or nothing. This means that either the stimulus is sufficiently intense to excite the neuron, triggering the action potential, or nothing happens. There is no stronger or weaker action potential; it is equal regardless of the intensity of the stimulus. The smallest stimulus capable of generating action potential is called the threshold stimulus. In this case, if the magnitude of the received electrical signal doubles, the action potential will not change in strength, speed or duration.

Explanation:
Which of the following contradictions best exemplifies why the Democratic Party struggled during the 1928 presidential election?
A. It tried to appeal to religious fundamentalists along with committed secularists.
B. It promoted Jim Crow laws but saw an influx of African American voters to its districts.
C. It was forced to publicly endorse Prohibition despite the objections of big businesses.
D. It relied on the support of both the Ku Klux Klan and Roman Catholic immigrants.
The Democratic Party's struggle in the 1928 presidential election was best exemplified by its divided stance on Prohibition, reflecting deep conflicts between urban "wets" and rural "dries" which hampered the party's electoral success.
Explanation:The Democratic Party faced significant internal conflict during the 1928 presidential election due to a fundamental contradiction exemplified by their need to cater to diametrically opposed constituencies: urban, northern "wets" who opposed Prohibition and rural, southern "dries" who were in favor of it. This tension within the party undermined their unity and opened the door for Republican ascendancy during the era. Moreover, while the party attempted to avoid the contentious issue of slavery, it struggled to maintain harmony between diverse voter bases, particularly as different regions and social groups had conflicting interests and priorities.
In the context of the options provided and the historical setting, the most accurate contradiction that exemplifies the Democratic Party's struggle during the 1928 presidential election is option C - the party was forced to publicly endorse Prohibition despite the objections of big businesses and urban constituents.
Dr. Williams conducted a survey in the mall, measuring the shopping habits of people ages 15, 25, 35, 45, and 55, with 10 people in each group. Which of the following best describes her study? an experiment a cross-sectional study a case study a longitudinal study a double-blind study
Answer:
A cross-sectional study
Explanation:
The best fit would be cross-sectional study, for one because it is observational, meaning there is no manipulation of variables like you would find in an experiment. Secondly, it is comparing populations within different groups, in this case age groups. Although, this can also be done through a longitudinal study, but as the name suggests, it is longitudinal so it is done over longer periods of time.
Answer:
A cross-sectional study
