Answer:
-35 mV and +56 mV
Explanation:
The membrane potential is the energy that is needed to drive membrane changes across the phospholipid bi-layer membrane.
Ions can move in and out of the cell through protein channels. The movement of the ions is as a result of concentration that affect the operation of ion gates.
The reverse potential is given by the Nernst equation:
where, R = gas constant
T = temperature (Kelvin)
z = ion charge
F = Faraday's charge
The potential is calculated and the result is -35 mV and +56 mV respectively.
The invention of the cotton gin was a revolution in the cotton industry. Due to the manner in which this sector was exploited in the US, it led to a large increase in slavery in the Southern states, in order to meet the constantly growing demand for cotton using a larger workforce.
Hope this helps!
Answer:
1. Slavery
The South relied on slavery for labor to work the fields. Many people in the North believed that slavery was wrong and evil so they wanted slavery to be illegal throughout the United States. This made wealthy landowners in the South fearful that their way of life would come to an end.
2. States' Rights
Since the Constitution was first written there had been arguments about how much power the states should have versus how much power the federal government should have. The southern states felt that the federal government was taking away their rights and powers.
3. Expansion
As the United States continued to expand westward, each new state added to the country shifted the power between the North and the South. Southern states began to fear they would lose so much power that they would lose all their rights.
****While there were many political and cultural differences between the North and the South that contributed to the American Civil War, the main cause of the war was slavery.
The correct answer is B. Aggregate
Explanation:
The meeting and interaction of two or more people are frequently called a social group. However, there are different types of groups depending on the way the people that are part of the group interact and are organized. In the case of aggregate individuals or collection, there is no cohesion, interaction or sense of unity between the individuals that are gathered. This means an aggregate is just different individuals that gather at the same and place but who do not interact or think about the others as a group, for example, the people waiting for a bus in a bus stop are considered as aggregate. This type of group is different from primary or secondary social groups as there is not any type of relationship, common goal or shared features between different people. Thus, if people gather in the same place at the same time but lack organization or lasting patterns of interaction they form an aggregate.
