The correct options are B and C
B) Natural-born citizenship can be determined by location of relationship.
C) Collective citizenship occurs when the U.S. acquires a territory.
For example, a child born in the United States is considered a US citizen. Also, the population of any terrority that is acquired by the US become the citizens of the US. For example, the people of Alaska became US citizen when it was purchased, or the people of Puerto Rico, who cannot vote but are still considered citizens.
Answer:
Explanation:
Action potential
It is the potential or power or electrical energy required to generate impulses and provides communication between the neurons is called action potential. Normally cell membrane consists of potential is called resting membrane potential() -70mV. The action potential is due to exchange of different ions across the membrane.
Phases of the action potential in a neuron are
i. Depolarization- it is caused by the influx of sodium and calcium ions through the opening of voltage-gated sodium and calcium channels. sodium ion influx is rapid than the calcium ions membrane potential -70mV to +30mV.
ii. Repolarization - It causes the efflux of potassium ions into the cell through the opening of potassium channels. the membrane returning to resting membrane potential.
iii. After- Hyper polarization - in this stage the potassium channels remain open and causes re polarization and comes to normal membrane potential.
The generation of impulses(depolarization) in neuron mainly depends on influx sodium and calcium ions without these ions, no action potential developed and neuron firing does not occur.
If the drugs inhibit these channels, no depolarization, no action potential, no neuronal firing or communication.
The channels involved in an action potential are voltage-gated sodium channels, potassium channels, and calcium channels.
The action potential is required for transmission of information one are to another area in the body.
The responses to different stimuli is due to action potential.
Answer: C. The company might fear that the letter-writing campaign will become a boycott if it doesn't respond.
Explanation:
A letter-writing campaign might be a precursor to larger things such as a boycott and this is alone to ensure that companies pay attention to the concerns of those writing the letters.
The logic is simple. If the organizers of the people writing the letters could organize so many people to write letters, they could just as well organize these people to boycott the company if they do not get their way and this would be harmful to the business.
