<em>The correct choice is option B. Growth</em>
The American demographer Warren Thompson observed changes, or transitions, in birth and death rates in industrialized societies over the previous 200 years, as a result of such observations he proposed, in 1929, a theory called Demographic transition (DT). This theory explains the transition from high birth and death rates, in pre-industrial economic systems, to lower birth and death rates in industrialized economic systems.
This demographic transition theory involves four stages. Specifically,<em> the second stage is characterized by a fall in death rates due to improvements in food supply and sanitation, which leads to an increase (or growth) in population as well as in life expectancies. </em>
The answer to the question above is FALSE. Not all deliberate acts stems all conflicts. It depends on the purpose of the action being done, If the deliberate act will lead to conflicts which is undesirable to ones party it will be a conflict but if the deliberate action is purposely for the betterment then it will lead for the betterment and non-conflict situation.
There are numerous likenesses and differences between religious conventions in this period. For instance, a few religions, for example, Hinduism were polytheistic while others, for example, Zoroastrianism were monotheistic. Confucius featured the significance of education, while Daoism was against it; some had their prophets or divinely guided figures (Confucius) while some did not (Hinduism). Nonetheless, they all had some composed record clarifying their thoughts; "analects", "vedas", "upanishads", and so forth. They all had a divine being from which they believe their religion originated, “God”.
In the age of identity theft, customers feel that marketers are violating their privacy when they: <span>resell information from marketing surveys without permission
information from surveys often carry sensitive topics such as age, address, total salary, or even social security number.
Selling this to another party without consent is considered an unethical practice.</span>
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.
