Los hebreos, establecidos en Canaán, se dedicaron a la agricultura y la ganadería. El cultivo característico era el olivo y la vid, también obtuvieron legumbres y lentejas. El pastoreo de ovejas, bueyes, cabras, caballos y camellos acompañaba la actividad agrícola
The "Cold War" had that name because the two superpowers (the USA and USSR) did not fight a direct "hot" war against one another. They engaged in a protracted stand-off against each other, and had an arms race of nuclear weapons and military strength. They also supported "proxy wars" where they took opposing sides in conflicts happening in other parts of the world (such as the Six Day War in the Middle East).
Further detail:
Some of the deeper issues that caused rivalry and tension between the United States of America (USA) and the Union of Soviet Socialist Republics (USSR) were that the USA was committed to capitalism and democratic institutions of government, whereas the USSR was committed to communism and imposed authoritarian government. The Cold War was mostly a tension between these worldviews.
There were also immediate conflicts and pressure points as the Cold War began in the late 1940s (after World War II). One of those issues was that the USA had atomic weapons and the USSR did not. (The US would not share that technology with the Soviets, who had been their ally in World War II.) When the Soviets developed their own atomic weaponry, this led to a massive arms race between the superpowers -- which brought significantly more tension to the situation. Further tensions developed over which nations would be aligned with each of the superpowers -- either with the USSR and communism and with the USA and its democratic, capitalistic worldview. And (as mentioned above), the two superpowers aided differing sides in conflicts that took place in various parts of the globe during the Cold War years.
Manifest Destiny was a philosophy that considered the United States was divinely ordained, justifiable and inevitable to expand its borders.
This philosophy encouraged the convergence of social, economic, and political factors helped urge the speed of westward expansion in the 19th century. With the Louisiana Purchase in 1803 people were driven to the west, white settlers and proponents of expansion began to voice concerns over what they considered an obstacle to settlement - The American Indian tribes that lived there -. White settlers considered the lands east of the Mississippi River a great place to raise cattle, wheat, and cotton.
The convergence of Manifest Destiny and the need to expand was used to rationalize the removal of American Indians from their native homelands. The Indian Removal Act of 1830 was signed into law and authorized the president to reserve land west of the Mississippi River and exchange it for Native American land to the east of the Mississippi.
The two sides in the american revolution were british army and their colonial loyalist supporters as well as the american revolutionary forces
Answer:
B) action potential
Explanation:
The ions continuously flow across the cell membrane in the cells which establishes a membrane potential across the membrane. The cell membrane tries to maintain the negative potential between -40 to -90 mV.
At rest the neuron cell maintains the membrane potential around -70mV and this potential are known as the resting potential.
When the positive ions especially sodium ions enter the neuron then the positive charges get accumulated inside the cell. This changes the potential to a more positive value and when it crosses the threshold of -55mV then an action potential is formed.
In the given question, if the membrane potential changes from –70 to +50mV then an action potential will be generated in the neuron cell.
Thus, B) action potential is the correct answer.
