Answers

Answer 1

the decline of the Federalist Party.
an increase in John Adams’s power.
stricter laws about campaigning.

Answers

Answer:

An increase of John Adams power.

Explanation:

A long-term effect of the election of 1800 was an increase in John Adams’s power. The correct option is C. The twelfth amendment, requiring separate electoral votes for president and vice president, was the only constitutional modification brought about by the election of 1800.

What was John Adams's main achievement?

Adams regarded the successful resolution of this crisis as his greatest achievement as president. The Convention of Montefontaine, signed in October, put an end to hostilities between France and the United States.

The Democratic-Republican nominee, vice president Thomas Jefferson, defeated the Federalist Party nominee, president John Adams, in what is sometimes referred to as the "Revolution of 1800." An era of Democratic-Republican leadership was inaugurated by the election, which served as a catalyst for political realignment.

The ability of John Adams to unite Americans behind the cause of independence was his greatest accomplishment, even though he would later go on to become the second President of the United States in 1797.

what are some ways in which the sahel is different from the tropical wet zone

Answers

Answer:

Explanation:

The Sahel is the area between Sahra (on the north) and savanna in Sudan (on the south). The climate of this area is usually dry and windy, with very short rainy periods. Weather is warm, and during the hottest periods, it can go even up to 97 and 108 °F. Yet, winters are usually quite warm as well – even during the cold period, the temperature doesn't go lower than 59 or 70 °F. The weather is mostly sunny, meaning there is sunshine up to 80% of daylight hours.

Tropical Wet climate is typical of the area around Equador, though not the whole belt, but only some parts of Brazil. Congo, Indonesia, and the Philippines. While the weather is also warm, there is prevailing rain during the whole year. Sometimes, rain falls every day. While the temperature is warm, it never is as hot as it can get in the Sahel. Temperature is always around 80 °F, while year-round, without much change. What is also different is that in the Tropical wet climate area it may seem as if the weather is warmer because of high humidity.

Therefore, the main differences are

Shael is very dry, while the tropical wet zone is rather humidWhile both areas are warm, the Sahel zone has more changes in temperature degree than the places where there is a tropical wet climateTropical wet climate is characterized by almost daily rainfalls, while in Sahel area, rain seasons are short and rare

What is Infanticide?

Infanticide is the deliberate killing of children or other newborns. Infanticide was a common practice that was primarily used to eliminate undesired children throughout human history.

Its major goal was to stop resources from being spent on weak or defective offspring. Unwanted infants were typically left to fend for themselves and perish from exposure, but in certain communities, they were killed on purpose.

Infanticide was a common practice in most Stone Age human communities, and estimates of the percentage of children killed by infanticide during the Mesolithic and Neolithic eras range from 15 to 50%.

In the first millennium, both Europe and the Near East outlawed infanticide.

Since infanticide was prohibited by Christianity from the beginning, Constantine the Great and Valentinian I decided to outlaw it throughout the Roman Empire in the fourth century.

The Phoenicians, based on a narrow coastal strip of the Levant, put their excellent seafaring skills to good use and created a network of colonies and trade centres across the ancient Mediterranean. Their major trade routes were by sea to the Greek islands, across southern Europe, down the Atlantic coast of Africa, and up to ancient Britain. In addition, Arabia and India were reached via the Red Sea, and vast areas of Western Asia were connected to the homeland via land routes where goods were transported by caravan. By the 9th century BCE, the Phoenicians had established themselves as one of the greatest trading powers in the ancient world.

What are some ways that intercessory prayer makes a difference in the lives of others?











(my answer)


There is only one Intercessor to God the Father, and that is via His Son, Jesus. When you pray, you are to ask the Father in Jesus' name. In John 16:23-23 we read, "And in that day you will ask Me nothing. Most assuredly I say to you, whatever you ask the Father in My name, He will give you. Until now you have asked nothing in My name. Ask, and you will receive, that your joy may be full."

There is no other name under Heaven where we may come to the Throne of God and ask for our needs. All humans die and return to the ground/grave (hell). We all 'sleep' until the time of our Resurrection as the Scripture is clear on.
