What did Donald C. Johanson and Tom Gray discover in 1974?

Answers

Answer 1

"The correct answer is that Donald C. Johanson and Tom Gray discovered the fossilized skeleton of a hominid nicknamed ""Lucy"" in 1974.

In 1974, paleoanthropologist Donald C. Johanson and his graduate student Tom Gray were conducting field research in the Afar Triangle region of Ethiopia.

During their expedition, they made a groundbreaking discovery when they uncovered a significant portion of a fossilized hominid skeleton. This skeleton, which was approximately 40% complete, belonged to a species now known as Australopithecus afarensis.

The discovery was named ""Lucy"" after the Beatles' song ""Lucy in the Sky with Diamonds,"" which was playing in the camp at the time of the find. Lucy's discovery was monumental because it provided valuable insights into human evolution.

The skeleton's combination of ape-like and human-like features suggested that Australopithecus afarensis was an upright walker, yet still had some arboreal capabilities.

Lucy's age, estimated to be around 3.2 million years old, made her one of the oldest and most complete hominid skeletons ever found. This discovery has been instrumental in understanding the evolutionary history of humans and has contributed to the ongoing research into the origins of our species

How was the scientific method of exploring ideas different from looking to history for answers

Answers

The Scientific Method of exploring ideas is different from looking to History for answers because the scientific method is basically exploring and investigating NEW ideas unlike if you look at history for answers you are just looking for answers from the past.

Final answer:

The scientific method uses observations, hypotheses, and experiments to test and refine knowledge, while historical methods rely on historical records to understand human events over time. The scientific method has driven technological advances, yet has limitations in some disciplines and non-material phenomena.

Explanation:

The scientific method differs from historical methods of understanding the world by using a specific, systematic approach to explore questions. This includes making observations, creating hypotheses, and conducting experiments which are repeatable and can lead to further hypotheses and observations. In contrast, historical analysis often looks to the past to understand the present, relying on the interpretation of historical records, artifacts, and other sources to draw conclusions about human activities, societies, and events over time.

While historical methods are valuable for understanding context and development, the scientific method is designed to test and refine knowledge through empirical evidence and controlled testing. It can be applied to various disciplines, but its applicability may be limited in fields where it is challenging to conduct repeatable experiments, such as archaeology or psychology. Ultimately, the scientific method has been the foundation responsible for significant technological advances over the last 500 years, although it is not without its limitations when it comes to non-material phenomena.

Which railroad company was responsible for building from the middle of the united states westward?

Answers

the answer for this usa test prep video is Union Pacific 
Final answer:

The Union Pacific Railroad built from the middle of the United States westward, from Omaha, Nebraska. Under the Pacific Railway Act, it was commissioned with the Central Pacific Railroad to complete the transcontinental railroad to facilitate travel and the transport of goods nationwide.

Explanation:

The railroad company that was responsible for building from the middle of the United States westward was the Union Pacific Railroad. In the mid-19th century, the U.S. government passed the Pacific Railway Act which commissioned the Union Pacific Railroad to build new track west from Omaha, Nebraska. This was part of a broader initiative to create a transcontinental railroad, with the Central Pacific Railroad working from the West Coast eastward. The initiative was a significant venture in the era of railway expansion in the United States, promoting settlement, commerce, and industry development.

The Union Pacific Railroad, heading west, and the Central Pacific Railroad, heading east, eventually connected their tracks at Promontory, Utah, in 1869, completing the first transcontinental railroad. This accomplishment played a crucial role in facilitating travel and distribution of goods across the country, linking all corners of the nation.

It's worth noting that this project was a costly and risky proposition. Building continuous rail lines required access to tens of thousands of miles of land. To support these endeavors, the federal government provided each company with ownership of public lands on either side of the track, as well as additional land grants and payment through load bonds. This governmental support enabled these two private corporations to accomplish their mission, helped stimulate the broader American economy, and marked the beginning of the nation's first "big business."

Which statement best describes the popularity of Uncle Tom’s Cabin?
Uncle Tom’s Cabin was most popular in the North.
Uncle Tom’s Cabin was most popular in the South.
Uncle Tom’s Cabin was popular across the United States.
Uncle Tom’s Cabin was not popular and few people read it.

Answers

I'd say the correct answer is A. Uncle Tom's Cabin was most popular in the North.
B is definitely not correct because the book is about anti-slavery, and there were many slave owners in the South and they hated the book with a burning passion; thus C is also incorrect because the South almost banned the book; D is incorrect as the book was hugely popular in the North, having become an instant bestseller (took the second place after the Bible).

the spread of railroads during the 19th century contributed to U. S. industrialization by:
a) giving factories easier access to natural resources from around the country

b) ensuring that American businesses would not need to use canals for shipping

c)allowing factories to be located in remote rural areas

d) reducing the amount of dangerous pollution affecting large American cities

Answers

Answer:

a) giving factories easier access to natural resources from around the country.

Explanation:

The spread of railroads during the 19th century greatly contributed to the industrialization of the country. Before railroads became widespread, businesses needed to operate locally, and this meant that their access to natural resources was very limited. However, as transportation became faster and more easily available, new sources became an option. Factories had an easier access to natural resources from around the country, making production cheaper and more efficient.

Final answer:

Railroads during the 19th century contributed to the industrialization of the U.S. by facilitating the transport of natural resources to factories and goods to markets, hence supporting the country's economic expansion. So, the correct option is a : giving factories easier access to natural resources from around the country.

Explanation:

The spread of railroads during the 19th century contributed to U.S. industrialization primarily by giving factories easier access to natural resources from around the country. This growth in the railroad industry led to a transportation infrastructure that fueled the growth of American commerce. With rail lines covering nearly every corner of the United States, they brought raw materials to industrial factories and finished goods to consumer markets, enabling the economic expansion and creation of a national market system. This was essential for a country with expansive territory and resources like the United States, as it allowed for the rapid transportation of goods across long distances, linking resource-rich areas with centers of production and consumption.
