What bone fragments were used to convict luetgert?
expeople1 [14]

Adolph Louis Luetgert, born on December 27, 1845, was originally named Adolph Ludwig Lütgert. He was born in a town called Gütersloh, located in the province of Westphalia, which is now a part of Germany.[4]

His parents, Christian Heinrich Lütgert and Margreta Sophia Severin, had sixteen children; twelve other sons and two daughters. Adolph was the forth born in the family, and he also had a twin named Heinrich Friedrich "Fritz" Luetgert, who died before Adolph around 1894 or 1895. While Adolph was growing up, his father dealt with animal hides and tallow wool as well a dabbling into real estate.

Adolph's schooling lasted from about the age of seven until the age of fourteen and after those seven years of schooling, Adolph became an apprentice for Ferdinand Knabel who taught him about the tanning business. During the time of the apprenticeship, Adolph continued to live in Westphalia however as an apprentice he lived with his boss instead of his family. After working for Knabel for two and a half years, Luetgert began to travel around Germany, working wherever he could. At the age of nineteen, Luetgert traveled to London, England where he stayed for about six months but left because he was unable to find a job other than scrubbing restaurant floors.[5]

Adolph Luetgert came to New York in around 1865 or 1866 when he was about twenty years old. Like many others, he had heard that thousands of his countrymen were going to America with very little money. With about thirty dollars to his name, Luetgert boarded a ship bound for the United States.

Luetgert arrived in New York and after a short time there he went to Quincy, Illinois to meet up with some friends of his brother who were living there. He stayed in Quincy for about four months before moving to Chicago in search of a job at a tannery. He found a job at Union Hide and Leather Company. He did not have a steady job or constant pay at the tannery, so he began to also take on random jobs such as moving houses. From 1867 to 1868, Luetgert got a job at another tannery called Engle, Crossley & Co. He then worked at another tannery called Craig, Clark & Company, but later returned to work at the Engle Brother's Tannery until 1872.

Luetgert then started his own business with the four thousand dollars he had saved. Initially, he went into the liquor business before starting his sausage company in 1879.

He married his first wife, Caroline Roepke, sometime between 1870 and 1872. She died on November 17, 1877. He married his second wife Louise Bicknese, two months after Caroline's death, on January 18, 1878. Luetgert had six children—two with Caroline and four with Louise. Only three of his children survived past the age of 2.[5]

According to the cell theory, which describes cells?
zysi [14]

Answer: D. All living cells come from other living cells.

Explanation:

A is incorrect because organisms like bacteria and amoebas are unicellular, or have 1 cell.

B is incorrect because cells are specialized: nerve cells and muscle cells do not share the same function.

C is incorrect because inanimate objects are not alive and do not have cells.

D is correct because cells reproduce by mitosis, creating copies of themselves.

Match the steps in the cell cycle in the correct order
Tcecarenko [31]

Answer:

1. Chromosomes line up - metaphase

2. Cell growth - G1

3. Final preparations for division - G2

4. Chromosomes get pulled apart - anaphase

5. DNA replication - S

6. Chromosomes condense - prophase

7. Chromosomes uncoil and nucleus reforms - telophase

8. The cytoplasm and organelles divide, and now there are two identical cells - cytokinesis

Explanation:

There are four primary phases, or stages, in the cell cycle, which is a systematic process. Each stage has a goal that has to be achieved before moving on to the next. G1, S, G2, and mitosis are the stages.
There is growth during the G1 phase. A lot of protein is produced and water is pumped in, increasing the volume of the cell. The DNA is also examined at this time to see whether there has been any damage. The G1 phase precedes the S phase, therefore before going into S phase, the cell must make sure it has enough energy reserves.

The cell duplicates its DNA during the synthesis phase, also known as the S phase. DNA content doubles due to the duplication of all chromosomes. The compact state of DNA is created by proteins, which do not exist in and of themselves. Therefore, in order to ensure that the new DNA is properly packed when DNA is replicated, new packaging proteins must be produced. Histones are the proteins that house DNA. The production of new DNA is closely linked to the production of new histones.

A cell multiplies its organelles during the G2 phase. Right before the cells divide into two distinct cells during mitosis, the G2 phase occurs. There must be distinct functioning organelles in each daughter cell. Organelles like the golgi and endoplasmic reticulum are linked networks of sizable membrane pouches that may change size. Other organelles, including mitochondria and chloroplasts, are separate structures that must separate similarly to how cells do.

The process of physically dividing a cell into two daughter cells is called mitosis. Prophase, metaphase, anaphase, and telophase are its four basic stages. The nuclear membrane deteriorates as the chromosomes thicken during prophase. The center of the cell's chromosomes align during metaphase. One chromosome splits in half during anaphase, sending one half to either side. The telophase is characterized by the pinching together of the cell's centre to form two separate cells.
