Molodets [167]3 years ago
5 0
<span>The endoplasmic reticulum (ER) is an organelle in eukaryotic cells. The name reticulum comes from latin word reticulum meaning network. Thus, ER forms a network of membrane-enclosed sacs and those membranes are actually continuous with the outer nuclear membrane. There are two types of ER - rough and smooth. Rough ER (or granular ER) has ribosomes bound to the surface of its membrane. Since ribosomes are involved in protein synthesis, rough ER, rough ER plays an important role in the assembly of proteins.</span>

European Jewish Immigration
Licemer1 [7]

Shortened version (if needed):

Many European Jews immigrated to the United States throughout the 19th century for better life and more opportunity. They soon found life in the American economy, and their culture rose to prominence in the U.S. through their religiosity, their work, and their social customs. However, many Jewish immigrants faced difficulty throughout the 20th century during the Holocaust and immigration restrictions. Despite this, many Jewish communities in the U.S. continue to remain prominent to this day within states along the East Coast.

Answer:

Affected by economic hardship, persecution from European governments, and many other social upheavals that occurred throughout the 19th century, many European Jews immigrated to the United States for better life and more opportunity. Many of these immigrants settled in American cities such as New York City, Philadelphia, Baltimore, and dozens more cities across the United States, primarily along the East Coast.

Many of these Jewish immigrants found work in the garment industry and started their own businesses. Though many Jewish immigrants came to the United States with little money, they quickly found life within the American economy mostly as workers, peddlers, and unskilled laborers. Their culture rose to prominence in the United States throughout the 19th and 20th centuries through their religiosity, their social network, their work, and their social customs.

However, by the 1920s, anti-immigration sentiment was growing, and a law was passed by the U.S. government known as the <em>Immigration Act of 1924</em>, which severely restricted immigration from many European countries, and as a result, it disrupted Jewish immigration from Europe. Although the law was repealed in 1965, the rate of Jewish immigration in the United States never topped rates before the 1920s ever again. Many Jewish immigrants opposed these immigration restrictions, especially as World War II started, and what became known as the Holocaust paved way for the persecution and death of many Jewish families in Europe. Many Jews in Europe continued to find ways to enter the United States during and after World War II, and to this day, many Jewish communities in the United States remain prominent in many states along the East Coast, especially in New York.

Some Eukaryotic cells have internal structures that are able to use photosynthesis to convert light energy into chemical energy
grigory [225]

Answer:

The correct answer is the letter b. The endosymbiotic event that brought chloroplasts into Eukaryotic cells actually happened after Eukaryotic lineages diverged so many lineages never actually possessed chloroplasts

Explanation:

The plastid is an organelle linked to membarna found in the cells of eukaryotic organisms, which contains pigments used in photosynthesis. Some eukaryotic organisms over time have inherited the ability to photosynthesize from cyanobacteria by secondary endosymbiosis or ingestion, and are able to capture and sequester photosynthetic cells and chloroplasts, this process is known as kleptoplasty.

Does the genetic message get altered when the information is conveyed intracellularly under normal conditions? Support your answ
IRINA_888 [86]

Genetic transmission is the mechanism that drive evolution.Asexually reproducing organisms reproducing organisms reproduce using mitosis, while the sexually reproducing organisms reproduce using meiosis.

Both these mechanisms are involved in duplication of DNA which then get passed to offspring and RNA is key component in the duplication of DNA. The genetic information heritable biological information coded in the nucleotide sequence of DNA or RNA.

Genetic material is includes genes and DNA which control the development , maintenance and reproduction of organisms. These messages is passed from generation to generation through inherited units of chemical information. It consist of only two transcription and translation they known as gene expression , during this process of transcription store in gene DNA is passed to similar molecule called RNA in nucleus.
