Homework Help: grammar help

Posted by zee on Saturday, March 17, 2012 at 4:10pm.


Please help me fix grammatical and any other mistakes in my writing.

So the story begin when a small aerobic prokaryote came in a large prokaryote the large prokaryote ingests it and it turns to a mitochondrion , then a small photosynthetic prokaryote comes the large prokaryote ingests it and it turned to a chloroplast. The life use to consist of 3 large domains archaea, bacteria, and eukaryotes. The evolution of eukaryotic cells happened when an organism lived inside the other and occupies permanently, and evolves over time into what I call a one nation.

The first thing I would look for to tell whether a cell is a prokaryotic or a eukaryotic is the cell size. Eukaryotes are larger and more complexing than prokaryotic cells. The second thing I would look for is the nucleus if the cell had a nucleus it is a eukaryote. And Prokaryotes do not have a nucleus. Eukaryotic cells have organelles and prokaryotes don’t.
Eukaryotic DNA is bounded between a membrane witch creates a nucleus. DNA in prokaryotes isnt bounded to a nucleus. So in eukaryotes the DNA is housed in a nucleus and prokaryotes lack the membrane-bound nucleus and there DNA is located in a nucleoid region.

Ribosomes are tiny organelles that the cell needs to make proteins. Proteins and RNA structure the ribosomes and two subunits consists it.
Ribosomes have ribosomal RNA (rRNA). Ribosomal RNA is produced from the nucleolus. DNA gets transcribed into MRNA. MRNA leaves the nucleolus and gets translated into proteins at ribosomes. Ribosomes make proteins from amino acids.


E. coli bacterium and salmonella are examples of prokaryotic cells.
E. coli are single celled microorganisms. E. coli isn't always bad for our body. They usually live in our intestines to help us digest food. There are bad kinds of E. coli that can poison us. The poisons kind of E. coli can be found in raw meat, and fruit juice that isn’t pasteurized. Salmonella are harmful bacteria's that are passed from the feces of people or animals to other living things. They cause illness and affect the intestines in our body. It can also come from raw meat and eating raw eggs.
To avoid the harm of these bacteria's we should wash our hand when we get out the bathroom. We should avoid eating raw food and eggs.
