a.1 Eukaryotic Cell vs Prokaryotic Cell All cells can be classfied into prokaryotes and eukaryotes. Prokaryotes were the only form of life on Earth for millions of years until more complicated eukaryotic cells came into being through the process of evolution. Comparison chart All attributes Differences Similarities | Eukaryotic Cell | Prokaryotic Cell | Nucleus: | Present | Absent | Number of chromosomes: | More than one | One--but not true chromosome: Plasmids | Cell Type: | Multicellular

The micoscope is designed to view the slide at different spots‚ so not all drawings will look like this one. Images were snipped from the virtual microscope’s flash animation.

Laboratory 3: Molarity Of Saline Solution Data: Please write your observations about the appearance of the solution. 1. Normal Saline- The solution appeared clear at the start with slight particles showing‚ once adding the salt it still appeared clear. 2. Nasal Irrigation Saline- Solution appeared cloudy once adding the salt and baking soda‚ then it turned semi-clear about 30 secs later; it was more concentrated than the normal saline. Results: 1. Determine the molar mass of NaCl. Show the workup

armed with cells that may function in defense and capture prey. The cells found within the tentacles are structurally and functionally unique to each phylum‚ such as the cindocytes in Cnidarians and colloblasts in Ctenophores. Cnidarians capture prey with special stinging cells called cindocytes. These cells are found throughout the epidermis but are particularly abundant in the tentacles. Cnidocytes contain a cilium or modified cilium structure with a kinetosome at its base. This structure is known

If cultural syncretism had taken root during early encounters in China or India‚ how might they be different today? My Part: #2 What cultural factors caused the differences
