of water but also contains digestive enzymes‚ salts‚ organelles and other organic molecules. The prokaryotic cell also has a cell or plasma membrane which controls the movement of substances in and out of the cell. The pili are short‚ hair-like structures which attach the cell to other bacterial cells. Finally‚ the bacterial flagellum is a long ‘tail’ which helps the cell move.2 Prokaryotic cells can be harmful as they are bacterial cells and therefore can cause disease. Some of these bacteria

Associate Program Material Prokaryotic and Eukaryotic Cells Worksheet Provide a list describing at least three differences between prokaryotic and eukaryotic cells: 1. While Prokaryotes contain just one copy of each gene‚ eukaryotic cells have two. For such reason‚ prokaryotes are known as haploid and eukaryotic as diploid. 2. While Prokaryotes see some nonessential genes being encoded into extra-chromosomal plasmids‚ such activity is typically absent in Eukaryotic cells. 3. The own way

Chapter 2 Brain and Behavior The cerebral cortex outer layer of the cerebrum has the two largest hemispheres that covers the upper part of the brain which are divided into smaller portion called lobes. Corticalization is an increase in size of the wrinkling of the cortex and without this we would not be any smarter than any other animal. Cerebral hemispheres are divided into right and left halves of the cortex connected by thick band axon fibers called corpus. Hemispheric specialization‚ testing
