light microscope when you want to see the cell in the act of moving or dividing. 2. Prokaryotic cells don’t have organelles like eukaryotic cells do. Eukaryotic cells contain its DNA within its nucleus‚ while prokaryotic cells keep it within the nucleoid. Prokaryotic cells are also more minute than the eukaryotic cells. Also although they both contain ribosomes‚ they are composed differently. 3. The central vacuole (takes in water and chemicals)‚ cell wall (allows the plant to be strong enough

Cell City Cell City A cell is like a city. They both have parts that play different roles. A cell is microscopic that has organelles‚ and a city has different services. Keeping them both running smoothly and orderly. As a result they both survive and grow. There’re a lot of different organelles in a cell that are similar to a city for example the cell membrane borders and protects the cell it’s role is letting certain things in and out of the cell in the same way a border in a city does.

CONCLUSION Leisure and recreational activities engaged in by the majority of adults‚ teenagers and children were generally passive or non-active‚ and tended to occur in the home. There is‚ however‚ a desire for more variety‚ particularly for activities outside the home. Shortage of time and money limited leisure opportunities for both adults and teenagers‚ along with the shortage of entertainment venues and transport difficulties reported by teenagers. Choices about leisure and recreation‚ the type

21 October 2013 Cell phones Should we allow students to use their cell phones in school? Would it be benifical for students? Students should have the abilty to use their cell phones in school because you will never know what will happen to you or your child. There can be any type of an emergency such as earthquakes‚ a crime scene‚ or a fire. Students should be able to use cell phones in school because how about if someone was going to get hurt and didnt have a way to get help or find help

address this question: “Propose a possible explanation on why the light caused depolarization of the off-center ganglion cell?” we first have to describe the structure of the center -surround in the receptive fields of retinal. In the receptive field‚ there are cone photoreceptors that communicate with On and Off center bipolar cell and finally On and Off center ganglion cells that carry the action potential to the cortex. When light comes to the retina (eyes) it causes closing of channels in the

Conclusion We therefore conclude that our program will solve the problems regarding to the UAM (Uniform Accelerated Motion). This will got to be a help in studying Physics because it’s an easy way to solve problems regarding the topic that we’ve said earlier. This program didn’t aim to teach the students to be lazy and not to study at all but our program aims to help the students to simply solve the problems given. Recommendations More knowledge should be given to us to make

develop a manufacturing cell? Support your answer with examples. Cellular manufacturing is a manufacturing process that produces families of parts within a single line or cell of machines operated by machinists who work only within the line or cell. A cell is a small scale‚ clearly-stated production unit within a larger factory. This unit has full responsibility for producing a family of like parts or a product. All necessary machines and manpower are enclosed within this cell‚ thus giving it a level

him or her having Sickle Cell Disease. What this is is it’s a disease that is genetically inherited and it involves the red blood cells. Mutations in the HBB gene cause this disease. This disease is inherited in an autosomal recessive pattern‚ which means both copies of the gene in each cell will have mutations. The parents of offspring with an autosomal recessive gene each carry one copy of the mutated gene. The blood cells form an abnormal crescent shape (normal cells are in a disk form). The
