Organelle

“Oh my Perry! Have you ever realized how the cell wall is just like the brick walls and the fences in the zoo? The cell wall protects and supports the cell, as the brick walls and the fences, they keep the animals from running away and people that aren't suppose to be there out.” “You know what Phineas? I think your right!! Tell me more.” 2. “Perry, what do you think the cell membrane reminds you of?” Phineas asked Perry. “The cell membrane has the same job as the ticket booth…

The nucleolus which is also known as the brain of a cell, is the most significant part in the nucleus. It takes up about 25 percent of the nucleus and it is not surrounded by a membrane. Through a microscope, the nucleolus is a big dot in the middle of it. It can be found in an animal, plant, diploid, and eukaryotic cell. It was found in the eighteenth century but its function wasn’t discovered until the 1960s. The nucleolus lives in the nuclear matrix. Sadly, the nucleolus is one of the…

The skin is largest organ in the human body, it covers every square inch of our bodies, for its function is to protect us from outside pathogens, but sometimes these pathogens can hurt our skin. Vitiligo is a skin disease that affects all people of all skin types, there is no specific gender or race that gets affected. Vitiligo is actually a common disease where it affects 1-2% of the world population. Vitiligo is a skin disease that results in the loss of skin color in blotches on the body.…

My goal is to eventually become a Veterinarian. I believe that I can complete this goal by majoring in Biology at the University of Illinois at Springfield. Biology and Chemistry have always been interesting to me. Whether it be learning about organelles in biology class or titrations in chemistry class, I always wanted to know more. Science, in general, has always been an interest of mine. It was not until I adopted my current dog that I really knew how I could apply those interests. Animals,…

An isotope is an atom containing different numbers of neutrons, differing in atomic mass. Basically an atom with a different atomic mass. What’s special about radioactive isotopes is that a radioactive isotope has a nucleus that decays spontaneously giving off particles and energy. 6. Radioactive tracers are used in science to label certain chemical substances, so metabolic processes can be followed and substances can be located in an organism. Radioactive tracers are important diagnostic…

Siqi Li May 2015 What topics will students address during the beginning of the school year in Buffalo? During the beginning of the school year in Buffalo, students will study two parts of Living Environment in 7 weeks. The main topic is about the introduction to the course includes the cell which is the foundation of the study of all living things. The key idea 1 in curriculum, living things are both similar and different from each other from nonliving things. The enduring understanding is…

Mitochondria, LHON The Organelle The most well known function of the mitochondria is to produce energy for the cell. It does this by regulating cell metabolism and respiration. Mitochondria carry out multiple other functions that are extremely important (such as various forms of signaling) The mitochondria also contains DNA which can have a direct effect on some functions of the human body if there is a mutation. ( Mitochondrion.(2016, October 9)) Word count 63 (not including headings or…

Respiration and Photosynthesis Respiration and photosynthesis are reactions that take place in the environment which complement each other, in the other case can be seen as a same reaction but happening in reverse of each other (Tang, 2005). In photosynthesis the ingredients/ requirement for it to place is water and carbon dioxide as they release oxygen and glucose as the products. Respiration to take place requires glucose and oxygen to yield carbon dioxide and water. Since the product of…

basis is carried by a red protein known as hemoglobin. It is able to bind to oxygen thanks to the heme group that it has, which has a iron molecule in the center with a +2 charge. Hemoglobin is a great oxygen transporter in the sense that it has no organelles, particularly mitochondria. So that it would not be able to utilize the oxygen molecules, that would be needed for the various tissues in our body. When hemoglobin binds to the oxygen molecules it is considered to be in a relaxed state,…

facultative anaerobe: an aerobe that does not require oxygen for its metabolism and is capable of growth in the absence of it (Cowan & Talaro, 2009, p. 185). S. pyogenes is a prokaryote because it is an organism that has no nuclear membrane, no organelles in the cytoplasm except ribosomes, and has its genetic material in the form of single continuous strands forming coils or loops (“Classification,” n.d.). S. pyogenes is a gram-positive bacteria cocci in chains and it causes many diseases in…
