LO 2.7 I understand cell size and shape affect the overall rate of nutrient intake and rate of waste elimination by determining LO 2.8 I understand data, regarding the types of molecules that an animal, plant, or bacterium will take up as necessary building blocks and excrete…

eukaryotic cells. More than 20 different versions of Endosymbiotic theories have been presented in literature to explain the origin of eukaryotes and their mitochondria (Martin, Garg and Zimorski, 2015, p.1678). A Prokaryotic cell contains structural components such as: Cell wall is made of peptidoglycan. Gram-positive bacteria contain a thick cell wall with many layers of peptidoglycan and gram-negative bacteria have only few layers of peptidoglycan. The cell membrane of a bacterial…

Pure-bred Sprague Dawley rats (brown laboratory rats) are to be used in this experiment. These rats are preferred due to known calmness and ease of handling. To reduce variability, rats of the same weight, age, and gender will be chosen. Thirty-seven ADHD rats and thirty-seven non-ADHD rats will be chosen. This provides a sample size large enough to produce statistically significant values. Because there is no physical biological marker for rats with ADHD, behavioral symptoms must be…

Cell Structures-DBQ Genetic engineering is the changing of genetics for different reasons. Some reasons might be changing the genes for the better, Some not so much. Genetic engineering is a good thing in some conditions. Don’t create a half turnip, half trout, half human. I do think that you should help to cure diseases through genetic engineering. That is important because you could eliminate a disease altogether concerning human disease. Pain is a very important feeling to have to live. Pain…

in three separate layers - the stratum corneum, the epidermis and the dermis [39]. The protective stratum corneum is the outer layer that we can see, the epidermis is the layer of skin underneath it, and the dermis is the lowermost layer [40]. The cells of the stratum corneum are basically dead, and they protect the body from the harsh outer environment [41]. The epidermis is mostly responsible for producing…

stable transfection allows the plasmid to remain in the cell genome, in contrast to transient transfection where expression is limited due to eventual degradation. The plasmid integrates into the genome of the transfected cell, and becomes part of the cell line, passing on during replication8. Different reagents and other physical tools involving electrochemical changes can be used for transfection, and efficiency depends on the specific cell type. This experiment uses the Lipofectamine…

Advancement in the area of science and technology has always created a buzz in our world. Our world runs on the belief that scientific discoveries or breakthrough will one by one rid of diseases and illnesses that is trying to harm human life, but it also runs on technology, from people’s need of energy/electricity for light to people’s addiction to smartphone, internet, and need of Wi-Fi. The advancement in both areas would have not been possible without the help of each other; the…

Duchenne muscular dystrophy (DMD) is a one type of muscular dystrophy. Muscular dystrophy is a group of genetic disorders, leading to progressive muscle degeneration. People suffering from most common muscular dystrophies ,Duchenne/Becker (DMD), Myotonic (MMD), and Limb-Girdle (LGMD), experience muscles degradation overtime, leading to overall muscle weakness and decreased mobility. Statistics show that the most prevalent forms of muscular dystrophy are rare. For example in 2007 in the…

Hypothesis: 1.) Animals with nocturnal sleep cycles will have greater similarity in the PER gene than the PER gene of diurnal animals. 2.) Differences in the sequences of PER genes can account for variance in the free running period (FRP) between varying organisms. 3.) Human PER gene homologs arose from prior duplication events throughout evolution. Motivation and Background: The biological clock is an endogenous mechanism that regulates the physiological activities of an organism. It was…

What is Genetics? Genetic Diseases A genetic disease involves an abnormality in genetic material. Otherwise, there could be mutations or changes in an organism’s DNA. A genetic disease can be inherited through a family. There are three types of disorders: Chromosomal Disorders, Single Gene Disorders, and Multifactorial Disorders. Chromosomal Disorders are caused by too many chromosomes, not enough chromosomes, or the chromosome structures are abnormal. Polymelia is considered as a…
