Different Stages Of Cell Division - 1139 Words

1) Cell division is typically explained through the progression of 4 distinct phases, G1, S, G2, and M, and can be tracked through CDK complex concentration ranges. CDKs are cyclin-dependent kinases, which regulate the cell cycle of eukaryotic cells; as suggested by the name, protein kinases are an enzyme that is dependent on cyclin for the regulation of cell division through the addition of phosphate groups. The different stages of the cell cycle correlate with different levels of cyclin and act as a threshold that once reached, triggers a phase transition. For example, for a cell to move out of G2 phase into M phase, Cyclin B interacts with the CDK1 complex, and causes phosphorylation to stimulate the phase shift; however, if the stage is not complete, the whole process slows down to accommodate the discrepancy in CDK complexes (Nelson Education, figure 9.17, page 191). This can be caused by several things, such as the presence of damaged or deformed DNA, or externally through con tact inhibition, where a delay in phase shift is caused by partial or incomplete contact of all cells. If there is only partial cell contact, contact inhibition will typically prevent progression past the G1 phase until there is complete cell contact, which can be reflected in variable levels of the CDK complex(Nelson Education, page 191). Overall, CDK regulates cell division through the combination of CDK and cyclin, the activation of protein via a phosphate group that triggers a phase change,Show MoreRelatedBiology Mitosis Lab1242 Words   |  5 PagesAP BIOLOGY- Mitosis and Meiosis Cell Division Lab Part 1-MITOSIS summary: In this experiment first the stages of an onion cell undergoing mitosis are going to be observed and every stage is going to be detected and drawn on paper.

Common Characteristics of Civilization free essay sample

Many people define civilization in different ways. Both archeologist Child and another historian thought for civilization to exist it had to include: the plow, wheeled cart and draft animals, sailing ships, the smelting of copper and bronze, a solar calendar, writing, standards of measurement, irrigation ditches, specialized craftsmen, urban centers and a surplus of food necessary to support non-agricultural workers who lived within the walls of the city. In addition, the historian thought that a civilization needed human organization, too, not Just human achievements. He leveled a civilization also needed money collected through taxes, a privileged ruling class, a centralized government and a national religious or priestly class. Then there was Chuckhole who believed there were three necessary factors for collocation: towns containing more than 5000 people, writing, and monumental ceremonial centers. Lastly, there Is anthropologist Adams who believed that collocation needed: class stratification based on the ownership and control of production, political and religious hierarchies complementing each other In the central administration of territorially organized states and lastly, a complex division f labor, with skilled workers, soldiers and officials existing alongside the great mass of peasant producers.

I do feel there are certain things you must have to be a civilization: the ability to communicate this is essential for organization and planning, a government hierarchy to keep law and order, an abundance of food to support a large community, and skilled workers to craft tools.Just like the text stated, civilization is a word easier to describe than it is to define. However, I do not feel that the word civilization accurately characterizes groups of people. This word encompasses many people and their cultures, so it would put two completely different groups of people (republicans and democrats) under the same definition. Even though these two groups of people may live together In a civilization and share common things, they have many differences.Common Characteristics of Civilization: By linearitys civilization: towns containing more than 5000 people, writing, and monumental ceremonial centers.

UDL Solution Plan

Universal Design for Learning (UDL) solution plan is a tool used by educators to reduce learning barriers. Today’s educators are supposed to provide their students with high standards of learning despite the fact that some of their students have learning difficulties such as Dyslexia, language barriers, emotional problems and physical disabilities. Through UDL, learner’s disparities can be addressed and their needs met. UDL takes advantage of digital learning resources, hence making the learning process more effective and efficient.Advertising We will write a custom essay sample on UDL Solution Plan specifically for you for only $16.05 $11/page Learn More For my class I have to use several teaching methods to ensure that my students meet their individual needs. A universal curriculum has been designed to achieve the leaning objectives through the appropriate ways of presentation, means of expression and methods of engagement. Therefore, all my teaching plans should be guided by these principles. Based on my experience with Nell, I am expected to use assistive technologies to help improve mobility, self-esteem, personal care and reading skills. To improve his mobility, a walker and braces are essential and mandatory. A walker will help him in exploring his environment by indicating the location of different rocks, how to extract them and their economical importance in the society (Kleinert, 2001). Through active participation, his mobility as well as his environmental awareness will considerably improve. Furthermore, it will not be easy for him to study either, so I have to offer him a wide variety of studying materials, such as textbooks and online resources that are beneficial to him. The study materials should precise and easy to use in obtaining information in order motivate readership. Moreover, he might find it hard reading printed textbooks due to his low comprehension skills. Visual aids will be necessary to hi ghlight key information like headings. In addition, the use of power point will serve the same purpose. An oral translator will be of significant assistance this would mean that difficulty in decoding text would be minimized. Words that appear too technical for him would be replaced by an oral translator with simple and understandable words. Nell has a low self-esteem, which affects him negatively. To enhance his oral reading I should provide him with the appropriate support. Providing him with the project a week before the class lesson will help him in familiarizing himself with the content and hence he will be more comfortable with his classmates.Advertising Looking for essay on education?

For Nell to improve his social skills, student’s participation will be vital, as this will ensure that students appreciate his participation. Nell’s inability to communicate in English presents difficulty in learning. Establishing a continuous feedback mechanism will be appropriate as this will ensure clarity and additional support. The provision of several resources will lead to access and evaluation of multiple examples. Samples of rocks will be of great importance as this will be used as practical examples during class work and students will be able to counter check their theoretical characteristics and the physical ones(Scherer 2004). In conclusion students with spina bifida rely heavily on assistive technology. This necessitates more research to be done to identify their response on several UDL methods and impacts of these methods on their daily life. I think that with more research and support students with disabilities will be able to live independently and participate fully in the community. To teachers like me, as sessments would be made more effective and efficient only by continuous research. References Kleinert, H. L., Kearns, J. F. (2001).
