Cell biology

All cells are derived from pre-existing cells - through the process of meiosis and mitosis 4. In a multicellular organism, the activity of the entire organism depends on the total activity of its independent cells 3 Significance of technological advances to developments in the cell theory Assess the impact of technology including the development of the microscope on the development of the cell theory The development of cell theory has been heavily impacted by the improvement of technology. The…

primitively social behavior of Euglossa cordata (Hymenoptera, Apidae, Euglossini): a view from the perspective of kin selection theory and models of reproductive skew. The evolution of social behavior is perhaps one of the most controversial topics of biology, since the emergence of such behavior implies the evolution of altruistic traits that reduce the chance of reproduction (fitness) of individuals, through Natural Selection ( Freeman & Herron, 2009). Currently, there are models that link…

Cells Research Assignment I. Define the following terms CELL NOUN The (usually) microscopic structure, known as a cell. Is the functional and biological unit of all organisms (life forms). INFERENCE NOUN Is a conclusion, idea and/or opinion that is reached on evidence, reasoning and the information that you have. It is simply, an educated guess. Synonyms implication, interpretation, deduction, reasoning, speculation, presumption, assumption. OBSERVATION NOUN 1. An act of viewing,…

able to understand the biology behind Tay-Sachs but plausible theories have been uncovered as to why Tay-Sachs has a tendency to occur more frequently only in 3 particular populations.…

not surrounded by a membrane but are located in an area of the cell called the centrosome. The centriole has its appearance and structure the way it is because its arrangements must be a circular and the triplet fibers that it’s made out of will eventually create a shape that is similar to a barrel when it it is arranged. One of their main function is to contribute/help with processes that involve cellular activities. One example of cell division where centriole plays a role in mitosis where…

Introduction Genetics is the process of inheritance of traits from parents to offspring, including the molecular structure and function of genes. Epigenetics is a new discipline in which the word “epi” means above that is epigenetics means above genetics or the control above genes. Aaron et al., defined “Epigenetics as a bridge between genotype and phenotype- a phenomenon that changes the final outcome of a locus or chromosome without changing the underlying DNA sequence” [1]. Epigenetic gene…

In the last two years doing research concerning cancer biology, I realized that cancer is such a sophisticated disease. It’s almost like a great villain in superhero movies, with each metastatic cell taking out whatever comes in its way while stealthily stealing nutrition and blood supply to feed itself. Selfishly maximizing its own chance at survival, cancer is complicated, invasive, aggressive and intriguing. Going forward into graduate schools, I hope my research will continue in the field…

earliest living thing with a neck, meaning that it can turn its head and look around independently of its body. It also has a limb structure that is just like humans, horses, and everything else. This is a pure example of common descent. In evolutionary biology, a…

An analysis of over 100 mouse cell types found that only 50% of the DNA responsible for regulating genes in mice could be matched with human DNA. How could this be safe? Tests that may pass as safe on a mouse may not have the same effects as a human. II. Many will argue that if we…

are made up by the building blocks of life named “cells”. They are the foundation of life and contain microscopic components called organelles which carry out complex tasks to provide the “basic structural, functional, and biological unit of all known living organisms” (Wikipedia, Cell(Biology), viewed 19th March 2016, Cells can be classified into two major groups- Prokaryotic and Eukaryotic cells. Prokaryotes are organisms that do not contain a cell nucleus and have no membrane bound…
