1.0. Introduction Head and Neck cancer is increasingly becoming a very serious public health issue in the world, correlated with high incidence and mortality rates mainly in developing countries(Jeffries and Foulkes 2001). Deformities caused by the malignancy such as facial and neck injuries profoundly affect …

I believe that our observations are repressentative of cell division taking place in the oinon root tip. Firstly, this is because our numbers of the number of cells in each phase of mitosis are similar to the rest of the groups, so we can assume …

First of all, plant and animal cells are eukaryotic cells. They have complex structures but they both have major differences, as well some similarities. Plant cell are usually larger than animal cell. Both types of cells have many organelles. The plant cell has a few …

Abstract Aim This review describes recent investigations in to the impact of atherosclerosis on the vessel using four inflammatory stages eventually leading to cardiovascular complication. Research in to atherosclerosis has intensified globally as it has become one of the main reasons for increased mortality among …

Introduction Step 1: The scientific concept of this lab was to see how osmosis transferred the substance through the cells to reach equilibrium. Step 2: My hypothesis was that the bag with 60% sucrose then it would be heavier than the bag with tap water …

Nanotechnology is a rapidly growing field of science, which is particularly interesting for researchers since the early 90s of the last century has become a vital part of the modern technology. Nanomaterials are increasingly becoming a part of our regular lives (Hill and Julang, 2017). …

The notion of “survival of the fittest” of Charles Darwin denotes competition in the available life resources among living organisms. Biologists typically classify competition as exploitative or scramble competition and interference or defense competition (Reebs, 2008). In exploitative competition, the species explore every nook in …

Using a human cell of your choice, describe how organelles work together to make and secrete a protein (LO1. AC 1. 1) An epithelial cell in the thyroid gland, called a thyrocyte forms spherical follicles that produce a protein called thyroglobulin. This is a globular …

After researching, I predicted that I would see different numbers of cells (which are the bubbles or the circles in all the different stages). I got some pictures from a website and I knew what to do, and how to tell how many cells are …

The problem, however, is that these chemicals are expensive and pose harm to the environment. This study aims to develop an environment friendly, safe, and effective yet cheap mosquito repellent by using weeping pillow leaves and pine cones. The activity is not success but it …

Motivation: Recent technological promotions in the field of genomics have resulted in Following Generation DNA Sequencing Technologies. These engineerings have created ballyhoo among scientists since they enable inexpensive and faster sequencing of the DNA as compared to traditional methods. Data Analysis, Genome sequencing and alliances …
