Name: Desire Salazar Date: 12/15/17 Period: Pre-AP Biology 5th Title: Population Genetics and Evolution Problem: How does the Hardy-Weinberg law provide evidence of evolution? Background Information: The lab will determine how the Hardy-Weinberg law provides evidence of evolution in a population. A population is “a group of organisms of one species that interbreed and live in the same place at the same time” (Biology Online). In each population, are three key elements: size, density, and…

allowed scientists to develop a better understanding on the way diseases originate in humans. Molecular biology in particular has allowed scientists to discover the way in which domains, found in proteins impact a genome. Domains are autonomous folding units that carry out specific functions and mechanisms in a certain protein. These functions consist of being responsible for interactions in the cell, which ultimately determines the role of the protein. Domains found in proteins can develop…

Growing up studying Biology I have increasingly become aware of the perplexity and beauty in which the subject holds. What truly intrigues me is the complexity of the human body, how one gene mutation can result in intriguing occurrences of unique diseases that shape people’s everyday life. With our technological advances we have the ability to discover and learn the reasons behind these cases that consequently bring about world-changing breakthroughs not only in medicine but our basic concept…

As dpp diffuses through the neighboring cells, it activates either the type I receptor, Thickveins (TKV) or saxophone (sax), or both. TKV must be activated for any response to dpp and sax is only activated at high levels of dpp. TKV is responsible for the growth of the wings. If the signal is overly amplified it can result in the overgrowth of the longitudinal wing vein. If dpp is not signaling to grow more, then it is captured and destroyed by the cell which contributes to this gradient of…

DNA in Forensic Science Every organism contains cells within which an organic polymer called Deoxyribonucleic acid (DNA) is found. This particular polymer is composed of the phosphate backbone part, deoxyribose sugar part and also the nitrogenous base part. According to Butler, (2010), the phosphate backbone and deoxyribose sugar components are constant in all persons and, therefore, biologists today utilize the nitrogenous base component since it helps in distinguishing different individuals.…

“These modern methods include sophisticated tests using human cells and tissues, advanced computer-modeling techniques, and studies with human volunteers” (“Alternatives to Animal Testing”). Scientists began doing these tests because they were faster and they costed less money. The first kind of test is a cell culture test which is where scientists are able to grow human organs. “Human cells have been used to create innovative little devices called ‘organs-on-chips’. These can…

currently sourcing some of his material to read. This initiative and willingness to learn makes me well-equipped for the demanding nature of the course and will keep me motivated throughout. I completed the Biology Olympiad to demonstrate my improved approach to unfamiliar problems; I found the cell biology and biochemistry sections most enjoyable and ultimately I achieved a Highly Commended which I am extremely proud of. This year, I aim to spread my enthusiasm for biochemistry by aiding Year…

maths has helped refine my problem solving and data handling skills. Psychology has broadened my research and debating skills as well as my ability to apply studies to theories which is crucial to the field of biomedical science. Learning about cell biology in BTEC Applied Science was stimulating and encouraged my desire to undertake this course. During the week, I volunteer at a local charity shop where my work involves interacting with the general public…

Being a curious person with some little knowledge of biology I have always been interested in the human body and always wanted to know how the complex mechanism of the human body works to enable an individual function properly from simple cells combining together to form tissues, organs and then an entire human body. Further my curiosity lead me to interlude upon the term Biomedical Sciences, and on searching more I was able to understand its benefits as a career as it is certainly a constantly…

Up to the elementary school, my cumulative treasure of science was pertaining mostly theories but hands-on practical started during my Honor Biology labs. The smell of formaldehyde didn't hold me back, to dissect a preserved frog to learn about frog's internal organs. As the human and frog have similarity in their organs' layout. I nailed arms and legs wide open and my scalpel made an incision along the midline of a frog's body from pectoral gland to the pelvis. The entire cavity, filled with…
