EXPERIMENT ONE- BIOLOGY MODEL Answers TO DETERMINE THE EFFECT OF CHEMICALS AND TEMPERATURE ON MEMBRANE DESTRUCTION AND PERMEABILITY IN BEETROOT (Beta vulgaris) Introduction The cell membrane is made up primarily of phospholipids and proteins which contribute to its selectively permeable nature. The function and permeability of the cell membrane depends on its intact structure. When destroyed‚ the permeability of the cell membrane is disrupted causing cellular contents to leak out. The cell

to learn. The area of study that interest me the most is Biology; the study of living organisms. I’m passionate about it because I desire to know how living organisms function for I could eventually use that knowledge to improve the quality of life of people. Meanwhile that I’m still enrolled in BMCC‚ with the guidance of professor Adolfina Koroch‚ I have created a busy schedule for next semester. I will be an assistant professor for biology assisting in the labs and giving tutoring to the students

I am very good at Biology as it is the main subject required for this course and have a good understanding on a cellular level of organisms (plants and animals). I am a negotiator and prefer to work in teams‚ paying close attention to everyone’s opinion and making decisions accordingly. I have studied all three sciences at school level and because Biology was the subject I was very much interested in is what has compelled me to pursue a career in a Biology related field. At level 3 I am

my first glimpse at molecular biology then. But that brief introduction to molecular biology was enough to compel me to the idea that I want to spend my whole life working and conducting research on it. That passion and zeal brought me to where right now I am. I have successfully completed my masters from the Department of Genetic Engineering and Biotechnology‚ University of Dhaka. I want to note that very few universities offer courses related to molecular biology here in Bangladesh but University

or cell doctrine‚ states that all organisms are composed of similar units of organization‚ called cells. The concept was formally articulated in 1839 by Schleiden & Schwann and has remained as the foundation of modern biology. The idea predates other great paradigms of biology including Darwin’s theory of evolution (1859)‚ Mendel’s laws of inheritance (1865)‚ and the establishment of comparative biochemistry (1940).

Biology is the science of life. That includes the structure‚ function‚ growth and evolution of a living organism‚ for example humans. There are many levels of study in biology that include botany‚ zoology‚ and the study of cells in a molecular level. Psychology is the science that studies mental processes and behavior. Like Biology‚ there are many levels of study in psychology that may include animal psychology‚ child psychology‚ ect. But what we may not take into consideration is that

“life.” How do we study life? Life is studied in biology‚ biology is the study of life because in biology we analyze specimens‚ like micro organisms and bigger organisms like the human body through microscopes. We also further analyze the 6 characteristics of life in biology. By experimentation‚ and observing various things like cells and animals‚ and trying to establish fact by finding a pattern.. Why do we study about life in biology? Well we study
