Biology 1010 is a course that introduces students to the basic biological phenomena in all living organisms. It focuses on the different molecular levels of organization‚ heredity in evolution‚ genetics and reproduction. Through this course‚ I was able to master three essential concepts such as Mendel’s Law of Segregation‚ enzymes‚ and photosynthesis. Gregor Mendel was an Augustinian monk that argued that parental traits are passed on to their offspring discrete “heritable factors”. Heritable factors

the use of energy by the cell. During passive transport‚ substances move down their concentration gradient‚ hence no energy is required. Passive transports can happen through three different channels‚ namely 1. lipid bilayer 2. pore protein 3. carrier protein SIMPLE DIFFUSION What is diffusion? Diffusion is the movement of particles from a high density region to a low density region. No energy is needed and no membrane involves in diffusion. The Dynamic Equilibrium Diffusion

When the light hits the tube the leaf discs will produce oxygen gas and float

Introduction Most organisms produce adenosine triphosphate (ATP) as a source of energy for cellular work‚ using cellular respiration. Cellular respiration is a process that involves glycolysis -breaking down glucose into two molecules of 3- carbon pyruvate‚ the Krebs cycle - oxidizing organic fuel derived from pyruvate-‚ and the electron transport chain - moving electrons through a series of protein complexes to generate ATP (Reece‚ et.al‚ 2011). The process of cellular respiration occurs

Molecular Biology Lab Report Mapping DNA using Restriction Enzymes Ava II and Pvu II to cut Bacterial DNA Abstract The objective of this project is to map bacterial DNA‚ which is derived from E. coli‚ using restriction endonucleases with gel electrophoresis. The DNA fragments‚ after cutting has occurred‚ are separated using agarose gel electrophoresis. The DNA fragments are placed in the gel‚ and an electric current is run through the matrix of the gel-like agarose. Migration of the fragments

One of the main responsibilities of a medical lab is to determine the identity of pathogenic bacteria. It is important to determine the specific type of bacterium causing disease so the physician is able to correctly treat the patients. The structure of bacteria plays a crucial role of what antibiotics

the pistils. The ovule contained inside the ovary is fertilized and the ovule begins to harden and form into a seed to protect the embryo until it begins to grow into a new plant. The embryo grows inside the ovule and then develops into a fruit. 3. Many types of flowers produce fruits that are fragrant and sweet tasting. Describe how these characteristics of fruits may be important for dispersal. These types of fruits could be more appealing to animals that depend on plants for food. These animals
