Introduction: The common fruit fly‚ Drosophila melanogaster‚ is mainly used for genetic studies. Fruit flies are easily cultured and can reproduce in as little as two weeks at the proper temperature. (Book) The purpose of this experiment was to study the transfer of genes between homologous chromosomes by crossing over. During our experiment we studied three X-chromosome genes: white (w)‚ miniature (m)‚ and forked (f). To begin this experiment we started with four types of flies; sepia‚ dumpy‚ wild

BIOLOGY 2020 LAB LAB 4 – Sensory Systems I. Vision 1. Know the types of photoreceptors in the retina. (Remember there are 3 different types of cones) 3 cones i. Blue- short ii. Green- Medium iii. Yellow-Red- Long 2. Why would near point accommodation change as you get older? (Think about what happens to the lens and the muscles of the eye with age) As you get older‚ the lens becomes hardened. The elasticity of the lens decreases dramatically with age‚ resulting in difficulty

Education 1 The Importance of an Education Ashley Todd ENG 101-D20 4/04/2013 Education 2 The Importance of an Education When Alfie Kohn wrote his paper What Does It Mean to Be Well-Educated? he tried to focus on everyone’s point of view. He wrote about how there are many different types of people who are able to hold a job with maybe just one degree against the other who may be unemployed but have multiple degrees. Why would having more initials at the end of your name guarantee your success

I’ll just print one off for you.” A brief glance at how future medicine for the next generation could be. With the invention of the ingenious Bio printer‚ this could be done! It is certainly creating a buzz in science and medical institutions globally. 3D printing is fast becoming a massive part of manufacturing and fabrication all over the world. Scientists

agar plate‚ and then observed to see whether or not bacteria colonies grew and whether or not they glowed. Our data fully supported our hypothesis. We can thus conclude that bacteria can take in foreign DNA through the process of transformation and that this foreign DNA can fundamentally change the bacteria (ex: making it glow). Future research can involve inserting other pieces of DNA into bacteria from different organisms‚ making the bacteria take on various phenotypic characteristics. Background

Your first lab link can be found at What Makes a Good Parent? A written transcript is also available for this lab. What makes a good parent according to Dr. Tanya Byron? 1. A good parent is one that doesnt worry to much. Parenting comes from the heart. What are some of the common problems that children might have? 2. With little ones is the behavior problems‚ as well as sleep problems‚ and toliting problems or eating. Why is play important in the parent-child relationship? 3. It helps give attention

FRUITS‚ SEEDS AND THE FUTURE JEANETTE JOHNSON A fruit results from the maturation of one or more flowers. The ovule producing part of the flower forms all or part of the fruit. Inside the ovary/ovaries are one or more small eggs‚ where the embryo sac contains the egg cell. When the female embryo sac joins with two male sperm these ovules become seeds. (Biology Online‚ 2005) Each fruit is made of certain acids‚ vitamins‚ fructose
