Genetic Traits Exercise: Introduction: The pioneer of modern day genetics was an Austrian Monk named Gregor Mendel‚ who established the basic laws of heredity from his studies with pea plants in the late 1800s. Mendel’s fundamental genetic principles may be applied to a variety of traits from many different organisms. Each genetic trait‚ such as flower color‚ is regulated by a pair of genes called alleles. These alleles are found at particular places on the chromosomes called loci. During meiosis

Study Questions: Chapter 28 1.) Archaea and Bacteria are the oldest‚ structurally simplest and most abundant forms of life. 2.) Name and describe seven ways in which prokaryotes differ substantially from eukaryotes? Unicellularity- fundamentally single-celled Cell Size- can vary (large range changes with species) Nucleoid- lack a membrane-bound nucleus but rather a nucleoid region Cell Division/Genetic Recombination- binary fission (does not use spindle) and do not have a sexual cycle Internal

Chondrichthyes were my motivation to get involved and stick with Marine Biology no matter the challenges. Growing up I found comfort in sharks. Due to media and lack of understanding sharks were viewed only as malevolent killing machines. I thought this false‚ constraining label was unjust and unwarranted. Just as sharks had a constraining label I was stereotyped to be at best average when it came to academics. I had a minor learning disability that made reading and writing a major obstacle. After

Circulatory systems Closed circulatory systems: • Blood leaves heart under pressure to arteries then arterioles then capillaries. • Capillaries come in large numbers. They exchange substances between the blood and cells. • After passing through capillaries‚ blood goes back to the heart via veins. • Valves in the veins ensure that blood only flows in one direction. Single circulatory system: • Heart pumps deoxygenated blood. • Gaseous exchange (diffusion of CO2 from blood to H2O and diffusion

Introduction Our bodies produce waste‚ as does most of what we consume‚ the excretory system is responsible for removing this waste. It is essential that is waste is removed‚ or excreted‚ in order for the body to remain healthy. The human excretory system includes the liver‚ the kidneys‚ the large intestine‚ and the skin. Part 1: What Does the Excretory System Do? The excretory system is one of the most important systems in our bodies‚ as it excretes all the waste that would otherwise build up inside
