how living organisms look or work. They also control the manufacture of proteins in a cell. There are about 35 000 genes found in almost every healthy cell. Scientists are constantly conducting experiments on genes. Genetic modification is one of such experiments. Genetic modification refers to the deliberate alteration of the genetic structure or DNA of an organism in order to give it new abilities and produce a desired effect. Organisms that are modified with DNA from another organism are called

How are organisms adapted for efficient gas exchange? [25 marks] Many organisms have different features which enable them to survive and carry out gas exchange effectively. Single-celled organisms‚ such as bacteria and protozoa‚ are in constant contact with their external environment. For them‚ gas exchange occurs by diffusion across their membranes. Even in simple multicellular organisms‚ such as green algae‚ their cells may be close to the environment‚ and gas exchange can occur easily. In

Introduction: In this lab‚ I will study how muscles contract‚ what makes muscles contract‚ different types of muscle contraction‚ and learn about how resistance affects muscle contraction. I will define Key Terms that describe what will occur in the experiments; I will conduct an experiment for each Activity and provide all resulting Data as well as answer Questions from each Activity. I will then provide a short Summary for what I learned in each Activity. Key Terms: Recruitment (or Multiple
