Jazmeen Floyd IB Biology March 9‚ y The genetic disorder I choose was Smith-Magenis syndrome which is a developmental disorder that affects many parts of the body. This disorder occurs when the chromosome 17 gets deleted which contains the retinoic acid-induced 1 (RAI1) gene or due to mutation of RAI1 .It happens spontaneously at conception‚ which means it is almost never inherited. Some of the major symptoms that are brought forward with this disorder Distinct facial features brachycephaly which

Biology Key Questions – Lesson #1 1. How many electrons does Mg2+ have? Answer: Mg2+ has 10 electrons. A Magnesium atom has 12 electrons‚ 2 of which are valence electrons. The atom will lose the 2 outermost electrons in order to stabilize its electron shell. The nucleus maintains its 12 protons and becomes a Mg2+ ion. 2. Given that the half-life of the radioisotope carbon-14 is 5730 years‚ how useful do you think this isotope would be for dating bones that are over a million years

Matthew Nims Biology Honors Reflection 2nd nine weeks Period: 2 In this honors portfolio we created models of the cell cycle and used those models to create an animation. The purpose of this is to‚ first‚ memorize the visuals of the cell cycle. The Second is to understand what’s going on in the visuals by creating commentary to describe the changes from stage to stage. The third is to repeat the first and second by critiquing other videos. We used our understanding of mitosis that we

Organisms are made of cells that have similar structural characteristics 1.2.1 Outline the Historical development of the cell theory‚ in particular‚ the contributions of Robert Hooke and Robert Brown. • 1665 English scientist Robert Hooke used microscope to examine thin slices of cork and saw small box-like compartments he called cells. He was first to realise plant material had organised structure at microscopic level. (compound microscope) • 1831 Scottish Botanist

- BIOLOGY ASSIGNMENT Aim: To investigate the types of producers and animals in the tidal rock-shelf ecosystem and the adaptations of organisms in that environment. Also‚ to measure biotic and abiotic components and the distribution and abundance of organisms to the tidal rock- shelf ecosystem. Introduction: Long Reef Marine Reserve was established in the 1980’s to protect the extremely diverse marine life that makes the most of this environment. The Marine reserve covers the large rocky

March 5‚ 2013 Biology 1111 Term Paper Glycolysis and the Citric Acid Cycle Glycolysis occurs in the cytoplasm outside the mitochondria‚ it is a metabolic pathway that is the breakdown of glucose (C6) and ends with 2 pyruvate (C3) molecules. Energy is invested to activate the glucose‚ 2 ATP are gained‚ and oxidation results in NADH‚ which will be used later for additional ATP production. Glycolysis is divided into (1) the energy-investment step‚ when ATP is used; and (2) the energy-harvesting
