Introduction Last week‚ my Biology class and I went down to the Port Kembla Rock Platform. While we were there we surveyed five different sectors about the rock platform and recorded them‚ these included: 1. Surveying the abiotic characteristics of the rock platform 2. Observing the abundance and distribution of the Black Periwinkle (Nerita Atramentosa) 3. Observing the feeding relationships and food webs of the organisms 4. Finding the adaption’s of organisms 5. And Observing the human impacts

INTRODUCTION I. Have you ever wondered how the process of sexual reproduction begins in multi-cellular organisms such as ourselves? II. It all begins through a cell division process known as meiosis. III. I am currently a biology major at CSU-Pueblo looking to pursue a degree in wildlife biology. IV. During the process of meiosis‚ diploid cells split in half‚ forming four haploid cells‚ which each have a single set of chromosomes. These cells are called either gametes or sex cells. Female gametes

The article “Biology is Beauty” by Geoffrey Cowley touches on the aspects behind beauty. The article states that everyone shares a sense of what is attractive. Basically‚ Cowley is stating that people are attracted to what is on the outside‚ even if we do not know it. Even though points of attraction can vary over societies‚ beauty is an innate quality we all think of. The article touches on a few examples that the author feels explains. First‚ Cowley says that humans love symmetry; people prefer

Before watching the film I did not think biology had anything to do with racism. I believe scientist tried to prove that race was biological in order to justify the actions against the non-white race. I had never really thought about where race had come from but was surprised‚ but not hard to believe‚ to hear in the film that race was created by humans to describe social and cultural differences. Knowing that race is not biological will not eliminate racisms today. Those that are racist today

Title: Diffusion throughout the membranes Lab Partner(s): Alexis Clouting Date: 2/15/15 Abstract: In the content of the Module 2 we learned about Diffusion across cell membranes. We touched on the different types of cells and their functions. How things are transported in and out of cells. Learning about isotonic‚ hypertonic and even hypotonic solution. This is not my first time touching on this subject in my nursing career and I learned a way to remember what happens in the different solutions

GCSE Biology This blog will cover and explain the specification for Edexcel triple science course 2013 for biology. Hope it helps :) Monday‚ 20 May 2013 3.33 understand that the incidence of mutations can be increased by exposure to ionising radiation (for example gamma rays‚ X-rays and ultraviolet rays) and some chemical mutagens (for example chemicals in tobacco). There are things that make you more likely to have a mutated gene‚ these include: ionising radiation and chemical mutagens like

Is gene therapy the most effective way to treat depression? What really is depression? The term ‘depression’ can be defined in two different ways: 1. Severe despondency and dejection‚ accompanied by feelings of hopelessness and inadequacy. 2. A condition of mental disturbance‚ typically with lack of energy and difficulty in maintaining concentration or interest in life.1 Majority of people believe that depression is somewhat trivial and is not regarded as a genuine health condition‚ but

cells to join the symplast pathway before passing through the endodermis The role of the Casparian strip: It blocks the apoplast pathway between the cortex and xylem Ensuring that water/nitrate ions pass into the cell cytoplasm through the cell membrane Nitrate ions are actively transported from the cytoplasm of the cortex cells into the xylem This lowers the water potential in the xylem so

aerobic respiration in plants and animals e.g. germinating seeds and mealworms Bio Experiment : Comparing Rate of respiration in mealworms at different temperatures? Mealworms are cold-blooded animals and are unable to maintain a constant core temperature‚ hence respiration would therefore change with temperature. As glucose is oxidised‚ oxygen is used up and carbon dioxide and heat energy is produced. Increment in temperature / production of CO2 or O2 consumption would hence be good indicators
