PRACTICAL 2 Title: Modelling of mitosis Objectives: To represent the pairs of homologous chromosomes by using pairs of model chromosomes. Introduction: Materials: 1. Noodles 2. Cutter Method: 1. The pair of model chromosomes is used to demonstrate how the two chromosomes line up at the beginning of mitosis. 2. After that the way of the sister chromatids of each chromosome separate into two separate chromosomes is demonstrated. 3. The spindle fibers that pull the sister chromatids apart is represented

Answer the following questions using 150 words each unless otherwise indicated. List the the source for your information and use your own words. Attach this assignment here as a word file by June 4th. 1. Discuss taxonomy (chapt. 1). What are the two disciplines involved? Who "invented’ modern taxonomy? What are the different levels of taxonomy? Taxonomy is the process or system of describing the way in which different living things are related by putting them in groups. The two disciplines

1. Eukaryotic cells have a true nucleus‚ bound by a double membrane. Prokaryotic cells have no nucleus. The purpose of the nucleus is to sequester the DNA-related functions of the big eukaryotic cell into a smaller chamber‚ for the purpose of increased efficiency. This function is unnecessary for the prokaryotic cell‚ because its much smaller size means that all materials within the cell are relatively close together. Of course‚ prokaryotic cells do have DNA and DNA functions. Biologists describe

Nucleus: The nucleus is the most obvious organelle in any eukaryotic cell. It is enclosed in a double membrane and communicates with the surrounding cytosol via numerous nuclear pores. Within the nucleus is the DNA responsible for providing the cell with its unique characteristics. The DNA is similar in every cell of the body‚ but depending on the specific cell type‚ some genes may be turned on or off - that’s why a liver cell is different from a muscle cell‚ and a muscle cell is different from a

Biological Science Lesson 1 Zoology - branch of biology that deals with the life of animals. 1. Morphology - studies forms and structure of animals. a. Gross anatomy - performs surgical technique ; dissection (cutting up). b. Paleontology - studies pre-historic forms of animals through fossil. 2. Histology - study of tissues & organs‚ their structure‚ functions & composition at a microscopic level. 3. Cytology - study of the structure & function and its parts at microsopic level or

All living things are made up of cells. It’s the smallest unit of life. When cells make up one big group of cells put together‚ the group is called tissue. Tissue makes up organs which eventually make up organ systems. There are 11 different types of organ systems throughout the human body. Some major organs systems are circulatory‚ respiratory‚ digestive‚ excretory‚ nervous and endocrine system.Why would a human dissect a chicken leg to learn about different types of tissue and blood vessels rather

The current evolutionary model has all forms of life originating from one original single celled microbial organism. The transition from microbes to life took roughly 3 billion years. The transition is rather intriguing as cells go from individual organisms into one large codependent ones that work together to ensure survival. Yet despite the difficulty to make that leap‚ many different organisms have made it successfully. Dr. Ratcliff wanted to study this very transition. In order to study

What I am comparing the structure of a cell to is a car. The reason I choose to do a car is because it is very similar to the structure of a cell and because to me it was the most interesting choice to choose from. Another reason I choose to compare the cell to a car is because it seemed to be the easiest one for me to do as compared to a Hogwarts or a city. Doing a house or a prison would have also been fairly easy but they were already picked by the people at my table. That wars why I choose to
