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

Michael J. Behe wrote this book to show that Darwinism is not consistent with what we now know about biochemistry. The book is a daring attempt to re-establish the argument for design in living things. Chapter three is all about how molecule machines operate a cell. According to the book‚ these molecules are mostly made up of proteins and proteins carry out chemical reactions. They are very multitalented but they typically have one use or at most a very little. Each cell has thousands and thousands

Introduction: Hurler Syndrome (MPS-I)‚ otherwise classified as Mucopolysaccharidosis‚ is the most severe form of this disease and is caused by cells being unable to break down dermatan sulfate and heparan sulfate during regular metabolism(Laberge‚ 2010). The build up of these two by-products disturbs regular cell functionality and this may cause damage within the tissues of organs (Laberge‚ 2010). Two major symptoms found within an individual with Hurler Syndrome are skeletal deformities and

Unit 2 Lecture Study Guide 1) What are the parts of an atom? Where are the subatomic particles found? The atoms are the smallest units of matter with their own chemical characteristics. The atoms are divided into 2 parts. The first part is the central nucleus and the electron cloud. The central nucleus contains very heavy particles and the electron cloud contains very light moving particles. The subatomic particles are the protons‚ neutrons‚ and the electrons. They are located

Question 3: Write short notes on the following. (a) Cytoplasm (b) Nucleus of a cell Answer: (a) Cytoplasm: It is a fluid that fills the cell and occurs between the plasma membrane and the nucleus. Cell organelles such as mitochondria‚ ribosomes‚ Golgi bodies‚ etc. are suspended in the cytoplasm. http://schools.aglasem.com/?p=2307 2/8 8/17/2014 NCERT Solutions for Class 8th Science Chapter 8 Cell-Structure and
