Describe the structure and function of the skeleton system’s two distinct are – Axial System and Appendicular skeleton. Axial system The axial skeleton is the portion of the human skeleton that consists of the bones of the head and trunk of an organism. In the human body‚ it consists of 80 bones and is composed of – 29 bones in the head - (8 cranial and 14 facial bones) and then also 7 associated bones (6 auditory ossicles and the Hyoid Bone) 25 bones of the thorax - (the sternum and 24 ribs)

Human Biology Unit 1 Assignment. A cell is a small membrane enclosed structure filled with an aqueous solution where the organelles are found. Organelles are small structures within cells that perform dedicated functions. All eukaryotic cells have the following organelles: Nucleus‚ Ribosomes‚ Lysosomes‚ Cytoplasm‚ Nucleolus‚ Cell Membrane‚ Mitochondria‚ Endoplasmic Reticulum (ER) and Golgi Body. Insulin is a protein compound made up of more than one chain of amino acids. Amino acids are the building

healthy and in shape therefore learning more about the muscular system is very interesting. The reproductive system is another wonderful system to study and learn about‚ it is a great part of human life. I find it amazing to learn about the structure and functions of these two body parts and how they actually work together to perform homeostasis. We have so many muscles in our muscular system‚ too many to list. There are three main types of muscles. Cardiac muscles‚ skeletal muscles and smooth muscles

The Structure and Function Relationships of Proteins Proteins are a group of organic compounds whose molecules consist of carbon‚ hydrogen‚ oxygen‚ nitrogen and sometimes sulfur atoms. They are condensation polymers of amino acids that are joined by strong peptide bonds. There are 20 different types of amino acids available‚ and the different combinations of these amino acids give it different structures and specific functions to it. Below in this essay‚ will illustrate the how different structure

Page 1 of 8 BIOLOGY 12- CELL STRUCTURE & FUNCTION Chapter Notes THE CELL THEORY • Although different living things may be as unlike as a violet and an octopus‚ they are all built in essentially the same way. The most basic similarity is that all living things are composed of one or more cells. This is known as the Cell Theory. • our knowledge of cells is built on work done with microscopes • English scientist Robert Hooke in 1665 first described cells from his observations of cork slices

The basic structure of all the penicillins consists of a thiazolidine ring fused with a beta-lactam ring‚ creating a fundamental nucleus (also known as 6-amino penicillanic acid) crucial for their antibacterial activity. A wide variety of semisynthetic penicillins are produced by altering the composition of the side chains attached to this nucleus.The molecular formula of penicillin is C16H18N2O4S and weight of 334.39 g/mol‚ each base with a variable side chain‚ “R” that differentiates the penicillins

Functions and structure of plant terpenes Terpenes are an enormous class of organic compounds‚ that are produced by a wide variety of plants and fungi‚ especially conifers. Terpenes are also produced by some of the living organisms‚ like swallowtail butterflies. They emit terpenes from their osmeterium. Terpenes are important materials for a plant as components of its body and as a material to protect it from external enemies since it has a strong smell and colorless. Terpenes are found in biological

Cellular organelle structure and function Nucleus The Nucleus is comprised of the pore perforated nuclear membranes‚ nucleoplasm‚ chromatin and the nucleolus at the core. The nuclear envelope consists of an inner and outer membrane that forms the outer structure. Contained within the nuclear membrane are nucloplasm which is the fluid medium in which the chromatin is present‚ chromatin being the genetic material. At the core of the nucleus is the nucleolus‚ where ribosomes are synthesized. The
