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

The structure of an organisation refers to the pattern of relationships that exists between different parts of the business and between the different people who work within it. Organisations are structured in a variety of ways‚ dependant on their objectives and culture. The wrong organisation structure will hinder the success of the business. Internal factors such as size‚ product and skills of the workforce influence the organizational structure. As a business expands the chain of command will

Introduction A forest is a complex ecosystem which is predominantly composed of trees‚ shrubs and is usually a closed canopy. Forests are storehouses of a large variety of life forms such as plants‚ mammals‚ birds‚ insects and reptiles etc. Also the forests have abundant microorganisms and fungi‚ which do the important work of decomposing dead organic matter thereby enriching the soil. Nearly 4billion hectares of forest cover the earth’s surface‚ roughly 30 percent of its total land area.The forest ecosystem

by which the cytoplasm of a eukaryotic cell divides to produce two cells is called * cytokinesis. Eukaryotic cells spend most of their cell cycle in which phase? * interphase Chromatin‚ the stuff chromosomes are made of‚ is made up of what? * protein and DNA Which of the following occurs during interphase? * cell growth and duplication of the chromosomes The cell has a very narrow middle separating two bulging ends. It sort of looks like the number 8! Then you realize

P2: Outline the structure of the main tissues of the body. In this assignment I’m going to talk about the structure of the main tissues which are found within the body as well as what their role is in the terms of two named organs of the body. Tissues are a collection of similar cells that group together to carry out a specific function within the body. There are four different types of tissue found in the human body which include; epithelial tissue; connective tissue; muscle tissue and nerve tissue

How is the structure of cells related to their function? Cell structures come in various shapes and sizes dependent on their location within an organism and what life sustaining process it carries out. These can range from the globular protein of a red blood cell‚ designed to carry four oxygen molecules at a time to the tail like flagellum of a bacteria designed for mobility and penetration of organs within a body. There are two main types of cells‚ eukaryotic cells which are generally plant

Organelles are the various components of a cell with a specific structure and function and are linked to miniature organs. These include: Mitochondria: These are small components within cells that perform different important functions in order to keep the body healthy. They make the energy that cells need to do to work correctly. An example of this is brain cells which need a large amount of energy
