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

hair colour are in the cytoplasm. These chemicals are the basic living materials that a cell needs. 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

Describe and discuss at least two features of the psychodynamic approach. (10 marks) One main feature is the defence mechanisms. One assumption of the psychodynamic approach is that the personality is split into three parts; the id‚ the ego and the superego. Defence mechanisms are an unconscious response used when the ego is in conflict with the id and the superego and they prevent the ego from harm. There are four main defence mechanisms; Denial‚ Displacement‚ Rationalisation and Sublimation.

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

A planarian is free-living flatworm that lives in fresh water. Planarians are organisms that live in freshwater. Planarians are part of the metazoan phylum. Animals in the metazoan like jellyfish have the ability to regenerate (Raymond 511-512). Planarians are closely related to animals like jellyfish and starfish. These animals shared the same special ability to regenerate; starfish are able to regenerate their arm when it is cut off. Jellyfish are able to regenerate their stinger when cut off (Li

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

Classically‚ there are four main types of market: Perfect Competition‚ Monopolistic Competition‚ Oligopoly and Monopoly. They differ in terms of firm’s size and number‚ the barriers of entry and exit‚ the degree to which firms ’ products are differentiated‚ and the extent of information transparency‚ which is the availability of information to both
