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

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

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.

All organisms that are considered to be alive must possess certain key characteristics or functions. These include: order‚ response to the environment‚ reproduction‚ growth and development‚ regulation‚ energy processing and evolution. Since we recognize life by what living things do‚ these seven characteristics serve to define life. Organisms consist of one or more cells and while they may be very complex they are highly organized and coordinated. Inside each cell‚ atoms make up molecules.

Hypothesis * I feel the pH affected the enzyme activity to produce product. Prediction * If the pH affected the enzyme activity to produce product‚ then rate of reaction will change. Procedure * The procedure that we followed was to take two test tubes and label one pH2 and one pH10 and incubate 1 ml of each solution for 30 minutes. Then after 30 minutes we added a) 3.5 ml buffer b) 0.5 ml ONPG (substrate) c) 0.5 ml of the dilution that was incubated with the buffer (enzyme)

A hypothesis that passes is supported‚ but not proven. Why not? An alternative hypothesis might be the real explanation. The Experimental Method Experiments are designed to collect data or information to test specific hypotheses. Variables: factors that can change in value under different conditions Independent

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

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
