Biological Approach | PY1 PY1 | Model answers for biological approach | Sumi Prasobh AS Level | 1a) Outline two assumptions of the biological approach (4 marks) One assumption of the biological approach is that our personalities and behaviors are biologically determined. Lab research found that we’re a product of our brain structure. The balance of neurotransmitters, such as dopamine and adrenaline has directly been found to affect our mood, thoughts and personalities. For example Hans Selye found that both humans and animals are biologically determined to react in the same predictable way to the threat of a stressor for aiding survival. Another assumption is that certain regions of the brain determine certain behaviors.
These biological factors are said to determine an individual’s development and characteristics . the ability to speak a first language are thought to be due to an in progress genetic inheritance. Genes provide the instructions for structuring amino acids which in turn influence the proteins within our body cells. Genes process the chemical basis of our biology. Depending on the genes we inherit and the environmental influences we are exposed to, we will act apon a situation differently.
Unit 4, P2 Leah-Faith Giles Understand the potential effects of life factors and events on the development of the individual. Life Factors Within each living cell in the human body, there is a nucleus, with 23 pairs of chromosomes inside it. For each pair of chromosomes one comes from the mother, and another pair from the father. These chromosomes carry units of inheritance called genes. These genes carry the instructions to build a new person; they are made up of a substance called deoxyribonucleic acid, commonly known as DNA.
Discuss, in detail, all the genetic and cellular events encompassed in the clonal selection theory of lymphocyte development. 5. Discuss the various ways by which antibodies interact with
Describe in detail the phases of mitosis. What are the significant events that occur in each phase? What are chromatids? When do chromatids become chromosomes in Mitosis? What is cytokinesis?
The biological approach is shown to be one of the most scientific explanations for human behaviour. The key assumptions suggest human behaviour is strongly determined by our genes, biological processes (chemical imbalances, fight/flight responses), and genetic inheritance. The nervous system also has an essential role, especially the brain and central nervous system, where each structure has an important function in the control of behaviour and thoughts. The central nervous system is split into the spinal cord and brain, and is concerned with all life functions and psychological processes. The peripheral nervous system, also part of the nervous system, transmits information to and from the nervous system.
It does this by controlling the enzymes present. The chromatin is composed of DNA. DNA contains the information for the production of proteins. | Mitochondria | Mitochondria have two membranes (not one as in other organelles). The outer membrane covers the organelle and contains it.
1. Bacterial resistance to antibiotics 2. Comparative biochemistry 3. The fossil record ANSWER: A) max 7 pts The Big Picture: 1 pt- punctuated equilibrium, mass extinction, etc 1 pt- definition of evolution- change through time 1 pt- mutation- change in gene yields genetic variation 1 pt- natural selection/selective pressure (Darwin) 1 pt- genetic variation exists 1 pt- over production 1 pt- competition – survival of fittest (best genes) 1 pt- survivors reproduce (best
PSYCH 100 – EXAM 1 * What are the goals of psychology? Description, explanation, prediction, control. * Understand the distinction between nativism/empiricism (nature/nurture). Nativism – we are born with out personalities and everything is ingrained in our biology. Empiricism – everything is learned and needs to be adapted to * Know the difference between structuralism/functionalism.
The Biopsychological Process How does biology (brain, nervous system, hormones, etc) influence / affect human behavior? Psychology’s Three Main Levels of Analysis (BIOPSYCHOSOCIAL APROACH) Biological Perspective – Can produce relevant information into human actions. – Physical / biological bases of human and animal behavior FACTOR I: Genetics FACTOR 2: Nervous system FACTOR 3: Endocrine System GENETICS: Trait transmission TRAIT ( is the observable or quantifiable expression of one or more genes. – a distinguishing quality or characteristic. MIRRORING: LITANY of TRAITS and CHARACTERISITCS: HEREDITY ( Transmission of traits and characteristics from parent to offspring.
