Intermediate 2 Biology
Students would normally be expected to have attained a General award (KU and PS) in Standard Grade Biology or Intermediate 1 Grade A
There are 3 units:
1. Living Cells
o Cell structure and function
The differences between plant, animal and microbial cells. The functions of cell structures The commercial use of cells in brewing, baking, alternative fuel and antibiotic production.
o Diffusion and osmosis in plant and animal cells
o Enzyme action
o Aerobic and anaerobic respiration
Release of energy from glucose.
The role of ATP.
The products of aerobic and anaerobic respiration
2. Environmental Biology and Genetics
Ecosystems and energy flow, food chains and webs.
Adaptation to the environment and competition between species
o Factors affecting variety within species
Fertilisation Genetics (monohybrid inheritance, polygenic inheritance, selective breeding, natural selection, genetic engineering etc)
3. Animal Physiology
o Mammalian nutrition
Food tests, energy from food structure and function of the gut, digestion
o Control of the internal environment
Structure and function of the kidneys, role of ADH, negative feedback control and osmoregulation in fish
o Circulation and gas exchange.
Structure and function of the heart and blood vessels. Structure and function of the lungs and gas exchange. Composition of blood
o Sensory mechanisms and processing information
Structure and functions of the brain and spinal cord Reflex actions Temperature control by negative feedback control.
Students are required to pass three end of unit assessments during the session, complete a prelim examination during the spring term and submit an Investigation report. An overall Intermediate 2 Biology award comprises three units passes, an investigation report and satisfactory completion of a national SQA examination.
Regular completion of homework assignments is essential to consolidate class work. Assignments include KU and PS questions, extended response writing and data interpretation. In addition students are expected to read over their notes and relevant sections of the text book regularly and learn their work thoroughly. Students have access to the pupil server in school and VLE (www.fronter.com/qahs) in school or at home.
Higher Biology or Higher Human Biology. Use of the Intermediate 2 award as a qualification for entry into Further Education science courses such as HNC. Use of the Intermediate 2 award as part of a broad education or to seek employment.
