NSSCO Biology 6116 study plan

Identify independent, dependent and controlled variables and write a testable hypothesis for four NSSCO-style scenarios, including an osmosis experiment using potato tissue.

Draw and label a plant cell and an animal cell from memory and state the function of the nucleus, mitochondrion, chloroplast, cell wall, vacuole, ribosome and cell membrane.

Compare diffusion, osmosis and active transport in a table covering direction of movement, energy requirement, membrane involvement and one biological example of each.

Describe the stages of mitosis in order and explain why uncontrolled mitosis can produce tumours.

Calculate total magnification and convert measurements between mm and micrometres using standard form.

Write the word and balanced symbol equations for photosynthesis and aerobic respiration, and state the organelle and tissue where each takes place.

Design and evaluate an experiment on light intensity and the rate of photosynthesis in pondweed, naming the limiting factor at each light level.

Explain the roles of nitrate and magnesium ions in plants and predict the deficiency symptoms of each.

Break a named meal into its nutrient groups, then identify the enzyme, product and site of digestion for each, explaining the effect of temperature and pH on enzyme activity.

Label the human alimentary canal and explain how villi structure relates to efficient absorption.

Explain how root hair cells and the transpiration stream move water and mineral ions from soil to leaf, and describe how stomata and guard cells regulate water loss.

Draw and label the heart, describe the cardiac cycle and relate the structure of arteries, veins and capillaries to their functions.

Calculate cardiac output from heart rate and stroke volume, and interpret given data on exercise and blood pressure.

Describe the nephron and explain ultrafiltration, selective reabsorption and osmoregulation by the kidney.

Explain how negative feedback controls body temperature and blood glucose, naming the effectors involved.

Define and correctly apply population, community, ecosystem, habitat, niche and trophic level to one named local ecosystem.

Construct and interpret food chains, webs and pyramids of number and biomass, and calculate the percentage energy transferred between trophic levels.

Describe the carbon and nitrogen cycles, naming the organisms and processes at each stage.

Analyse the effects of deforestation, eutrophication, pesticide use and greenhouse gases on ecosystems, and evaluate one named conservation measure.

Describe how quadrats and transects are used to sample populations and state how sampling is made random.

Trace a reflex arc from stimulus to response, labelling receptor, sensory neurone, relay neurone, motor neurone, effector and synapse.

Compare nervous and hormonal control in terms of speed, duration and pathway, and describe how adrenaline and insulin act on named target organs.

Explain phototropism and gravitropism in terms of auxin distribution and describe one experiment demonstrating each.

Label the human reproductive systems and describe gamete formation, fertilisation, implantation and the roles of oestrogen, progesterone, FSH and LH in the menstrual cycle.

Describe how the placenta and amniotic fluid support the fetus and evaluate two methods of contraception plus one STI prevention strategy.

Solve monohybrid crosses using Punnett squares, including sex determination and test crosses, and state genotype and phenotype ratios.

Explain how meiosis, mutation, crossing over and random fertilisation produce genetic variation.

Distinguish continuous from discontinuous variation and explain natural selection using one named example such as antibiotic resistance.

Evaluate one applied genetics technique (selective breeding, cloning or genetic engineering) by stating benefits, risks and ethical concerns.

Identify sources of error in given data and suggest a specific improvement to the method.

Compare aerobic and anaerobic respiration in humans and yeast, including equations, products and ATP yield.

Explain gas exchange in alveoli and in leaves, and interpret given lung-volume or spirometer data.

Re-derive kidney function, thermoregulation and reflex arc content from memory and correct every gap found against notes.

Answer 20 short-answer recall questions across these three domains in 25 minutes without notes.

Sit two full-length timed papers under exam conditions, one early in the week and one at the end.

Mark both against the mark scheme, tag every lost mark by domain and by error type, and rank the three weakest areas.

Re-teach and re-test those three weak areas using flashcards and a 10-question mini-test for each.

Practise the command words state, describe, explain, suggest and evaluate on ten question stems so that answer depth matches the mark tariff.
