Biology: Advanced
Class 12 biology, worked properly: crosses, DNA and the gene you can actually move.
What you'll learn
- ✦Explain a flower's adaptations for pollination and trace the stages of double fertilisation in a flowering plant
- ✦Describe the human reproductive systems, the menstrual cycle, and the biology behind common reproductive health choices, from contraception to assisted reproduction
- ✦Work out a monohybrid or dihybrid cross's result and read a family pedigree to trace how a trait is inherited
- ✦Describe the structure of DNA, explain how it copies itself, and how a gene's code is read into a protein
- ✦Explain the evidence for evolution and the mechanisms, including natural selection and genetic drift, that change a population's gene pool over generations
- ✦Diagnose a common disease by its cause and explain how the body defends itself, from immunity to helpful microbes
- ✦Explain how a gene is moved into an organism by genetic engineering and describe one medical and one agricultural use of biotechnology
- ✦Explain how population interactions, energy flow and nutrient cycles shape an ecosystem, and describe one real measure to conserve biodiversity

Syllabus
Module 1 · 24m
Reproduction Free

- Can explain the biology behind common reproductive health choices
Module 2 · 24m
Genetics Locked
What you'll be able to do
- Can work a monohybrid or dihybrid cross and read a pedigree, and explain linkage
- Can describe DNA's structure and explain how it replicates
- Can explain how a gene's code is transcribed and translated into a protein
Module 3 · 24m
Evolution Locked
What you'll be able to do
- Can state the evidence for evolution and explain what the Hardy-Weinberg principle tests
- Can explain natural selection, genetic drift and the other mechanisms that change a population
- Can explain human evolution as shared ancestry, not descent from living apes
Module 4 · 24m
Human Health Locked
What you'll be able to do
- Can diagnose a common disease by its cause and explain how immunity and vaccination protect the body
- Can name microbes that help us, from fermented food to antibiotics
- Can explain how drugs and alcohol affect the body and why willpower alone is not the story
Module 5 · 24m
Biotechnology Locked
What you'll be able to do
- Can explain how a gene is cut, carried and inserted into a host organism
- Can describe one medical use of biotechnology, such as recombinant insulin
- Can describe one agricultural use of biotechnology, such as Bt cotton
Module 6 · 24m
Ecology Locked
What you'll be able to do
- Can explain how populations interact and grow, and predict a predator-prey cycle's shape
- Can explain why energy flows one way through an ecosystem while nutrients cycle
- Can describe one in-situ and one ex-situ way to conserve biodiversity
