Frequently asked questions
What is Inheritance, variation and evolution?
Inheritance, variation and evolution covers Reproduction, Variation and evolution, The development of understanding of genetics and evolution, and Classification of living organisms in GCSE AQA Foundation Combined Science Biology. 26 lessons in 4 subtopics.
What is MRSA?
MRSA (methicillin-resistant Staphylococcus aureus) is a strain of Staphylococcus aureus bacteria that has evolved resistance to methicillin and many other commonly used antibiotics. The How Antibiotic Resistance Develops notes cover this in full.
What are genes?
Genes are sections of DNA that control the development of specific characteristics and are passed from parents to offspring. The Darwin's Theory and Modern Evidence notes cover this in full.
What is a fossil?
A fossil is the preserved remains or traces of organisms that lived millions of years ago, found in rocks. The What are fossils and how are they formed? notes cover this in full.
When did the dodo go extinct?
The dodo went extinct in 1681, within 200 years of humans arriving on Mauritius. The Understanding Extinction and Its Causes notes cover this in full.
What are gametes?
Gametes are specialised reproductive cells that contain half the normal number of chromosomes (haploid). The Gametes in Sexual Reproduction notes cover this in full.
What is a genome?
A genome is the entire genetic material of an organism. The DNA Structure and the Genome notes cover this in full.
What is evolution?
Evolution is a change in the inherited characteristics of a population over time through a process of natural selection, which may result in the formation of a new species. The What is Evolution? notes cover this in full.
What is the scientific name for humans?
The scientific name for humans is Homo sapiens: Homo is the genus, written with a capital letter, and sapiens is the species, written in lowercase. The The Linnaean Classification System notes cover this in full.
