Genetics Basics

Practise cell biology — cell theory, animal and plant cells, organelles and their jobs, prokaryotes vs eukaryotes, using a light microscope and magnification arithmetic, specialized cells, levels of organization, and diffusion and osmosis basics. The score reports correct answers in this round, not overall biology ability.

Trace energy flow through a food web and reason about producers, consumers, decomposers, and population effects. The score reports correct answers in this round, not overall ability; population-change answers are conditional consequences of the stated model, not predictions for a real ecosystem.

Practise how the human body works, system by system — circulatory, respiratory, digestive, nervous, skeletal, muscular, immune, urinary, endocrine, and the senses and skin. The score reports correct answers in this round, not overall biology ability.

Practise school plant biology — the photosynthesis word equation, chloroplasts and leaf structure, limiting factors, gas exchange and respiration, xylem and phloem, transpiration, roots and minerals, flowers, pollination, seeds and germination. The score reports correct answers in this round, not overall biology ability.
