For temperature, blood glucose and water balance, trace stimulus, receptor, coordination, effector and response. Explain how negative feedback returns a variable toward its normal range.
Complete the missing stage in the negative-feedback loop and explain how it reduces the original change.
Colour the ecology illustration carefully and observe its key features.
Colour-code the balanced equation, leaf structures and three limiting-factor graphs, then annotate their functions.
GCSE Biology Revision Workbook is a five-mission activity book mapped to the DfE National Curriculum and GCSE Science specifications (Combined and Separate). Learners revise cell biology and microscopy, eukaryotic and prokaryotic cells, diffusion, osmosis and active transport, levels of organisation and enzymes, the digestive and circulatory systems, pathogens, the immune system, vaccination and antibiotics, photosynthesis and respiration, homeostasis, DNA, genes and chromosomes, inheritance and Punnett squares, natural selection and ecology. Every question is auto-marked on screen, or the whole book can be printed with a full answer key. Includes teacher, parent and pupil notes and is fully SEND-friendly with high-contrast and large-text modes.
Reproduction & Life Cycles KS3 is a five-mission Year 8 science activity book mapped to the DfE National Curriculum for KS3 biology (reproduction). Learners name the male and female gametes (sperm and egg/ovum), explain fertilisation and how the fertilised egg develops in the uterus during pregnancy, describe puberty and the menstrual cycle at a simple factual level, label the parts of a flower (stamen and carpel), and explain pollination, fertilisation and seed dispersal in plants. The content is clear, clinical and age-appropriate throughout. Every question is auto-marked on screen, or the whole book can be printed with a full answer key. Includes teacher, parent and pupil notes and is fully SEND-friendly with high-contrast and large-text modes.
Body Systems Detective KS3 is a five-mission Year 8 science activity book mapped to the DfE National Curriculum for KS3 biology: body systems. Pupils investigate the functions of the skeleton (support, protection, movement and making blood cells), work out how muscles pull in antagonistic pairs such as the biceps and triceps, identify hinge and ball-and-socket joints, put the digestive system in order and meet the enzymes that break down food, follow oxygen and carbon dioxide through the lungs, trachea, diaphragm and alveoli, and plan a balanced diet from its food groups. Every question is auto-marked on screen, or the whole book can be printed with a full answer key. Includes teacher, parent and pupil notes and is fully SEND-friendly with high-contrast and large-text modes.
Identify the missing or incomplete component in this ecology study plate, then colour-code the system.
Colour the photosynthesis illustration carefully and observe its key features.
Colour-code and technically annotate the key features of heart and circulation.
