Jane put some fish in a tank and observed them over four weeks. She fed the fish with the same amount of food each day. She recorded the number of fish in the table below. Week 1: 5 fish; Week 2: 5 fish; Week 3: 8 fish; Week 4: 10 fish. Based on her observation at the end of week 4, what could Jane conclude about the fish?

A, B, C and D are four different things. Study the classification table below. The tick (✓) shows the characteristic each thing has. A: Can move ✓, Responds to changes ✓. B: Can move ✓, Needs air, food and water to stay alive ✓, Responds to changes ✓. C: Needs air, food and water to stay alive ✓, Responds to changes ✓, Can make its own food ✓. D: Responds to changes ✓. Which of the following is/are most likely a non-living thing(s)?

Study the chart below. The chart classifies Plants into two main groups: 'Flowering' and 'Heading T'. Under 'Flowering', plants are divided into 'Grow on land' (labelled 1) and 'Grow in water' (labelled 2). Under 'Heading T', plants are divided into 'Grow on land' (labelled 3) and 'Grow in water' (labelled 4). Using the chart above, circle the correct answer for (a), (b) and (c). (a) The diagram below shows a plant. The plant shown is (1 / 2 / 3 / 4). [1] (The diagram shows a banana plant/tree with a labelled fruit.) The table below shows two characteristics of plants P and Q. Plant P: Grow in water ✓, Reproduce by seeds ✗. Plant Q: Grow in water ✓, Reproduce by seeds ✓. (b) Plant P is (1 / 2 / 3 / 4). [1] (c) Plant Q is (1 / 2 / 3 / 4). [1] (d) What is a suitable heading for Heading T? Heading T: ____ [1]

Study the chart below. The chart is a classification flowchart for 'Things'. First question: 'Can make its own food?' If Yes, go to 'Does it reproduce by spores?' — if Yes → P, if No → Q. If No to the first question, go to 'Can move from place to place?' — if Yes → R, if No → S. (a) Draw a line to match each thing to the correct group. The things to match are 'cat' and 'fern' to one of P, Q, R or S. [1] (b) State the characteristics of S. [1] (c) Based on the chart above, state a similarity between P and Q. [1]
