The boxes on the left describe processes carried out by cells. The boxes on the right contain the names of the cells that carry out these processes. Draw one straight line from each box on the left to a box on the right to link the process to the cell type. Draw six lines. An example has been done for you. transport of oxygen phloem sieve tube element red blood cell transport of sucrose phagocytosis palisade mesophyll cell platelets blood clotting production of glucose white blood cell root hair cell antibody formation absorption of mineral ions from the soil process cell type shows a section through part of a leaf. On draw: • a label line to identify one guard cell and label it G • a label line to identify one of the stomata and label it S. State one function of stomata.

This question is about neurones and reflex actions. Choose words from the list to complete the sentences. Each word may be used once, more than once, or not at all. endocrine fast impulses motor nervous receptor sensory slow stimuli synapses Neurones are cells that are part of the system. There are three types of neurone involved in a simple reflex action: a sensory neurone, a relay neurone and a neurone. The nerves conduct electrical . These are transmitted from one neurone to the next at junctions called . A reflex action is automatic, co-ordinated and .

Respiration releases energy. Write the word equation for aerobic respiration. shows the average daily energy requirement of different groups of males and females. 11 000 10 000 12 000 13 000 Key group description males females average energy requirement / kJ per day age 5 age 11 age 17 inactive adult active adult State the average energy requirement of a five-year-old female. kJ per day An eleven-year-old male received only 8000 kJ per day for four months. Use the data in to suggest two ways this could affect him. Use the data in to make three comparisons between the energy requirements of individuals aged 17 years and adults. Yeast cells can respire anaerobically. Biotechnology makes use of this. State two ways that the products of anaerobic respiration in yeast are used by humans.

The sentences in the box describe the feeding relationships between four organisms. Hawks obtain their energy from blackbirds. A fig tree carries out photosynthesis. Blackbirds are secondary consumers. Caterpillars are herbivores. Use the information in the sentences to write a food chain containing these four organisms. Do not draw pictures of the organisms. State the principal source of energy for this food chain. State the type of organism that gains its energy from dead organic material. A species becomes endangered when it is at risk of extinction. Explain two ways in which a species could become endangered. State one way in which endangered species can be conserved.

shows sections of two flowers, K and L, from the same species. flower K flower L On flower L in , identify and label an ovule and a petal. State the names of the parts in that: produce ovules protect the bud of the flower On , draw an arrow to represent the transfer of pollen from flower K to flower L during pollination. A student said, “Flowers K and L are pollinated by insects.” Describe two structures in flowers K and L that support this statement. Use features that are visible in . Describe the pathway water takes in a plant, as it moves from the soil to a leaf.

In an investigation, the carbon dioxide concentration in the air above a crop of maize plants was measured for 24 hours. There was no wind blowing during the 24 hours of the investigation. The results of this investigation are shown in . carbon dioxide concentration / arbitrary units time / hours sunrise sunset midday midnight midnight State the two times, on , at which the carbon dioxide concentration in the air was 37 arbitrary units. Calculate the difference in the carbon dioxide concentration in the air between 04:00 and 12:00 on . Space for working. arbitrary units Explain why the concentration of carbon dioxide decreases between 04:00 and 09:00. State two environmental factors that would affect the results of this investigation.

Selective breeding of animals is very important to farmers. Many different breeds of sheep have been produced by selective breeding. shows a flock of Merino sheep. This breed of sheep was produced by selective breeding. Sheep are important animals in many parts of the world as they produce meat, wool and milk. Table 10.1 describes some characteristics of five different breeds of sheep. Table 10.1 breed of sheep wool yield wool quality meat yield milk yield Arapawa average good poor average Awassi average poor average very good Blackbelly poor poor very good average Merino good very good good poor Tsurcana average good average average A farmer wants to sell both meat and wool. Suggest which breed of sheep in Table 10.1 is the most suitable for this farmer. Give a reason for your choice. breed of sheep reason Another farmer wants to produce a new breed of sheep with both a very good milk yield and a very good quality of wool. The farmer is able to buy any of the breeds of sheep shown in Table 10.1. Describe the process this farmer would use to produce the new breed of sheep on her farm.
