State the word equation for aerobic respiration. + + Organisms carry out aerobic respiration to release the energy they need to stay alive. State three processes that humans carry out using this released energy. An investigation was carried out on two students. Each student breathed out as much air as possible, as quickly as possible. The volume of expired air and the time taken were measured. shows the results of the investigation.    YROXPH RIH[SLUHG DLUGP WLPHV IHPDOH          PDOH State the volume of air expired by the female student and the amount of time she took to breathe out as much air as possible. volume dm3 time taken s State one difference and one similarity shown in between the results for the male and female students. difference similarity This investigation was also carried out on another male student who had smoked cigarettes each day for the last four years. Suggest one way in which the results for this student would be different to those of the male student who did not smoke. State two components of tobacco smoke that can damage the body. Complete Table 2.1 by stating three ways in which anaerobic respiration is different to aerobic respiration in animal cells. Table 2.1 way in which anaerobic respiration is different to aerobic respiration in animal cells Yeasts carry out anaerobic respiration. State two ways in which humans make use of this process.

Each word may be used once, more than once or not at all. diploid embryo haploid ovary oviduct semen sperm testis ureter urethra zygote In humans, the female gamete is the egg and the male gamete is the . Both gametes are cells. An egg is produced by an and passes along an to reach the uterus. When humans reproduce, their gametes fuse to form a cell called the .

shows a photograph of some red blood cells, taken through a microscope. Explain how the features of a red blood cell given in Table 5.1 are important to its function. Write your answers in Table 5.1. Table 5.1 feature of red blood cell explanation of importance contains haemoglobin no nucleus present very tiny cell Blood is made up of four major components. Two of these components are plasma and red blood cells. Name the two other major components of blood and state their function. name function name function

shows a diagram of the reproductive organs of a wind-pollinated flower. RYDU\ VWDONRIVWDPHQ ILODPHQW State three ways in which the reproductive structures of this flower are different to those of an insect-pollinated flower. Write your answers in Table 10.1. Table 10.1 structure wind-pollinated flower insect-pollinated flower anther stalk of stamen stigma State three ways in which an insect-pollinated flower attracts insects. The pollen grains of wind-pollinated flowers and insect-pollinated flowers are different. Suggest one feature that would help pollen grains be dispersed by wind.

Define these genetic terms: meiosis chromosome. The petal colour in a species of plant can be blue or white. The allele for blue petals is dominant to the allele for white petals. The allele for blue petals is represented by B and the allele for white petals is represented by b. Two heterozygous blue plants were crossed. Complete to show the results of this cross.
