is a diagram of a plant cell. E D C B A The boxes on the left contain the letters that identify some parts of the plant cell in . The boxes on the right show the functions of some parts of a cell. Draw five lines to link each letter to its correct function. letter from function contains the genetic material A controls which substances enter and leave the cell B filled with sap to support the cell C strengthens the cell D transports nerve impulses E where photosynthesis occurs State the names of two different types of plant cell. A student used a potato as a source of plant tissue. The student cut six cylinder-shaped pieces from the potato. Each potato cylinder had the same diameter. Each potato cylinder was immersed in either water or one of five different concentrations of sugar solution. The student measured the length of the potato cylinders before immersion and after being immersed for 30 minutes. Table 1.1 shows the results. Table 1.1 concentration of sugar solution / mol per dm3 length of potato cylinder before immersion / mm length of potato cylinder after immersion / mm change in length of potato cylinder / mm 0.0 49.5 52.0 + 2.5 0.2 50.0 52.0 + 2.0 0.4 50.5 51.5 + 1.0 0.6 50.5 51.0 + 0.5 0.8 50.0 49.0 1.0 50.0 48.5 – 1.5 Use the information in Table 1.1 to calculate the change in length of the potato cylinder immersed in the 0.8 mol per dm3 sugar solution. mm Use the information in Table 1.1 to calculate the percentage increase in length of the potato cylinder immersed in the 0.2 mol per dm3 sugar solution. % State the name of the process that causes water to enter or leave the potato cells. Describe the expected change in appearance of a potato cell that was immersed in a 1.0 mol per dm3 sugar solution.

State the total percentage using surgical methods of birth control in . % State two forms of natural birth control. State the type of contraception shown in , that also protects against the spread of sexually transmitted infections (STIs). HIV infection is an example of an STI. State the name of the type of pathogen that causes an HIV infection. Describe how HIV can be transmitted.

The inheritance of coat texture in guinea pigs is controlled by a single gene. Define the term gene. shows a photograph of a guinea pig with a rough coat and a guinea pig with a smooth coat. smooth coat rough coat The allele for a rough coat is dominant and represented by the letter R. The allele for a smooth coat is recessive and represented by the letter r. is a pedigree diagram showing the inheritance of coat texture in some guinea pigs. Key: male RR male Rr male rr female RR female Rr female rr generation 1 generation 2 A B C D E F State the total number of guinea pigs with smooth coats in . State the letter of a guinea pig that has a homozygous dominant genotype in . State the total number of male guinea pigs in . Two guinea pigs are bred together. • The genotype of the male guinea pig is RR. • The genotype of the female guinea pig is Rr. Complete to show the: • possible genotypes of the offspring from this cross • the probability of offspring having a smooth coat. male female probability of offspring having a smooth coat Complete the sentence about breeding. Two identical homozygous individuals that breed together will be -breeding.

On : • Circle a part that releases egg cells. • Draw a label line and the letter W to show where fertilisation occurs. • Draw a label line and the letter X to show where the fetus develops. State the name of the process that produces egg cells. State the names of two parts of the female reproductive system that sperm must pass through to reach the egg cell. is a graph showing the changes in the thickness of the uterus lining during a menstrual cycle. thickness of the uterus lining day of the menstrual cycle Use the information in to state the number of days during which the uterus lining is shed. Draw a line to complete the graph in to show the thickness of the uterus lining between day 16 and 28. State the day of the menstrual cycle when eggs are released. The menstrual cycle is one of the changes that happens to girls during puberty. Describe the changes that occur in boys during puberty.

is a diagram of the human gas exchange system. ………………………………… ………………………………… ………………………………… ………………………………… ………………………………… The list shows the names of some of the parts of the human gas exchange system. alveolus bronchiole bronchus diaphragm larynx rib trachea Use the words from the list to label . You do not need to use every word. Write your answers on the answer lines provided in . State the name of the part of the body through which air enters and leaves. Complete the sentences about the differences between inspired and expired air. Inspired air contains oxygen than expired air. Inspired air contains carbon dioxide than expired air. The concentration of water in inspired and expired air varies. Carbon dioxide is one of the components of inspired and expired air. State the name of the chemical used to test for the presence of carbon dioxide.

A scientist measured the mass of carbon dioxide produced by anaerobic respiration in yeast cells for 1200 minutes. shows the results. total mass of carbon dioxide produced / g time / minutes Complete the sentences to describe the results shown in . The yeast cells produced a total of g of carbon dioxide during 1200 minutes. The yeast cells stopped producing carbon dioxide at minutes. The investigation was repeated with boiled yeast cells. Predict the effect on the mass of carbon dioxide produced and explain your prediction. State the name of one other product of anaerobic respiration in yeast cells. The box on the left contains the term ‘Respiration’. The boxes on the right contain sentence endings. Draw two lines to join the term ‘Respiration’ to two boxes on the right to make two correct sentences. always produces carbon dioxide. is necessary for diffusion. Respiration occurs only in animals. releases energy. uses glucose. State one substance required for aerobic respiration that is not required for anaerobic respiration.
