Test Wednesday 18th November
On everything done so far this year...
3.23 understand that division of a diploid cell by mitosis produces two cells which contain identical sets of chromosomes
3.24 understand that mitosis occurs during growth, repair, cloning and asexual reproduction
3.25 understand that division of a cell by meiosis produces four cells, each with half the number of chromosomes, and that this results in the formation of genetically different haploid gametes
3.26 understand that random fertilisation produces genetic variation of offspring
3.27 know that in human cells the diploid number of chromosomes is 46 and the haploid number is 23
3.13 understand that the nucleus of a cell contains chromosomes on which genes are located
3.14 understand that a gene is a section of a molecule of DNA and that a gene codes for a specific protein
3.15 describe a DNA molecule as two strands coiled to form a double helix, the strands being linked by a series of paired bases: adenine (A) with thymine (T), and cytosine (C) with guanine (G)
3.16 understand that genes exist in alternative forms called alleles which give rise to differences in inherited characteristics
3.17 understand the meaning of the terms: dominant, recessive, homozygous, heterozygous, phenotype, genotype
3.21 understand that the sex of a person is controlled by one pair of chromosomes, XX in a female and XY in a male
3.22 describe the determination of the sex of offspring at fertilisation, using a genetic diagram
3.9 understand the roles of oestrogen and progesterone in the menstrual cycle
2.90 understand the sources, roles and effects of the following hormones: ADH, adrenaline, insulin, testosterone, progesterone and oestrogen.
2.77 understand that organisms are able to respond to changes in their environment
2.78 understand that homeostasis is the maintenance of a constant internal environment and that body water content and body temperature are both examples of homeostasis
2.68 recall that the lungs, kidneys and skin are organs of excretion
2.69 understand how the kidney carries out its roles of excretion and osmoregulation
2.70 describe the structure of the urinary system, including the kidneys, ureters, bladder and urethra
2.71 describe the structure of a nephron, to include Bowman’s capsule and glomerulus, convoluted tubules, loop of Henlé and collecting duct
2.72 describe ultrafiltration in the Bowman’s capsule and the composition of the glomerular filtrate
2.73 understand that water is reabsorbed into the blood from the collecting duct
2.74 understand that selective reabsorption of glucose occurs at the proximal convoluted tubule
2.75 describe the role of ADH in regulating the water content of the blood
2.76 understand that urine contains water, urea and salts.
3.1understand the differences between sexual and asexual reproduction
3.2 understand that fertilization involves the fusion of a male and female gamete to produce a zygote that undergoes cell division and develops into an embryo.
3.8 describe the structure and explain the function of the male and female reproductive systems
3.12 understand the roles of oestrogen and testosterone in the development of secondary sexual characteristics.
