25
Gene Therapy
where someone’s genetic code is edited to treat or cure illness or genetic disorder
26
Giardia
a communicable bowel infection caused by a single celled protists called parasite G intestinalis, can infect other animals
27
Gonorrhoea
a sexually transmitted disease usually caused by having unprotected sex, rarely has symptoms, may cause ectopic pregnancies
28
Health
a person's mental and physical condition, not simply the absence of illness
29
Helicopter Pylori
an acid-tolerant bacteria that forms stomach ulcers and, in severe cases, stomach cancer
30
HIV
Human Immunosuppressant Virus the virus that causes AIDS, caused by unprotected sex, destroys white blood cells and causes the immune system to be badly damaged
31
Iron Deficiency
leaves young leaves with green veins despite a yellow/white colour
32
Lifestyle Diseases
diseases caused partly by unhealthy behaviour and partly by other factors, e.g. gout, type 2 diabetes
33
Magnesium Deficiency
causes leaves to turn yellow in plants, leaving the veins green as magnesium is needed to create chlorophyll
34
Malaria
a communicable disease caused by protists found in the mosquito bite, which affects the liver and blood cells, can stay dormant in the body for years after being infected
35
Malignant Tumour
a tumour that spreads through the body by having bits break off and travel around in the blood stream
36
Manganese Deficiency
causes yellow spots and/or enlarged holes between the veins
37
Measles
a viral disease which causes fevers and skin rashes, spread in cough droplets and has no cure, so an infected person must be isolated. May cause brain damage leading to blindness, bowel issues and death
38
Nicotine
an addictive substance found in cigarettes that can cause fatal damage to cells
39
Nitrogen Deficiency
causes upper leaves to turn light green, lower leaves to turn yellow and bottom or older leaves to turn yellow and shriveled, as nitrogen is needed to make amino acids for protease
40
Pathogen
a bacteria, virus or microorganism that can cause disease
41
Phosphate Deficiency
causes leaves to turn darker than normal and causes the plant to lose its leaves
42
Poliomyelitis
a highly infectious viral disease that can affect nerves and cause paralysis
43
Potassium Deficiency
causes yellowing at the tips and edges, often in younger leaves, and causes dark or yellow patches to appear on leaves
44
Proton Beam Therapy
a type of cancer treatment where proton beams are aimed at the tumour
45
Radiotherapy
treatment where high energy radiation is used to shrink tumours and kill cancer cells by destroying their DNA, where the radiation is concentrated on one single place by several low-energy beams being converged on the tumours
46
Risk Factors
factors which make you more susceptible to disease, e.g. age, diet, body weight
47
Rose Black Spot
a plant disease caused by fungi that causes black lesions on the leaves so the leaf doesn't photosynthesise well and dies
48
Salmonella
a communicable disease caused by salmonella bacteria which live in the guts of animals and can be found in raw meat, poultry eggs and egg products, can disrupt natural gut bacteria if the end up in your body, often caused by eating uncooked foods, causes 2.2 million deaths a year
49
STD

bacteria that are resistant to antibiotics, such as MRSA
54
Symptoms
what we can feel, eg a headache
55
Tetanus
a bacterial disease marked by rigidity and spasm of the voluntary muscles
56
TMV
Tobacco Mosaic Virus a plant disease called by viruses that causes yellowing of the leaves, meaning they don't photosynthesise well
57
Type 1 Diabetes
where the pancreas doesn't produce enough insulin
58
Type 2 Diabetes
a lifestyle disease where your cells stop responding to insulin
59
