1:31 - three factors we need to keep constant (blood glucose levels, water levels, temperature) 4:11 - path of the nervous system (a neuron is an individual nerve cell) a relay neuron, just like in a relay race, passes impulses between different neurons. 5:48 - a gap between two neurons is known as a synapse. 5:52- neurotransmitters (chemical messengers) diffuse from one synapse to the receptors on the next neuron which causes an electrical impulse to be triggered. 6:56 - reflex arc does not involve conscience parts of the brain. most sensory neurons do not pass directly into the brain, but synapse in the spinal cord 9:59 - thyroxine controls development in children, adrenaline increases o2 and glucose levels. 11:23 - the brain releases TSH which controls how much thyroxine the thyroid gland produces. if there is too much thryoxine in the blood then less TSH is produced. 12:06 - too much glucose can damage organs such as eyes and kidneys. insulin is produced when there is too much glucose so that organs can use the glucose for respiration. if there is still excess glucose it is stored as glycogen which is stored in the liver and the muscles. 13:50 - if there is little glucose then the pancreas detects it and releases glucagon which alerts the liver and muscles so that they can turn the glycogen back into glucose. 14:28 - GLUCAGON= GLUCOSE GONE (released when glucose is low!) 17:57- label the female thing 18:40 - FSH= ovulation (causes a egg to mature every 28 days) LH = stimulates the release of mature egg Progesterone and Oestrogen= maintain the lining of the uterus so that it is ready for a fertilised egg. 20:49 - idk what this is 22:11- contraception 26:17 - IVF treatment 28:54 - meiosis- a process that takes place in the reproductive system, which halves the number of chromosomes making gametes. meiosis is the same as mitosis, except it has a second division which halves the number of chromosomes. 32:44 - genome screening benefits 34:06 - allele- variations of genes - genotype= the alleles that an organism has inside it 44:38 - polydactyly= caused by a dominant allele, cystic fibrosis= caused by two recessive alleles. people with cystic fibrosis have thick and sticky mucus that the cilia cant push out. this makes a mucus plug and blocks airways and traps bacteria (mucus traps the bacteria) 47:42 - genetic screening 55:16 - stages of natural selection, Speciation: when a changes so much it becomes a different species 1:00:03- genetically engineering for insulin 1:01:56 - how fossils are formed 1:06:54 - evolutionary trees 1:11:51- ecosystem= communities interacting with each other and the non living. 1:19:55 - examples of extreme conditions that extremophiles live in 1:26:43 - water, decay and carbon cycles Detritus feeders feed on dead bodies and waste. They respire and return carbon dioxide to the air. 1:30:08 - fairly constant population size 1:31:33 - how humans reduce biodiversity 1:33:40 - 3 types of pollution LAW LAND AIR WATER 1:34:18 - deforestation and peat bog destruction 1:37:24 - difference between climate change and global warming 1:41:46 - maintaining biodiversity mnemonics
