Biology

• What type of reproduction does malaria use in a mosquito?

  Sexual
• What type of pathogen causes malaria?

  Protist
• The phloem transports amino acids and sugars
• The phloem transports amino acids and sugars in plants
• What does DNA stand for?

  Deoxyribonucleic acid
• A vasectomy is an example of surgical contraception.
• In the palisade mesophyll tissue, most photosynthesis takes place.
• Lymphocytes (a type of white blood cell) are produced when a mouse is injected with an antigen.
• In genetic engineering, enzymes isolate the gene, and it is transferred to a plasmid or virus to act as a vector to an organism.
• Plants make amino acids fom the nitrates they absorb.
• Lamarck's theory of evolution was discredited as it didn't have a genetic basis.
• In green plant cells, the cell wall is made of the carbohydrate cellulose.
• Phagocytosis is when white blood cells engulf bacteria and other pathogens
• Lymphocytes are combined with a particular kind of tumour cell to make a cell called a hybridoma cell.
• A disadvantage of using monoclonal antibodies as treatment is that they create side effects.
• Soluble substances can move into or out of cells by diffusion
• What type of organism is Penicillium?


  Fungi
• Bacteria reproduce using binary fission
• Some plant cells contain oil droplets which store glucose.
• A plant's growth is stunted. Which mineral ion is it lacking?


  Nitrate ions
• At a synapse, neurotransmitters are released by one neurone to cause an impulse in another.
• Epidermal tissue is found covering the surface of leaves.
• Efficacy describes how well a drug cures an illness or improves symptoms.
• Nitrates allow plants to make proteins
• Translocation moves sugars around the plant
• Cellular differentiation is when cells specialise in an organism.
• Statins are prescribed drugs that lower cholesterol in the blood.
• Tissue - a group of cells that possess a similar structure and perform a specific function
• Give an example it a strain of bacteria that has developed antibiotic resistance

  MRSA
• Meiosis only occurs in the sexual organs
• Carl Richard Worse developed the three domain system of classification
• The three adaptations organisms have can be categorised into structural, behavioural and functional (physiological).
• Predator prey cycles are the cyclical increase and decrease of predator and prey populations over time.
• Carl Worse created the three domain classification system: archaea, bacteria and eukaryta
• Ribosomes synthesise proteins
• Lymphocytes are produced when a mouse in injected with antigens
• Blood flowing through the muscles transports lactic acid to the liver where it is converted back into glucose.
• Protease is also called pepsin
• Enzymes work best for humans at 37°C
• Plant enzymes work at 6 - 10°C
