Glycerate Triose( Glycerate, Triose ) Phosphate is converted to triose glycerate( triose, glycerate ) phosphate as 1 2( 1, 2 ) ATP is converted to ADP +Pi and 1 NADPH is converted to NADP (reducing oxidising( reducing, oxidising ) the GP)

Complete these statements about intensive farming:
-> Economically beneficial harmful( beneficial, harmful )
-> Less More( Less, More ) waste
-> Reduces Increases( Reduces, Increases ) biodiversity
-> Increases Decreases( Increases, Decreases ) productivity
-> Takes nutrients out of soil

The products of glycolysis are:
2 3 1( 2, 3, 1 ) ATP
2 3 1( 2, 3, 1 ) reduced NAD
2 3 1( 2, 3, 1 ) pyruvate

As pressure is applied to the Pacinian corpuscle, the shape of the membrane changes and stretch mediated sodium potassium calcium( sodium, potassium, calcium ) ion channels are opened and sodium potassium calcium( sodium, potassium, calcium ) ions to flood in.

Heart rate is controlled by the autonomic sensory central( autonomic, sensory, central ) nervous system. The sympathetic parasympathetic( sympathetic, parasympathetic ) nervous system speeds up the heart rate and the parasympathetic sympathetic( parasympathetic, sympathetic ) slows it down. Changes are controlled by the medulla oblongata in the brain heart pancreas( brain, heart, pancreas ). Changes occur due to chemical (by chemoreceptors baroreceptors( chemoreceptors, baroreceptors )) and pressure changes (by baroreceptors chemoreceptors( baroreceptors, chemoreceptors ))

-> No Lots of( No, Lots of ) immigration
-> No Many( No, Many ) mutations
-> Random Selective( Random, Selective ) mating

Place the following statements about how the gene machine works in the correct order:
2 1 3( 2, 1, 3 )) Nucleotides are added step by step in the correct order
1 2 3( 1, 2, 3 )) Sequence is designed
3 1 2( 3, 1, 2 )) Short sections of DNA called oligonulceotides are produced and joined together into longer DNA fragments
