AQA A-level BIOLOGY (7402/1) Paper 1 MARKING SCHEME QUESTIONS AND ANSWERS 2024 SPECIMEN VI Question 1: (a) Describe what is meant by the term 'metabolic rate'. [2] (b) Explain how the control of body temperature is an example of homeostasis. [4] Answer 1: (a) 'Metabolic rate' refers to the rate at which chemical reactions occur within an organism's cells. It's a measure of the amount of energy expended by an organism per unit of time. (b) The control of body temperature is ...

PCA: Weeds Latest Version Already Passed Dicot have two seed leaves inside the seed coat. They are usually rounded and fat, because they contain the endosperm to feed the embryo plant Monocot An angiosperm that has only one seed leaf. reproductive capability of weeds weeds often form persistent seedbanks and can reproduce at a young age. rhizomes or other vegetative structures, these plants can form thick, single-species stands. Describe the mechanisms by which weed seeds are d...

explain the rule of phosphoglucomutase in glucose catabolism - it can transform G1P -> G6P during energy investment phase of glycolysis. It can also turn G6P -> G1P to begin the glycogenesis pathway glucose catabolism - if energy needs are met in the cell, G6P is converted to G1P catalyzed by phosphoglucomutase which triggers glycogenesis glycogenesis - the pathway that synthesizes glycogen as a result of excess glucose glycolysis - pathway that turns glucose to pyruvate for use in c...
