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...

Bioengernetics - Answer-How energy flows through organisms. ATP - Answer-Used for mechanical, transport, and chemical work. ATP is also an RNA nucleotide. Mechanical Work - Answer-Energy used in motor proteins and muscle cells during contractions. Transport Work - Answer-Energy used to move substances against their gradient. Chemical Work - Answer-Energy used to convey polymers into monomers. Gibs Free Energy - Answer-Portion of a systems energy that can preform work when temperature and p...

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...

Photosynthesis reaction 6CO2 + 6H2O + light energy --> C6H12O6 + 6O2 Carbon dioxide + water + light ----> glucose (sugar) + oxygen Oxygen comes from water Structure of a chloroplast organelle for photosynthesis Has double membrane Contains discs called thylakoids Thylakoids contain chlorophyll Stack of thylakoids called granum Thylakoids surrounded by a fluid called stroma The space inside a thylakoid is its lumen Photons and light pigments in the chloroplasts absorb light Photons can...

A virus has been discovered. The virus has no envelope and consists of a helical capsid surrounding its dsDNA genome. During assembly, the pac site of the genome ensures that it is properly packaged by the capsomeres. Which of the following amino acids is/are expected to be on the capsomere domain that interacts with the pac site? A. lysine B. methionine C. glycine D. arginine E. A and D Answer: A and D Explanation: DNA has a negative charge, so positively charged amino acids, such as...
