AQA GCSE Biology topic 5 - Homeostasis and Response Exam Practice Questions and Answers 100% Correct homeostasis - Answer️️ -maintaining a stable environment e.g. nervous and hormonal communications, body temp, blood glucose levels. negative feedback - Answer️️ -A process that counteracts a change - increasing and decreasing levels to maintain homeostasis, e.g. sweating to lower the body temp the nervous system - Answer️️ -A system that manages the body through negative feedb...

Suggest the advantages of the change in blood flow in blood vessels during exercise. [3 marks] - answer--more blood flow to muscles during exercise -supplying more glucose and oxygen/ removing carbon dioxide/ lactic acid/ heat -for high rate of respiration/ to meet increased demand for energy Explain how microorganisms contributed to the increase in temperature during processing of organic waste. [2 marks] - answer-respiration produces heat explain the advantage of showing the data using...

All sample questions with matching correct answer in chapter 5 negative tropisms - Answer-growth away from a stimulus Define homeostasis - Answer-Homeostasis is the regulation of internal conditions in the body. It is necessary to maintain optimal conditions for body functioning. These internal conditions can change as a result of processes within the body and as external conditions change. systems responsible for homeostasis - Answer-the nervous system - uses electrical impulses ...
