2.4 Metabolism In Conformers and Regulators

Question 1

What are abiotic factors?

Answer 1

Abiotic factors include temperature salinity and pH

Question 2

How do conformers adapt to environmental changes?

Answer 2

Behavioural responses by conformers allow them to tolerate variation in their external environment to maintain optimum metabolic rate

Question 3

What is the hypothalamus?

Answer 3

The hypothalamus is the temperature monitoring centre

Question 4

How is information communicated through the body?

Answer 4

Information is communicated by electrical impulses through nerves to the effectors which bring about a corrective response to return temperature to normal

Question 5

Sweating

Answer 5

Body heat is used to evaporate water in sweat, cooling the skin

Question 6

Vasodilation

Answer 6

Increased blood flow to skin increases heat loss

Question 7

Decreased metabolic rate

Answer 7

Less heat is produced

Question 8

Shivering

Answer 8

Muscle contraction generates heat

Question 9

Hair erector muscles contract

Answer 9

Traps layer of insulating air

Question 10

Increased metabolic rate

Answer 10

More heat is produced

Question 11

Vasoconstriction

Answer 11

Decreased blood flow to the skin decreased heat loss
