On successful completion of this course, you should be able to:

1. identify the roles of the major physiological systems in diverse animals and how they are regulated through electrical and chemical signals to achieve change or maintain homeostasis
2. explain the role of nerves, muscles and cell signalling pathways, and how they contribute to control of physiological processes
3. articulate the role of physiological systems and processes in disease and dysfunction
4. compare the nature of interactions between organisms at the level of the population, the community and the ecosystem
5. discuss the mechanisms by which evolution generates biological diversity, and how this is important for ecosystem health

Question 1
In contrast to passive transport, all forms of active transport require ATP as a source of energy.

• True CDFalse
  
• Question 2
  Quechua natives have barrel chests as an adaptation to living at high altitude for generations. If a Quechua woman conceived a child at high altitude but all of the embryonic development and childhood occurred at sea level, the child would not be expected to develop a barrel chest as they got older.

• Question 3
  The stomach has deep pits on the surface to increase the rates of absorption of carbohydrates, such as glucose.
  0 True 0 False
  
• Question 4
  The trachea in insects are like those in humans. They bring air from the mouth to the site of gas exchange.
  CDTrue C) False

Question 5

Epithelial tissues are normally found lining the inner surface of organs, such as adrenal glands and heart.

CDTrue C) False

Question 6

The myenteric plexus is a collection of nerves that exists within the hypothalamus that controls circular and longitudinal muscles of the GI tract.

CDTrue C) False

Question 7

The simplest of animals possesses a closed circulatory system.

CDTrue 0 False

Question 8

The four main elements of the central nervous system are the afferent division, the somatic system, the parasympathetic and sympathetic division.

0 True 0 False

Question 38
Cayenne peppers taste hot because they bind to thermoreceptors and cause local heating.
0 True 0 False
Question 39

Question 60
The first line of defense against an external pathogen is a robust adaptive immune system.
0 True C) False
Question 61
Ectotherms regulate a combination of heat production and heat loss to ensure that their body temperature remains within a narrow range.
0 True () False
Question 62
Juvenile hormone and estradiol are the main two hormones that control insect growth and development, usually acting in reciprocal ways on processes and signaling pathways.
0 True 0 False
Question 63
