Animals obtain energy mostly through - ANSWER-The oxidation of foodstuffs - metabolism : the consumption and then burning of energy What do animals feed on and how? - ANSWER-- small particles (endocytosis, filtering) - large masses (breakdown by mastication) - liquid = nectar, blood, milk - symbiosis Kingfisher, Tody Tyrant, and Grosbeak are all examples of - ANSWER-Birds that have adapted different beak sizes to maximize their ability to collect food - Kingfisher = long beak, speci...

All of the above Digestive physiology is concerned with: A. The sensory system employed to locate food B. The mechanical disruption of food C. The chemical conversion of food molecules into transportable forms D. All of these Joules Which of the following is the standard unit of measurement that describes the energy of dietary items?

Membrane depolarization above threshold opens voltage-gated sodium channels and produces an action potential. However, the initial depolarization opens only a few sodium channels. The sodium channels open, which depolarizes the membrane, which opens more sodium channels, which depolarizes the membrane further, which opens more sodium channels; and so it goes as the membrane eventually becomes positive. This opening of sodium channels is an example of: a) none b) positive feedback c) feed fo...

Regulators - ANSWER-keep a physiological parameter constant despite fluctuations in the environment Regulators (graph) - ANSWER- Conformers - ANSWER-allow a physiological parameter to fluctuate with the environment Conformers (graph) - ANSWER- Homeostasis - ANSWER-Maintaining a stable condition (regulators) - regulation of internal environment - external environment can be highly variable - within a range rather than fixed 2 methods homeostasis can be regulated - ANSWER-1. Intr...

What are the 2 fluid compartments of the body? What 2 sub-types of the second compartment is there? - ANSWER-1. intracellular fluids 2. extracellular fluids (interstitial fluid, blood plasma) Describe the composition of body fluid (3). (point 2 has 3 sub-points) - ANSWER-- water - large molecules -> carbohydrates: sugars -> proteins: enzymes -> fats: fatty acids - electrolytes: inorganic ions and salts What are the 3 types of regulation of blood plasma? - ANSWER-- osmotic re...

What is an animal? Multicellular euakaryotes, heterotrophic (obtain energy from energy-releasing food substances), that generally reproduce sexually, capable of motion at some point in their lives and can respond quickly to external stimuli Animals are structurally dynamic that.... - That need atoms of bodies in dynamic exchange with the environment. - Molecular constituents are broken down and rebuilt - Adults typically resynthesise 2%-3% of their body proteins each day What do anim...

Define behavior - ANSWER-any internally coordinated response of whole living organisms to internal and/or external stimuli, excluding responses more easily understood as developmental changes such as arthritis proximate causes of behavior - ANSWER-HOW genetic, cellular, physiological, and anatomical mechanisms underlie an animal's ability to detect and respond to stimuli. ultimate causes of behavior - ANSWER-evolutionary adaptations and selection pressures. WHY did the behavior evolve. Na...
