that several means are equal.
|||||| |||||| |||||| ||||||




2 way ANOVA - correct answer ✔analysis of variance for 1 dependent variable by
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




one or more factors and/or variable
|||||| |||||| |||||| |||||| ||||||




Scope for growth - correct answer ✔Measure of excess energy beyond that needed
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




for maintenance
||||||




maintenance metabolic cost is influenced by - correct answer ✔Temp, salinity,
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




oxygen, light ||||||




Response sequence order - correct answer ✔1. Environmental change
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




2. Receptors - antennae, tentacles
|||||| |||||| |||||| ||||||




3. Transfer system- nervous connections to muscle system, endocrine system
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




4. Response to environmental change maximizes fitness
|||||| |||||| |||||| |||||| |||||| ||||||




Types of adaptive responses - correct answer ✔Behavioral
|||||| |||||| |||||| |||||| |||||| |||||| ||||||




Physiological ||||||




Biochemical ||||||




Gene regulation ||||||




Acclimation - correct answer ✔response followed by new equilibrium
|||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||

, Regulation - correct answer ✔maintain homeostasis despite change
|||||| |||||| |||||| |||||| |||||| |||||| ||||||




Conformance - correct answer ✔internal state changes to match external|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




environmental change no |||||| ||||||

Osmosis - correct answer ✔movement of water across a membrane
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




osmotic pressure - correct answer ✔Created when solute differs on either side, thus
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




water moves in dirrection of higher solute concentration
|||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




Diffusion - correct answer ✔Random movement of dissolved substances across a

membrane tends to equalize concentration |||||| |||||| |||||| ||||||




ion regulation - correct answer ✔A response to salinity, done best by crustacea due
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




to isolation of body (hard bodies) but poorly by soft body species
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




Osmolytes - correct answer ✔Organic substitute for inorganic ions - allows regulation
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




of cell volume and maintenance of inorganic ion concentrations , very expensive
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||
