B) natural selection select that territorial behavior that is benefit is greater than cost
C) Imprinting, a form of learning in which a very young animal fixes its attention on the first object with which it has visual, auditory, or tactile experience

#Unit 2. Cellular Organization
The polymerization of pure G-actin in vitro proceeds in three phases.
|
Column I |
Column II |
|
A. nucleation phase |
i. G-actin monomers exchange with subunits at the filament ends, but there is no net change in the total length of filaments |
|
B. elongation phase |
ii. marked by a lag period in which G-actin subunits combine into an oligomer of two or three subunits |
|
C. steady-state phase |
iii. the short oligomer rapidly increases in length by the addition of actin monomers to both of its ends |
