Answer 1

suggests that animals with greater biological fitness, signal this status through handicapping behavior

Question 2

Injections with Cholecystokinin (CCK) _______ increases feeding behavior

Answer 2

ntagonistsa.

Please note that Cholecystokinin (CCK) is a hormone that helps in the digestion of fats and proteins in the small intestine. It is known to suppress (подавляет) hunger, so injections with CCK would typically decrease feeding behavior rather than increase it.

Question 3

________ helps store glucose as glycogen and assists in moving glucose from the blood supply into body cells (помогает накапливать глюкозу в виде гликогена и способствует перемещению глюкозы из кровотока в клетки организма)

Answer 3

insulin

Question 4

_________ is released (высвобождается) primarily during stages 3 and 4 of NREM sleep

Answer 4

growth hormone

Question 5

K complexes begin to appear in stage __________ of SWS

Answer 5

Stage 2

K complexes, which are large amplitude patterns of brain activity (представляющие собой паттерны мозговой активности большой амплитуды) that can be visualized on an electroencephalogram (EEG), begin to appear in stage 2 of Non-Rapid Eye Movement (NREM) sleep, also known as Slow-Wave Sleep (SWS) - медленноволновой сон. Stage 2 is characterized by sleep spindles (сонных веретен) and K complexes, both thought to play a role in memory consolidation and protection of the brain from awakening from sleep.
