BIOL 205 - Comparative Invertebrate Zoology midterm 2 review (midterm exam tips) University of British Columbia, Okanagan Campus

Basics of diffusion, gradients, and how they relate - Answer-Diffusion: spontaneous movement of very small things. It requires no energy investment by the organism (other than keeping the temperature above freezing) --direction is random Gradients: top of gradient = high concentration, bottom of gradient = low concentration --diffuses high to low Basics of diffusion across a semipermeable barrier - AnswerFactors that speed up or slow down diffusion - Answer-size: smaller things diffuse fas...

seminiferous tubules - Answer-The testes contain ____ ____ sperm are produced The Juxtaglomerular Apparatus is a(n) ___ composed of macula densa which are specialized epithelial cells in the Distal Convoluted Tubule (DCT) - Answer-Endocrine structure If decreased blood pressure is sensed by the Juxtaglomerular (JG) cells, the JG cells release the hormone renin, which activates angiotensin (also hormone). Angiotensin causes vasoconstriction and secretion of aldosterone (mineralocorticoid hor...
