BIOL:1412 MIDTERM 3 EXAM
QUESTIONS WITH 100% CORRECT
ANSWERS LATEST VERSION 2025/2026.
Parthogenesis - ANS development of an unfertilized egg
regeneration - ANS complete organism formed from fragment
sertoli cells - ANS cells found within the seminiferous tubules that provide metabolic support
for the spermatids
interstitial/leydig cells - ANS produce testosterone into seminiferous tubules
external fertilization - ANS process in which eggs are fertilized outside the female's body,
often in water
hermaphrodites - ANS organisms that contain both female and male sex organs.
reproduction decoupling - ANS time between reproductive steps
semelparity - ANS only reproduce once
1 @COPYRIGHT 2025/2026 ALLRIGHTS RESERVED.
, iteroparity - ANS capable of 2+ periods of reproduction
complete cleavage - ANS cytoplasm completely divided
incomplete cleavage - ANS no complete division, yolk inhibits it
radial cleavage - ANS blastocoel formed, complete cleavage
spiral cleavage - ANS new cells rotated slightly, complete cleavage
mosaic development - ANS Pattern of animal embryonic development in which each
blastomere contributes a specific part of the adult body.
regulative development - ANS A pattern of animal embryonic development in which the fates
of the first blastomeres are not absolutely fixed. loss of cells doesn't affect embryo
epiblast - ANS the outermost layer of an embryo before it differentiates into ectoderm and
mesoderm. gives rise to embryo proper
hypoblast - ANS forms yolk sac
syncytium - ANS nuclei divide without a membrane surrounding each. in insects
sea birds salt excretion method - ANS nostrils
