BIOL 117 EXAM 4 HIGH-YIELD PHYSIOLOGY
AND ORGANISMAL BIOLOGY SUMMARY 2026
◉ [x]gap genes, [y]pair rule genes, and [z]segment polarity genes.
Answer: After morphogen genes are activated during animal
embryonic development, the next three gene classes in the genetic
regulatory cascade are, in order: [x], [y], and [z]
◉ gastrulation.
Answer: 1 out of 1 points
At which developmental stage should one be able to first distinguish
a diploblastic embryo from a triploblastic embryo?
◉ are distributed unequally amongst daughter cells
affect cell differentiation.
Answer: Cytoplasmic determinants...select all that apply.
◉ notochord
nueral tube
ectoderm
mesoderm.
,Answer: Somites receive morphogen signals from which of the
following sources? Multiple answers can be selected.
◉ cell differentiation.
Answer: The separation of gastrula cells into endoderm, ectoderm,
and mesoderm is part of which developmental step?
◉ gap genes, pair rule genes, and segment polarity genes.
Answer: After morphogen genes are activated during animal
embryonic development, the next three gene classes in the genetic
regulatory cascade are, in order: [x], [y], and [z]
◉ keeps a constant body temperature
can produce its own heat.
Answer: If an animal can be described as both an endoderm and a
homeotherm, then this animal.... Multiple answers can be selected
