One primary factor in shaping the polarity of the body axes in chick embryos is C. gravity.
The early developmental stages for organisms are a complex procedure and each kind of organism has its own kind of developmental phase. In mammals, the size of an egg is particularly small, hence the study becomes more difficult.
Gravity acts as a critical factor for determining the body axis at the time of embryogenesis. The dorsal-ventral axis for chick embryos is fixated due to gravity.
The bilateral symmetry of a chick depends on gravity. Research has shown that intrauterine rotation is only a tiny factor in shaping the bilateral symmetry of a chick embryo. It is the gravity that mostly affects the bilateral symmetry.

Answer:
C ender is released
Explanation:
the energy stored in the phosphate bonds hold the energy, when the bond breaks the energy stored is released
Answer:
If the enamel or cementum gets worn down or if the gum line has receded, then the dentin becomes exposed. "Cavities, cracked teeth, gum recession, enamel and root erosion all cause dentin to be exposed," Culotta-Norton said. "Dentin is connected to the nerve that triggers pain in sensitive teeth."
Answer:
clear example of homologous structures is the forelimb of mammals. When examined closely, the forelimbs of humans, whales, dogs, and bats all are very similar in structure. Each possesses the same number of bones, arranged in almost the same way. ... They are analogous structures.
