This British grass snake exhibits dicephalus, a condition related to conjoined twinning. It is caused during development by high incubation temperatures.
The characterization of photobiological hydrogen production for four marine green algae by sulfur-deprived and treated with uncoupler after dark anaerobic incubation was investigated.
Amino-PVA-SPION alone was detectable in cytoplasmic endosome-like structures after 3 hours of incubation but resulted in early cell death after 24 hours.
The Parental Care Model hypothesizes that endothermy is arisen as a consequence of selection for parental care because endothermy enables a parent to control incubation temperature.
