Atividade da tripsina em rã-touro na fase pós-metamórfica Trypsin activity of the bullfrog in the post-metamorphic phase

Revista Brasileira de Zootecnia, 2004
Com o objetivo de avaliar a atividade enzimática da tripsina no conteúdo intestinal da rã-touro (Rana catesbeiana Shaw, 1802), 320 animais com peso médio de 3,6 g foram distribuídos em baias-teste com temperatura e fotoperíodo controlados.

Tuning in the bullfrog ear

Biophysical Journal, 1988
When electrical resonances were observed in acoustic sensory cells of lower vertebrates, the hearing research community was presented with the exciting possibility that tuning in the ears of those animals might be explained directly in terms of familiar molecular devices.

Making Learning Personally Relevant: Sensemaking Assets Used in Families' Discussions While Using a Pollinator‐Focused Mobile Augmented Reality App

Science Education, Volume 110, Issue 2, Page 525-542, March 2026.
ABSTRACT This study seeks to better understand the unique sensemaking assets that rural families weave into their outdoor learning experience while using a location‐based mobile app focused on healthy habitats for solitary bees. The project included mobile augmented reality (AR) technologies, which are increasingly used as educational tools at informal

Timing of detachment faulting in the Bullfrog Hills and Bare Mountain area, southwest Nevada: Inferences from 40Ar/39Ar, K-Ar, U-Pb and fission track thermochronology [PDF]

, 1997
Crustal extension in the Bullfrog Hills and Bare Mountain area of southwest Nevada is associated with movement along a regional detachment fault. Normal faulting in the upper plate and rapid cooling (denudation) of the lower plate were coeval with ...

Characterization of the toll‐like receptor 13 homologs in American bullfrogs, Lithobates catesbeianus, and their involvement in antimicrobial immunity

Journal of the World Aquaculture Society
Toll‐like receptors (TLRs) are an important family of pattern‐recognition receptors that recognize a series of pathogen‐associated molecular patterns to trigger the host immune response.
