Carnivorous mammal with a supple muscular body and paws ending in retractable claws; it is a very common pet. morphology of a cat retracted claw extended claw cat’s headcat breeds There are more than 30 officially recognized breeds of domestic cat, classified into three groups according to ...
Thus, our study provides key information on the role of reservoirs (Nasua narica and Procyon lotor) in the transmission and maintenance of T. cruzi in Mexico. This is complemented with the follow up of infection which took place for a relatively long period (five years). In this sense, ...
Therefore, before sexual behavior per se can be initiated, physical contact with a partner must be established. This is normally achieved by displaying behaviors leading to reduced physical distance to a potential partner, eventually ending in physical contact and copulation. In fact, behaviors ...
as we mention. Crucially, telomeric proteins actively engage with telomeric DNA, facilitating its folding and ensuring its functionality. These specialized proteins effectively create a protective barrier around telomeres
Arrows represent the direction of the muscle forces (the lengths do not reflect the magnitude of the force vectors), with SM and MP vectors ending at the expected muscle origins but the TM vector is truncated. For simplicity, the TM vector (purple arrow) and coronoid process elevation are ...
of slow fibers, and likely do not function in locomotion. In soaring birds, muscles with slow fibers also function isometrically and maintain the outstretched wing for extended lengths of time. Thus birds and mammals have evolved different strategies to deal with their forelimb postures and have ...
One means of pushing the biological information window back beyond the modern day is with data and records from oceanographic, archeological and anthropological studies. Similarly, insights into the functioning of the North Pacific ecosystem and the evolutionary adaptability of marine mammals to ecosystem...

Instead, it is clear that the largest whaling effort—starting in 1788 and apparently ending in 1877 (with perhaps a few sporadic attempts into the twentieth century)—was on sperm whales, with occasional takes of so-called finbacks (Balaenoptera sp.), so-called porpoises (small delphinids),...
Starting from the first TRGV11 gene at its 5 end, and ending with TRGC2 gene at its 3 end, it spans about 105 kb and, similarly to each of the two TRG loci in sheep, it is organized into three V-J-J-C cassettes [97]. The distance between the STARD3NL gene...
