How can an alteration in chromosome number or structure impact a living organism? Why genes are important in planaria regeneration? Describe one evolutionary adaptation of the live protist species Spirostomum and be sure to explain how the trait increases survival / reproduction. How does biolog...
Island faunas can be characterized by gigantism in small animals and dwarfism in large animals, but the extent to which this so-called ‘island rule’ provides a general explanation for evolutionary trajectories on islands remains contentious. Here we us
Variations in the Body Structure of Carabids in Adaptation to Environment and Mode of LifeCarabids belong to the suborder Adephaga of the order Coleoptera. As compared with the 200 families comprising the other suborder, the Polyphaga, the Adephaga as a group are poor with respect to......
Animals exhibiting mirror self-recognition (MSR) are considered self-aware; however, studies on their level of self-awareness remain inconclusive. Recent research has indicated the potential for cleaner fish (Labroides dimidiatus) to possess a sophisticated level of private self-awareness. However, as...
of body patterns and the associated components expressed during social interactions of the diurnal reef-dwelling species,Abdopus capricornicus. This is the first study aimed at disentangling the body patterns used for camouflage from those used for communication. This was achieved by staging ...
The structure of the normal lungs Neuroendocrine cells Neuroendocrine cells, which are also known as Kultschitsky-type cells, Feyrter cells andAPUD cells, are found in the basal layer of thesurfaceepithelium and in the bronchial glands.75,76In the surface epithelium they occur singly and in gr...
In the native state, the structure forms a homotrimer. The S1 subunit harbours a rigid N-terminal domain (NTD) and a receptor-binding domain (RBD) responsible for receptor attachment. On the other hand, the S2 sub-unit is known for host cell membrane fusion and thus comprises a fusion ...
Ballistic hardness is measured in GPa; Kevlar, with 80 GPa, outperforms pure steel at 200 GPa. Its unique chain-like structure imparts a tensile strength of 3.5 GPa, surpassing steel’s 1.5 GPa, enhancing flexibility. Besides ballistic vests and plates, Kevlar finds utility in helmets and kay...
