gjynah qe nuk pati fat ne fund. por ahahahah sa kam qeshur me ate shfaqjen e kung fu-se, gurax. video fantastike :D

ndersa kur pashe kete videon poshte me erdhi vertet shume keq. natyra funksionon sipas ligjit te me te fortit (fizikisht ose menderisht), por nganjehere eshte kaq e pameshirshme sa eshte edhe e bukur. pinguinet dihet qe jane specie monogame, tere jeten e kalojne me te njejtin partner. ne kete video tregon per shfaqjen e tradhetise ne nje cift pinguinesh. femra ciftohet me nje mashkull tjeter, te dy meshkujt luftojne deri ne gjakosje per te fituar femren, dhe ne fund femra zgjedh me te fortin. vuajtjet e pinguinit humbes ta kepusin shpirtin. :(

Ishte nje pyetje per...............1 MILION EURO.Pjesmarresi qe ishte BRILIANT dha pergjigjen e gabuar(me erdhi keq).
Pyetja ishte....cilat nga keto kafshe jane helmuese.

une e dija sepse kisha lexuar nje TJETER.

A classic example of evolution... One day, a male rodent got sick and tired of watching its brothers and sisters being devoured by snakes. It stopped eating nuts and started hunting for insects and smaller rodents. Being bigger and badder than other males, it had more chances to mate with every female it could. Its offsprings carried their father's physical advantage and fierce mental disposition which then was passed on to its offsprings. This process repeated for thousands if not millions of years. End Product? Mongoose, a lethal predator that is pound for pound more dangerous than a lion or tiger, that is specifically designed to hunt snakes. kudos to that first rodent who stepped up his game in the food chain.

Mermithids (phylum Nematoda) and hairworms (phylum Nematomorpha) somehow drive their arthropod hosts into water, which is essential for the worms' survival after egression. The mechanisms behind this behavioural change have been investigated in hairworms, but not in mermithids. Establishing a similar mechanistic basis for host behavioural change between these two distantly related parasitic groups would provide strong convergent evidence for adaptive manipulation and insight into how these parasites modify and/or create behaviour. Here, we search for this convergence, and also contrast changes in physiology between hosts infected with immature and mature mermithids to provide the first ontogenetic evidence for adaptive manipulation by disentangling host response and pathology from the parasite's apparent manipulative effects. We used SWATH-mass spectrometry on brains of Forficula auricularia (earwig) and Bellorchestia quoyana (sandhopper), infected with the mermithids Mermis nigrescens and Thaumamermis zealandica, respectively, at both immature and mature stages of infection, to quantify proteomic changes resulting from mermithid infection. Across both hosts (and hairworm-infected hosts, from earlier studies), the general function of dysregulated proteins was conserved. Proteins involved in energy generation/mobilization were dysregulated, corroborating reports of erratic/hyperactive behaviour in infected hosts. Dysregulated proteins involved in axon/dendrite and synapse modulation were also common to all hosts, suggesting neuronal manipulation is involved in inducing positive hydrotaxis. Furthermore, downregulation of CamKII and associated proteins suggest manipulation of memory also contributes to the behavioural shift.
