Although ice crystals form under the skin when frogs hibernate in the winter, a high concentration ofglucose occurring naturally in the frog's organs prevents the animal from freezing. Even when a deep freeze causes the frog's heart to stop beating and the frog to stop breathing, the body w...
I would say “is not dissimilar to”. I did this all the time. One of the best things Dave Martill (my supervisor) did for me was to red-
And my reply (which I did send to Liam the next day, but am only now getting around to posting here): I never set out to do a Ph.D really. I just wanted an institutional affiliation so I could access online resources via the library, and it turns out that universities won’t (or...

Why did animals evolve to breathe air? How does water move between the hydrosphere and atmosphere? How can upwelling affect the thermocline's depth in a body of water? Describe what happens when you add water to a graduated cylinder and relate this phenomeno...
Last week CTV News did a segment with a Canadian doctor named Mike Evans, who started a Twitter campaign to encourage people to take the stairs, park farther away, sit less, and walk more. There’s nothing groundbreaking about this advice. Telling […]
Nepal to be highly endemic region for HPAI despite Her geography.One study found H9N2 in the stool of a ruddy shelduck (Tadorna ferruginea) in seven wetland migratory bird roosting areas (Karmacharya et al.2015). This suggested that this strain leads to endemicity in poultry and may evolve...
Juvenile African clawed frogs, Xenopus laevis, were exposed to commercial formulations of THX and CLO at high (100 ppm) and low (20 ppm) concentrations of the active ingredient. Mortality, growth, development, liver metabolic enzyme activity, and gene expression endpoints were quantified. Tadpoles ...
