Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Dolphins use unique sounds to talking travel and mate with each other.To use and understand this communication system The brains of dolphins are bigger than most water animals. This complexity increased to support complex social relations. It could also have been driven by changes in diet, the emergence of echolocation, or an increase in territorial range. Bottlenose dolphins have bigger brains than humans and they have a brain-to-body-weight ratio greater than great apes do . It’s the latest study supporting the idea that big brains evolved to handle the demands of socializing, and not for some other reason.
