It used to be thought that the dog-like marsupials of Australasia, the thylacines, were close kin of borhyaenoids, but anatomical and molecular data shows that this is not the case: thylacines are part of the exclusively Australasian marsupial clade that includes the dasyures.
Having the right body temperature is an essential feature of good health. A low body temperature indicates that you may be unwell and have some health problem. Low body temperature can cause you a number of problems such as fatigue, depression, anxiety and panic attacks, cold intolerance, insomnia, constipation, and more. 98.6 Â°F or 37 Â°C is considered to be normal body temperature. It could however vary between 97.5 Â°F to 98.8 Â°F (36.4 Â°C to 37.1 Â°C) for most individuals.
Cold is the presence of low temperature, especially in the atmosphere. In common usage, cold is often a subjective perception. A lower bound to temperature is absolute zero, defined as 0.00 K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to â273.15 Â°C on the Celsius scale, â459.67 Â°F on the Fahrenheit scale, and 0.00 Â°R on the Rankine scale.
