A water temperature of 10 °C (50 °F) can lead to death in as little as one hour, and water temperatures near freezing can cause death in as little as 15 minutes. [37] During the sinking of the Titanic , most people who entered the −2 °C (28 °F) water died in 15–30 minutes.
Water can be used to cook foods such as noodles. Sterile water for injection. Boiling, steaming, and simmering are popular cooking methods that often require immersing food in water or its gaseous state, steam. [154] Water is also used for dishwashing. Water also plays many critical roles within the field of food science.
These dietary changes may also have altered human biology; the spread of dairy farming provided a new and rich source of food, leading to the evolution of the ability to digest lactose in some adults. [235] [236] The types of food consumed, and how they are prepared, have varied widely by time, location, and culture. [237] [238]
The energy used by human cells in an adult requires the hydrolysis of 100 to 150 mol/L of ATP daily, which means a human will typically use their body weight worth of ATP over the course of the day. [30] Each equivalent of ATP is recycled 1000–1500 times during a single day (150 / 0.1 = 1500), [29] at approximately 9×10 20 molecules/s. [29]
The spores require warm temperatures, a protein source, an anaerobic environment, and moisture in order to become active and produce toxin. In the wild, decomposing vegetation and invertebrates combined with warm temperatures can provide ideal conditions for the botulism bacteria to activate and produce toxin that may affect feeding birds and ...
The dry-season forms are usually more cryptic, perhaps offering better camouflage when vegetation is scarce. Dark colours in wet-season forms may help to absorb solar radiation. [99] [100] [94] Butterflies without defences such as toxins or mimicry protect themselves through a flight that is more bumpy and unpredictable than in other species.
Bacteria grow to a fixed size and then reproduce through binary fission, a form of asexual reproduction. [116] Under optimal conditions, bacteria can grow and divide extremely rapidly, and some bacterial populations can double as quickly as every 17 minutes. [117] In cell division, two identical clone daughter cells are produced. Some bacteria ...
At the time of the first British arrival, Darjeeling was known among its Lepcha inhabitants as Dorje-ling, or the "Place of the Thunderbolt." [g] According to the Oxford Concise Dictionary of World Place Names, Darjeeling is derived from the Tibetan Dorje ling or Dorje-glin, meaning "Land of Dorje," i.e. of the vajra, the weapon of the Hindu god Indra.
