Science tourism is a travel topic grouping scientific attractions. It covers interests in visiting and exploring scientific landmarks, including museums, laboratories, observatories and universities. [1] [2] It also includes visits to see events of scientific interest, such as solar eclipses.
Biology is the scientific study of life. [1] [2] [3] It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. [1] [2] [3] For instance, all organisms are composed of at least one cell that processes hereditary information encoded in genes, which
The last of the non-avian dinosaurs died 66 million years ago in the course of the Cretaceous–Paleogene extinction event, whereas the earliest members of the genus Homo (humans) evolved between 2.3 and 2.4 million years ago. This places a 63-million-year expanse of time between the last non-avian dinosaurs and the earliest humans.
The Higher School Certificate (HSC) is the credential awarded to secondary school students who successfully complete senior high school level studies (Years 10, 11 and 12 or equivalent) in New South Wales and some ACT schools in Australia, as well as some international schools in Singapore, Malaysia, Indonesia, China, and Papua New Guinea.
The short-term negative effects are related to the density of tourist arrivals, traffic congestion, crowding, crime level, and other stressful factors. [2] Inbound tourism also increases the spread of SARS, MERS, COVID-19, and other diseases that transmit from human to human, which recently led to closed borders, travel restrictions, canceled ...
Atmospheric nitrogen has a partial pressure of approximately 0.78 bar at sea level. Air in the alveoli of the lungs is diluted by saturated water vapour (H 2 O) and carbon dioxide (CO 2), a metabolic product given off by the blood, and contains less oxygen (O 2) than atmospheric air as some of it is taken up by the blood for metabolic use. The ...
Phylogenetic analysis predicts that 2% of early H. sapiens would be murdered, rising to 12% during the medieval period, before dropping to below 2% in modern times. [470] There is great variation in violence between human populations, with rates of homicide about 0.01% in societies that have legal systems and strong cultural attitudes against ...
