Atto- is a unit prefix in the metric system denoting a factor of 10−18 or 0.000000000000000001. Together the two-unit exponents will almost cancel out, as 31 trillion kilometers can be written as 3.1×1018cm, meaning that an attoparsec is 3.1 cm. The unit is only used three times ...
Leaf and soil phosphorus covaried, but after controlling for elevation, no nutrient metric accounted for any additional variance in photosynthetic traits. Primary production was predicted to decline with elevation. This analysis unifies leaf and ecosystem observations in a common theoretical framework. ...
Tape measurestrips, of the 'spring metal' kind are manufactured with a slight inherent curve upwards, laterally, where not curved along their length (e.g. whilst still on the spool). Extending the tape straight out from the spool, the sideways curve dominates and adds structural strength toke...
