BIOLOGY HESI A2
In the hierarchic system of classification which is the least inclusive? - ANS Species
After observing an event, you develop an explanation this is: - ANS Hypothesis
A molecule of water is bonded with another molecule of water by what type of bond? -
ANS Hydrogen
Which is a benefit of the intermolecular hydrogen bonding of water: - ANS 1- Water
has a relatively high specific heat value.
2- Water has strong cohesive and adhesive properties.
3- Polarity of water allows it to act as a versatile solvent.
