What is positive feedback? - - ANS✔️--An end product speeds up its own production.
When a cation and anion are attracted to each other, this is known as a(n) - - ANS✔️--ionic bond.
The attraction between a hydrogen covalently bonded to one electronegative atom and another
electronegative atom is called a - - ANS✔️--hydrogen bond

Electrons are not evenly distributed; at any instant, they may accumulate by chance in one part of
a molecule or another, causing every-changing regions of positive and negative charge that
enable all atoms and molecules to stick to one another, known as - - ANS✔️--Van der Waals
interactions.
Capacity to cause change is known as - - ANS✔️--energy
Example of potential energy? - - ANS✔️--Molecule of glucose.
In the case of H20, the oxygen atom covalently bonds unequally with 2 hydrogen atoms. This is
why H20 is considered a _______ molecule. - - ANS✔️--polar
Water molecules are capable of bonding with four neighboring water molecules because - -
ANS✔️--surrounding oxygen atoms are constantly bonding with other surrounding hydrogen
atoms, which are simultaneously bonded to another oxygen atom.
What contributes to the transport of water up plants against gravity? - - ANS✔️--Cohesion
Attraction between water and another substance (for example, between water and plant cell wall)
is known as - - ANS✔️--Adhesion
A spider walking on water is an example at water's high - - ANS✔️--surface tension.

By absorbing heat from air that is warmer, and releasing stored heat to cooler air, water is - -
ANS✔️--moderating air temperature.
A liquid that is a completely homogeneous mixture of substances is a - - ANS✔️--solution.
A dissolving agent of a solution is a - - ANS✔️--solvent.
The substance that is dissolved is the - - ANS✔️--solute
A substance that does not have an affinity for water is - - ANS✔️--hydrophobic.
A substance that does have an affinity for water is - - ANS✔️--hydrophilic.
The method to describe how acidic or basic a solution is known as - - ANS✔️--pH.
A substances that *reduces* hydrogen ion concentration of a solution is called as - - ANS✔️--
base.
A substance that *increases* the hydrogen ion concentration of a solution is a(n) - - ANS✔️--
acid.
What is negative feedback? - - ANS✔️--Accumulation of the end product slows its production.
