possessing homeostatic mechanism
the ability to adapt
the ability to evolve
the ability to run
26
Saturated and unsaturated differ from the following EXCEPT
their consistency at room temperature
they have different number of carbons in their chains
they have different number of hydrogens
they both have straight chains with no kinks or bends
27
Which of the following is NOT a characteristic of living organisms?
evolution
growth and development
disorganization
ability to respond to stimuli
28
Solid water floats. This means that
organisms in bodies of water can survive under the icy cover
solid water is less dense than liquid water
there is more space between the molecules in ice form
is due to the hydrogen bonding
29

adhesion
cohesion
surface tension
both cohesion and adhesion
35
the characteristic way in which atoms of an element react is most related to the
the number of electrons in the innermost shell
