2) Maintain Homeostasis - Regulate itself to change
3) Reproduce
4) React to stimuli
5) Grow
6) Have cells
7) Evolve

2) Molecules
3) Organelle
4) Cell
5) Tissue
6) Organ
7) Organ System
8) Organism
9) Population

Nucleus - correct answer ✔The center of an atom containing the protons and neutrons.
Chemical Bonds - correct answer ✔Bonds formed between atoms transferring of protons, neutrons,
and electrons.
Ionic bond - correct answer ✔Atoms transfer a proton or neutron and then go separate ways.
Covalent bond - correct answer ✔Atoms share one electron together to maintain stability.
This bond stores and uses a lot of energy.
Non-polar covalent bond - correct answer ✔Electrons shared equally by the bonded atoms.
Polar covalent bond - correct answer ✔Electrons shared unequally by the bonded atoms.
Hydrogen bond - correct answer ✔The weak attraction between a slightly positive hydrogen atom and
a slightly negative atom.
Evaporation - correct answer ✔Liquid water gains energy and turns into a gas form.
Condensation - correct answer ✔Gas loses energy and turns into a liquid.
Heat of vaporization - correct answer ✔The amount of energy needed to make liquid evaporate.
Cohesion - correct answer ✔The tendency of water to stick to itself (water droplets).
