Complete Solutions Latest Update,,.
Anatomy - AnswerArea of science that studies the location, shape, and structure of
body parts that might be involved in cutting.
Physiology - AnswerThe study of how the body parts function.
Homeostasis - AnswerThe maintenance of a stable internal environment.
Negative Feedback mechanism - AnswerSelf-regulating internal control mechanisms
that sense changes away from the normal homeostatic condition which cause reactions
that bring conditions back to normal.
Metabolism - AnswerAll Chemical and physical reactions that take place within an
organism
Chemistry - AnswerBranch of science dealing with the composition of substances and
the changes that take place in their composition.
Elements needed by living things - AnswerThere are about 20 needed for life
elements that make up 95% of the human body. - AnswerCarbon, Hydrogen, Oxygen,
and Nitrogen.
Elements - AnswerThe basic pure substances that make up all matter.
Atoms - AnswerSmallest particle that retains the physical and chemical characteristics
of an element.
Protons - AnswerAtomic particles located in the nucleus of atoms with a positive
charge.
Neutrons - AnswerAtomic particles located in the nucleus of atoms with no charge.
Electrons - AnswerAtomic particles in constant motion around the nucleus of atoms
with a negative charge.
Atomic Number - Answerthe number of protons in the nucleus of an atom
, Atomic Weight - Answerthe number of protons plus the number of neutrons of an
atom
Electron Orbitals or Electron Shells - AnswerThe location of the electrons of an atom.
Maximum number of electrons in the first electron shell. - Answer2
Maximum number of electrons in the second and third electron shell. - Answer8
Ions - AnswerCharged particles
Electrovalent bonds - Answerbonds formed by the attractive force of electrically
charged ions forming a compound
If the outermost electron shell is more than half full it will . . . . electrons - Answergain
If the outermost electron shell is less than half full it will . . . . electrons - Answerlose
Isotopes - AnswerAtoms of a particular elemant that have the same number of
protons but a different number of neutrons. Some are radioactive.
Covalent Bond - Answera chemical bond that involves sharing a pair of electrons
between atoms in a molecule
Molecular chemical formula - Answergives number of atoms of each element present
Structural chemical formula - Answershows the molecules shape
Decomposition - AnswerBonds within reactant molecule are broken forming simpler
ions or atoms or molecules. AB ----> A + B
Synthesis - AnswerTwo or more atoms bond to form a more complex structure. A + B
------> AB
Exchange - AnswerParts of two different kinds of molecules change places. AB + CD
-------> AD + CB
pH - AnswerEqual to the negative logarithm of the free hydrogen ion concentration
per liter of solution.
Acidic pH - Answer0 - 6.9
Basic pH - Answer7.1 - 14
