40. Electrons
ANSWER IS:
D. are the subatomic particles most involved in bonding behavior of atoms.
EXPLANATION:
Electrons are subatomic, negative charge particles that orbit the nucleus of an atom. They are important for the bonding of individual atoms together.
41. The epidermis of the skin is composed of
ANSWER IS:
C. stratified squamous epithelium.
EXPLANATION:
The epidermis consists of stratified squamous epithelium.
The dermis consists of connective tissue (areolar, dense irregular, blood), smooth muscle (erector pili muscles), nervous tissue (nerves)
42. A buffer will
ANSWER IS:
B. resist drastic changes in the pH of the solutions
EXPLANATION:
A buffer is a solution of weak acid and conjugate base or weak base and conjugate acid which is used to resist drastic changes in the pH of the solutions.
43. A general characteristic of connective tissue is that it
ANSWER IS:
A. consists of cells with much intercellular material (matrix) between them.
EXPLANATION:
Connective tissue is the most abundant and widely distributed and includes fibrous tissues, fat, cartilage, bone, bone marrow, and blood.
44. The energy stored in ATP is a form of
ANSWER IS:
B. chemical
EXPLANATION :
The ATP molecule store energy in the form of a high energy phosphate bond that join the terminal phosphate group to the rest of the molecule. Energy released for biochemical reactions.
