Anthony has a cut that is superficial and painful, but not bleeding. Based on this information you would predict that the cut has penetrated to
the subcutaneous layer, but no deeper
the papillary layer but not the reticular layer
the stratum basale but not the dermal layers
the stratum corneum but not the stratum granulosum
The Correct Answer is B
A. the subcutaneous layer, but no deeper: The subcutaneous layer lies beneath the dermis and contains fat and connective tissue. A cut reaching this layer would likely cause significant bleeding and deeper tissue pain, which does not match Anthony’s wound.
B. the papillary layer but not the reticular layer: The papillary layer is the upper portion of the dermis, just below the epidermis. Superficial cuts that are painful but not bleeding typically affect this layer, as it contains nerve endings that produce pain, but it is above the deeper reticular layer where larger blood vessels reside.
C. the stratum basale but not the dermal layers: The stratum basale is the deepest layer of the epidermis. While cuts affecting only this layer may cause mild discomfort, they rarely produce the type of superficial pain described, and they do not reach the dermis where more pain receptors are located.
D. the stratum corneum but not the stratum granulosum: The stratum corneum is the outermost layer of the epidermis and contains dead cells. A cut limited to this layer is usually painless and superficial, without causing noticeable pain.

Correct Answer is C
Explanation
A. anaerobic:Anaerobic respiration, such as glycolysis, occurs without oxygen and produces only a small amount of ATP, typically 2 ATP per glucose molecule. It provides quick energy but is not the main source of ATP generation in cells.
B. anabolic:Anabolic reactions involve building larger molecules from smaller ones, such as protein or glycogen synthesis. These processes consume energy rather than produce it, so they do not contribute to ATP generation.
C. aerobic:Aerobic respiration occurs in the presence of oxygen and includes the Krebs cycle and electron transport chain. This pathway produces the majority of ATP, yielding around 34–36 ATP molecules per glucose, making it the primary energy source.
D. None of the Correct answers are correct:This option does not apply because aerobic respiration is the well-established pathway responsible for generating most of the cell’s ATP.
Correct Answer is D
Explanation
A. RNA:RNA is a general term for ribonucleic acid and includes several types with different functions. It does not specifically refer to the RNA that delivers amino acids to the ribosome.
B. mRNA:Messenger RNA carries the genetic code from DNA to the ribosome, directing the sequence of amino acids in a protein, but it does not transport the amino acids themselves.
C. sRNA:Small RNA molecules (sRNA) are involved in regulatory processes within the cell, such as gene silencing, and are not responsible for delivering amino acids for protein synthesis.
D. tRNA:Transfer RNA is responsible for bringing specific amino acids to the ribosome during translation. Each tRNA recognizes codons on the mRNA and ensures that the correct amino acids are added to the growing polypeptide chain.
