The dermis has two major layers. Which layer contains the area where the dermis pushes into the epidermis with finger-like projections?

A. glucose is formed from noncarbohydrate molecules:Gluconeogenesis is the metabolic process in which glucose is synthesized from noncarbohydrate precursors such as amino acids, lactate, and glycerol. This process primarily occurs in the liver and helps maintain blood glucose levels during fasting or intense exercise.

B. glycogen is formed:The formation of glycogen from glucose is called glycogenesis, not gluconeogenesis. Glycogenesis stores glucose for later use rather than producing it from noncarbohydrate sources.

C. glucose is converted into carbon dioxide and water:The breakdown of glucose into carbon dioxide and water occurs during cellular respiration, specifically glycolysis, the Krebs cycle, and oxidative phosphorylation, not gluconeogenesis.

D. glycogen is broken down to release glucose:The breakdown of glycogen to release glucose is called glycogenolysis. This process provides glucose when energy is needed but does not involve the formation of glucose from noncarbohydrate sources.

A. skeletal MT:Skeletal muscle tissue is striated and voluntary, with long multinucleated fibers. The nuclei are located at the periphery of the cells, making it different from the muscle type described.

B. cardiac MT:Cardiac muscle tissue is striated and involuntary, with cells that usually contain one centrally located nucleus. It also features intercalated discs that allow synchronized contraction, matching the characteristics given.

C. smooth MT:Smooth muscle tissue is involuntary but non-striated. The cells are spindle-shaped with a single central nucleus, so it does not meet the description that includes striations.

D. All types of muscle tissue have these characteristics:Not all muscle types share striations, involuntary control, and a single central nucleus. This description specifically fits cardiac muscle tissue rather than all types.
