answers>>muscle contraction
the layer of the epidermis that contains cells undergoing division is the - correct answers>>stratum
germinativum
the pigments melanin - correct answers>>is produced by cells called melanocytes
the watery medium the surrounds our cells is known as - correct answers>>interstitial fluid
in the elderly, blood supply to the dermis is reduced and sweat glands are less active. this combination of
factors would most affect - correct answers>>the ability to thermoregulate
when stress is applied to a bone - correct answers>>the minerals in the bone produce a weak electrical
field that activates osteoblasts

, the layer of the skin that provides protection against bacteria as well as chemical and mechanical injuries
is the - correct answers>>epidermis
the molecule ATP - correct answers>>is formed from ADP and phosphate, contains high energy covalent
bonds, is the most important high energy compound in human cells, provides energy for cellular
reactions when the bond attaching the last phosphate to the molecule is broken
