Active Transport
These cells, commonly found in Simple & Pseudostratified Columnar tissue, secrete mucous.
Goblet Cells.
The epidermis is made up of ________ __________ epithelial tissue.

Ground Substance, Fibers, Fibroblasts.
In the Hair Growth stage known as ________, hair growth completely stops, and the hair shaft detaches from the follicle.
Of the 6 Functions Definitive of Human Life, one is described as: "The Ability of an organism to adjust to changes in its internal & external environment."
Responsiveness
When an atom gains a _______, it becomes a heavy _______.
Neutron, Isotope.
The diffusion process for substances that cannot cross the cell membrane due to size and/or charge. It does not require energy, but commonly requires membrane-bound proteins.
Facilitated Diffusion.
This type of connective tissue is commonly found directly underneath epithelial tissue, and plays important roles in protecting and supporting that epithelial tissue.
Areolar Tissue.
This type of sweat gland becomes active during puberty, is commonly found in axillary and groin areas, and empties secretions into hair follicles.
Apocrine sweat glands.
In the Homeostatic Mechanism involved in thermoregulation, what are the THREE effectors activated in response to body temperature being lowered below the set point.
Sweat Glands, Blood Vessels, and Skeletal Muscles.
The 3 components of a nucleotide are _____, _____, and _____.

During Translation, the 3 nucleotide sequence known as the _______ on mRNA binds a complimentary 3 nucleotide sequence on tRNA called the ________.
Codon, tRNA, Anticodon.
This type of secretion occurs when a portion of the cell is pinched off, but the cell remains functional because the nucleus and the Golgi apparatus remain intact.
