Ch 1: Human Body Orientation
The body’s ability to maintain relatively stable internal conditions despite continuously changing environment.
What is homeostasis?
The type of compound (acid, base, or salt) represented by the following reaction: KI —> K+ +I-
What is a salt?
A process occurring during interphase whereby DNA is duplicated to prepare for upcoming cell division (mitosis).
What is DNA replication?
Hair follicles and sweat glands are examples of accessory organs in what body system?
What is the integumentary system?
Type of epithelium that functions in secretion and absorption?
What is simple cuboidal and/or what is simple columnar epithelium?
This occurs when the net effect of a response to a stimulus changes the variable in the opposite direction from the initial stimulus. (ex.: a decrease in Ca triggers hormone release that results in increase of Ca)
What is a negative feedback mechanism?
A compound that releases an H+ when it dissolves in water.
What is an acid?
Stage of mitosis in which (a) the chromatin condenses to form bar-like chromosomes, (b) the nuclear envelope and nucleoli break down, (c) centrioles separate and move toward opposite sides of the cell directing the assembly of the mitotic spindle
What is prophase?
(Hint: Be able to state 2 things that occur during interphase and the 4 stages of mitosis: prophase, metaphase, anaphase, telophase).
The membrane lining the abdominal cavity.
What is the parietal peritoneum?
What is transcription?
The system that eliminates metabolic waste from the body.
What is the urinary system?
Two or more atoms chemically bonded together.
What is a molecule or what is a compound?
What is diffusion.
The name for the specialized epithelium that forms the protective barrier of the epidermis?
What is keratinized stratified squamous epithelium?
The component of the homeostatic control system that determines the level (set point) that a variable should be maintained.
What is the control center?
The body system that delivers oxygen and nutrients in the blood throughout the body.
What is the cardiovascular system?
Type of chemical bond in which two atoms share electrons unequally.
What is polar covalent bond?
(Hint: be able to define ionic, covalent, polar covalent bonds)
The direction Na+ will move if the concentration inside the cell is > the concentration of Na+ outside of the cell.
What is ”out of the cell”?
(Hint: be able to predict the movement of ions across membranes and water across membranes based on intracellular and extracellular ion concentrations.)
The layer of the skin that contains hair follicles, sweat glands, and blood vessels?
What is the dermis?
The process in which amino acids are bonded together to form a chain.
What is translation?
Tissue that contracts to cause movement.
What is muscle tissue?
The term for an atom with a charge on it (positive or negative).
What is an ion?
(Hint: cations are positive ions and anions are negative ions; examples of ions are Na+, K+, I-, Cl-)
The organelle that is the site of translation.
What is Ribosome (or Rough Endoplasmic Reticulum)?
The main cell type in the epidermis.
What are keratinocytes?
The molecule that brings the amino acid to the ribosome for protein synthesis (translation).
What is tRNA?
