IVY TECH APHY 101 midterm exam
- ANS-growth of body parts
A body has been sectioned in such a way that there is one whole lung per section and the
urinary bladder has been split in half. What type of section is this? - ANS-sagittal
A burn affecting only the epidermis is a - ANS-superficial partial-thickness burn
A cell is surrounded by an extremely thin, flexible membrane. Why is the membrane selectively
permeable? - ANS-It allows some substances to pass through and excludes others based on
size, polarity, and other factors.
A complete atom is electrically neutral because - ANS-the number of electrons equals the
number of protons.
A hypotonic solution - ANS-has a lower concentration (number) of impermeant solute than do
the cells in the solution.
A mutation can cause disease if - ANS-the DNA sequence changes so that one amino acid is
substituted for another in a way that affects the encoded protein's functioning.
A peptide bond forms between - ANS-adjacent amino acids
A person has alkalemia if the blood pH - ANS-rises above 7.5.
An isotonic solution - ANS-has the same osmotic pressure as the cells in the solution
Anatomy and physiology are difficult to separate because - ANS-physiological functions depend
on anatomical structures.
As cells are pushed from the deeper portion of the epidermis toward the surface, - ANS-they die
ATP is important to cellular processes because it - ANS-provides energy for cellular work when
the terminal, high-energy bond is broken.
Blood cells are produced in the organs of the __________system. - ANS-skeletal
Body heat is lost primarily by - ANS-radiation
Bone cells and muscle cells differ in structure and function because - ANS-each expresses a
different subset of genes.
, Bone cells form concentric circles around longitudinal tubes called - ANS-central canals
Cells are placed in a solution that causes them to absorb liquid until they burst. When more
water is removed from the solution, newly added cells do not burst. The original solutions was
__________ , while the second was __________ to the cells. - ANS-hypotonic; isotonic
Dehydration synthesis reactions __________ , whereas hydrolysis reactions __________ . -
ANS-lose H2O as bonds are formed; use H2O to break bonds
DNA and RNA differ in that - ANS-DNA holds genetic information and RNA uses that
information to synthesize protein.
Eccrine sweat glands - ANS-respond primarily to elevated body temperature
Endoplasmic reticulum is best described as a - ANS-network of interconnected membranes
Epidermis is __________, whereas dermis is __________. - ANS-composed of stratified
squamous epithelial tissue; composed of connective tissue, smooth muscle, and nerve cell
processes
Exposure to ultraviolet light darkens skin by stimulating synthesis of - ANS-melanin
Exposure to ultraviolet radiation greatly increases the risk of developing - ANS-skin cancer
For which of the following organelles are the structure and function correctly described? -
ANS-Endoplasmic reticulum—a network of interconnected membranes forming sacs and canals
that packages protein molecules for secretion
Functions of neuroglia include which of the following? - ANS-They support and bind nervous
tissue and provide nutrients and growth factors to neurons by connecting them to blood vessels.
Histology is the study of - ANS-tissues
Homeostasis exists if concentrations of water, nutrients, and oxygen in the body are balanced
and heat and pressure __________. - ANS-remain within certain limited ranges
If one strand of DNA has the sequence TCAGGCTATTCCCG, then the complementary
sequence of the other strand is - ANS-AGTCCGATAAGGGC.
If the concentration of glucose in the water outside of a cell is higher than the concentration
inside, - ANS-water will leave the cell by osmosis
In all organisms, the basic unit of structure and function is - ANS-the cell
