Bio 180 Exam 5 BYUI
BIO 180 EXAM 5 (BYUI) EXAM COVERAGE
The BIO 180 Exam 5 at BYU-Idaho evaluates understanding of
advanced introductory biology concepts related to genetics,
evolution, and organism diversity. The exam coverage includes DNA
structure and replication, gene expression, protein synthesis, and
inheritance patterns including Mendelian and non-Mendelian
genetics. It also assesses principles of evolution such as natural
selection, genetic drift, and speciation, along with interpretation of
biological data and experimental results. Additional areas include
classification of organisms, basic ecology concepts, and adaptation
mechanisms. Overall, the exam ensures students can apply core
biological principles to explain genetic processes, evolutionary
change, and biological diversity.
,The dissociation constants for epinephrine and norepinephrine on
beta2-adrenergic receptors are 0.50 and 0.10 nM, respectively. Which
of these ligands is more efficient in activating the beta2-receptors?
Norepinephrine
Which type of receptor is most associated with metabolism, cell
growth, and cell division?
Tyrosine kinase receptors
,Which type of receptor is a dimer that when bound to the proper
ligand autophosphorylates?
Tyrosine kinase receptors
A drug designed to inhibit the response of cells to testosterone would
almost certainly result in which of the following?
A decrease in transcriptional activity of certain genes.
, Binding of a signaling molecule to which type of receptor leads
directly to a change in distribution of ions on opposite sides of the
membrane?
Ligand-gated ion channel
Which type of signaling is long-distance signaling mediated by
chemicals released into the blood?
Endocrine signaling
