MASTERING BIO 253 EXAMS: A+ GRADED GUIDE WITH
LATEST QUESTIONS AND ANSWERS.
What does adenine pair with?
Thymine
What does Guanine pair with?
Cytosine
What does uracil replace and where?
Thymine and in mRNA
What does Uracil pair with?
Adenine
Anticodon is the same as what?
mRNA
Osmosis
Diffusion of water through a selectively permeable membrane
Diffusion is
movement of molecules from an area of high concentration to an area of low concentration
facilitated diffusion uses
Proteins
no ATP is needed
PASSIVE
Simple diffusion
Moves on their own
PASSIVE
Higher concentration gradient results in
higher rate of diffusion
organic compounds
Carbon and hydrogen must be present
inorganic compounds
Compounds that do not contain carbon
Coenzyme
, Organic, attached to enzyme
Cofactor
Inorganic, No direct attachment to enzyme
Negative Feedback
Most common in the body, returns body back to normal
positive feedback
Deviates from normal
Homeostasis
Maintain a constant internal environment
Anabolism
BUILDS molecules required for bodies functionality
Example of anabolism
dehydration
Catabolism
Breaks down molecules into smaller, easier to absorb molecules
example of catabolism
Hydrolysis
What are the body cavities?
dorsal and ventral
Dorsal Body cavity
contains the cranial cavity and spinal column
ventral body cavity
thoracic and abdominopelvic cavities
What are the 3 types of muscle tissue?
skeletal, smooth, cardiac
Characteristics of skeletal muscle tissue
Striated, multinucleated, voluntary
Characteristics of smooth muscle tissue
