BIOH111 EXAM QUESTIONS AND ANSWERS WITH COMPLETE
SOLUTIONS GRADED A++ LATEST UPDATE
Homeostasis
A condition of equilibrium or balance in the body's internal environment produced by the
interplay of all the body's regulatory processes
Organelles
Specialised structures with characteristic shapes and specific functions
DNA
Molecule composed of 2 strands twisted around to form a double helix
Transcription
Process by which information encoded in DNA is copied onto a strand of RNA called
messenger RNA (mRNA)
Translation
The process of reading the mRNA nucleotide sequence to determine the amino acid
sequence of the protein
Amphipathic
Has polar and non polar parts
Passive transport
Diffusion is the random mixing of particles (solutes) that occurs in a solution (solvent) as
a result of the kinetic energy of the particles. Molecules of solvent and solution diffuse
from high to low concentrations.
