BIO 201 UPDATED COMPREHENSIVE EXAM
QUESTIONS AND ANSWERS SURE A+
✔✔What is passive membrane transport; - ✔✔...substances cross the membrane
without any energy input from the cell; unlike active transport that requires energy from
the cell
✔✔What are the characteristics of Psuedostratified Columnar Epithelium - ✔✔...single
layer of cells of differing heights, some not reaching the free surface; nuclei seen at
diffrent levels; may contain mucus secreating cells and bear cilia.
✔✔What is basal metabolic rate (BMR) - ✔✔...reflects the energy the body needs to
perform only its most essential activities. ( this happens at an in rest state ; neutral)
✔✔What is Simple Squamous Epithelial tissue - ✔✔...one layer, flat egg shaped , allows
materials to pass by diffusion and filteration in sites where protection is not important;
secretes lubricating substances in serosae;
✔✔Why should elderly patients decrease their caloric intake - ✔✔...becasue their BMR
reduces dramaticly, if they increse their calorie intake they will gain weight
✔✔The functions of tRNA - ✔✔...carry amino acids to the ribosomes, there they decode
mRNA's msg for amino acid sequence in the polypeptide to be built
, ✔✔Salts are ALWAYS _______ - ✔✔...ionic compound
✔✔Which tissue is highly cellular and vascularized - ✔✔...muscle tissue
✔✔The 4 elements that comprise 90% of body matter - ✔✔...Carbon Hydrogen,
Nitrogen, Oxygen
✔✔Why is cholesterol important in our bodies - ✔✔...it is found in the bloodstream and
every cell of the body, it produces cell membranes, hormones, vitamin d, and bile acids
that help digest fat.
✔✔What are riboswitches - ✔✔...are specific components of mRNA that help with gene
expression
✔✔What codes genetic information in DNA - ✔✔...mRNA
✔✔Know what happens in the stages of mitosis - ✔✔...Early prophase-chromatic
condenses forming barlike chromosomes; Late Prophase- the nuclear envelope breaks
up, allowing the spindle to interact with the chromosomes; Metaphase-the two
centrosomes are at opposite poles of the cell; Anaphase-chromosomes split ;
Telophase- identical sets of chromosomes are at opposite ends; Cytokenises-cell
pinches apart
✔✔What tissue type comes from all 3 embryonic germ layers - ✔✔...Epithelial;
endoderm, mesoderm, ectoderm
✔✔The most abundant chemical in our body - ✔✔...h2o
✔✔Oils have many types of which type of bonds - ✔✔...double bonds- non polar
molecules
✔✔Functions of prostaglandins - ✔✔...Activation of the inflammatory response,
production of pain and fever. When tissues are damaged, white blood cells flood to the
stie to try to minimize tissue destruction. Prostaglandis are produced as a result
✔✔What type of food is best for athletic performance - ✔✔...raw fruits and vegtables
✔✔What are negative feedback mechanisms - ✔✔...is a series of reactions or process
that migrate a change or disturbance within a system to get it back to an equilibrium
state.
✔✔What are tissues - ✔✔...any of the distinct types of materail of which animals or
plants are made, consiting of specialized cells and their products
