ECU Bio 1050 Bunnell Exam 2 Questions
Fully Solved.
what is the by-product of photosynthesis is important in altering the atmosphere of the earth so
that aerobic organisms could evolve? - Answer oxygen
a green plant can carry our photosynthesis if given nothing more than: - Answer water, light
and air
potenital energy - Answer is contained in matter placed in certain positions or arrangements
when ATP is hydrolyzed to ADP, what happens? - Answer one phosphate is removed
a pigment that reflects all wavelengths of visible light appears - Answer white
when someone puts their contact lenses into their eyes they use saline solution. this doesn't
burn because the solution is - Answer isotonic
every time a source of energy is converted from one form to another - Answer some of the
energy is converted to heat, which is one of the least usable forms of kinetic energy
the net movement of molecules from locally concentrated regions to uniform distributions is
the best described as - Answer diffusion
when electrons transfer their energy to help pump protons across the membrane against their
concentration gradient in the mitochondria is called - Answer active transport
the statement that best describes the relationship between respiration and photosynthesis -
Answer photosynthesis stores energy in complex organic molecules, while respiration releases
it
Around campus there are purple and gold pansies (flowering plants) representing ECU's colors.
What is occurring in the petals of the purple flowers? - Answer yellow light is being absorbed
the purple light is being reflected
, what is NOT a form of kinetic energy - Answer a covalent bond linking phosphate molecules
Life gains most of its energy from: - Answer sunlight
what is NOT a product of photosynthesis - Answer carbon dioxide
the movement of H+ into the stomach is accomplished through - Answer active transport
a unique characteristic of mitochondria is that they are inherited from the female parent only.
what is the correct explanation for this phenomenon? - Answer male sperm cells have
mitochondria, but because the sperm contributes DNA but no cytoplasm, no mitochondria are
passed to the egg at fertilization
what is NOT correct about fermentation - Answer all of the above are correct
the primary function of molecular membranes is the transport of ions and molecules in and out
of cell-transport is directional and selective. the moving of molecules from the areas of high
concentration to low concentration to gain energy is described as - Answer passive transport
what role does O2 play in aerobic respiration - Answer it is the final electron acceptor at the
end of the electron transport chain
Animal cells have "counters" that keep track of how many times a cell has divided. These
counters are called: - Answer telomeres
Sex cells having the ___________ number of chromosomes are called ____________. - Answer
haploid; gametes
In any DNA molecule, the number of guanine bases will: - Answer always be equal to the
number of cytosine bases
eukaryotic cells can divide by - Answer both mitosis and meiosis
