The diagram shows cell A completing a life process.
Cell A performs functions similar to the tissues and systems in complex, multicellular organisms. This process results in
increased genetic variation
the maintenance of homeostasis
a reduction in competition
increased autotrophic nutrition
An ameba, a one-celled organism, can move, ingest, and transport materials within the cell, because it has
organs
tissue
organelles
systems
The paramecium is a single-celled organism that reproduces asexually. The offspring of a paramecium usually contain
only half the genes of the parent
more DNA than the parent cell
genetic material identical to the parent cell
fewer mutations than the parent cell
Which statement best describes what would most likely be observed after 20 minutes?
The content s of the dialysis tube would turn blue-black
The liquid in the beaker would turn blue-black
The dialysis tube would burst
There would be no change visible
Which term correctly identifies the process by which molecules move through the dialysis tube membrane?
paper chromatography
diffusion
active transport
digestion
A student filled a dialysis tube with 97% water solution and sealed the ends. The tube and its contents had a mass of 55 grams. The student placed the tube in a solution, and the mass of the tube and its contents increased to 60 grams. Into which solution was the dialysis tube placed?
0% water
97% water
95% water
99% water
The building blocks for this molecule are
amino acids
simple sugars
molecular bases
fats
The energy in this molecule is stored
in the bonds between atoms
when the carbon atom breaks off
in the oxygen found in the molecule
when water breaks this molecule
One possible conclusion that can be drawn about the activity of this cell is that
more active transport occurs
no active transport occurs
the cell uses some of the extra mitochondria to make food
the cell is a plant cell since it has a cell wall
Oriental hornets are unique insects. A yellow pigment in the body of the insect converts solar energy to electrical energy. Plants also convert energy from the Sun.
Identify the organelle present in plants where this conversion takes place.
mitochodria
ribosomes
cytoplasm
chloroplast
Which of the following statements best describes the general direction of diffusion across the membrane?
sugar would diffuse into the cell
water would diffuse into the cell
there would be no movement of water
the sugar molecule would not move
Active transport is defined as the movement of
material from high to low concentration using energy
material from low to high without the use of energy
water from high to low concentration
material from low to high with the use of energy
Passive transport is defined as
movement of molecules from high to low concentration using energy
movement of molecules from low to high using energy
movement of molecules concentration until a state of equilibrium is reached requiring no energy
no movement of molecules
What happens to a cell in salt solution
the cell will swell
the cell will shrivel
the cell will remain the same
the cell will dissolve
The energy in this molecule is stored
in the bonds between atoms
when the carbon atom breaks off
in the oxygen found in the molecule
when water breaks this molecule
