Energy in this ecosystem passes directly from the Sun to
herbivores
heterotrophs
consumers
autotrophs
Identify 2 raw materials of photosynthesis
glucose & oxygen
oxygen & carbon dioxide
carbon dioxide & water
water & glucose
State one reason why photosynthesis is necessary for animals to survive
it recycles the oxygen and turns it into carbon
it recycles the carbon and turns it into oxygen
it recycles the carbon dioxide and turns it into oxygen
It recycles the oxygen and turns it into carbon dioxide
In some single-celled protozoans living in fresh water, such as the paramecium, contractile vacuoles are organelles used to pump excess water out of the cell. Explain why a paramecium would require contractile vacuoles while a similar protozoan living in salt water would not.
When an organism lives in salt water, the water will continually diffuse into the cell
When an organism lives in salt water, the water will continually diffuse out of the cell
When an organism lives in fresh water, the water will continually diffuse out of the cell
The cell membrane will not allow the water to enter of leave the cell
Which describes what would be expected to occur in the potato cells, with regard to both the starch and water molecules?
More water will move into the cell than will leave the cell. Starch will remain inside the potato cell.
More water will leave the cell than will enter. Starch will move out of the cell.
Water content of the cell will not change. Starch will move out of the cell.
More water will leave the cell than will enter. Starch will remain inside the potato cell.
Which statement correctly describes a possible result if starch indicator is added to the water in the beaker one hour after the potato cube was added?
The indicator solution would turn to an amber color in the water if starch molecules were present in the water in the beaker.
The indicator would remain amber in color if starch molecules were not present in the water in the beaker.
The indicator would change to a black color if starch molecules were not present in the water in the beaker.
The indicator solution would remain black in color if starch molecules were present in the water in the beaker.
Before placing the potato in the beaker, the student used an electronic balance to determine the mass of the potato cube. The mass of the cube was determined again after it was in the beaker for an hour. Describe how this information could specifically be used to determine if water moved during the investigation.
If the mass increased, then water moved out
If the mass increased, then water moved in
If the mass decreased, then water moved in
If the mass did not change water moved out.
Based on the information given, state one way the bag or its contents will have changed by the next day.
The artificial cell would get larger because the water would diffuse into the bag
The artificial cell would get smaller because the water would diffuse into the bag
The artificial cell would get larger because the water would diffuse out the bag
The artificial cell would get smaller because the water would diffuse out the bag
A fruit fly is classified as a consumer rather than as a producer because it is unable to
reproduce asexually
synthesize its own food
release energy stored in organic molecules
remove wastes from its body
A child with cystic fi brosis has an altered protein in his cells that stops chloride ions from leaving the cells. This protein most likely affects the functioning of
cell membranes
nuclei
mitochondria
ribosomes
The most likely result of completely removing carbon dioxide from the environment of a plant is that sugar production will
continue at the same rate
increase and oxygen production will also increase
increase and oxygen production will stay the same
decrease and eventually stop
The movement of molecules from side A to side B is an example of the process of
active transport
chromatography
cellular respiration
diffusion
Increased concern over the number of heat related illnesses among football players has led to a possible change in uniform design. Shoulder pads were designed that constantly blew cool, dry air underneath the shoulder pads. Tests showed that the use of the device during rest and recovery periods resulted in a reduction of body temperature and heart rate. This new device would help the athlete to
control the rate of muscle activity
increase muscle strength
maintain homeostasis
eliminate the release of heat from the body
In this setup, which tubes contain at least one organism carrying on cellular respiration?
tubes 1 and 2, only
tubes 3 and 4, only
tubes 2 and 4, only
tubes 2, 3, and 4, only
Which compound that directly provides energy in living cells is being produced in every tube where cellular respiration is occurring?
oxygen
DNA
glucose
ATP
The processes of diffusion and active transport are both used to
break down molecules to release energy
move molecules into or out of cells of the body
bring molecules into cells when they are more concentrated outside of the cell
move molecules against a concentration gradient, using ATP molecules
Which dissolved substance do aquatic animals remove from their external environment for use in cellular respiration?
carbon dioxide
oxygen molecules
ATP molecules
nitrogen gas
A similarity between these systems is that they all
are made of cells that are identical in structure and function
contain organs that work independently from other organs in that system
work together to maintain a stable internal environment
are separate and do not interact with other body systems
Which procedure is represented in the diagram?
adding distilled water to the top of a cover glass on a slide
making an artificial cell
adding salt solution to a specimen under the cover glass
making a thin sample to prepare a slide of red onion cells
A student is opening and closing clothespins as part of a lab activity. The student begins to experience muscle fatigue, and the rate at which the student is opening and closing the clothespins slows. Which graph best represents the relationship between time and number of clothespin squeezes?
