In photosynthesis, chlorophyll performs which of the following functions?
It changes hydrogen bonds into water.
It changes light energy into chemical energy.
It changes glucose molecules into starch.
It changes water and carbon dioxide into sugars.
All life depends on the availability of usable energy. When is this energy released?
when animal cells carry out the process of respiration
when respiration occurs in the cells of plants
when plants convert solar energy into chemical energy
when animal cells synthesize starch and carbon
After photosynthesis is complete, which of the following will most likely happen to the energy provided by sunlight?
It will be given off as heat.
It will be released into the air.
It will be absorbed by the water produced.
It will be stored in glucose molecules.
An important step in cellular respiration is
the creation of phosphate.
the creation of oxygen.
the breakdown of carbon dioxide.
the breakdown of glucose.
Which question can the student answer using the diagram?
Where is water stored in the process of cellular respiration?
What are the inputs and outputs in the process of photosynthesis?
Where is glucose stored after it is created through photosynthesis?
What is the ratio of glucose and water created through cellular respiration?
What is the purpose of photosynthesis?
to break down sugars and give energy
to break down sugars and give energy
to create oxygen for animals to breathe
to make sugars and store energy
What process do your cells perform to obtain energy from the glucose you eat?
Osmosis
Diffusion
Photosynthesis
Cellular Respiration
What statement best compares the biochemical processes of photosynthesis and cellular respiration?
Photosynthesis is the bacterial process of creating energy while cellular respiration is the eukaryotic process of releasing energy.
Photosynthesis is the process of trapping the energy of the sun and storing it in glucose. Cellular respiration is the process of releasing the energy stored in the chemical bonds of glucose.
Photosynthesis is the plant process of releasing and utilizing energy while cellular respiration is the animal process of releasing and utilizing energy.
Photosynthesis is the process of trapping the energy of glucose. Cellular respiration is the process of releasing the energy stored in the bonds of the cell.
How does the cell obtain energy for the process?
The cell obtains the needed energy from food.
the cell obtains the needed energy from sunlight.
the cell makes the needed energy from soil nutrients
the cell makes the needed energy in mitochondria.
Which of the following correctly identifies the type(s) of cell division described in rows X and Y?
Row X and Y describe mitosis.
Row X and Y describes meiosis.
Row X describes meiosis, while row Y describes mitosis.
Row X describes meiosis, while row Y describes meiosis.
The diagram below provides information about a carrot cell. A carrot cell contains 18 chromosomes. Which of the following diagrams illustrates the correct number of chromosomes in new cells produced by mitosis?
Which statement correctly uses the model to explain how mitosis maintains genetic continuity?
The chromosomes in cell 1 are the same as in cells 6 and 7.
Crossing-over occurs in cell 4, which increases the genetic diversity in cells 6 and 7.
When the nuclear membrane reforms in cell 5, each nucleus becomes diploid in number.
The independent assortment that is represented in cell 2 ensures that cell 3 has the correct number of chromosome.
Julia and Vinay's teacher was walking around the laboratory
during the experiment asking students questions to deepen their thinking about their results. She told Julia and Vinay that one of the cell samples contains bacteria. Then she asked them, "How would you describe the process of genetic information being passed from parent to offspring in organisms like bacteria?"
Which response would most accurately answer the question Julia and Vinay's teacher posed?
The organism undergoes mitosis and creates genetically diverse offspring.
The organism undergoes meiosis and creates genetically diverse offspring.
The organism undergoes binary fission and creates genetically identical offspring.
The organism undergoes sexual reproduction and creates genetically identical offspring.
Which best explains how binary fission contributes to the genetic continuity of a population?
Binary fission maintains genetic continuity because the daughter cells contain twice as many chromosomes as the parent cell.
Binary fission maintains genetic continuity because the daughter cells contain the same number of chromosomes as the parent cell.
Binary fission does not maintain genetic continuity because the daughter cells contain the same number of chromosomes as the parent cell.
Binary fission does not maintain genetic continuity because the daughter cells contain a smaller number of chromosomes than the parent cell.
Which model correctly shows how the process of mitosis affects genetic continuity?
Model 1 because during mitosis, two daughter cells receive half of the chromosomes of the parent cell.
Model 2 because during mitosis, one daughter cell receives the same number of chromosomes as the parent cell.
Model 3 because during mitosis, two identical daughter cells receive the same number of chromosomes as the parent cell.
Model 4 because during mitosis, four daughter cells receive one quarter of the chromosomes of the parent cell.
If an environment experiences change, which BEST predicts the population that is MOST LIKELY to survive?
the population that reproduces asexually and undergoes mitosis
the population that reproduces sexually and undergoes mitosis
the population that reproduces asexually and undergoes meiosis.
the population that reproduces sexually and undergoes meiosis

Fertilization
Which of the following describes how both of these cellular division processes maintain genetic continuity?
Both processes creates cells with half the genetic material of the parent cells.
Both processes create cells with twice the genetic material of the parent cells.
Both processes involve the replication and division of identical genetic material.
Both process involve the recombination and division of new genetic material.
Which statement regarding this process is correct?
