Cell Structure
Which of these structures are present in plant cells, but not animal cells?
cell wall and chloroplasts
What is the role of ATP in a cell
provides energy like a rechargeable battery
As a result of mitosis, the cells of a multicellular organism share which of these properties?

The human brain contains different regions that control specific bodily functions. On a model how can you identify the region of the brain that is responsible for voluntary activities of the body like learning and judgement.
The cerebrum, the largest region of the brain.
What is the difference between primary succession and secondary succession?
Primary has no living organism left after an event, while secondary will have remnants of living organisms.
A student is developing a model to show how most proteins are synthesized in animal cells. Which organelles would be LEAST useful for the student to include in the model?
chloroplasts
Which statement accurately describes the role of the light-independent reactions?
transforming light energy into chemical energy (for the plants to make their own food)
In eukaryotic cells, DNA is packaged with proteins into structures called chromosomes. What advantage do chromosomes provide the cell?
They allow random distribution of genetic material when a cell divides
The function of the circulatory system can be affected by a variety of factors, including disease and genetic disorders. Which of the following changes to the circulatory system would cause oxygen-rich blood to mix with oxygen-poor blood, and thus reduce oxygen distribution to all body cells?
A hole develops between the two sides of the heart, allowing blood to flow in both directions.
In the Linnean system of classification phylum usually distinguishes chordates (having a backbone) class distinguishes characteristics like mammary glands or gills, what are the five main classes?
mammals, reptiles, amphibians, avians, fish
A student is comparing the cells of a prokaryote, an animal, and a plant. Identifying which two cell parts would show that the cell was a prokaryotic cell, and not a cell of a plant or an animal?
flagellum and no nucleus
Which of the following describes the role of photosynthesis in the carbon cycle?
a transfer of carbon from the atmosphere (air) to the biosphere (land and living things)
Cells spend most of their life time in which phase?
Interphase ( G1 - S - G2)
Physicians recommend that children receive vaccines against a variety of infectious diseases. Which condition is necessary for the vaccine against polio to provide lifelong immunity?
Specific antigens of the virus that causes polio must remain the same over time.
What is the name of the consumer that consumes waste and dead organisms?
Detrivores
What is the lysosome used for in a cell?
To breakdown cellular waste, pathogens, and damaged cell parts
In a model summarizing cellular respiration, which of the following must be represented as raw materials, or the reactants of the process?
glucose and oxygen
Which event occurs in meiosis, but not mitosis?
Homologous chromosomes pair to form a tetrad (set of four daughter cells)
What is an example of mechanical digestion that occurs in the human digestive?
The stomach walls churn and can break down the food
In a food web an interlink of animals and plants is shown. Plants are known as primary producers and obtain 100% of energy while an owl would be known as a tertiary consumer and has 1% of the energy. What is the correct trophic name of both of these animals
Autotroph and heterotroph
Which of the following describes the structure and function of the cell membrane?
The cell membrane is made up of phospholipids and protein pumps that allow things in and out of the cell. The
What happens when no oxygen is present?
anaerobic respiration which can lead to lactic acid or alcoholic fermentation
A cell undergoes meiosis. How do the gametes it produces compare with the original cell and with one another?
The gametes have half the chromosomes of the parent cell and are genetically different
Both the liver and kidneys are organs of the excretory system. How do the two organs work together to complete a task?
The liver converts nitrogenous wastes into urea, and the kidneys filter urea from the blood.
Symbiosis is known as the interaction between two living organisms. In which form of symbiosis does one animal benefit from the relationship while the other remains unharmed?
Commensalism
