    • D.

      Not answered by this graph

    Correct Answer
    A. Increases
    Explanation
    The image shows a graph with light intensity on the x-axis and the rate of photosynthesis on the y-axis. As the light intensity increases, the rate of photosynthesis also increases. This can be seen from the upward trend of the graph. Therefore, the correct answer is "Increases".

  • 3. 

    This kingdom consists of prokaryotic cells commonly found in a classroom.

    • A.

      Archea

    • B.

      Protists

    • C.

      Eubacteria

    • D.

      Fungi

    Correct Answer
    C. Eubacteria
    Explanation
    The correct answer is Eubacteria because prokaryotic cells are typically found in this kingdom. Eubacteria are single-celled organisms that lack a nucleus and other membrane-bound organelles. They are commonly found in various environments, including classrooms. Archaea are also prokaryotes, but they are typically found in extreme environments. Protists are eukaryotic organisms, while fungi are a separate kingdom of eukaryotes. Therefore, Eubacteria is the most appropriate choice based on the given information.

    Rate this question:

  • 4. 

    This kingdom consists of heterotrophic organisms with a cell wall, commonly decomposers.

    • A.

      Archea

    • B.

      Protists

    • C.

      Eubacteria

    • D.

      Fungi

    • E.

      Animals

    Correct Answer
    D. Fungi
    Explanation
    Fungi is the correct answer because fungi are heterotrophic organisms that have a cell wall. They obtain their nutrients by decomposing organic matter, making them common decomposers. This kingdom includes organisms such as mushrooms, molds, and yeasts.

    Rate this question:

  • 5. 

    This kingdom consists of heterotrophic organisms lacking a cell wall.

    • A.

      Archea

    • B.

      Protists

    • C.

      Eubacteria

    • D.

      Fungi

    • E.

      Animals

    Correct Answer
    E. Animals
    Explanation
    Animals are the correct answer because they are heterotrophic organisms that lack a cell wall. Unlike plants and fungi, animals do not have a rigid cell wall made of cellulose or chitin. Instead, they have flexible cell membranes that allow for movement and interaction with their environment. Animals obtain their nutrients by consuming other organisms or organic matter, making them heterotrophs. This distinguishes them from autotrophic organisms like plants and algae, which can produce their own food through photosynthesis.

    Rate this question:

  • 6. 

    This term describes organisms capable of obtaining (and storing) energy from inorganic sources (such as water and carbon dioxide and light).

    • A.

      Heterotroph

    • B.

      Autotroph

    • C.

      Prokaryote

    • D.

      Eukaryote

    Correct Answer
    B. Autotroph
    Explanation
    Autotrophs are organisms that can produce their own food using inorganic sources such as water, carbon dioxide, and light. They are capable of converting these sources into energy through processes like photosynthesis. Unlike heterotrophs, which rely on consuming organic matter for energy, autotrophs have the ability to store and utilize energy from inorganic sources. This allows them to sustain themselves and play a vital role in the food chain by providing energy for other organisms.

    Rate this question:

  • 7. 

    A Purple, Tall pea plant (AaBb) is crossed with another Purple, Tall pea plant (AaBb).  Out of sixteen offspring, how many would you expect to be Purple, dwarf?

    • A.

      1

    • B.

      3

    • C.

      4

    • D.

      9

    • E.

      12

    Correct Answer
    B. 3
    Explanation
    In this question, the parents are both heterozygous for the purple and tall traits (AaBb). When these parents are crossed, the possible combinations of alleles in the offspring are AB, Ab, aB, and ab. Out of these combinations, only Ab and aB would result in a purple, dwarf phenotype. Since there are two possible combinations that would result in the desired phenotype, we can expect 2 out of the 16 offspring to be purple, dwarf. Therefore, the correct answer is 3.

    Rate this question:

  • 8. 

    A Purple, Tall pea plant (AaBb) is crossed with another Purple, Tall pea plant (AaBb).  Out of sixteen offspring, how many would you expect to be Purple, Tall?

    • A.

      1

    • B.

      3

    • C.

      4

    • D.

      9

    • E.

      12

    Correct Answer
    D. 9
    Explanation
    When two plants with the genotype AaBb are crossed, there are four possible combinations of alleles in the offspring: AB, Ab, aB, and ab. Each combination has an equal chance of occurring, so there is a 1/4 probability of each. Out of the sixteen offspring, 1/4 of them would have the genotype AaBb, which represents being purple and tall. Therefore, we would expect 1/4 of sixteen, which is 4, to be purple and tall.

    Rate this question:

  • 9. 

    Which of the following represents a recessive genotype?

    • A.

      Purple

    • B.

      Dwarf

    • C.

      AA

    • D.

      Aa

    • E.

      Aa

    Correct Answer
    E. Aa
    Explanation
    The recessive genotype is represented by "aa". In genetics, a recessive genotype refers to a pair of alleles where the trait associated with that allele is only expressed when both alleles in the pair are the same. In this case, the lowercase "a" represents the recessive allele, and since both alleles are "a" in "aa", it indicates a recessive genotype.

    Red/green color-blindness is a recessive, sex-linked trait.  A woman is a carrier and her husband is not color-blind.  What percent of the sons will be color-blind?  What percentage of their daughters will be color-blind?

    • A.

      0%; 0%

    • B.

      50%; 0%

    • C.

      50%; 50%

    • D.

      100%; 0%

    Correct Answer
    B. 50%; 0%
    Explanation
    Since red/green color-blindness is a recessive, sex-linked trait, the woman being a carrier means that she has one normal allele and one color-blind allele. The husband, being not color-blind, has two normal alleles. When they have children, there is a 50% chance that a son will inherit the color-blind allele from the mother and be color-blind. However, since daughters inherit one normal allele from the father and one normal allele from the mother, they will not be color-blind. Therefore, the percent of sons that will be color-blind is 50% and the percentage of daughters that will be color-blind is 0%.

  • 11. 

    Most corn being planted in South Dakota is transgenic, meaning ....

    • A.

      It contains DNA

    • B.

      It is the result of decades of selective breeding

    • C.

      It has genes from more than one organism

    • D.

      Mutations have lead to resistance to common pests

    Correct Answer
    C. It has genes from more than one organism
    Explanation
    The correct answer is "It has genes from more than one organism." This means that the corn being planted in South Dakota has been genetically modified to contain genes from multiple organisms. This genetic modification is done to introduce desirable traits into the corn, such as resistance to pests or tolerance to herbicides. By incorporating genes from different organisms, scientists can enhance the characteristics of the corn and improve its overall performance.

    According to this cladogram, lampreys ....

    • A.

      Have jaws but lack fingers and toes

    • B.

      Are not vertebrates

    • C.

      Are vertebrates but lack jaws, fingers and toes

    • D.

      Are vertebrates with jaws but no toes

    Correct Answer
    C. Are vertebrates but lack jaws, fingers and toes
    Explanation
    According to the cladogram, lampreys are vertebrates but lack jaws, fingers, and toes. This means that lampreys have a backbone and are classified as vertebrates, but they do not possess jaws, fingers, or toes like other vertebrates such as mammals or reptiles.

    Rate this question:

  • 13. 

    According to this cladogram,

    • A.

      Lungfish are more closely related to amphibians than sharks.

    • B.

      Land vertebrates share no traits with lungfish

    • C.

      Sharks and bony fish do not share any common ancestors.

    • D.

      Bony ribs evolved multiple time in Earth history.

    Correct Answer
    A. Lungfish are more closely related to amphibians than sharks.
    Explanation
    The cladogram is a diagram that shows the evolutionary relationships among different species. In this case, the cladogram suggests that lungfish and amphibians share a more recent common ancestor than lungfish and sharks. This means that lungfish and amphibians are more closely related to each other than lungfish and sharks. The cladogram does not provide any information about land vertebrates sharing traits with lungfish or about the common ancestors of sharks and bony fish. Additionally, the cladogram does not indicate how many times bony ribs evolved in Earth's history.

    • C.

      Release energy stored in food

    • D.

      Allow plants to go through photosynthesis

    Correct Answer
    C. Release energy stored in food
    Explanation
    Respiration involves oxygen and breathing, but we need these things to release the energy stored in our food (simple form = glucose).

      Plants

    • D.

      Animals and Fungi Only

    • E.

      Animals, Fungi and Plants

    Correct Answer
    E. Animals, Fungi and Plants
    Explanation
    Respiration releases energy from food (sugar). If plants didn't undergo respiration, they couldn't use the sugar they make. Remember bean seed in respiration lab!
