Questions and Answers
  • 1. 

    Which of these is NOT true about all living organisms?

    • A.

      They are composed of one or more cells.

    • B.

      They contain DNA.

    • C.

      They must all have a brain.

    • D.

      They can extract energy from the environment.

    Correct Answer
    C. They must all have a brain.
    Explanation
    The statement "They must all have a brain" is not true about all living organisms. While some organisms, such as humans and other animals, have a brain, there are many living organisms that do not possess a brain. For example, bacteria and other single-celled organisms do not have a brain but are still considered living organisms. Therefore, the presence of a brain is not a universal characteristic of all living organisms.

    Which of these is not a 'Domain of Life'?

    • A.

      Archaea

    • B.

      Bacteria

    • C.

      Eucaryote

    • D.

      Prokaryote

    Correct Answer
    D. Prokaryote
    Explanation
    Prokaryote is not a 'Domain of Life' because it is a type of cellular organization, not a specific domain. The three domains of life are Archaea, Bacteria, and Eukaryota. Archaea and Bacteria are both prokaryotes, meaning their cells lack a nucleus and other membrane-bound organelles. Eukaryota, on the other hand, includes organisms with cells that have a nucleus and other membrane-bound organelles. Therefore, Prokaryote is not a domain but a characteristic of certain organisms within the domains Archaea and Bacteria.

    Which of these following combination is possible?

    • A.

      A+g

    • B.

      T+t

    • C.

      C+t

    • D.

      T+a

    Correct Answer
    D. T+a
    Explanation
    The given combination "t+a" is possible because in DNA, the nucleotides can pair up in a specific way. Adenine (A) always pairs with Thymine (T), and Guanine (G) always pairs with Cytosine (C). Therefore, the combination of Thymine (T) and Adenine (A) is a valid pairing.

    DNA transcribes into ______ which translates into ______.

    Correct Answer
    DNA transcribes into RNA which translates into Protein.
    RNA Protein
    RNA protein
    Explanation
    The process of transcription involves the synthesis of RNA from a DNA template. This RNA molecule then undergoes translation, where it is used as a template to synthesize a protein. Therefore, DNA transcribes into RNA, and this RNA translates into protein. The answer provided correctly states this sequence of events.

  • 7. 

    The earth is

    • A.

      4.54 billion years old

    • B.

      45.4 million years old

    • C.

      45.4 billion years old

    • D.

      4.54 million years old

    Correct Answer
    A. 4.54 billion years old
    Explanation
    The correct answer is 4.54 billion years old. This is the generally accepted age of the Earth based on scientific evidence, such as radiometric dating of rocks and minerals. These dating methods have been used to determine the age of the Earth's oldest rocks, which provide a minimum age estimate for the planet. Additionally, the age of meteorites and moon rocks that originated from the early solar system also support this age estimate.

    The endosymbiotic theory is the theory that eukaryote cells evolved as a collection of bacteria cells that existed in a symbiotic relationship.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The endosymbiotic theory proposes that eukaryotic cells evolved from a symbiotic relationship between different types of bacteria. This theory suggests that certain organelles, such as mitochondria and chloroplasts, were once free-living bacteria that were engulfed by a host cell and eventually became integrated into the cell's structure. This theory is supported by evidence such as the similarities between the DNA of these organelles and that of bacteria, as well as their ability to replicate independently within the cell. Therefore, the statement that the endosymbiotic theory suggests eukaryote cells evolved from a collection of bacteria cells in a symbiotic relationship is true.

    What animal did Darwin study on the Galapagos islands?

    • A.

      Giraffes

    • B.

      Finches

    • C.

      Frogs

    • D.

      Darwin never visited the Galapagos islands

    Correct Answer
    B. Finches
    Explanation
    Darwin studied finches on the Galapagos islands. The finches played a crucial role in shaping his theory of natural selection. Darwin observed that the finches had different beak shapes and sizes, which allowed them to adapt to different food sources on the islands. This led him to propose that the finches had evolved from a common ancestor and that their beak variations were the result of natural selection. This study of finches provided evidence for the idea that species can change and adapt over time, supporting Darwin's theory of evolution.

    Who performed the 'Pea plant' experiments?

    • A.

      Charles Darwin

    • B.

      Thomas Malthus

    • C.

      Alfred Russell Wallace

    • D.

      Gregor Mendel

    Correct Answer
    D. Gregor Mendel
    Explanation
    Gregor Mendel performed the 'Pea plant' experiments. He is known as the father of modern genetics for his groundbreaking work on inheritance in pea plants in the 19th century. Mendel's experiments involved cross-breeding different varieties of pea plants and meticulously tracking the traits that were passed down to subsequent generations. His observations and conclusions laid the foundation for our understanding of the basic principles of heredity and the laws of inheritance.

    Which of these is an example of artificial selection?

    • A.

      The peacock with the biggest tails mate more often.

    • B.

      Humans picking the biggest vegetables to breed.

    • C.

      The slowest antelope dieing off quicker.

    • D.

      The giraffes evolving longer necks to reach the highest leaves.

    Correct Answer
    B. Humans picking the biggest vegetables to breed.
    Explanation
    Artificial selection refers to the intentional breeding of plants or animals by humans, selecting specific traits to be passed on to the next generation. In this case, humans picking the biggest vegetables to breed is an example of artificial selection because it involves humans deliberately selecting and breeding plants with desired traits, in this case, the size of the vegetables. This process allows for the propagation of certain traits and the development of new varieties that possess desired characteristics.

    DNA regions that are transcribed into RNA are known as _____.

    Correct Answer
    Genes
    Explanation
    DNA regions that are transcribed into RNA are known as genes. Genes are specific sequences of DNA that contain the instructions for making proteins or functional RNA molecules. During the process of transcription, the DNA sequence of a gene is copied into a complementary RNA molecule, which can then be used as a template for protein synthesis or perform other cellular functions. Therefore, genes are the units of heredity that encode the information necessary for the production of specific molecules in an organism.

    • B.

      24

    • C.

      46

    • D.

      48

    Correct Answer
    A. 23
    Explanation
    Humans contain 23 pairs of chromosomes. Each pair consists of two chromosomes, one inherited from the mother and one from the father, resulting in a total of 46 chromosomes. These chromosomes carry genetic information that determines various traits and characteristics in humans.

    Rate this question:

  • 15. 

    Different versions of a gene are called _______.

    Correct Answer
    alleles
    Explanation
    Alleles are different versions or forms of a gene. Each gene can have multiple alleles, which can result in variations in traits or characteristics. These alleles can be dominant or recessive, and they determine how a specific trait is expressed in an individual. Therefore, alleles play a crucial role in genetic diversity and inheritance.

    Rate this question:

  • 16. 

    The sum of all alleles in a population is known as a(n) __________.

    Correct Answer
    Gene Pool
    Explanation
    The sum of all alleles in a population is known as a gene pool. A gene pool refers to the total collection of genes and their different alleles present in a population. It represents the genetic diversity within a population and serves as the source of genetic variation for evolution. By studying the gene pool, scientists can understand the frequency and distribution of different alleles in a population, which is crucial for understanding population genetics and evolutionary processes.

    Which of the following statements is true?

    • A.

      A Genotype depends on a phenotype.

    • B.

      A Phenotype depends on a Genotype.

    Correct Answer
    B. A Phenotype depends on a Genotype.
    Explanation
    Phenotype refers to the physical characteristics or traits exhibited by an organism, while genotype refers to the genetic makeup or combination of alleles present in an organism. The genotype determines the phenotype, as the genetic information encoded in the DNA of an organism influences the development and expression of its physical traits. Therefore, the statement "A Phenotype depends on a Genotype" is true.

    Which of these is not a requirement of Hardy-Weinberg equilibrium?

    • A.

      Mating is Random

    • B.

      There is good gene flow

    • C.

      There must be no mutations

    • D.

      There must be no selection for or against any allele

    Correct Answer
    B. There is good gene flow
    Explanation
    The requirement of Hardy-Weinberg equilibrium is that there must be no mutations, no selection for or against any allele, and random mating. However, gene flow refers to the movement of genes from one population to another, and it is not a requirement for Hardy-Weinberg equilibrium. Gene flow can introduce new genetic variations into a population, which goes against the assumption of no mutations in the equilibrium model. Therefore, "There is good gene flow" is not a requirement of Hardy-Weinberg equilibrium.

    This graph is an example of

    • A.

      Directional Selection

    • B.

      Stabilizing Selection

    • C.

      Disruptive Selection

    • D.

      Extreme Selection

    Correct Answer
    A. Directional Selection
    Explanation
    This graph is an example of directional selection because it shows a shift in the population towards one extreme phenotype. This means that individuals with traits closer to one end of the spectrum have a higher fitness and are more likely to survive and reproduce, causing the overall population to gradually shift in that direction.

    Muller's Rachet predicts that ______ populations are doomed to accumulate mutations.

    • A.

      Sexual

    • B.

      Asexual

    Correct Answer
    B. Asexual
    Explanation
    Muller's Rachet predicts that asexual populations are doomed to accumulate mutations. This is because in asexual reproduction, there is no recombination of genetic material, and mutations can only accumulate over time. Without the ability to remove deleterious mutations through recombination, asexual populations are more likely to experience a gradual decline in fitness due to the accumulation of harmful mutations. In contrast, sexual reproduction allows for the shuffling and recombination of genetic material, which can help purge deleterious mutations and maintain genetic diversity in populations.
