Questions and Answers
  • 1. 

    During Meiosis, the factors that control each trait seperate and only 1 from each pair is passed to the offspring. (created my Mendel)

    • A.

      Crossing Over

    • B.

      Aerobic Process

    • C.

      Law of Segregation

    Correct Answer
    C. Law of Segregation
    Explanation
    During meiosis, the factors that control each trait separate and only one from each pair is passed to the offspring. This is known as the law of segregation, which was discovered by Mendel. This law explains how genetic information is passed from parents to offspring and how traits are inherited. It states that during the formation of gametes, the two alleles for each trait segregate or separate, so that each gamete carries only one allele for each trait. This ensures genetic diversity and variation in offspring.

    Area of a chromatid is exchanged with matching homologous chromosomes?

    • A.

      Crossing Over

    • B.

      Law of Segregation

    • C.

      Biodiversity

    Correct Answer
    A. Crossing Over
    Explanation
    Crossing over is the process in which genetic material is exchanged between homologous chromosomes during meiosis. This exchange occurs between chromatids, which are replicated copies of chromosomes. This process leads to genetic recombination and variation in offspring. Therefore, the area of a chromatid being exchanged with matching homologous chromosomes is a characteristic of crossing over. The other options, Law of Segregation and Biodiversity, do not involve the exchange of genetic material between chromatids.

    What era(s) did mammals supposedly evolve?

    • A.

      Mesozoic

    • B.

      Cenozoic

    • C.

      Mesozoic and Cenozoic

    • D.

      Unknown

    Correct Answer
    C. Mesozoic and Cenozoic
    Explanation
    Mammals supposedly evolved during both the Mesozoic and Cenozoic eras. The Mesozoic era, also known as the Age of Reptiles, spanned from about 252 to 66 million years ago and was characterized by the dominance of dinosaurs. It is believed that early mammals coexisted with dinosaurs during this era. The Cenozoic era, also known as the Age of Mammals, began about 66 million years ago after the extinction of dinosaurs and continues to the present day. This era saw the diversification and expansion of mammals into various ecological niches.

    What is the method used to solve a problem or do an experiment?

    • A.

      Classification Groups

    • B.

      Scientfific Method

    • C.

      Descriptive Data

    Correct Answer
    B. Scientfific Method
    Explanation
    The scientific method is a systematic approach used to solve problems or conduct experiments. It involves a series of steps including making observations, forming a hypothesis, conducting experiments, analyzing data, and drawing conclusions. This method allows researchers to gather reliable and valid information, ensuring that their findings are based on evidence and can be replicated by others. It is widely used in various fields of science to investigate and understand the natural world.

  • 5. 

    What is 6CO2+6H2O= C6H12O6+60

    • A.

      Chlorophyll

    • B.

      Adenine

    • C.

      Thymine

    Correct Answer
    A. Chlorophyll
    Explanation
    Chlorophyll is the correct answer because it is a pigment found in plants that is responsible for capturing light energy during photosynthesis. The equation given represents the process of photosynthesis, where carbon dioxide and water are converted into glucose and oxygen using light energy. Chlorophyll plays a crucial role in this process by absorbing light energy and initiating the chemical reactions that produce glucose, which is the main source of energy for plants.

    Fact of nature accepted by scientists is

    Correct Answer
    Scientific Law
    Theory
    Scientific Method
    Explanation
    Scientists accept both scientific laws and theories as facts of nature. A scientific law is a statement that describes a natural phenomenon or pattern in the physical world. It is based on repeated observations and experiments and is considered to be universally true. On the other hand, a scientific theory is a well-substantiated explanation of some aspect of the natural world. It is supported by a large body of evidence and has undergone extensive testing and peer review. The scientific method, although not a fact of nature itself, is the systematic approach that scientists use to acquire knowledge and understanding of the natural world.

    Rate this question:

  • 7. 

    Food quanity, Size of habitat, and more factors are part of __________, and it affects the population size and growth.

    • A.

      Carrying capacity

    • B.

      Biodiversity

    • C.

      Habitat Degradation

    Correct Answer
    A. Carrying capacity
    Explanation
    Carrying capacity refers to the maximum number of individuals of a species that can be supported by a given habitat. It takes into account various factors such as food quantity, size of habitat, and other limiting resources. As these factors change, the carrying capacity can also change, influencing the population size and growth. Therefore, carrying capacity is directly related to the factors mentioned and affects the population size and growth.

  • 8. 

    What are these? Amber, Trace, Mold, Cast, Imprint...

    • A.

      Types of Rocks

    • B.

      Types of Dinosaurs

    • C.

      Types of Fossils

    Correct Answer
    C. Types of Fossils
    Explanation
    The given words, such as amber, trace, mold, cast, and imprint, are all associated with the field of paleontology and the study of fossils. These words describe different types of fossils that can be found in the earth, providing evidence of ancient life forms. Therefore, the correct answer is "Types of Fossils."
