    Substances pass in and out of a cell through the:

    • Cell membrane

    • Nuclear membrane

    • Mitochondria

    • Nucleus

    Correct Answer
    A. Cell membrane
    Explanation
    The cell membrane is responsible for regulating the movement of substances in and out of the cell. It is selectively permeable, allowing certain molecules to pass through while blocking others. This process, known as cellular transport, is essential for maintaining homeostasis and ensuring that the cell receives necessary nutrients and gets rid of waste products. The nuclear membrane surrounds the nucleus and controls the movement of molecules in and out of the nucleus, while the mitochondria are responsible for energy production. Therefore, neither the nuclear membrane nor the mitochondria are primarily involved in the movement of substances in and out of the cell.

    • A control

    • Multiple trials

    • A reproducible prodedure

    • Small sample size

    Correct Answer
    A. Small sample size
    Explanation
    A well-designed experiment should include a control group to compare the results, multiple trials to ensure accuracy and reliability, and a reproducible procedure to ensure that the experiment can be replicated by others. However, a small sample size is not a part of a well-designed experiment because it may not provide enough data to draw valid conclusions and increases the risk of obtaining biased or unreliable results. A larger sample size is generally preferred to increase the statistical power and representativeness of the experiment.

    The part of the cell that normally contains its genetic material is the:

    • Cell membrane

    • Nuclear membrane

    • Organelle

    • Nucleus

    Correct Answer
    A. Nucleus
    Explanation
    The nucleus is the part of the cell that normally contains its genetic material. It is responsible for controlling the cell's activities and contains the DNA, which carries the instructions for the cell's functions and characteristics. The nucleus is surrounded by a nuclear membrane, which separates it from the rest of the cell. The cell membrane, on the other hand, forms the outer boundary of the cell and regulates the movement of substances in and out of the cell. While organelles are specialized structures within the cell, they do not typically contain the genetic material.

    The offspring of asexual reproduction is identical to the parent except when there is:

    • A clone

    • A genetic mutation

    • Fertilization

    • Multicellular organisms

    Correct Answer
    A. A genetic mutation
    Explanation
    In asexual reproduction, offspring are typically identical to the parent because they are produced through mitosis, which creates exact copies of the parent's genetic material. However, a genetic mutation can occur during the replication process, leading to a change in the offspring's genetic material. This mutation can result in variations in the offspring's traits, making it different from the parent. Therefore, a genetic mutation is the only factor mentioned in the options that can cause the offspring of asexual reproduction to be different from the parent.

    Most human cells have ____ copies of each chromosome?

    • 10

    • 4

    • 2

    • 25

    Correct Answer
    A. 2
    Explanation
    Most human cells have 2 copies of each chromosome. This is because humans have a diploid number of chromosomes, meaning that each cell contains two sets of chromosomes, one set inherited from each parent. These chromosomes carry the genetic material that determines our traits and characteristics. Having two copies of each chromosome allows for genetic diversity and ensures that the necessary genetic information is present for proper cell function and development.

    The dominant condition of a characteristic is represented by:

    • RR, Rr, and rr

    • RR and Rr

    • RR and rr

    • Rr and rr

    Correct Answer
    A. RR and Rr
    Explanation
    The dominant condition of a characteristic is represented by RR and Rr because in genetics, uppercase letters represent dominant alleles, while lowercase letters represent recessive alleles. When an individual has at least one uppercase letter (R) in their genotype, it means they have the dominant allele and will express the dominant trait. Therefore, individuals with genotypes RR and Rr will both exhibit the dominant condition.
