    Which structure protects the virus?

    • DNA

    • Protein Coat

    • Tail

    Correct Answer
    A. Protein Coat
    Explanation
    The protein coat, also known as the capsid, is a protective structure that surrounds the genetic material of a virus. It provides stability and protection to the virus, shielding it from the external environment and host immune system. The protein coat plays a crucial role in the virus's ability to infect host cells and replicate. It helps in the attachment and entry of the virus into the host cell, as well as in the release of the viral genetic material into the host cell's cytoplasm. Therefore, the protein coat is essential for the survival and infectivity of the virus.

    A scientific name is typically written in this language:

    • Spanish

    • Latin

    • English

    • Russian

    Correct Answer
    A. Latin
    Explanation
    Scientific names are typically written in Latin. This is because Latin is a dead language that is no longer evolving, making it a stable and consistent language for naming organisms. Latin also has a long history in the field of science, particularly in taxonomy, and many scientific terms and naming conventions are based on Latin. Using Latin for scientific names ensures that they are universally understood and avoids confusion caused by different languages.

    HIV:

    • Is the bacteria that causes AIDS.

    • Is the virus that causes AIDS.

    • Is something you get from tuberosity

    • Is the same as DNA

    Correct Answer
    A. Is the virus that causes AIDS.
    Explanation
    The correct answer is "is the virus that causes AIDS." HIV (Human Immunodeficiency Virus) is a retrovirus that attacks the immune system, specifically the CD4 cells (T cells), leading to a weakened immune system and making the person more susceptible to infections and diseases. AIDS (Acquired Immunodeficiency Syndrome) is the advanced stage of HIV infection. It is important to note that HIV is not a bacteria, and it is not the same as DNA.

    HIV attacks:

    • Digestive system

    • Immune system

    • Respiratory system

    • Circulatory system

    Correct Answer
    A. Immune system
    Explanation
    HIV attacks the immune system. This is because HIV specifically targets and infects CD4 cells, which are a type of white blood cell that plays a crucial role in the immune response. By infecting and killing CD4 cells, HIV gradually weakens the immune system, making the body more susceptible to opportunistic infections and diseases. This is why people with HIV are at a higher risk of developing severe infections and illnesses, as their immune system is compromised.

    What an organism looks like or the parts that it has.

    • Structure

    • Function

    Correct Answer
    A. Structure
    Explanation
    The question is asking for the term that describes what an organism looks like or the parts that it has. The term that best fits this description is "Structure". Structure refers to the physical appearance and arrangement of the different parts of an organism. It includes the shape, size, and composition of these parts. Understanding the structure of an organism is important in determining its function and how it interacts with its environment.

    When a person yells, "Boo," and another person jumps, this is an example of:

    • Made of cells

    • Breathe oxygen

    • Response to stimuli

    • Reproduction

    Correct Answer
    A. Response to stimuli
    Explanation
    When a person yells "Boo" and another person jumps, it is an example of a response to stimuli. The loud sound of the yell acts as a stimulus, triggering a quick and involuntary reaction in the person who jumps. This response is a natural reflex that occurs in order to protect oneself from potential danger or threat.

    When classifying organisms, scientists look at their:

    • Structure

    • Function

    • Both A and B

    • Neither A or B

    Correct Answer
    A. Both A and B
    Explanation
    When classifying organisms, scientists consider both their structure and function. Structure refers to the physical characteristics and features of an organism, such as its body shape, organs, and tissues. Function, on the other hand, refers to the role or purpose that these structures serve in the organism's survival and reproduction. By examining both the structure and function of organisms, scientists can gain a comprehensive understanding of their characteristics and relationships, which helps in their classification and study.

    A bird has the ability to fly is an example of:

    • Structure

    • Function

    Correct Answer
    A. Function
    Explanation
    The statement "A bird has the ability to fly" describes the function of a bird. Function refers to the purpose or role of a particular characteristic or behavior in an organism. In this case, the ability to fly is a defining characteristic and purpose of a bird, allowing it to move through the air. The statement does not describe the structure or physical makeup of a bird, but rather focuses on what it can do.

    What is the correct order of virus invasion?

    • Attachment, replication, rupture, injection

    • Attachment, rupture, injection, confusion

    • Attachment, injection, replication, rupture

    • Injection, replication, rupture, attachment

    Correct Answer
    A. Attachment, injection, replication, rupture
    Explanation
    The correct order of virus invasion is attachment, injection, replication, and rupture. First, the virus attaches itself to the host cell. Then, it injects its genetic material into the host cell. After that, the viral genetic material takes control of the host cell's machinery and starts replicating itself. Finally, the host cell bursts open or ruptures, releasing the newly replicated viruses to infect other cells.

    What part of the cell does a virus take over?

    • Chloroplast

    • Mitochondria

    • Lysosome

    • Nucleus

    Correct Answer
    A. Nucleus
    Explanation
    A virus takes over the nucleus of a cell. Once inside the cell, the virus releases its genetic material, which then enters the nucleus. The virus then uses the cell's machinery to replicate its genetic material and produce more virus particles. By taking over the nucleus, the virus is able to manipulate the cell's normal functions and use its resources to reproduce and spread.

    What comes after class in the classification system?

    • Kingdom

    • Phylum

    • Domain

    • Order

    Correct Answer
    A. Order
    Explanation
    In the classification system, organisms are categorized into different levels. After class, the next level is order. This means that organisms within the same class are further divided into smaller groups called orders. The order level helps to provide more specific information about the characteristics and relationships of organisms within a particular class.

    A scientific name is written in:

    • Bold letters

    • Italics

    • All capital letters

    • Superscript

    Correct Answer
    A. Italics
    Explanation
    Scientific names are written in italics to differentiate them from common names and to adhere to the standard naming conventions in scientific literature. Italicizing the scientific name helps to clearly identify and distinguish the genus and species names from the rest of the text, making it easier for researchers and readers to recognize and refer to specific organisms. Additionally, italics also indicate that the name is a Latin or Latinized binomial, further emphasizing its scientific nature.

    What are two different forms of asexual reproduction?

    • Binary fission and budding

    • Binary fision and pollination

    • Pollination and budding

    • Tranfusion and budding

    Correct Answer
    A. Binary fission and budding
    Explanation
    Binary fission and budding are two different forms of asexual reproduction. In binary fission, a single organism divides into two equal-sized offspring, each with a complete set of genetic material. This process is commonly seen in bacteria and some single-celled organisms. On the other hand, budding involves the formation of a small outgrowth, or bud, on the parent organism. This bud eventually grows and develops into a genetically identical offspring, which detaches from the parent. Budding is observed in organisms such as yeast and hydra.

    What part of the virus injected in the cell

    • Tail

    • DNA

    • Protein Coat

    Correct Answer
    A. DNA
    Explanation
    The correct answer is DNA. When a virus infects a cell, it injects its genetic material, which is typically in the form of DNA, into the host cell. This DNA then hijacks the cellular machinery to replicate itself and produce new viral particles. The protein coat of the virus, also known as the capsid, helps protect the viral DNA and assists in the process of infecting new cells. However, it is the viral DNA that carries the genetic instructions necessary for the virus to replicate and cause infection.

    A dichotomous key gives:

    • 2 descriptions for each step.

    • 3 descriptions for each step.

    • 4 descriptions for each step.

    • Depends on how many individuals there are

    Correct Answer
    A. 2 descriptions for each step.
    Explanation
    A dichotomous key gives 2 descriptions for each step. This means that at each step of the key, there are two options or characteristics described that help to identify the organism or object being classified. These descriptions are usually presented in a series of paired statements or questions, with each option leading to a further set of descriptions until the final identification is made. This method of classification is commonly used in biology and other fields to identify and categorize organisms based on their characteristics.

    • Domain, Classs, Phylum, Kingdom,Order, Family, Genus, Species

    • Domain, Kingdom, Phylum, Class,Order, Family, Species, Genus

    Correct Answer
    A. Domain, Kingdom, Phylum, Class,Order, Family, Genus, Species
    Explanation
    The correct answer is Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species. This is the correct order of the hierarchical classification system used in biology to categorize organisms. The domain is the highest level, followed by the kingdom, phylum, class, order, family, genus, and species. This system helps organize and classify organisms based on their evolutionary relationships and shared characteristics.

    Which is not a characteristic of life?

    • They are made of cells

    • Move

    • Reproduce

    • Respond to stimuli

    • Breathe oxygen

    Correct Answer
    A. Breathe oxygen
    Explanation
    The characteristic "Breathe oxygen" is not a characteristic of life because not all living organisms require oxygen for survival. Some organisms, such as anaerobic bacteria, can survive and carry out their life processes without the presence of oxygen. Therefore, breathing oxygen is not a universal characteristic of all living organisms.
