What comes after class in the classification system?
- A.
Kingdom
- B.
Phylum
- C.
Domain
- D.
Order
Correct Answer
D. OrderExplanation
In the classification system, organisms are grouped into different categories based on their characteristics. The correct answer is "order" because it is the category that comes after "class" in the hierarchical classification system. The classification system starts with the broadest category, which is "kingdom," and then becomes more specific as it progresses through "phylum," "class," and so on. "Order" is a more specific category than "class" and helps to further classify organisms based on similarities and differences.Rate this question:

A scientific name is typically written in this language.
- A.
Spanish
- B.
Latin
- C.
English
- D.
Russian
Correct Answer
B. LatinExplanation
Scientific names are typically written in Latin. This is because Latin is a dead language, meaning it is no longer spoken as a native language by any community. As a result, Latin remains unchanged over time and is universally understood by scientists around the world. Using Latin for scientific names ensures consistency and avoids confusion caused by different languages. Additionally, Latin provides a standardized system for naming organisms, allowing scientists to categorize and classify them accurately.Rate this question:

Italics
- C.
All capital letters
- D.
Superscript
Correct Answer
B. ItalicsExplanation
Scientific names are written in italics to distinguish them from common names and to indicate that they are in Latin or Latinized. This convention helps scientists and researchers to easily identify and recognize the specific species being referred to, regardless of the language being used. Additionally, italics visually set apart the scientific names from the surrounding text, making them stand out and facilitating their comprehension and accuracy in scientific literature.Rate this question:

When classifying organisms, scientists look at it's
- A.
Structure
- B.
Function
- C.
Both A and B
- D.
Neither A or B
Correct Answer
C. Both A and BExplanation
When classifying organisms, scientists consider both the structure and function of the organism. Structure refers to the physical characteristics and arrangement of the organism's body parts, while function refers to the roles and activities performed by those body parts. By examining both the structure and function, scientists can gain a comprehensive understanding of an organism's characteristics and how it interacts with its environment. This allows for more accurate classification and identification of organisms.Rate this question:

A dichotomous key gives:
- A.
2 descriptions for each step
- B.
3 descriptions for each step
- C.
4 descriptions for each step
- D.
Depends on how many individuals there are
Correct Answer
A. 2 descriptions for each stepExplanation
A dichotomous key gives 2 descriptions for each step. This means that at each step of the key, there are two options or characteristics given to help identify the organism or object being classified. By choosing the correct option at each step, the user can narrow down the possibilities and eventually arrive at the correct identification. Having two descriptions for each step allows for a more precise and systematic approach to classification.Rate this question:

What structure protects the virus?
- A.
DNA
- B.
Protein Coat
- C.
Tail
Correct Answer
B. Protein CoatExplanation
The correct answer is Protein Coat. Viruses are composed of genetic material, either DNA or RNA, surrounded by a protein coat called a capsid. This protein coat provides protection to the viral genetic material and helps in the virus's attachment to host cells. Additionally, some viruses may also have an outer envelope made of lipids, which further protects the virus. Therefore, the protein coat is essential for the survival and infectivity of the virus.Rate this question:

What part of the cell does a virus take over?
- A.
Chloroplast
- B.
Mitochondria
- C.
Lysosome
- D.
Nucleus
Correct Answer
D. NucleusExplanation
Viruses are intracellular parasites that require a host cell to reproduce. Once inside the host cell, a virus takes over the cell's machinery to replicate itself. The nucleus is the control center of the cell, containing the genetic material (DNA or RNA) that directs cellular activities. By taking over the nucleus, the virus hijacks the cell's genetic machinery, forcing it to produce viral components instead of performing its normal functions. Therefore, the correct answer is nucleus.Rate this question:

What part of the virus is injected into the cell?
- A.
DNA
- B.
Protein Coat
- C.
Tail
Correct Answer
A. DNAExplanation
When a virus injects its genetic material into a host cell, it is usually in the form of DNA. This DNA contains the instructions for the virus to replicate and take over the host cell's machinery to produce more viruses. The DNA is essential for the virus to hijack the cell's processes and ensure its own survival and reproduction. Therefore, the correct answer is DNA.Rate this question:

HIV:
- A.
Is the bacteria that causes AIDS
- B.
Is the virus that causes AIDS
- C.
Is something you get from tuberosity
- D.
Is the same as DNA
Correct Answer
B. Is the virus that causes AIDSExplanation
HIV is the virus that causes AIDS. AIDS is a condition that affects the immune system, and it is caused by the human immunodeficiency virus (HIV). HIV attacks and weakens the immune system, making it difficult for the body to fight off infections and diseases. It is primarily transmitted through unprotected sexual intercourse, sharing needles, or from mother to child during childbirth or breastfeeding. HIV is not a bacteria or the same as DNA, but rather a virus that specifically targets and damages the immune system.Rate this question:

What are two different forms of asexual reproduction?
- A.
Binary fission and budding
- B.
Binary fission and pollination
- C.
Pollination and budding
- D.
Transfusion and budding
Correct Answer
A. Binary fission and buddingExplanation
Binary fission and budding are two different forms of asexual reproduction. Binary fission is a process in which a single parent organism divides into two identical daughter cells. This is commonly observed in bacteria and other single-celled organisms. Budding, on the other hand, involves the formation of a small outgrowth or bud on the parent organism, which eventually detaches and develops into a new individual. This method is seen in organisms like yeast and hydra. Both binary fission and budding allow for the production of offspring without the need for fertilization or the involvement of another parent organism.Rate this question:
