- C.
The kingdom protista are all the people who protest.
Correct Answer
A. The kingdom protista are single cellular EUKARYOTES.Explanation
The correct answer is "The kingdom protista are single cellular EUKARYOTES." This is because the kingdom Protista is a diverse group of eukaryotic organisms that includes both single-celled and multicellular organisms. They are characterized by having a true nucleus and other membrane-bound organelles. The statement that they are single cellular prokaryotes is incorrect, as prokaryotes do not have a nucleus or membrane-bound organelles. The statement about people protesting is unrelated and not a valid description of the kingdom Protista.Rate this question:
-
- 11.
How do protista move?
- A.

- B.
Protista use the bus.
- C.
Protista are stationary.
Correct Answer
A. The Protista use their false feet called pseudopods, their tail called flagellum or hair called cilia.Explanation
Protista are a diverse group of organisms that include single-celled organisms such as amoebas and paramecia. These organisms have different methods of movement. Some protista use pseudopods, which are temporary extensions of their cell membrane, to move by extending and retracting these false feet. Others have a tail-like structure called flagellum, which they use to propel themselves through water. Additionally, some protista have hair-like structures called cilia that beat in coordinated waves to move the organism. Therefore, the correct answer is that protista can move using their pseudopods, flagellum, or cilia.Rate this question:

- B.
Fungi use the thread-like cells of hyphae to branch out over large areas and reach the nutrients they need.
- C.
Fungi use the thread-like cells of hyphae to climb stairs to the kitchen so they can grab some lunch..
Correct Answer
B. Fungi use the thread-like cells of hyphae to branch out over large areas and reach the nutrients they need.Explanation
Fungi use the thread-like cells of hyphae to branch out over large areas and reach the nutrients they need. Hyphae are the main structural component of fungi and they allow fungi to extend and explore their environment in search of food. The branching nature of hyphae allows fungi to cover a larger surface area, increasing their chances of encountering and absorbing nutrients. This enables fungi to obtain the necessary resources for growth and reproduction.Rate this question:

Good Job, Penny, you have reached the half way point in this quiz. You can do it! Can viruses live on their own?
- A.
No. viruses are non-living chemicals that need a host cell to carry out life functions.
- B.
Yes. Viruses don't need a host cell. They can collonize just like fungi can.
- C.
No. Viruses are living things but need a host cell just like we need a house.
Correct Answer
A. No. viruses are non-living chemicals that need a host cell to carry out life functions.Explanation
Viruses are considered non-living because they lack the ability to carry out life functions on their own. They are essentially just genetic material (DNA or RNA) enclosed in a protein coat. In order to replicate and carry out their life cycle, viruses need to infect a host cell and hijack its cellular machinery. Without a host cell, viruses are unable to perform essential life processes such as metabolism, growth, and reproduction. Therefore, they are dependent on a host cell to carry out these functions.Rate this question:

- B.
A virus has both RNA and DNA genetic material that is covered by a protien coat called a capsid.
- C.
The virus has genetic material either of RNA or DNA, but not both. The genetic material is covered by a protein coat called a capsid.
Correct Answer
C. The virus has genetic material either of RNA or DNA, but not both. The genetic material is covered by a protein coat called a capsid.Explanation
The correct answer is that a virus has genetic material either of RNA or DNA, but not both. The genetic material is covered by a protein coat called a capsid. This is because viruses can either have RNA or DNA as their genetic material, but not both at the same time. The genetic material is protected and enclosed by a protein coat called a capsid.Rate this question:

How are visues classified?
- A.
BY size. Some viruses are very big compared to other viruses.
- B.
By colour. Viruses either have many colours or are black and white.
- C.
By geometrical shape. A cubic shape has many sides. A helical shape is like a spiral rod.
Correct Answer
C. By geometrical shape. A cubic shape has many sides. A helical shape is like a spiral rod.Explanation
Viruses are classified by their geometrical shape. This is because different viruses have distinct shapes, such as cubic or helical. A cubic shape has many sides, while a helical shape is like a spiral rod. By categorizing viruses based on their geometrical shape, scientists can better understand their structure and characteristics.Rate this question:

How do viruses infect host cells?
- A.
They ask bijou where the door is into the host cell.
- B.
Some viruses have a special tail that lets them grab onto the host cell. Other viruses have binding proteins to attach to the host cell.
- C.
Viruses are so small they can diffuse into the cell from lower concentration to higher concentration.
Correct Answer
B. Some viruses have a special tail that lets them grab onto the host cell. Other viruses have binding proteins to attach to the host cell.Explanation
Viruses infect host cells by either using a special tail to grab onto the host cell or by using binding proteins to attach to the host cell. This allows the virus to enter the cell and begin the process of replication and infection.Rate this question:
-

Can the same type of virus infect bacteria plants and animals?
- A.
No. A virus will infect only bacteria, only plants, or only animals but the same type of virus cannot infect all three.
- B.
Yes. The same virus will infect bacteria, plants and animals.
Correct Answer
A. No. A virus will infect only bacteria, only plants, or only animals but the same type of virus cannot infect all three.Explanation
The explanation for the given answer is that viruses have a specific host range, meaning they can only infect specific types of organisms. Bacteriophages are viruses that infect bacteria, plant viruses infect plants, and animal viruses infect animals. Each type of virus has specific receptors that can only bind to certain host cells. Therefore, it is not possible for the same type of virus to infect all three types of organisms.Rate this question:

How do viruses reproduce?
- A.
Viruses reproduce sexually.
- B.
Viruses reproduce asexually.
- C.
Viruses reproduce by using the host cell to make virus parts, put the virus parts together and release the new viruses.
Correct Answer
C. Viruses reproduce by using the host cell to make virus parts, put the virus parts together and release the new viruses.Explanation
Viruses reproduce by hijacking the machinery of host cells to replicate their own genetic material and assemble new virus particles. They do not have the ability to reproduce sexually, as they lack the necessary cellular machinery for meiosis or fertilization. Therefore, the correct answer is that viruses reproduce by using the host cell to make virus parts, assembling them, and releasing new viruses.Rate this question:

*phew* This is hard work. Keep going Penny. Just a few more questions. How do bacteria reproduce?
- A.
Bacteria reproduce sexually by creating a cytoplasmic tube between two bacteria.
- B.
Bacteria reproduce only in caves.
- C.
Bacteria reproduce asexually through binary fission. The genetic material doubles then a wall called a septum divides the two sets of genetic material. The bacteria then pinches in half becoming two new bacteria.
Correct Answer
C. Bacteria reproduce asexually through binary fission. The genetic material doubles then a wall called a septum divides the two sets of genetic material. The bacteria then pinches in half becoming two new bacteria.Explanation
Bacteria reproduce asexually through binary fission. This process involves the doubling of genetic material, followed by the formation of a wall called a septum that divides the two sets of genetic material. The bacteria then undergoes a process of pinching in half, resulting in the formation of two new bacteria. This method of reproduction does not involve the creation of a cytoplasmic tube or the requirement of caves.Rate this question:

How do bacteria share genetic material?
- A.
Bacteria share genetic material when they reproduce.
- B.
Bacteria share genetic material though conjugation by growing a cytoplasmic tube betweeen two bacteria, transduction when a virus spreads bacterial DNA and transformation when a bacteria absorbs environmental DNA.
- C.
Bacteria dont share genetic material.
Correct Answer
B. Bacteria share genetic material though conjugation by growing a cytoplasmic tube betweeen two bacteria, transduction when a virus spreads bacterial DNA and transformation when a bacteria absorbs environmental DNA.Explanation
Bacteria share genetic material through three main processes: conjugation, transduction, and transformation. Conjugation involves the growth of a cytoplasmic tube between two bacteria, allowing for the transfer of genetic material. Transduction occurs when a virus spreads bacterial DNA, transferring genetic material between bacteria. Transformation happens when a bacteria absorbs environmental DNA, incorporating it into its own genetic material. These processes enable bacteria to exchange genetic material and contribute to genetic variation within bacterial populations.Rate this question:

- C.
Lag, log, stationary and decine phase.
Correct Answer
C. Lag, log, stationary and decine phase.Explanation
The correct answer is "Lag, log, stationary and decline phase." This answer accurately describes the four stages of bacteria growth. The lag phase is the initial period of adjustment and preparation for growth. The log phase is the period of rapid exponential growth. The stationary phase is when the growth rate slows down and the number of bacteria stabilizes. The decline phase is when the bacteria start to die off due to lack of resources or accumulation of waste products.Rate this question:
