Which of the following statements about viruses and bacteria is correct?
- A.
Both viruses and bacteria are living organisms.
- B.
Viruses are smaller than bacteria.
- C.
Both viruses and bacteria can be treated with antibiotics.
- D.
Viruses can reproduce independently, while bacteria require a host cell.
Correct Answer
B. Viruses are smaller than bacteria.Explanation
Viruses are significantly smaller than bacteria. They are typically measured in nanometers, while bacteria are measured in micrometers. This size difference reflects their fundamental structural differences: viruses are simple particles consisting of genetic material and a protein coat, while bacteria are single-celled organisms with a more complex cellular structure.Rate this question:

How does bacteria move?more then one answer
- A.
Move by rushing fluid
- B.
Move by flagellum
- C.
By attaching itself to cells
Correct Answer(s)
A. Move by rushing fluid
B. Move by flagellumExplanation
Bacteria can move in multiple ways. One way is by rushing fluid, where they use the flow of liquid to propel themselves forward. Another way is through the use of flagella, which are whip-like structures that rotate and allow bacteria to swim. These two mechanisms enable bacteria to move efficiently and explore their environment.Rate this question:

How does bacteria get transmitted?
- A.
Hands
- B.
Insects
- C.
Cold weather
- D.
Microwaved food unproperly
Correct Answer(s)
A. Hands
B. Insects
D. Microwaved food unproperlyExplanation
Bacteria can be transmitted through various means, including hands, insects, and improperly microwaved food. Hands can easily pick up bacteria from contaminated surfaces and transfer them to other objects or people through touch. Insects, such as flies or cockroaches, can carry bacteria on their bodies or in their digestive systems, spreading them when they come into contact with food or surfaces. Improperly microwaved food can also harbor bacteria if it is not heated to a high enough temperature to kill them. Therefore, all three options mentioned in the answer can contribute to the transmission of bacteria.Rate this question:

How does a virus reproduce?
- A.
With a female virus
- B.
By controlling a cell to make copies
- C.
They cant reproduce
Correct Answer
B. By controlling a cell to make copiesExplanation
Viruses reproduce by taking control of a host cell and using its machinery to produce more copies of themselves. They inject their genetic material into the host cell, which then follows the virus's instructions to create new viral components. These components are assembled into complete viruses, which are released from the host cell to infect other cells and continue the cycle of reproduction. This process allows viruses to spread and cause infections in living organisms.Rate this question:

Unlike bacteria, viruses cannot reproduce on their own and require a __________ cell to replicate.
Correct Answer
Host, hostExplanation
Viruses are essentially genetic material (DNA or RNA) enclosed in a protein coat. They lack the cellular machinery necessary for independent reproduction. To replicate, viruses must infect a living host cell and hijack its machinery to produce new viral particles. This dependence on a host cell is a key distinction between viruses and bacteria, which can reproduce independently through processes like binary fission.Rate this question:

An heterotroph is a bacteria which gets its energy from
Correct Answer
autotrophs
eatingExplanation
Heterotrophs are organisms that cannot produce their own food and rely on consuming other organisms for energy. In this case, the bacteria mentioned is a heterotroph that obtains its energy by consuming autotrophs. Autotrophs, on the other hand, are organisms capable of producing their own food through processes like photosynthesis. Therefore, the bacteria in question obtains its energy by feeding on autotrophs.Rate this question:

How does a virus get energy?
- A.
It produces energy
- B.
From host cell
- C.
They dont need it
Correct Answer
B. From host cellExplanation
A virus gets energy from the host cell because it lacks the necessary cellular machinery to produce energy on its own. Once inside a host cell, the virus hijacks the cell's metabolic processes and utilizes its resources to replicate and produce new viral particles. This energy acquisition from the host cell is crucial for the virus's survival and propagation within the host organism.Rate this question:

How does bacteria get energy
- A.
They dont need it
- B.
Binary fission
- C.
Conjuction
- D.
Mitosis
Correct Answer(s)
B. Binary fission
C. ConjuctionExplanation
Bacteria obtain energy through a process called binary fission, which is a form of asexual reproduction. During binary fission, a single bacterium divides into two identical daughter cells. This process allows bacteria to multiply and increase their population. Conjugation, on the other hand, is a method of genetic exchange between bacteria, but it does not directly provide them with energy. Mitosis is a process that occurs in eukaryotic cells, not bacteria, where a single cell divides into two identical daughter cells.Rate this question:
