Answer:
The virus will transfer the DNA encoding cholera toxin to the next bacteria it infects, which will make that bacteria cholera-causing.
Explanation:
The process described in this question is a kind of gene transfer in bacteria called TRANSDUCTION. Transduction is the transfer of fragments of DNA from one bacterium to another via a virus called bacteriophage.
As stated in this question, the virus (bacteriophage) infects a cholera-causing bacterium. The bacteriophage moves from lysogenic cycle to lytic cycle and includes some pieces of the bacterial DNA, which encodes information for making the cholera toxin, in its own genome.
This means that the cholera-making toxin DNA is now a part of the virus's genome and hence, will transfer it to the next bacteria it infects in a process called TRANSDUCTION. This will make that bacteria a cholera causing bacteria.
D. descriptive investigations
Explanation:
A scientist studying the star Alpha Centauri would probably rely on descriptive investigation to gather data.
In descriptive investigation, experiments cannot be performed since the subjects cannot easily be manipulated or they are far too inaccessible. This form of investigation is based on indirect qualitative investigation of a phenomenon.
- Alpha Centauri is a distant star several light years away from the vicinity of the scientist.
- The best way to investigate this distance body is to make inferences from the evidence gathered from observatory stations using telescopes.
- Astronomers can collect different information and give vivid description of the distant start.
- It is highly impossible to make comparisons and alter variable in this kind of investigation.

Operational risk management is a continual cylic process that involves assessment of risk, risk decision making and execution of risk controls. it is a five step process and it is often used in planning. the five steps include identifying the hazard. hazard is anything with the potential of causing harm. the second step is assessment of hazard. this is followed by making risk decisions and fourth step execution of risk controls and finally supervision.
Answer:
<em>Staphylococcus aureus</em>
Explanation:
According to the rule of binomial nomenclature, the name of the organism is written in two parts that are-
1. Generic name- The first name which signifies the genus of the organism, the word represents the noun of the organism, the first letter of the word is always uppercase that is like in the "Staphylococcus"
2. The specific epithet-the second name of the organism represents the species which is usually a noun, and the first letter of species is always written in lowercase like in the aureus.
The scientific name should be written either in the italicised form or if not possible to write in the italicised form than underline the name.
Thus, <em>Staphylococcus aureus </em>is correct.
Answer:
The typical story of reproduction is that males and females of an animal species do it sexually. Generally, that's what honeybees do, too. Sperm from a male drone fertilizes a queen's eggs, and she sends out a chemical signal, or pheromone, that renders worker bees, which are all female, sterile when they detect it.
Explanation:
In the Cape bee, female worker bees are able to reproduce asexually: they lay eggs that are essentially fertilized by their own DNA, which develop into new worker bees. The team sequenced the entire genomes of a sample of Cape bees and compared them with other populations of honeybees that reproduce normally
