Answer: The program completed in a quarter of the time with four computers versus one computer
Explanation:
Distributed computing simply means using distributed systems in solving computational problems and this is done as the problem is divided into many tasks, whereby the tasks are accomplished by one or more computers.
Following the information given in the question, a speedup of 4 indicate that the program completed in a quarter of the time with four computers versus one computer.
Answer: A vascular bundle is a part of the transport system in vascular plants. A strand of conducting vessels in the stem or leaves of a plant, typically with phloem on the outside and xylem on the inside.

The natural water sample contains only one type of bacteria.
A mutagenic agent is any chemical, physical or biological compost that can induce a mutation in the cell's DNA, making this mutation pass to the next generation.
Mutagenic agents are widely used in the fields of biotechnology, genetic engineering, medicine and agroindustry. This is because these agents have helped in the advancement and development of new technological tools.
In genetic research some bacteria and viruses are used by agribusiness companies to obtain transgenic beings. These mutagenic (biological) agents act as vectors of laboratory-created genes that will insert these genes into an organism to be modified. It could be, for example, a gene that will improve maize resistance against a pest. Thanks to mutagenic agents, this genetic information can be passed on to the organism, in this case, the plant.
Answer:

point mutation, change within a gene in which one base pair in the DNA sequence is altered. Point mutations are frequently the result of mistakes made during DNA replication, although modification of DNA, such as through exposure to X-rays or to ultraviolet radiation, also can induce point mutations
