-In Africa savanna more wildebeest are born than the environment can support. As a result over a period of years individuals that are well suited to the environment reproduce, and those that have lesser adaptations die before they reproduce. This is referred to as natural selection.
Answer:
The correct answer is option - e. all of the above are useful traits.
Explanation:
A cloning vector is a small segment of DNA that can be established stably in an individual organism and able to internalize a foreign DNA for cloning purposes. The cloning vector could be taken from different organisms such as plasmid of a bacterium, or DNA from a virus. A cloning vector must possess some characteristics -
The cloning vector must be self-replicating ability in the host cells, it should be small in size with restriction site for the restriction endonuclease enzymes in it. The replication character of the vector should not interfere with the internalized DNA fragment. The presence of marker genes in the vector is also a property that is helpful in identifying of recombinant cells.
Thus, the correct answer is option - e. all of the above are useful traits.
A: provided structural support to the cell
Answer:
Hantavirus pulmonary syndrome refers to a contagious disease featured by the flu-like signs, which can advance briskly to the possibly life-threatening inhalation issues. Many kinds of hantaviruses can lead to the syndrome. Many kinds of rodents can act as the vector for the virus, however, it is primarily caused by the deer mouse.
One can get infected with the condition mainly by inhaling air infested with hantaviruses, which are shed in the droppings and urine of the rodent. The scientists can assist in controlling the condition by offering ways to monitor the population of rodents. As the treatment choices are confined, the best defense against the condition is to prevent rodents and their territories.
