What is the function of restriction endonucleases in bacteria? View Available Hint(s) What is the function of restriction endonucleases in bacteria? They serve no function. They allow bacteria to genetically recombine with other bacteria. They allow bacteria to engineer new DNA fragments. They provide a defense mechanism against infection by viruses.

They provide a defense mechanism against infection by viruses.

Explanation:

They are the natural enzymes of bacteria, which they use for their own protection against viruses. The restriction enzymes cut down the viral DNA, but does not harm to the bacterial chromosome. They are called restriction enzymes because they restrict the growth of virus.

gregor john mendel is known for study of inheritance in pea plants. he used garden pea plant for his study, having alternative traits for various characters. he performed cross-breeding in pea plants to check how characters are transmitted between parents to offspring, such as cross between pure tall and pure dwarf plant. mendel studied the inheritance patterns in pea plants for various generations.

thus, the correct answer includes options and f).

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
