Does peterson's solution to the mutual-exclusion problem shown in fig. 2-24 work when process scheduling is preemptive

1 answer:

4 0

Yes. Not only does Peterson's Solution work with preemptive scheduling, but it was designed for that very case. In fact, when scheduling is non-preemptive, there is a possibility it might fail. For example, in a case where 'turn' is initially 0, but process 1 runs first, it will loop perpetually, and never release the CPU.

Dandelions grow quickly and produce many seeds, ensuring that at least some plants will survive and produce seeds themselves. Wh

Pani-rosa [81]

Species strategies to survive and successfully reproduce define three basic survivorship curves. The survivorship curve type III is the one that best represents the Dandelion plants.

------------------------------

According to the species strategies to survive, reproduce, and ensure their reproductive success, we can mention three basic curves,

Type I.

Mortality often occurs at the end of the cycle, representing species with low mortality.

Organisms exhibiting this type of survivorship curve have long life cycles and high probabilities to survive until they are old enough.

These species have few descendants and spend too much time and energy in parental care to ensure their reproductive success.

Type II.

The probabilities of dying are equals all along the cycle, at any age interval.

The number of dead individuals remains constant from the beginning to the end of the life cycle.

These species have reduced offspring, and they ensure their reproductive success by providing some significant parental care.

Type III.

Significant mortality during the early stages of life.

Only a few individuals reach the later life stages, getting to survive their first period of life. Survivors usually have a long life.

These species produce large offspring at the same time, but they provide little or no parental care.

The reproductive success of these species depends on the number of descendants and not on the parenting time spent.

According to this information, and the characteristics of the Dandelions, we might assume that this species is represented by type III curve.

This is B; false.

Europe is not located in the tropics. In fact, no European countries lie in the tropical region. Europe is located in the temperate climate zone.

agasfer [191]

Cell division and differentiation first begins during the germinal stage of prenatal development.

Explanation:

The development of the zygote into a full developed fetus occurs in three most prominent stages they are the germinal stage that occurs from the conception to the second week.

The embryonic stage that is from second week to the eighth week and the fetal stage that is from the eighth week till the birth of the baby. Each stage has its characteristic development that has to be completed.
