The expiratory flow sensor must read 3 L/min flow to trigger inspiration.
Given,
Base - Trigger or 5-2 = 3 L/min
Influence of Ventilator factors on affected person effort or work of breathing. The triggering segment—that is, from the onset of patient effort to onset of waft shipping—contains the cause variable of a mechanical breath.
Flow triggering is a popular method for allowing patients to initiate breaths in the course of mechanical ventilation. It works via putting a non-stop “background flow” of gas through the ventilator circuit in the course of expiration referred to as Bias flow.

Answer:
C) Some individual insects are more likely than others to survive and reproduce due to their inherited traits.
Explanation:
Insects are known for their ability to develop resistance to insecticides. Currently there are insects resistant to every synthetic chemical insecticide used. There are many factors to developing resistance, for example:
- many insects species produce large broods. This increases the probability of mutations and ensures the rapid expansion of resistant populations.
- Insects with shorter life times develop resistance more quickly than others because its genetics make them reproduce much faster.
- insects with limited diets are more likely to evolve resistance, because they are exposed to higher pesticide concentrations and has less opportunity to breed with unexposed populations.
But this kind of phenomenon has not only observed in insects in England, rats in certain areas have evolved resistance that allows them to consume up to five times as much rat poison as normal rats without dying.

It is the time when they start to question their environment about the importance of her feelings and how to interact with them. Also, their hormones are two compared to boys which has only one.</span>

The correct answer is:
Robert House's Path-Goal theory
Explanation:
This theory was proposed by Robert House in 1971 in his paper A Path-Goal Theory of Leader Effectiveness, in which he proposes that the main role of a good leader is to motivate the whole group by different techniques according to the situation. According to House, there are some cases in which it is better to focus on the leader's purposes and sometimes it is better to focus on the groups' purposes. According to this concept, he classified the different situations as:
1 - democratic - motivation of the group due to the crew's goals
2 - autocratic - motivation of the group because of the leader's goals
3 - Laissez-faire - the leader is not interested in making efforts towards the goals, he just let the circumstances to go on.
