I believe the correct answer is: True.

 

     The concentration of mercury in tropical fish is mostly in their liver, kidney and muscle, but there is the difference in level of concentration. Mercury levels of concentration have been shown to increase with size and age of the ingested fish, and within the species that occupy higher trophic levels.

Intersections are some of the most dangerous parts of the roadway. What factors cause them to be unsafe? How can driver actions
Tresset [83]

Answer:

What factors make intersections particularly dangerous?

This is part of the road where multiple paths intersect and drivers usually misjudge most situations associated with these paths and how they should proceed .

How can drivers actions reduce the dangers of intersection?

They need to follow every single road or driving procedures associated with intersections for example if a vehicle on your left reaches the intersection after you , you should continue driving but if it arrives first you must make sure that you yield .

When two vehicles arrives at the intersection simultaneously from different roads especially in an uncontrolled intersection where there are no stop signs or any road signs the one on the right has a right of way and the driver on the left need to yield .

Whether it is uncontrolled or controlled intersection drivers need to approach them with caution and not assume that the other drive will do that on their behalf .

Which statement about the life review is FALSE? a. It is sometimes simple nostalgia or reminiscence. b. It can be more social th
allsm [11]

Answer:

The correct answer is: d) Nostalgia represents a preoccupation with self that is meaningless and is evidence of egocentrism.

Explanation:

Life review refers to the universal mental process or inner experience that occur in elders or people who have near-to-death experiences and might be thought of as viewing a movie of the person's entire life as a reminiscence, contemplation or review. Becoming aware of our own mortality and vulnerability migh provoke stress, anxiety or depressive symptoms, while one comes to evaluate their journey in relation to others and to oneself.

Recent studies support the idea that evoking nostalgia has a positive effect on psychological well-being of people going through this process. Thus, nostalgia cannot be thought as meaningless. Furthermore, the oppposite is true: nostalgia can change the state of mind from negative to positive reminiscense.
