A truck whose bed is 2.5 m long 1.5 m wide and 1.0 m high is delivering sand for sand sculpture competition. About how many trips must the truck make to deliver 7m of sand

Answers

Assuming you mean 7m^3 (meters cubed) of Sand:
Volume = base x width x height
The truck can hold a volume of 2.5 x 1.5 x 1 = 3.75 m^3.
To move 7 m^3 of sand, the truck will have the make two trips. The first trip, the truck will move 3.75 m^3 of sand, and on the second, it will move 7-3.75=3.25 m^3.

50 POINTS PLZ QUESTION ABOUT HURRICANE FLORENCE Where did the storm cause the greatest shoreline erosion? (Think east or west of the hurricanes path) explain your answer using what you know about the rotation of the hurricane.

It was west in Florence It was like the biggest dangerous hurricane that is why here in the united states has been dark these couple of days and still is. the rotation has gone west but the hurricane is not to dangerous right now because all the rain drops had to be low because there was already too much rain in the west and rotated to the south but more in the west.

Describe the effects of man on the ecosystem with emphasis on examples of international importance (tropical rainforests)

Answers

Answer:

Human activities have adversely affected the ecosystem because human needs wood for making houses so they cut the trees and the organisms lives there loss their habitat and whole ecosystem is disturbed. Tropical forest is also called lungs of planet earth because they provide oxygen to the atmosphere and absorbs carbondioxide gas in large amounts. About half of world species lives in these forest. If humans continue to cut these forest all the species lives their will be vanished and affected the whole world.

Apple farmers are currently having a very difficult time with pesticide-resistant insects. These insects are no longer being killed by the current chemical treatments, thus causing a lot of damage to the apple crops. In reaction to this, researchers are developing newer and stronger chemicals to help control the bugs. Why are the apple farmers seeing these new, stronger bugs?

Answers

The right answer is that a strongest bugs were able to survive pesticides, reproduce and create more resistant pests.

Pesticide resistance is a hereditary trait that gives an organism the ability to survive pesticide application at lethal doses for most individuals of the same species.

This resistance, manifested by the absence of inhibition, or reduced inhibition, of the development of a population of pests, may be natural or acquired.

* It is natural if the phenomenon is observed from the first application of a pesticide.

* It is called "acquired" if the phenomenon is observed only after several applications of a pesticide, as a result of the selection over several generations of naturally resistant individuals.

Harmful species develop resistance to pesticides through natural selection: the most resistant specimens survive and transmit their genetic traits to their offspring.

The farmers are seeing stronger bugs because not all bugs die to the amount of pesticide. Some areas are not spreaded evenly or some bugs are more resistant genetically. The ones that are not killed by the pesticide reproduce and pass that trait onto other bugs. One into ten, ten into hundred, etc. This makes the current pestcide useless and the need to find a stronger or different pesticide. This is why some farmers rotate crops and pestcide used.
