Why is it difficult to avoid a tsunami?
Gelneren [198K]

Answer:

It is difficult to avoid a tsunami due to it being such a large volume of water that is capable of destroying a large amount of land.

Explanation:

However, even though it is difficult to avoid a tsunami, as they are extremely difficult to predict, there are ways where one can begin to prepare before it hits. One of the ways you can do this is getting to a higher ground far away from inland, avoiding downed power lines, and steering clear of buildings or bridges where large, heavy objects could fall during an aftershock.

Tsunamis are incredibly dangerous, since there is a great chance that if you get caught in one, you can drown. Since tsunamis have little to no warning when they arrive, it is always essential to be prepared when one strikes.

I hope this helped! :)

This food web represents a community in a rain forest.
kolbaska11 [484]

Answer:

coatis would increase

sloths would increase

fruit bats would increase

Explanation:

The boa constrictor in this food chain is the top predator, thus it is on the top of the food chain. It preys on several of the animals on this list, such as the coati, sloth, and fruit bats, so it is regulating their numbers. If the boa constrictor is removed from the ecosystem, the ecosystem will lose its predator, so the animals on which the boa constrictor preyed upon will have no threat, thus will experience rapid increase in their numbers. The coatis, sloths, and fruit bats, all will be predator free in this scenario, so they will all experience increase in their population, which in turn will have big effect on all other species in the ecosystem.

AysviL [449]

<u>Answer:</u>

Jack is correct because a solution is not a type of mixture because the substances stay mixed together and cannot be separated. Each substance loses its primary physical properties.

Option: (D)

<u>Explanation: </u>

  • A mixture is composed of 'two or more different substances', physically combined and it is in the form of a solution, suspension or a colloid.
  • A mixture may be homogeneous (salt and water) or heterogeneous (sand and water).
  • A homogeneous mixture of two or more compounds is termed as solution. It has a solute and a solvent.
  • The 'solute' is the substance dissolved in the solvent. Both lose their primary physical properties.
