Answer:
Explanation:
Molecules within a liquid are pulled in all directions by intermolecular forces; there is no tendency for them to be pulled in any one way. However, molecules at the surface are pulled downward and sideways by other molecules, but not upward away from the surface. These intermolecular attractions thus tend to pull the molecules into the liquid and cause the surface to tighten like an elastic film.
A measure of the elastic force in the surface of a liquid is surface tension. The <em>surface tension</em><em> is the amount of energy required to stretch or increase the surface of a liquid by a unit area</em>. Surface tension enables small insects, like the water strider, to “walk” on water.
The correct answer should be B) tracheae to distribute oxygen
The remaining options aren't found in both groups of life forms.
Answer: An intact coastal wetland
Explanation:
Hurricane storm surges results when the water level rises above normal as a result of a storm and therefore goes inland from the coast far deeper than it normally does.
Normally this can destroy things next to the coast by washing them away but some ecosystem services can provide protection against this such as an intact coastal wetland. Being intact, there are less chances of being washed away and as it is a wetland it is used to high levels of water and can even absorb some of the surge.
<h2>prokaryotes (which include bacteria) undergo a type of cell division known as binary fission. </h2>
Answer:
false
Explanation:
Autotrophs, organisms that produce their own food, are the first trophic level. These include plants and algae. Herbivores, which eat autotrophs, are the second trophic level. Carnivores, organisms that consume animals, and omnivores, organisms that consume both plants and animals, are the third trophic level.
