How can natural selection account for the long snout of an anteater ?
djyliett [7]
First of all, the purpose of natural selection is to "weed out" the organisms in a species with imperfect qualities.  Basically, it's evolution's way of making the species that best it can be.

An anteater eats insects (namely, ants) by sticking its snout and tongue through anthills and the ground.  Obviously, the longer the snout of the anteater, the more possible bugs it can reach and, therefore, eat.  So, over millions of years, anteaters with shorter snouts were not able to reach enough bugs and ended up dying.  The anteaters with longer snouts had more food available because they could reach more bugs, so they were able to live long enough to reproduce and produce offspring with the preferred trait:  having a longer snout.

How does sulfur in the air get moved to the soil.
Andrew [12]

Answer:

Sulfur can also fall directly from the atmosphere in a process called fallout. Also, the weathering of sulfur-containing rocks releases sulfur into the soil. These rocks originate from ocean sediments that are moved to land by the geologic uplifting of ocean sediments.

When pouring food coloring into warm water and cold water, we can see that the
svet-max [94.6K]

Answer:

true!!

Explanation:

the faster molecules move, the warmer the object is. think of how much energy you feel when you touch hot water and you whip your hand back, thats similar to how the molecules are movin, all that heat is energy built up in them and theyre moving around all crazy haha. Then think of putting ice in the freezer, all the molecules are kinda frozen in place, all squished together, because they dont have enough energy to move around. so, when the hot molecules with all that energy are moving around, the food coloring is able to get all over in the water. Kind of like if youre on a road trip the faster you drive the faster you'll get places. if you drive super slow, then it'll take forever to get there. so true, when food coloring is dropped into faster hotter molecules, it will spread faster. :)
