The african snail is a large snail that eats at least 500 different types of plants and is one of the top 100 invasive species in the world. how was the snail introduced into florida?

a. a small animal was carrying one on its fur.
b. a boy brought a pair home as pets.
c. two swam across the ocean.
d. one stuck to an airplane’s wing.

Answer : Option B) A boy brought a pair home as pets.

Explanation : As snails are very small organisms which can hardly travel distances. So, it is not valid that the snails swam across the ocean.

If it got stuck on an airplane's wing it might get pushed away by the high pressure of air during flight.

The most legitimate and probable answer seems to be that, A boy who had visited Africa purchases the pair as pets and brought them to Florida

chlorophyll a: this is the most abundant pigment in plants. chlorophyll a absorbs light with wavelengths of 430nm(blue) and 662nm(red). it reflects green light strongly so it appears green to us.

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.
