Which of the following would best explain why a species of wildflower native to Switzerland is observed growing in the wild Montana?
A.Water dispersed seeds of the wildflower.
B.Water dispersed seeds of the wild flower.
C.An animal ate seeds and later dispersed them.
D.A human brought and dispersed the seeds.
My answer is B is this right.
sorry A is Wind not water
My next choice is D
Yes, D.
thx
You're welcome.
I apologize, but it seems that there is a duplicate answer in your options. Both options A and B mention "water dispersed seeds of the wildflower." However, I can help explain how one can arrive at the correct answer.
To determine which answer best explains why a species of wildflower native to Switzerland is observed growing in the wild in Montana, we need to consider the possible methods of dispersal and the specific factors involved.
Option A suggests that water dispersed the seeds of the wildflower. Water dispersal, or hydrochory, occurs when seeds are transported by water bodies such as rivers, streams, or even heavy rain. This method is common for some plant species, particularly those with buoyant or water-resistant seeds. However, Switzerland and Montana are located on different continents, and it is unlikely that water flowing directly between them could explain the movement of the seeds. Therefore, option A is not the best explanation.
Option C suggests that an animal ate the seeds and later dispersed them. Many plants rely on animals to eat their fruits or seeds and then move them to different locations through digestion or by adhering to their fur or feathers. If the wildflower species has edible fruits or seeds, it is possible that an animal in Switzerland ate them, traveled to Montana, and subsequently deposited the seeds through their droppings. This method of dispersal is known as endozoochory. Consequently, option C is a viable explanation.
Option D proposes that a human brought and dispersed the seeds. While human activity can lead to the unintentional or deliberate introduction of plant species to new areas, it is less likely to be the best explanation unless there is evidence of human involvement, such as intentional seed dispersal or gardening practices. Without any contextual information indicating human activity, option D is less likely.
Considering the reasoning above, option C (an animal ate seeds and later dispersed them) seems to be the best explanation.
Not B.
How could water disperse seeds over more than a thousand miles of land and across the Atlantic Ocean?
