Answer: D
Explanation: The important thing to notice in this question is that it's asking for the FORMATION of a NEW species. That detail automatically removes B as the answer, because, while an invasive species <em>could </em>lead to a new species, it isn't likely, and there's the fact that B is talking about the INTRODUCTION of a species that already exists.
A could be correct, but fertilizer isn't likely to lead to a new species, as well as C, which would lead to a LOSS in species and biodiversity.
D is correct because it is an example of Allopatric Speciation, which is when one species converges into 2 species because of a physical barrier.
I hope this helps. Have a great week!
Answer:
The correct option is <em><u>A. Over time, due to evolution by means of natural selection, resistant weeds survived, reproduced, and passed on their herbicide resistant genes. </u></em>
Explanation:
Herbicides can be described as substances which are used to kill unwanted plants such as the weeds. Nowadays, selective herbicides are produces which are effective in killing the weed species and do not harm the crop plants.
But over time, the weeds get resistant to the herbicide. As the theory of natural selection says, 'survival of the fittest', the herbicide which are resistant are better adapted to live hence, they pass their genes to the offsprings. This results in the production of more herbicide resistant weeds.
