Answer:
A. The fern transitioned from gametophyte generation to sporophyte generation.
Explanation:
Ferns undergo an ALTERNATION of GENERATIONS in their reproductive life cycle. That is, they alternate between an incospicuous gametophytic stage and a dominant sporophytic stage. The sporophyte produces haploid spores, which germinates into the gametophyte plant called PROTHALLUS.
The gametophyte produces gametes (male and female) which fuse together to form the diploid zygote, which eventually develops into the SPOROPHYTE plant via mitosis. In this question, the brown dots from the underside of a fern's leaves that Maria collected are the spores.
When she places them in a pot, the spores germinated into gametophyte stage, then formed sporophyte, which is the small leaves she noticed growing from the pot. From this, it can be observed that the fern is transitioning from GAMETOPHYTE generation to SPOROPHYTE generation.
The high-energy electrons produced by the chlorophyll are highly reactive so to move it from the chlorophyll to the other molecules it needs a carrier.
Answer:
The two population will become separate species due to allopatric speciation
Explanation:
Allopatric speciation is also known as geographic speciation. In this speciation two populations of the same species isolated geographically from each other which prevents gene flow between them and the two populations evolve separately and over time, it leads to the creation of a separate species.
So here as interbreeding within the hybrid zone of the mountain pass decreased over time so it will lead to speciation in these populations and they will evolve into two separate populations due to lack of gene flow as a result of geographical isolation.
