"Altered ecosystems" is the one consequence of global warming among the following choices given in the question that <span>is described as having an increase in growing season, changes in migration, and loss of species. The correct option among all the options that are given in the question is option "D".</span>
<span>A mature sporophyte produces spores by meiosis, a process which reduces the number of chromosomes to half, from 2n to n. Because meiosis is a key step in the alternation of generations, it is likely that meiosis has a fundamental adaptive function. The nature of this function is still unresolved (see Meiosis), but the two main ideas are that meiosis is adaptive because it facilitates repair of DNA damages and/or that it generates genetic variation.
The haploid spores germinate and grow into a haploid gametophyte. At maturity, the gametophyte produces gametes by mitosis, which does not alter the number of chromosomes. Two gametes (originating from different organisms of the same species or from the same organism) fuse to produce a zygote, which develops into a diploid sporophyte.</span>
Amphibia,
Reptilia, Aves, and Mammalia are included in the group Tetrapoda. The
correct answer between all the choices given is the second choice. I am hoping
that this answer has satisfied your query and it will be able to help you in
your endeavor, and if you would like, feel free to ask another question.
