Answer:
its option A. bright tail feathers of peacocks during breeding season
Explanation:
We can infer of the two paragraphs that Geological movements are often hazardous when they happen quickly, and that the movement of plate boundaries does not always cause disaster.
The excerpt is telling us that "the <span>earthquakes caused a lot of damage, as well as dramatic changes to the local ecosystem", which is supporting the conclusion: "geological movements are often hazardous when they happen quickly."
But is also telling us that "</span>The slip caused several rock formations and structures to develop cracks. However there was no large-scale disaster or disruption.", which is supporting the conclusion: the movement of plate boundaries does not always cause disaster."
Answer:
A) The pollen grains will be pure red.
Explanation:
Plants have alternation of generations, this means that there are two different stages in their life-cycle: a sexual haploid (n) phase and an asexual diploid phase (2n). These phases occur in different individuals, so there is an haploid plant called gametophyte that carries gametes and after fecundation, it will rise a diploid sporophyte (asexual).
In seed plants, the sporophyte is the plant that we normally see, and the gametophyte is reduced into an organ of the sporophyte. The male gametophyte is the pollen that is produced in the sporangium in anthers (parts of sporophyte). When a pollen grain fecundes a female gametophyte (egg), it will produce a diploid embryo or new sporophyte.
Therefore, if the researcher exposes pollen to both stains, these grain will stain red, because red stain identifies gametophyte tissue.
