Answer:
The correct answer is: it would create a polyploidy.
Explanation:
Polyploidy consists of an organism or a cell having more than 2 pairs of chromosomes, which in most species (including humans) is abnormal and not compatible with life.
An organism with 3 sets of chromosomes -69 in total- (instead of 46) has a triploidy. In humans, this happens when there's an extra haploid set from one of the parents.
An organism with 4 sets of chromosomes -92 in total- has tetraploidy.
These polyploidies result in miscarriage.
Answer:
Fossil records provide evidence of an increase in animal species at the same time that atmospheric oxygen levels increased.
Explanation:
A huge diversification among animal species occurred with the increase in the levels of atmospheric oxygen. The reason why the number of species increased drastically was that a whole new world opened up, the land. The land was open for exploitation and taking over, with every single niche free, so animals diversified and filled in pretty much all of the niches. The fossil records give us clues when this happened, as from only microorganisms there is a sharp rise in complex animals, coinciding with the increase of oxygen levels.
If it wasn't for the increase of atmospheric oxygen though this wouldn't have been possible. The oxygen in the atmosphere enabled animals to breathe on land. Also, it cooled off the global temperatures which were too high before the increase of atmospheric oxygen, making them suitable for life. And last but not least, the atmospheric oxygen resulted in the formation of the ozone layer, a layer that started to act as protection from the UV rays.
Answer:
-Seedless fruits can not be used to produce new progeny of any plant.
-Parthenocarpy is undesirable in nut crops because the seed is the edible part.
-Quality and Size of fruits get changed in case of Parthenocarpic fruits as compared to the normal state.
