Answer:
The correct answer will be- 30 percent
Explanation:
Pregnancy loss or miscarriage is the natural death of the fetus or the embryo due to which the growing embryo is unable to survive.
About 70-80% of the miscarriage occurs between the first trimester or first 12 weeks of the pregnancy.
About 30-40% of all fertilized eggs get miscarried before pregnancy is known that is before implantation, 30% following implantation but prior to the missed period and 10% due to clinical miscarriage.
Thus, 30 per cent is the correct answer.
Answer:
Option D, a research paper published in an academic journal and an approved PhD dissertation
Explanation:
Nicholas must present her discovery with back up of strong literature review. This literature review must include papers published in good journals and only approved research dissertation.
An internet blog, news article and college level textbook are not considered as an approved study. These are not reviewed or approved by any peer group or associations.
Good papers of any good journals are reviewed and examined thoroughly by the peers and thus they can be used as a backup of any study.
Hence, option D is correct
D. Polar regions receive less solar energy and heat per unit area than tropical regions
Less direct sunlight means that there is less concentration of direct solar rays. This would influence temperature and would ultimately create weather, and since this pattern continues of switching direct ray latitudes, this would create climate zones all over the Earth, and similar ones with similar latitude and terrain.
The answer is A. Environmental conditions are not always right to produce flowers and seeds for sexual reproduction.
Most plants are able to reproduce either way because even if the conditions aren't right for the plant, it can still make more flowers so it doesn't die out.
I hope this helps! :D
