Spontaneous miscarriage in the first trimester is related to Chromosomal defects in the fetus. An estimated 15 to 20 percent of known pregnancies end in miscarriage, the loss of a pregnancy before the 20th week. Upto 70 percent of first-trimester miscarriages, and 20 percent of second-trimester miscarriages, are caused by chromosomal anomalies/abnormalities in the fertilized egg. Most often, it means that the egg or sperm had wrong number of chromosomes, and consequently the fertilized egg can't develop normally.
Answer:
182,500 units.
Explanation:
<em>The answer would be </em><em>182,500 units of mercury.</em>
<u>Assuming there is an average of 365 days in a years, 10 years is therefore equal to:</u>
10 x 365 = 3650 days.
<u>The stingray eats 50 clams per day. Hence, the total number of clams that would have been eaten in 10 years equals:</u>
3650 x 50 = 182,500 clams
<u>Each clam accumulated 1 unit of mercury in its body from the water it lives in and there is no loss of mercury between the clam and the stingray. Hence, the total number of units of mercury the stingray would have accumulated in 10 years equals:</u>
182,500 clams x 1 unit = 182,500 units of mercury.

The answer is fluorite. If a mineral cannot be scratched by a knife blade but can be scratched by quartz then its hardness is between 5 and 7 on mohs scale. A relative hardness value of 6.5 means that the mineral could scratch orthoclase but not quartz. Flourite hardness on mohs scale is 4, and therefore due to the very low hardness and perfect cleavage of Flourite, special care must be taken to ensure it doesn't get scratched or chipped. It cannot scratch the glass.
