This may also cause the person decreased motility as they are experiencing a fright. The sympathetic nervous system controls a persons flight or fight response in the body. The correct answer is B.
Answer:
Green house gases are the type of gases present in the air which have the ability to trap heat of the earth's surface. Gases like carbon dioxide and methane are found naturally and are known to play an important role in earth's climate. If they are not found the earth' s climate would be too cold creating problem for survival of life on the earth.
These green house gases absorb the emit the radiation in the thermal infrared range. These gases act like a blanket and save earth surface from infrared radiation by absorbing them and prevent them from escaping out of the earth surface.
But now a days due to increased in the concentration of green house gases like carbon dioxide and methane due to pollution and deforestation causing a great problem called as green house effect which lead to global warming and it a great concern for all the people now a days.
Answer:
That happens during anaphase!
Hope this helped you! :)
<span>Equivalent millimoles HCl/mg sample = ( (concentration HCl in mmol/mL)(Volume HCl in mL) - (concentration NaOH in mmol/mL)(Volume NaOH in mL) ) / ( (1000 mg/g)(mass antacid sample in grams )
From this equation, then you will be guided.

Moles = Molarity * liters
But if we are calculating millimoles, we may use mL.
Using this:
Moles reacted with antacid = moles of HCl - moles of NaOH
Moles reacted = 0.4548 * 14.1 - 0.1048 * 14.6
Moles reacted = 4.88 millimoles
The mass of the tablet was 1.333 grams = 1333 mg
Millimoles of acid per mg tablet = 4.88/1333
There are about 0.0037 millimoles reacting per milligram of tablet.
