Answer:
Linings of hollow organs
Explanation:
Smooth muscle cells are usually found in the lining of hollow organs such as all arteries and veins, wall of stomach, uterus, urinary bladder, digestive system etc. The cells of these linings are spindle shaped and consist of a nucleus at the center which lacks striations.
They work as a housekeeper and are under involuntary control except the heart. They lack striation because of irregular arraying of actin and myosin filament along the length of the cell.
The correct answer is AMDR or Acceptable Macronutrient Distribution Ranges.
DRI or Dietary Reference Intakes is defined as recommendent amount of energy, nutrients and other food components for healthy people to stay healthy and to prevent chronic disease risk, and deficiencies. DRI is set for each gender and age.
If enough ejecta (mainly ash) is sent into the upper atmosphere, the dust particles will block solar energy causing a decrease in temperature. This has happened in the past. Look for the year without summer caused by a volcanic eruption.
