In developed nations, which nutrients are most apt to be lacking in a child's diet?
yKpoI14uk [10]
I believe that in developed nations, the nutrients that are most lacking in a child's diet are the; calcium, iron and zinc. Zinc is needed for the activity of more than 100 different enzymes in the body and plays a role in the immune function. It aids in the maintenance of healthy immune function in kids and may reduce the frequency of mild upper respiratory tract infections. Calcium keeps the bones healthy and teeth thus supporting the skeletal structure and function. Iron is an important component of hemoglobin.

Which sequence would be possible for a rock going through the rock cycle?
sdas [7]

D. metamorphic -> melting -> igneous -> erosion

Explanation:

The sequence that would be the best possible for a rock going through the rock cycle is metamorphic rocks melting to produce igneous rocks that are eroded.

  • The rock cycle shows the pathway by which different rock types are formed.
  • The origin of the formation of rocks starts with the production of magma.
  • Igneous rocks are formed from cooling and solidification of molten magma.
  • Metamorphic rocks are formed from the subjection of igneous and sedimentary rocks to high temperature and pressure.
  • Sedimentary rocks are formed from weathering, erosion, transportation and deposition of rocks.
  • Option D shows a metamorphic rock melting to give igneous rocks and the igneous rock is eventually eroded to form sedimentary rocks.
