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.
Hawai'an volcanic islands
Hawai'an volcanic islands is not part of a convergent/subduction plate boundary.
<h3>What kind of plate boundary produces a sequence of volcanic islands?</h3>
- convergent boundary
- Along the convergent boundary, the new magma (molten rock) rises and may erupt violently to form volcanoes, frequently creating arcs of islands.
- Divergent plate boundaries are created when two plates are moving apart.
<h3>Why do volcanic chains and convergent borders coexist?</h3>
- Subduction causes melting that is partially molten.
- Water loss in the plate causes partial melting.
- Mantle material melts as a result and rises to the surface.
<h3>Which are the 4 types of convergent boundries?</h3>
- Divergent Plate Boundary.
- Convergent Plate Boundary.
- Transform Plate Boundary.
- Hotspot.

Red blood cells. Red blood cells (also known as erythrocytes) are cells in the blood that carry oxygen to all parts of the body. They are made in the spongy marrow inside the large bones of the body. Bone marrow constantly makes new red blood cells to replace old ones.
. In vertebrates, it is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water, and contains proteins, glucose, mineral ions, hormones, carbon dioxide, and blood cells themselves. Albumin is the main protein in plasma, and it functions to regulate the colloidal osmotic pressure of blood. The blood cells are mainly red blood cells, white blood cells and platelets. The most abundant cells in vertebrate blood are red blood cells. These contain hemoglobin, an iron-containing protein, which facilitates oxygen transport by reversibly binding to this respiratory gas and greatly increasing its solubility in blood. In contrast, carbon dioxide is mostly transported extracellularly as bicarbonate ion transported in plasma.
