Answer:supports the body
facilitates movement
protects internal organs
produces blood cells
stores and releases minerals
Explanation:
The skeletal system in animals helps in their movement, support and to maintain their shape.In humans ,it consists of bones,which works closely with the muscular system.unlike worms and arthropods that have hydrostatic and exoskeleton respectively, humans have endoskeleton.the bones have the following functions;
*It allows the animal move . The skeleton provides support for the body and through the flexible joints ,the body is able to move
*The skeleton protects the internal organs of the body by protecting them against impact.for examples,the ribs protect the lungs and the skull protects the brain.
*Certain cells in the bone produce immune cell and important components of the bone
*The bones also regulate the level of calcium in the blood
Answer:
Magnesium, calcium, phosphorous, sulfur these are essential nutrients for plants. These are required in trace quantity but are very important for plant life. Point A. will be correct answer.
Explanation:
As in B. starch n cellulose are composed of only carbon, oxygen and hydrogen.
As in C. These elements are not required on special occasion but are necessary throughout plant life.
As in D. C H N O is the primary component plants need but these secondary nutrients are equally necessary for growth n structure of plant.
<u><em>So answer A. Is the correct option.</em></u>
Calcium plays the most important role in structure formation of plants. Also act as messenger molecule in signaling. Deficiency of calcium caused wilting , weakened stem and ultimately death of plant.
Magnesium is the key element in chlorophyll molecule. It is necessary for chlorophyll formation.
Sulfur is another very important element in plant life, it is necessary for protein synthesis in plants.
Phosphorous plays an important role in process of cell devision , photosynthesis and respiration.
Potassium is very crucial in gaseous exchange ,it operates the opening and closing of stomata.
