The answer is The bone will become soft and Flexible
Inorganic component of bone would be consist of calcium and other deposition that makes the bone hard. The inorganic components are easily dissolved by acid which are used by osteoclast cell to remodel the bone. After the inorganic component removed, the bone will lose its hardness which make them more flexible.
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.
C. The cell must be a plant cell.
Only plant cells have cell walls. Bacteria cells and animal cells do not. Both animal cells and plant cells have membrane-bound organelles, but since the student saw a cell wall, it must be a plant cell.
Hope this helps! :)
Answer:
retroviruses
Explanation:
Retrovirus have an enzyme known as reverse transcriptase which allows them to synthesize DNA from RNA going against the central dogma of life which is the synthesis of RNA from DNA. This phenomenon is called teminism.
Answer:Through polymerization reactions.
Explanation:
This happens when monomers bond together to form a polymer.
