They're mineral ions.
Examples are calcium and iron
They can prevent diseases such as ricket (soft bones) and anaemia (not enough blood)
Impact the amount of carbon in the atmosphere, the biosphere, and the
hydrosphere
Explanation:
The processes of photosynthesis and cellular respiration play a major role in the carbon cycle.
Both these processes are interconnected where the products of a process become reactants of the other process.
Carbon dioxide and water released through cellular respiration become the reactants for photosynthesis which releases oxygen needed for cellular respiration.
The oxygen released is used by animals and human beings for respiration and releases carbon dioxide which is once again used by plants during photosynthesis. This gaseous exchange happening during these two processes helps to maintain atmospheric carbon dioxide levels stable.
In the biosphere, carbon is stored in the organic form in plants and trees. Plants absorb the external atmospheric carbon dioxide and convert it into organic form and store it as food by the process of photosynthesis.
In the hydrosphere, carbon is available as dissolved in water in the water bodies like ocean, rivers, etc. this carbon is absorbed by marine or aquatic plants to undergo photosynthesis and produce their own food. Again the organic carbon is formed and stored in the form of food which is used by other aquatic organisms.
Glucose is converted into energy with oxygen in the mitochondria
Answer:d. Digitizer
Explanation:
A digitizer is a device that is used along with the stylus. A digitizer is used to convert the hand drawn images into a format which can be used by the computer.
The images are drawn on the flat surface along with the stylus that appears on the screen of the computer monitor. This device is used as glass cover over the screen of the monitor. This device is used to convert the analog signal to digital signals. This is used in non-touch screen laptops and monitors.
On the basis of the above description, the digitizer is the device which can be used along with the stylus to manipulate the screen.
