Answer:
The correct answer is hypothyroidism.
Explanation:
Iodine is one of the essential components that must be incorporated in the human diet as it plays an important role in the generation of thyroxine hormone secreted by the thyroid gland. This hormone monitors various functions in the body like it regulates and maintains the body's metabolism, and offers energy to various parts of the body.
In case, if the level of iodine diminishes in the body then it can result in low production of thyroxine hormone, which eventually results in a condition known as hypothyroidism.
Answer:
Matter cycles through an ecosystem through processes called biogeochemical cycles.
Explanation:
Photosynthesis
Plants build carbohydrates by taking in carbon dioxide from the atmosphere.
Carbon moves through the food chain
As organisms eat other organisms, carbon moves up the food chain. Molecules in the food that contain carbon transform into the organic molecules that make up the living body.
Carbon moves back to the environment
Organisms use food molecules, containing carbon, as a form of energy. The process of cellular respiration breaks down food molecules into carbon dioxide.
Contribution of industry
Humans contribute to moving carbon dioxide back into the atmosphere through the combustion of fossil fuels.
Use of fossil fuels
Today's fossil fuels were formed hundreds of millions of years ago by plants deposited in the Earth. The decomposition of the plants slowed down in such a way that their organic molecules are used for natural gas, coal and oil.
Diffusion into the air
From the oceans, carbon dioxide diffuses into the air. This creates a large amount of carbon, which is then taken in by plants to start the cycle over again.
Since biochemical function is determined largely by specific enzymes (proteins), different sets of genes must be turned on and off in the various cell types. This is how cells differentiate.
