Sulfur is known as the essential nutrient for plant growth. Sulfur playing various important role in plants. About 90% of the sulfur is absorbed by the plants for the purpose of amino acids synthesis, known as the building blocks of proteins. Sulfur is important for the enzyme which is helping in the formation of the chlorophyll molecule. Sulfur is essential for the synthesis of oil crops.

In human body sulfur playing some essential role such as amino acid production which is converting into proteins and producing enzymes. Sulfur is important for insulin production, insulin allow the cells to use glucose as energy. Sulfur is found in most important antioxidant known as glutathione, which helping in the inhibition of oxidation of the other molecules and preventing from cell damage. Collagen provide skin strength and structure, sulfur is important for collagen synthesis as well.

Answer:

light is required to provide energy for photosynthesis

Explanation:

For photosynthesis to take place, it requires the presence of light and chlorophyll. The process has two stages; light and dark stage.

water→ hydrogen atoms + oxygen.

The hydrogen atoms produced enter the dark stage while oxygen is released in the atmosphere. In the dark stage, carbon dioxide combines with the hydrogen atoms to form simple sugar such as glucose.

Answer:

The correct option is D) The age-structure diagram would be column-shaped with all age classes approximately equal.

Explanation:

A zero population growth refers to a condition when the birth rate equals to the death rate. Social workers tends to find methods to attain zero population growth as such conditions provide economic stability. As the birth rate and the death rate will be equal hence the age structure diagram of such a population can be seen to be column shaped as they all will be equal.
