Answer:
<u>Nutrition and health benefits</u> are the most likely motivation ,if a person decides to switch from drinking freshly squeezed orange juice to calcium-enriched orange juice after a yearly checkup,
Explanation:
As the Calcium enriched orange juice contains calcium almost equal to that of milk , hence it is an essential mineral which helps in building and maintaining strong bones and teeths.
It is also an excellent source of vitamin D helping the body to absorb more calcium . Thus providing excellent nutrition and health benefits.
Hence <u>Nutrition and health benefits</u> are the most likely motivation
The correct answer is (B) Photosynthesis and diffusion from the air
Dissolved oxygen enters the water from photosynthesis and through air. The The aeration of water can be caused by wind. From the air oxygen diffuse into the water and gets mixed in the it through circulation. The oxygen is also produced as a waste product of photosynthesis from blue-green algae, phytoplankton, etc which is added in water.
Answer:
A. It contains fewer volatile gases.
Explanation:
Mafic lava have a composition of about 45-55% silica with high amount of Fe, Mg, Ca.
The silica content is quite low compared to those of granitic magma whose silica content can reach up to about 60%.
What determines the viscosity of magma is basically the silica content of the magma and the temperature of the magma. Viscosity is the resistance to flow.
The higher the silica content, the lower the viscosity and the higher the amount of volatile gases. Such type of magma is the granitic magma. Granitic magma due to their viscosity flows slowly.
The lower the silica content, the higher the viscosity and the lesser the presence of volatile gases in them. Such an example is Mafic magma. Mafic magma flows very slowly with low amount of dissolved gases.
The answer would be Four.
