Answer:
C. You can see the parts in a heterogeneous mixture but can't see them in a homogeneous mixture.
Explanation:
a heterogeneous mixture is in other words, the one that does not mix or is not uniformly combined, hence leading to the creation of layers of the substances used.
a homogeneous mixture is the one that completely dissolves, or mixes, or is uniformly combined.
Bones are made up of Calcium Phosphate given by the chemical formula, 
. When bones are kept in Hydrochloric acid, given by the chemical formula, HCl, they become soft because the calcium compound present in the bones changes its form. The following double displacement reaction takes place when the bones are kept in HCl,
---> 
Calcium chloride is water soluble, and gets washed away. This makes the bone thin and soft.
The ozonosphere is another term for the ozone layer, which is within the Earth's stratosphere. The ozone layer is responsible for absorbing most of the sun's ultraviolet (UV) radiation, thanks to its high concentration of ozone that is exclusive to this layer.
Answer:
A)
Explanation:
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.Also During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make SUGAR molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as GLUCOSE.
therefore the answer would be A
