For a human to survive we require amounts of glucose which is readily found in sugar. example-when people say their sugar levels are low they tend to be more exhausted and less energetic. this is actually a lack of glucose in the body and can be replaced by ingesting a amount of it. however glucose isn’t only found in sugar but can be found in a variety of foods. so sugar doesn’t give us energy - it’s the glucose within it.

Answer: D
Explanation:
Light waves travel in straight paths called rays. Unlike sound, where waves have to travel through matter to be heard, light waves do not have to travel through matter to be seen. Instead, rays travel in a straight path until they hit an object. A ray's straight path is the path of light

Explanation:
Mendeleev played an important role in the development of the modern periodic table. His periodic table was filled with gaps. He said that these gaps were elements that were yet to be discovered. He rightly predicted many elements which have now been discovered and fitted in their proper places in the periodic table.
He used the prefix ''eka'' to refer to elements whose properties were alike but were yet to be discovered at that time.
The compound named ekaboron which he predicted to have an atomic weight between 65 (zinc) and 75 (arsenic) with a valence similar to aluminum was later discovered in 1879 and properly named scandium.
