This depends,
If you speaking in terms of the particle which carries "light" which gives us the ability to see than this particle is known as the 'photon'. This particle is massless and travels at the speed of light, 3x108 ms-1
the eyes are responsible for sight
It is the part of a molecule that is responsible for its color. When a molecule absorbs a wavelength of visible light and reflects or transmits others, this is when the molecule's color will appear.
The components of this molecule and the chemical bonding.
Aldehyde (functional group). The molecule responsible is cinnamaldehyde.
DNA is the molecule that is responsible for unity and diversity of life .
light
Functional groups are responsible for chemical reactions of molecules.
Proteins
Yes, Avery and his colleagues believed that the molecule responsible for the transfer of genetic information in their experiments with pneumonia-causing bacteria (the transforming principle) could be the molecule of the gene. They identified DNA as the molecule responsible for genetic transformation.
Chlorophyll is a molecule found in both animals and plants. In plants, chlorophyll is responsible for photosynthesis, while in animals, it serves as a crucial component of hemoglobin, the molecule responsible for transporting oxygen in the blood.
