Answer:
A polysaccharide found in animals.
Explanation:
Biomolecules are the important chemical compounds present in the living organisms and responsible for all the functional activities of the body. Four important biomolecules are carbohydrates, proteins, fats and lipids.
Glycogen is a carbhydrate made of the polymer of the glucose linked through the glycosidic bonds. The glycogen acts as the energy source and present in animals mainly. Glycogen is mainly stored in the liver and the skeletal muscles of the animals.
Thus, the correct answer is option (a).
First, we determine the energy required to melt one gram of ice. This is given by:
Energy = mass * latent heat of fusion
Energy = 1 g * 334 J/g
Energy = 334 J
Next, we use Planck's equation which is:
Energy = number of photons * Planck's constant * speed of light / wavelength
334 = n * 6.64 x 10⁻³⁴ * 3 x 10⁸ / 5.49 x 10⁻⁶
n = 9.20 x 10²¹
9.20 x 10²¹ photons need to be absorbed by the ice.
Valence Electron is the outermost electrons, family(Alkali) 1 has 1 valence electrons and family(Alkaline) 2 has 2 valence electrons.
Hope this helps
Protons and neutrons make up most of an atom's mass. Electrons have almost no mass.
