The greater amount of eumelanin in darker skin protects folate from being broken down by UV radiation and thus increases fitness among populations in high-intensity UV areas. ... However, it does not explain why there is variation in human skin color.
It is very interesting how photosynthesis and cellular respiration<span> help each other. During photosynthesis, the </span>plant<span> needs carbon dioxide and water-- both of which are released into the air during </span>respiration<span>. And during </span>respiration<span>, the </span>plant<span> needs oxygen and glucose, which are both produced through photosynthesis!

Answer:
Attractive forces between particles.
Explanation:
Solids keep its shape and volume because of strong attractive forces between the particles.
Other options are incorrect:
Because there is no space between solid particles.
The shape of solid does not depend upon type of particles present.
The shape and volume of solids not depend upon the volume and shape of container.
Properties of solids:
Solids have definite volume and shape.
In solids molecules are tightly pack and very close to each other.
Their melting and boiling point are every high.
The densities of solids are also very high as compared to the liquid and gas.
There are very strong inter molecular forces are present between solid molecules.
